Global Obesity Ranking: Fighting This Worldwide Crisis, Right Here in Istanbul!

Obesity: The Silent Pandemic of Our Time and Forever Clinica’s Expertise

Hello dear reader,

In today’s world, we face a health crisis that is often discussed but still not fully understood: Obesity! Perhaps some of you might think, “I’m just a little overweight, what’s the big deal?” But believe me, obesity is not just an aesthetic concern; it’s a colossal problem sweeping across the globe, threatening the health of billions. Data from the World Health Organization (WHO) starkly reveals this reality: obesity rates have nearly tripled in the last 50 years! This increase brings with it numerous insidious diseases, from diabetes to cardiovascular diseases, high blood pressure, and even certain types of cancer.

This is precisely where we, at Forever Clinica, step in. For years, we have given a new lease on life to thousands of individuals battling obesity who couldn’t achieve their desired results with diet and exercise alone. With our expert surgeons and experienced team, we are truly a benchmark in surgical solutions for obesity. In this article, we will delve into the global obesity ranking, examining which countries are at risk, exploring the causes of obesity, and discussing how surgical weight loss methods provide effective results. And remember, all our transformative procedures are performed with the highest standards, right here in Istanbul, Turkey! You are not alone in this fight; with the right information and the right steps, winning this battle is entirely possible!

Global Obesity Map: Which Countries Are Alarming?

While obesity is a problem that knows no geographical boundaries, countries’ lifestyles, dietary habits, and health policies significantly shape this picture. Let’s take a look at the countries at the top of the obesity list as of 2024 and try to understand why they are in this situation.

Pacific Islands: The Epicenter of the Crisis

Countries that top the obesity rankings are often small island nations in the Pacific Ocean. The underlying reasons for this situation are not very complex:

Nauru (61% Obesity Rate): This tiny island nation leads the list, with over 60% of its population struggling with obesity. The abandonment of traditional eating habits in favor of imported high-calorie fast-food products and a sedentary lifestyle have trapped Nauru in this grim situation. Just imagine, more than half of the population lives with obesity!
Cook Islands (55.9%): Following closely behind Nauru, the Cook Islands are battling similar issues. The widespread consumption of processed foods, replacing traditional diets with fast food and junk food, has driven obesity rates to incredible levels.
Palau (55.3%): Palau is experiencing the same scenario. The shift from traditional fishing and farming cultures to ready-made, high-calorie Western-style diets seriously threatens public health.
Marshall Islands (52.9%): Excessive consumption of sugary drinks, high-fat foods, and processed items is increasing obesity in the Marshall Islands. These island nations are living examples of how drastic changes in dietary habits can lead to devastating consequences.
Tuvalu (51.6%): Even in a fishing community, the widespread availability of convenience foods has propelled Tuvalu to the top of this list. The deterioration of their traditionally healthy diets has, unfortunately, resulted in obesity.

The Situation in Major Countries: USA and Mexico Lead the Way!

Beyond small countries like the Pacific islands, obesity rates are also remarkably high in some of the world’s largest economies.

USA (36.2%): The United States is one of the largest countries struggling with obesity globally. Fast-food culture, giant portions, high-sugar beverages, and a sedentary lifestyle have caused obesity to spread like an epidemic in the US. The prevalence of fast-food restaurants on every corner, portion sizes far exceeding European standards, and a high reliance on cars are among the most significant reasons for this picture.
Mexico (32.4%): The US’s neighbor, Mexico, is also seriously fighting obesity. High consumption of sugary drinks, increased demand for processed foods, and the abandonment of traditional diets are driving up obesity rates in the country.

The Situation in Turkey: At the Top in Europe!

And now, let’s talk about our home… Unfortunately, Turkey cannot remain outside this global crisis. With an obesity rate of 32.1%, Turkey has one of the highest obesity rates in Europe. This means that one out of every three adults is struggling with obesity. So, why is the situation like this for us?

Rapid Urbanization and Sedentary Lifestyle: The rapid increase in urbanization, people working more at desks, reduced walking habits due to public transportation or car use, all contribute to a lack of physical activity.
Unhealthy Eating Habits: The replacement of our traditional and healthy eating habits with fast food, ready-made meals, sugary drinks, and high-calorie snacks is one of the biggest factors in the spread of obesity. Unhealthy habits such as consuming packaged products in front of the TV after dinner, skipping meals, and irregular eating are unfortunately very common.
Psychological Factors: Intense work pace, stress, economic anxieties, and other psychological factors can trigger emotional eating disorders, paving the way for weight gain.

