Turning good surgeons into great ones

What is weight loss surgery?

Weight loss surgery, also known as bariatric surgery, is a medical procedure performed to help individuals lose weight by altering the digestive system. These surgeries are typically considered for people with severe obesity who have not been successful in losing weight through diet, medication and exercise alone. The primary goal of weight loss surgery is to reduce the size of the stomach or restrict the amount of food the stomach can hold, leading to reduced food intake and, consequently, weight loss.

Types of weight loss surgeries

cehck

Gastric Bypass: This procedure involves creating a small pouch at the top of the stomach and connecting it directly to the small intestine. This bypasses a portion of the stomach and small intestine, limiting the amount of food absorbed and reducing calorie intake. It also gives rise to profound hormonal changes that are responsible for sustained weight loss results after this procedure.

Mini Gastric Bypass: This procedure involves creating a large pouch of the stomach and connecting it directly to the small intestine. This bypasses a portion of the stomach and small intestine, limiting the amount of food absorbed and reducing calorie intake. It also gives rise to hormonal changes that can cure diabetes permanently in a majority of cases.

Sleeve Gastrectomy: In this surgery, a large part of the stomach is removed, leaving a banana-shaped or sleeve-like structure. The reduced stomach size limits the amount of food that can be consumed, leading to weight loss.

Gastric Banding: This involves placing an inflatable band around the upper part of the stomach, creating a smaller pouch. The band can be adjusted to control the size of the opening between the two parts of the stomach, regulating the amount of food that can enter.
