Sleeve Gastrectomy

Definition

A surgical intervention where approximately 80% of the stomach is removed to reduce its capacity, causing a faster sensation of fullness.

How it works

Sleeve gastrectomy is a restrictive surgery that transforms the stomach into a thin, tubular-shaped sleeve. Approximately 80% of the stomach is surgically removed, reducing its capacity from 1500 ml to approximately 150-200 ml. This intervention does not affect intestinal absorption, unlike bypass surgery. The patient feels full much faster with reduced portions. It is an irreversible intervention that usually leads to a weight loss of 50 to 70% of the excess weight within 18 to 24 months.

Role

Mechanically limits food intake by reducing stomach capacity.

Examples

• Sensation of fullness after consuming 100-150 ml of food
• Weight loss of 25-35 kg in a year
• Decreased appetite
• Improved quality of life

Recommendations

Eat slowly and chew food thoroughly to maximize fullness. Avoid greasy, succulent, and carbonated foods that cause discomfort. Complete your diet with vitamin B12 and calcium since absorption may be slightly reduced.

Key takeaway

Sleeve gastrectomy offers effective weight loss by simple reduction of gastric volume, with fewer nutritional complications than bypass surgery.