Why Is Obesity So Prevalent? A Deeper Look

The alarming increase in obesity rates is not due to a single cause. It’s a complex equation formed by a combination of many factors. Let’s take a closer look at the primary reasons leading to obesity:

The Reign of Fast Food and Processed Foods: One of the biggest nutritional problems of our time. These high-calorie, high-trans fat and saturated fat, sugar-laden, and nutrient-poor foods act almost like a weight-gain machine. Their affordability, easy accessibility, and quick consumption make them particularly appealing in busy urban life. When you consider the calories and saturated fat in a single fast-food meal, you can better understand how dangerous regular consumption can be.
Sedentary Lifestyle: The Curse of Modern Life: In the past, people were much more active. They worked in fields, walked long distances, and performed physically demanding jobs. Today, the situation is very different. Spending long hours sitting in offices, time spent in front of computers, watching television, driving everywhere… All of these dramatically reduce our energy expenditure. Lack of exercise leads to unburned calories being stored as fat. Just think about how much difference even a 30-minute brisk walk a day can make!
Genetic Factors: Destiny or Just a Predisposition? You’ve probably often heard the phrase, “Everyone in my family is overweight, so am I.” Yes, genetic factors can increase the risk of obesity. Certain genes can affect metabolic rate, appetite, and fat storage tendencies. However, genetics alone are not destiny. If there’s a history of obesity in your family, it simply means you need to be more careful. You can largely counteract genetic predispositions with healthy eating and regular exercise.
Psychological Factors: Emotional Eating and Stress: Eating isn’t just about satisfying physical hunger; it can also be a source of emotional comfort. Emotional states like stress, depression, anxiety, or boredom can lead to “emotional eating” in some people. In such cases, individuals turn to food to feel better, even when they’re not physically hungry. Sugary and fatty foods, in particular, provide a short-term sense of relief but lead to weight gain and larger problems in the long run. Seeking professional support is crucial in battling such eating disorders.
Socioeconomic Status: Is Healthy Eating a Luxury? It might sound surprising, but socioeconomic status also has an impact on obesity. Individuals with lower incomes can generally access cheaper and less nutritious processed foods more easily. Fresh fruits, vegetables, and quality protein sources are often more expensive. This situation can lead to unhealthy eating habits being more prevalent among lower-income groups. Additionally, their opportunities for physical activity might be limited due to safety concerns or transportation difficulties.

Obesity Surgery: A New Beginning with Forever Clinica in Istanbul!

So, what should individuals do who are unable to lose weight with diet and exercise, are tired of battling obesity, and need a permanent solution? This is where obesity surgery, when performed with the right patient selection and an experienced team, becomes a life-saving solution. At Forever Clinica, we combine the most current techniques and the most experienced surgeons in obesity surgery to offer our patients safe and effective treatment options. All these crucial procedures are performed by our expert team right here in Istanbul, Turkey, ensuring you receive world-class care in a city renowned for medical excellence. Remember, these surgeries not only help with weight loss but also improve or completely resolve many health problems associated with obesity.

Let’s take a closer look at the main obesity surgery methods we perform at Forever Clinica:

1. Sleeve Gastrectomy: The Most Popular Method

Sleeve gastrectomy is one of the most commonly performed obesity surgery methods today and is generally performed using a laparoscopic (minimally invasive) approach. This means it’s done through small incisions rather than a large cut.

How Is It Performed? Approximately 80% of the stomach (the fundus and corpus parts) is surgically removed, and the stomach is transformed into a thin, tube-shaped structure, resembling a banana. The remaining stomach volume is approximately 100-150 ml.
How Does It Work?
- Volume Restriction: This is its most prominent effect. Since the stomach volume is reduced, you feel full with much less food. Your portions naturally become smaller.
- Decreased Hunger Hormone: The removed part of the stomach produces a hunger hormone called “ghrelin.” Removing this section lowers ghrelin levels, thus reducing your appetite and making you feel less hungry.
- Metabolic Improvement: Sleeve gastrectomy also leads to positive changes in gut hormones, playing a significant role in controlling or completely resolving type 2 diabetes.
Who Is It Suitable For? It is a suitable option for individuals with a BMI of 40 or higher, or those with a BMI of 35-40 who have co-existing conditions (diabetes, hypertension, sleep apnea, etc.).
Advantages: Relatively shorter surgery time, no major changes to bowel anatomy, fewer vitamin and mineral absorption issues compared to gastric bypass.

