What is Sleeve Gastrectomy?
Sleeve gastrectomy is one of the most common surgical methods used in the treatment of obesity. In this procedure, approximately 80% of the stomach is removed, and the remaining part is reshaped into a tube-like structure. This reduces the stomach’s capacity and helps control the feeling of hunger.
Advantages
- Permanent weight loss
- Reduction in the feeling of hunger
- Improvement in conditions such as type 2 diabetes, sleep apnea, and hypertension
- Fast recovery and low risk of complications with the laparoscopic method
Who Is It Suitable For?
- Individuals with a Body Mass Index (BMI) of 35 or above
- Individuals with a BMI between 30 and 35 who have conditions such as diabetes or hypertension
- Individuals who cannot achieve permanent weight loss despite diet, exercise, and medication treatmentsr
Surgery Process and Recovery
- Method: Minimally invasive (laparoscopic) surgery
- Duration: 1–1.5 hours
- Recovery Time: Return to normal life within 1–2 weeks
- Gradual diet program (liquid → puree → solid foods)
- Vitamin and mineral supplementation
- Increase in physical activity
Frequently Asked Questions
What is sleeve gastrectomy?
Sleeve gastrectomy is a weight loss surgery in which approximately 80% of the stomach is surgically removed. The stomach is reshaped into a narrow, tube-like structure. As a result, both the stomach capacity is reduced and the secretion of the hunger-stimulating hormone ghrelin decreases.
Who can have sleeve gastrectomy?
It is generally suitable for individuals with a Body Mass Index (BMI) of 40 and above, or those with a BMI over 35 who also have additional conditions such as diabetes or hypertension. Eligibility is determined through a detailed health evaluation.
How long does the surgery take?
Sleeve gastrectomy usually takes between 45 minutes and 1 hour. It is performed using the laparoscopic (minimally invasive) method.
How long is the hospital stay?
Patients usually stay in the hospital for 2–3 days. In cases of a smooth recovery process, discharge takes place within a short time.
How long does it take to lose weight after sleeve gastrectomy?
Significant weight loss occurs within the first 6 months. It is possible to reach the target weight within 12–18 months. Results may vary depending on personal effort and adherence to the program.
Is there a risk of regaining weight after the surgery?
Yes. If unhealthy eating habits and a sedentary lifestyle continue after the surgery, there is a risk of regaining weight. Maintaining a proper diet and healthy lifestyle is essential for permanent results.
How does the diet change?
In the first weeks, the diet consists of liquids and pureed foods. Gradually, patients transition to normal foods. Attention should be paid to small portions, eating slowly, and maintaining proper hydration.
Is vitamin or mineral supplementation necessary after the surgery?
Yes. Especially during the first 6–12 months, supplements such as vitamin B12, iron, calcium, and vitamin D may be recommended. The need and dosage are adjusted according to medical check-ups.
Can women planning pregnancy undergo sleeve gastrectomy?
Yes, but pregnancy is not recommended until weight stabilization is achieved after the surgery (usually 12–18 months). Waiting is important for ensuring a healthier pregnancy process.
Is sleeve gastrectomy safe?
Sleeve gastrectomy performed with the laparoscopic method is very safe when carried out by experienced teams. However, as with any surgical procedure, there are certain risks, and it is important to discuss them in detail with your surgeon.
