What is Sleeve Gastrectomy?

Sleeve gastrectomy is a procedure in which approximately 75-80% of the stomach is removed laparoscopically, leaving a narrow, tube-shaped small stomach behind. The remaining stomach volume is about 100-150 mL.

The surgery has a dual effect by both reducing portion size and reducing the production of the appetite hormone ghrelin. As a result, the patient reaches satiety with very small amounts of food, and the constant feeling of hunger disappears.

As the most commonly performed bariatric surgery method worldwide, sleeve gastrectomy is preferred because it is technically simpler than gastric bypass. Because no intestinal rerouting is performed, the risk of vitamin deficiency is lower than with bypass.

Symptoms

Sleeve gastrectomy is the surgical treatment of morbid obesity, not of a disease
Fluid restriction and pain may occur in the first weeks after surgery
Gastric reflux (especially in the first months) may develop in some patients
Rapid satiety and dietary change with small portions
Increased energy and ease of movement with weight loss

Risk Factors

BMI ≥40 kg/m² or ≥35 kg/m² with accompanying metabolic diseases
Cardiopulmonary diseases with high surgical risk
History of gastric cancer or serious gastric pathology
Severe gastroesophageal reflux (bypass may be more appropriate)
Psychiatric contraindication

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • If bariatric surgery criteria are met (BMI≥40 or ≥35+comorbidity)
  • If weight loss goals cannot be achieved with conservative methods
  • If there is severe reflux, vomiting, or weight regain after surgery
  • If long-term follow-up has been discontinued and nutritional problems have emerged

Treatment Methods

01
Laparoscopic sleeve gastrectomy: stapling and removal of the greater curvature of the stomach under CO2 pneumoperitoneum with 4-5 ports
02
At least 2 weeks of low-calorie diet before surgery to reduce liver volume
03
Progressive feeding protocol after surgery: liquid → puree → soft → normal diet (total 4-8 weeks)
04
Lifetime supplementation of vitamins A, D, E, K, iron, B12, and folic acid
05
Regular follow-up with endocrinology and dietitian
06
Psychological support and exercise program