2. Gastric Bypass (Roux-en-Y): One of the Gold Standards

Gastric bypass has been performed for many years in obesity surgery, and its effectiveness is well-proven. It can be preferred, especially for patients with high BMI and those with metabolic problems like diabetes.

How Is It Performed? This method involves a two-stage change:
1. Stomach Pouch Creation: A small pouch (approximately 30-50 ml) is created in the upper part of the stomach. This becomes your new stomach. The rest of the stomach is bypassed but remains within the body.
2. Intestinal Rerouting: A section of the small intestine is cut and reconnected to the newly created stomach pouch. This way, food bypasses a large part of the stomach and the first part of the small intestine, going directly from the new stomach pouch to the lower part of the small intestine.
How Does It Work?
- Restricting Food Intake: Food intake is restricted because the stomach volume is reduced.
- Reducing Absorption: Bypassing the first part of the small intestine reduces the absorption of nutrients and calories.
- Hormonal Changes: Similar to sleeve gastrectomy, positive changes occur in gut hormones. It has a very strong effect on diabetes, in particular.
Who Is It Suitable For? It can be suitable for individuals with very high BMI, severe type 2 diabetes, and those experiencing stomach problems like reflux.
Advantages: Very powerful weight loss, high success rate in treating obesity-related diseases (especially diabetes).
Disadvantages: A more complex surgery than sleeve gastrectomy, requiring lifelong vitamin and mineral supplementation (such as iron, B12, calcium, vitamin D).

3. Gastric Balloon (Non-Surgical Method): An Incision-Free Solution

The gastric balloon offers a temporary solution for patients who do not want to take surgical risks or are not suitable for surgery. This method is used as part of a comprehensive weight loss program.

How Is It Performed? The balloon is placed into the stomach using an endoscopic method (through a tube inserted orally) and then inflated with a special liquid (usually saline). This procedure takes about 15-20 minutes and is typically performed under sedation.
How Does It Work? It takes up space in the stomach, creating a feeling of fullness and reducing food intake. This helps with portion control.
Who Is It Suitable For? It is suitable for individuals with a BMI between 27-35 or those who do not want/cannot undergo surgery and aim for short-term weight loss. It usually remains in the stomach for 6 to 12 months before being removed.
Advantages: Non-surgical procedure, relatively less risky, quick to perform.
Disadvantages: Weight loss may not be as permanent as with sleeve gastrectomy or gastric bypass, side effects like nausea and vomiting can occur, and there is a risk of weight regain after the balloon is removed.

4. Duodenal Switch: For Severely Obese Patients

Duodenal switch is one of the most complex and effective methods of obesity surgery. It is typically preferred for patients with very high BMIs (50 and above) or those who have not achieved sufficient weight loss with other methods.

How Is It Performed? This surgery involves both stomach reduction (similar to sleeve gastrectomy) and creating a significant malabsorption in the intestines. A large part of the small intestine is bypassed, ensuring that food and digestive enzymes meet in a much shorter intestinal segment.
How Does It Work? It provides very powerful weight loss and has the strongest curative effect on metabolic diseases like type 2 diabetes.
Who Is It Suitable For? It is a last-resort option for severely obese patients.
Advantages: Most powerful weight loss and metabolic improvement.
Disadvantages: The most complex surgery, carries the highest risk for vitamin and mineral deficiencies, requires very strict lifelong supplementation and follow-up.

At Forever Clinica, all these surgeries are performed by our experienced and expert surgeons using the most modern technological equipment, safely and meticulously. Detailed pre-operative assessment, utmost attention during surgery, and comprehensive post-operative follow-up are indispensable for us. And again, all these procedures are conducted with the highest medical standards right here in Istanbul, Turkey, ensuring you receive top-tier care in a convenient and globally accessible location.

Frequently Asked Questions (FAQ): All Your Questions Answered!

