Types of Bariatric Surgery
Short answer: The most common types of bariatric surgery are the gastric sleeve (removes part of the stomach), the bypass (small pouch plus intestinal reconnection) and the gastric balloon (a temporary, non-surgical device). The choice depends on BMI, health and goal, and is decided by the specialist.
Knowing the types of bariatric surgery helps you understand which option fits each patient.
Gastric sleeve
Removes about 70–80% of the stomach. A simple, widely used technique.
Gastric bypass
Creates a small pouch and reconnects the intestine; useful with diabetes or significant reflux.
Gastric balloon
A temporary device placed by endoscopy; for overweight or mild obesity.
Which one to choose?
It depends on BMI, related conditions and goal. The indication is medical.
