Gastric Sleeve Surgery in Turkey
Gastric sleeve surgery is one of the most effective methods used in weight loss surgery and involves removing around 75–80% of the stomach. With a smaller stomach, patients naturally consume less food and feel full more quickly, which contributes significantly to long-term weight loss. As the stomach becomes smaller, levels of the hunger hormone ghrelin decrease, reducing appetite and supporting improved metabolic control.
Lower ghrelin levels also help decrease insulin resistance, which is especially beneficial for patients with prediabetes or type 2 diabetes. At Turkey Bariatrics, we perform approximately 300 gastric sleeve surgeries per year, ensuring a high level of expertise and consistent outcomes. If you are considering a gastric sleeve surgery in Turkey, feel free to request a free and non-binding consultation. Our team will be happy to assist you.
Candidates for Gastric Sleeve Surgery in Turkey
Gastric sleeve surgery is recommended for individuals who have previously attempted to lose weight through diet and exercise but have not achieved lasting success. Candidates should also be ready to make long-term lifestyle changes to support a healthier way of living after the procedure. These changes play a crucial role in maintaining the results of the operation.
Another requirement for a gastric sleeve surgery in Turkey is your Body Mass Index (BMI). You must have a BMI of 30 or above, which places you within the eligibility range for metabolic surgery. If you are unsure whether you are a suitable candidate, you can calculate your BMI online or reach out to our team. Our experienced patient manager will guide you through all the necessary information.
Benefits and Advantages of Gastric Sleeve Surgery
Most patients lose around 60–70% of their excess weight within the first year after a gastric sleeve surgery in Turkey, and many continue to lose more depending on their lifestyle habits. The procedure not only supports weight loss but also leads to significant improvements in health conditions linked to obesity. These include hypertension, type 2 diabetes, sleep apnoea, high cholesterol, joint pain, and even infertility.
Compared with other procedures, a gastric sleeve surgery is less complex and generally associated with fewer side effects than a gastric bypass. Unlike a gastric band or gastric balloon, no foreign object is placed inside the body. This makes gastric sleeve surgery one of the most preferred options for patients seeking effective and sustainable weight loss.
Recovery and Nutrition After Gastric Sleeve Surgery
The surgery typically lasts 1.5–2 hours, and most patients are encouraged to start walking within 6–8 hours after the operation. Light walking during your hospital stay is essential, as it helps reduce gas-related discomfort and supports early recovery. The day after surgery, a leak test is performed to ensure safety before you begin consuming fluids.
After the leak test, you will start a liquid diet phase lasting the first 10 days. During this period, you may consume soup, milk, fruit juice and yoghurt. You will receive detailed nutritional guidance from our team to help you adopt a healthy lifestyle after your surgery. Most patients can return to work within one week, and after the first month, you may resume gym activities, avoiding abdominal exercises and heavy lifting.
Risks and Complications of Gastric Sleeve Surgery
Although gastric sleeve surgery is considered a safe procedure, all surgical operations carry certain risks. Possible complications include bleeding, infection, reactions to anaesthesia, blood clots, and a leak from the staple line. These risks are monitored closely by the medical team to ensure prompt intervention if needed.
Long-term side effects can include malnutrition, vitamin deficiencies, heartburn, reflux and temporary hair loss. These issues are usually manageable with medication adjustments and proper nutritional support. Supplementation—especially zinc, iron, and multivitamins—may be required to maintain healthy recovery and prevent deficiencies.
Frequently Asked Questions About Gastric Sleeve Surgery
How much weight can I lose after a gastric sleeve surgery?
Most patients lose 60–70% of their excess weight within one year after a gastric sleeve surgery in Turkey. The exact amount varies depending on lifestyle changes, nutrition and activity levels.
Will I experience pain after gastric sleeve surgery?
It is common to experience mild pain and nausea, which can be easily controlled with medication. As harmless gas is used to inflate the stomach during surgery, bloating and flatulence may occur. Gentle walking helps relieve these symptoms.
How much does a gastric sleeve surgery in Turkey cost?
The cost of gastric sleeve surgery in Turkey varies depending on the hospital, location, surgeon’s experience, medical equipment and individual needs. Prices typically range between £2,500 and £3,500.
Will my stomach grow again after a gastric sleeve surgery?
The stomach can expand or contract based on food intake. If postoperative dietary guidelines are not followed, the stomach may stretch slightly, but it will not return to its original size.
Can I get pregnant after a gastric sleeve surgery?
We expect patients to reach their ideal weight within 12 months. Pregnancy is recommended only after weight stabilises, as rapid weight loss or vitamin deficiencies may negatively affect both mother and baby.
How long do I need to stay for a gastric sleeve surgery in Turkey?
You will need to stay for five days in total—three nights in the hospital followed by one night in a hotel before travelling home.
Does hair loss occur after a gastric sleeve surgery?
Temporary hair loss can occur due to reduced food intake and rapid weight loss, typically between months 3 and 6. This usually resolves once weight stabilises. Vitamin and protein supplements may be required, with zinc and iron deficiencies being the most common causes.