It’s completely natural to have many questions if you’re considering obesity surgery. Here are the most frequently asked questions and Forever Clinica’s approach to them:

1. Who is eligible for obesity surgery?

Obesity surgery is not applied to every obese patient. Patient selection is made based on specific criteria:

Body Mass Index (BMI) of 40 or higher: Individuals in this category are considered “morbidly obese” and are generally suitable candidates for surgery.
BMI between 35-40 with co-existing conditions (comorbidities): Individuals with serious health problems associated with obesity, such as diabetes, hypertension (high blood pressure), sleep apnea, joint problems, or reflux, are also evaluated for surgery.
Failure to lose weight with diet and exercise: Patients who have tried physician-supervised diet and exercise programs for at least 6 months without success are suitable candidates for surgery.
Psychological suitability: Individuals who can adapt to lifestyle changes after surgery and are psychologically ready for the procedure are preferred.

Remember, at Forever Clinica, every patient undergoes a detailed evaluation process. With a multidisciplinary approach involving doctors from various specialties like internal medicine, psychiatry, and dietetics, we decide whether the surgery is suitable for you. This comprehensive assessment is performed by our dedicated team in Istanbul, Turkey, ensuring a holistic approach to your health.

2. How much weight can be lost after surgery?

This is one of the most frequently asked questions! Patients who undergo obesity surgery typically lose 60% to 80% of their excess weight. However, this is not solely the success of the surgery itself. The process is directly related to how well the patient adheres to diet and lifestyle changes after the operation. Regular exercise, following the dietitian’s recommendations, consuming a protein-rich diet, and drinking plenty of water accelerate weight loss and ensure its permanence. Weight loss is fastest in the first year, followed by weight stabilization in subsequent years.

3. Are there any risks associated with obesity surgery?

Like all surgical procedures, obesity surgeries have potential risks. However, thanks to modern surgical techniques, laparoscopic approaches, and experienced surgical teams, complication rates are quite low. Potential risks include bleeding, infection, leakage (from the intestinal or stomach connection site), anesthesia-related complications, and embolism (blood clot).

At Forever Clinica, we prioritize our patients’ safety above all else. Detailed examinations are performed before surgery, risk factors are identified, and transparent information about possible complications is provided. With an experienced team and proper patient selection, these risks are minimized.

4. How should nutrition be after surgery?

Post-operative nutrition is vital for the permanence of weight loss and your overall health. Support from a dietitian is essential during this process. Generally:

Initial Weeks (Liquid and Pureed Phase): For the first few days after surgery, only clear liquids are consumed, followed by protein-rich pureed foods. The goal is to allow the new stomach to heal and adapt to the system.
Gradual Transition to Solid Foods: After about 3-4 weeks, a transition to soft solid foods is made. Portions should be small, and food should be eaten very slowly.
Protein-Rich Diet: Protein intake is prioritized to prevent muscle loss and increase satiety.
Plenty of Water Intake: Sufficient water should be consumed between meals to prevent dehydration.
Vitamin and Mineral Supplements: Especially in surgeries that cause malabsorption, such as gastric bypass and duodenal switch, lifelong vitamin (like B12, vitamin D) and mineral (like iron, calcium) supplementation may be necessary.

Our dietitian will create a personalized nutrition plan for you and support you step-by-step throughout this process.

5. How much does obesity surgery cost in Turkey?

The cost of obesity surgery varies depending on the method used (sleeve gastrectomy, gastric bypass, etc.), the hospital where the surgery will be performed, the surgeon’s experience, the post-operative follow-up program, and the patient’s overall health condition. Therefore, it is not appropriate to give a definitive price.

At Forever Clinica, we offer affordable solutions without compromising on quality and safe service. During our pre-operative consultation, we transparently explain your personalized treatment plan and pricing details. Remember, your health is paramount, and making the right investment directly impacts your quality of life.

What is Sleeve Gastrectomy? Sleeve Gastrectomy Surgery

A New Beginning: Embracing a Healthy Life with Gastric Sleeve Surgery at Forever Clinica, Istanbul, Turkey!

Obesity… It’s one of today’s most insidious and widespread health problems. For many of us, it’s not just an aesthetic concern, but also the key to serious ailments ranging from diabetes to high blood pressure, sleep apnea to heart disease. Years of diets, endless exercise, and a lack of lasting solutions… If you feel lost in this vicious cycle, you’re not alone. But there’s no need to despair anymore, because at Forever Clinica in Istanbul, Turkey, we offer you the opportunity to make a brand new start with gastric sleeve surgery (sleeve gastrectomy).

So, what exactly is “gastric sleeve surgery”? Who is it a suitable solution for? Don’t worry, in this article, we’ll cover all your curiosities in the most sincere and understandable language, with all the details. If you’re ready, let’s take the first step towards a healthy and happy life!

What is Gastric Sleeve Surgery (Sleeve Gastrectomy)? The New State of Our Stomach

Now, let’s take a closer look at the technical side. Gastric sleeve surgery, as its name suggests, is a surgical procedure that transforms the shape of the stomach into a tube. The goal is to reduce the volume of the stomach and thus limit the amount of food you can eat.

Imagine: Our stomach normally resembles a large J-shaped pouch. In gastric sleeve surgery, approximately 70% to 80% of this large pouch is permanently removed. The remaining part takes on the shape of a thin, long banana or tube. This will be the “new state” of your stomach.

So, why is such a large portion removed? Is it just about reducing volume? Actually, no! There’s also a hormonal aspect to it, which is quite important. In the removed part of the stomach, especially in the upper part called the fundus, a hormone called ghrelin is produced. Ghrelin is commonly known as the “hunger hormone.” This hormone sends “time to eat!” signals to our brain and increases our appetite. Since this area is removed in gastric sleeve surgery, ghrelin hormone production is significantly reduced. The result? You’ll feel much less hungry, get full faster, and your portions will naturally shrink!

While all these procedures might sound intimidating, today, this surgery is performed using a laparoscopic method (keyhole surgery). This means that instead of large incisions in your abdomen, a few small holes are made. Through these holes, the surgery is performed with the help of special instruments and a camera. This makes the recovery process much faster and more comfortable.

Who is a Candidate for Gastric Sleeve Surgery? Are You the Right Person?

Gastric sleeve surgery is not an operation that just anyone can undergo. It’s a serious decision and offers the most effective solution for individuals who meet specific criteria. At Forever Clinica in Istanbul, we thoroughly evaluate each patient to determine if they are suitable for surgery. So, in general, who can be considered suitable for gastric sleeve surgery?

Individuals with a Body Mass Index (BMI) of 40 or higher (Morbid Obesity): If your BMI is over 40, meaning you are severely obese, gastric sleeve surgery could be a strong option for you. In this case, surgery is considered appropriate even if you don’t have any additional illnesses related to obesity.
Individuals with a BMI between 35-40 with additional health problems: If your BMI is between 35 and 40, and you have additional health problems related to obesity such as Type 2 diabetes, high blood pressure (hypertension), sleep apnea, joint problems, or high cholesterol, gastric sleeve surgery can be an ideal solution for both losing weight and getting rid of or alleviating the symptoms of these diseases.
Those who have struggled to lose weight for a long time and have not achieved results with diet and exercise: Have you tried various diets for years, joined gyms, tried to change your lifestyle, but haven’t been able to achieve significant and lasting weight loss? For some individuals, obesity can be too complex to manage with diet and exercise alone due to hormonal and metabolic imbalances. In this case, gastric sleeve surgery can provide the momentum you need.
Individuals between 18-65 years of age: Generally, gastric sleeve surgery is not recommended for individuals under 18 or over 65, except in special circumstances. However, flexibility regarding age can be determined after a doctor’s evaluation.
Individuals without serious health problems that would prevent surgery: You should not have any serious heart, lung, or kidney problems that would increase the surgical risk. Furthermore, it’s very important that you are psychologically prepared for the surgical process and the subsequent lifestyle changes.

Important Note: At Forever Clinica in Istanbul, the decision for surgery is not made solely based on your BMI. Our expert team determines the most suitable treatment method for you after comprehensive health checks, psychological evaluations, and a detailed consultation process. Before the surgery, you will definitely need to consult an endocrinologist, a psychologist, and a dietitian. This multidisciplinary approach ensures the safest and most successful outcome for you.

Advantages of Gastric Sleeve Surgery: Why Should You Choose This Surgery?

Gastric sleeve surgery not only helps you lose weight but also offers numerous advantages that significantly improve your quality of life:

Rapid and Permanent Weight Loss: This surgery generally enables you to lose a significant portion of your excess weight (typically 60-70%) within the first 1-2 years. This quick start boosts your motivation and facilitates your transition to a healthy lifestyle. Most importantly, it offers a permanent solution.
Appetite Control by Reducing Hunger Hormone: As mentioned earlier, the reduction in ghrelin hormone significantly suppresses your appetite. This way, you eat less naturally without the stress of “dieting,” and your craving for snacks decreases. This is a dream for many dietitians and weight loss experts!
Improvement or Complete Remission of Metabolic Diseases: After gastric sleeve surgery, there are incredibly positive effects on obesity-related diseases such as Type 2 diabetes, high blood pressure, sleep apnea, high cholesterol, joint pain, and some types of cancer. Many patients can stop their diabetes medication or normalize their blood pressure shortly after surgery. This is not solely due to weight loss; it is also related to the positive metabolic effects of the surgery.
Fast Recovery Thanks to Keyhole Surgery Technique: This surgery, performed using the laparoscopic method, is much less invasive than open surgery. This means less pain, a shorter hospital stay (usually 2-3 days), and a faster recovery. It’s easier to return to your daily life after surgery.
No Foreign Material Placed in the Stomach: Unlike some other bariatric surgery methods like gastric banding, gastric sleeve surgery does not involve permanently placing a foreign object in your body. This eliminates the risk of infection or complications related to a foreign body.
No Malabsorption in the Intestines: In some surgeries like gastric bypass, a part of the intestines is bypassed to reduce nutrient absorption. In gastric sleeve, there is no change in the structure of the intestines; only the stomach volume is reduced. This allows for natural nutrient absorption, and the risk of vitamin and mineral deficiencies is lower. Of course, you may still need supplements, but your likelihood of experiencing severe deficiencies due to malabsorption is reduced.
Psychological and Social Improvement: Losing weight is not just a physical change; it also positively affects your psychology and social life. It provides numerous psychological benefits such as increased self-confidence, easier participation in social activities, and feeling more energetic. The change you see when you look in the mirror will motivate and make you happy.

Surgical Process and Recovery Period: We Are With You Every Step of the Way

Gastric sleeve surgery is a comprehensive process, and at Forever Clinica in Istanbul, Turkey, we are proud to be by your side every step of the way. Here are the stages of this exciting journey:

1. Pre-Surgery Preparation: Step by Step to a Healthy Future

The pre-operative period is one of the keys to success. During this process, we work diligently to ensure your health and the safety of the surgery:

Detailed Medical Evaluation: First, your general health condition is thoroughly evaluated with comprehensive blood tests, electrocardiography (ECG), chest X-ray, endoscopy (stomach examination), and imaging methods such as ultrasound. Your heart, lung, and liver functions are checked. All additional diseases developed due to obesity are meticulously examined.
Multidisciplinary Approach: Before the decision for surgery is made, evaluations from a team of specialists are obtained. You will be asked to consult with an internal medicine specialist, an endocrinologist, a cardiologist, a pulmonologist, a psychologist, and a dietitian. This team assesses your suitability for surgery and how prepared you are for the post-operative period. Psychological counseling is critically important for preparing you for potential emotional changes after surgery.
Nutritional Counseling: Our dietitian plans your pre-operative diet. Generally, you will be asked to start a liquid or very low-calorie diet a few weeks before the surgery. This helps to shrink your liver and make the surgical field safer during the operation.
Lifestyle Changes: It’s essential to completely stop smoking and alcohol consumption before surgery. Smoking negatively affects wound healing and increases the risk of complications. Alcohol also poses a risk to liver health. It’s very important to strictly follow all lifestyle changes recommended by your doctor.
Information and Consent: All details of the surgery, its potential risks, and benefits are explained to you in detail. All your questions are answered, and any uncertainties you have are resolved. The process is completed with your signing of the informed consent form.

2. Surgery Day: A New Beginning

When surgery day arrives, it’s perfectly normal to feel excited and perhaps a little nervous. But as the Forever Clinica team in Istanbul, Turkey, we are here to make you feel safe and the process as comfortable as possible:

Preparations: Final pre-operative checks are performed. The anesthesiologist evaluates you and prepares you for surgery.
General Anesthesia: The surgery is performed under general anesthesia, meaning you are completely asleep during the operation and feel nothing.
Laparoscopic Method: Our surgeon makes small incisions (typically 4-5 incisions, 0.5-1 cm in size) in the abdominal area and inserts special instruments and a camera. The abdomen is inflated with carbon dioxide gas to provide the surgeon with working space.
Stomach Reduction: Under camera guidance, a large portion of the stomach is removed using special stapling devices. The remaining stomach takes on the shape of a thin tube. The removed stomach tissue is taken out of the body.
Duration: The surgery itself usually takes 1 to 1.5 hours. However, with pre-operative preparation and post-operative waking, it spans a longer time frame.
Post-Operative Monitoring: At the end of the surgery, you are taken to the recovery room and closely monitored for the first few hours. Your pain is managed, and necessary medications are administered.

3. Recovery and Nutrition Process: Building New Habits

The post-operative period is a critical time for you to adopt new habits. Your diet will gradually change, and you will need to strictly follow your doctor’s and dietitian’s instructions:

Hospital Stay: You usually stay in the hospital for 2-3 days after surgery. During this time, your pain is managed, the safety of the surgery is confirmed with necessary checks like a leak test, and initial fluid intake begins.
First 1-2 Weeks: Liquid Diet Period: For the first 1-2 weeks after surgery, you can only consume clear liquids. Water, sugar-free compote, strained soup, broth, herbal teas, and buttermilk are your main sources of nutrition during this period. This time allows your stomach to heal and adapt to its new volume.
2-4 Weeks: Transition to Pureed and Soft Foods: From the second week onwards, with your dietitian’s approval, you can transition to pureed and very soft foods. For example, pureed vegetables, yogurt, cottage cheese, well-cooked and mashed fish or chicken are suitable for this period. Your portions will still be very small.
From 1st Month Onwards: Gradual Transition to Solid Foods: Approximately one month after surgery, under the guidance of your dietitian, you will gradually start adding solid foods to your diet in small portions. However, these “solid foods” will be different from your normal foods. You will need to avoid hard-to-chew and difficult-to-digest foods like nuts and red meat for a while. Chewing every bite thoroughly, eating slowly, and not drinking liquids with meals are vitally important during this period.
Regular Check-ups: You will need to attend regular check-ups with your doctor and dietitian for the first year after surgery (typically at the first month, third month, sixth month, and first year). During these check-ups, your weight loss, vitamin and mineral levels, and overall health status will be evaluated.
Physical Activity: You should avoid strenuous exercise for the first few weeks. However, light activities like walking will support your recovery and weight loss. You can gradually increase your physical activity level with your doctor’s approval.
Vitamin and Mineral Supplements: After gastric sleeve surgery, some vitamin and mineral deficiencies may occur. Therefore, it is very important to regularly use supplements such as multivitamins, B12, Vitamin D, iron, and calcium as recommended by your doctor. These supplements play a vital role in keeping you healthy and maintaining your energy levels.

Risks of Gastric Sleeve Surgery and Things to Consider: Transparent Information

As with any surgical operation, gastric sleeve surgery also has some potential risks and points to consider. At Forever Clinica in Istanbul, Turkey, we consider it our duty to inform you transparently about this:

Infection, Bleeding, Leakage: As with any surgical procedure, there is a risk of infection and bleeding, but with modern surgical techniques and sterilization methods, these risks are minimal. One of the most important and rare risks is leakage. This is when there is a leak from the stapled line of the stomach. Although very rare, this condition can be treated with early diagnosis and intervention. A part of your hospital stay is dedicated to monitoring this leakage risk and taking necessary precautions.
Anesthesia Risks: Risks associated with general anesthesia exist in every surgery. However, our anesthesiologists meticulously evaluate your general health status to minimize these risks.
Vitamin and Mineral Deficiencies: After gastric sleeve surgery, your stomach volume is reduced, so you will consume less nutrients. This can lead to deficiencies, especially in vitamins and minerals like B12, Vitamin D, iron, folic acid, and calcium. Therefore, it is vitally important to regularly use the supplements recommended by your doctor and dietitian for life. These deficiencies should be monitored with regular blood tests.
Insufficient Weight Loss or Regain: Gastric sleeve surgery is not a “magic wand.” After surgery, you must follow the diet plan recommended by your dietitian, engage in regular physical activity, and maintain lifestyle changes. If you revert to your old unhealthy eating habits after surgery, the stomach can stretch a bit, and unfortunately, you may regain weight. Therefore, commitment and discipline are very important in the post-operative period. At Forever Clinica, we continue to provide you with psychological and nutritional support throughout this process.
Gastric Reflux: Some patients may experience reflux (heartburn) complaints after surgery. This condition can usually be controlled with medication.
Dumping Syndrome (Rare): This syndrome can occur, especially with the rapid consumption of very sugary or fatty foods. It manifests with symptoms such as nausea, dizziness, palpitations, and sweating. Although it is rarer in gastric sleeve than in gastric bypass, it can be prevented by paying attention to your eating habits.

Remember, at Forever Clinica in Istanbul, Turkey, we use the most modern techniques to minimize these risks, and our experienced surgeons and healthcare team meticulously follow you before, during, and after surgery. When the balance of surgical risks and benefits is well evaluated, the risks of obesity-related health problems can be much higher than the risks of surgery.

Frequently Asked Questions (FAQ): Answers for Everything on Your Mind!

We’ve compiled and answered the most frequently asked questions about gastric sleeve surgery for you:

1. How much weight does gastric sleeve surgery help you lose?

Weight loss after surgery varies from person to person, but you are generally expected to lose 60% to 70% of your excess weight. For example, an individual weighing 150 kg with an ideal weight of 70 kg has 80 kg of excess weight. In this case, the goal is to lose approximately 48 kg to 56 kg. Remember, this is just an average, and your weight loss rate may vary depending on your metabolism, eating habits, and physical activity level. The largest and fastest weight loss usually occurs within the first 12-18 months after surgery.

2. Can I exercise after surgery?

Absolutely yes! Exercise is an important part of supporting weight loss and adopting a healthy lifestyle after surgery. However, you should avoid strenuous exercise for the first month after surgery. During this period, it’s important for your wound healing to be complete. With your doctor’s approval, you can start light walks and low-intensity exercises. After the first month, you can gradually increase your exercise intensity and transition to activities like Pilates, swimming, and cycling, according to your doctor’s recommendations. Remember, exercise is important not only for weight loss but also for preserving muscle mass, boosting metabolism, and improving your overall health.

3. Does the stomach stretch again?

This is one of the most frequently asked questions. Yes, the stomach can stretch a bit with excessive and irregular eating. However, this usually does not mean it will return to its pre-surgery size. The stomach is an elastic organ, and with continuous overeating, it can stretch over time. Therefore, it is very important to strictly follow the diet plan recommended by your doctor and dietitian, control portions, eat slowly, and not skip meals. Maintaining the new eating habits you gain after surgery is key to long-term success. Remember, gastric sleeve surgery gives you a “tool,” but how you use that tool is entirely up to you.

4. Is gastric sleeve surgery reversible?

No, gastric sleeve surgery is an irreversible operation. This is because a large portion of the stomach is physically removed and taken out of the body during the surgery. Therefore, a very well-considered and conscious decision must be made before the surgery. Being an irreversible procedure further emphasizes the importance of adapting to lifestyle changes after surgery and long-term follow-up.

5. When should I stop smoking and alcohol consumption?

It is critically important to completely stop smoking and alcohol consumption at least 1 month before surgery. Smoking slows down wound healing, increases the risk of infection, and can lead to anesthesia complications. Alcohol can irritate the stomach lining and negatively affect post-operative healing. It is also recommended to avoid alcohol and smoking for a long period (usually the first year) after surgery. Your doctor will give you detailed information on this. Adhering to this rule is very important for healthy recovery and long-term success.

6. Can pregnancy be considered after surgery?

Yes, pregnancy can be considered after gastric sleeve surgery, but it is recommended to wait at least 12-18 months after surgery. During this time, it is important for your weight loss to stabilize and for your body’s vitamin and mineral balance to be established. When considering pregnancy, you must consult your doctor, and a special monitoring and nutrition plan should be created during pregnancy. These precautions are vitally important for a healthy pregnancy.

7. Does hair loss occur after surgery?

Yes, some patients may experience temporary hair loss in the first few months after surgery. This is usually associated with rapid weight loss, changes in protein intake, and vitamin and mineral deficiencies. However, don’t worry, this is usually temporary and can be controlled with proper nutrition and supplements. Your dietitian will help you increase your protein intake and regularly use the necessary supplements.

8. When can I return to my normal life?

Even after being discharged from the hospital, it’s important to rest at home for the first few days. The time it takes to return to work and daily activities varies depending on the physical intensity of your job and your personal recovery speed. Generally, you can return to a desk job within 1-2 weeks. For jobs requiring heavy physical activity, this period may be longer. Your doctor will determine a specific return-to-activity schedule for you.
