Bariatric surgery, also known as weight-loss surgery, involves procedures that help individuals lose weight by making changes to their digestive system. This is typically recommended for people with severe obesity or related health issues who haven’t achieved weight loss through diet, exercise, or other non-surgical methods. Common types of bariatric surgeries include:

• Gastric Bypass (Roux-en-Y): In this procedure, the stomach is divided into a small upper pouch and a larger lower section. The small intestine is then rerouted to the small stomach pouch, reducing the amount of food that can be eaten and the calories absorbed.
• Sleeve Gastrectomy: This involves removing a large portion of the stomach, leaving a small, sleeve-shaped stomach, which limits the amount of food intake and reduces hunger-stimulating hormones.
• Adjustable Gastric Band: A band is placed around the upper part of the stomach to create a small pouch, slowing food intake and creating a sense of fullness with smaller amounts of food.
• Biliopancreatic Diversion with Duodenal Switch (BPD/DS): This complex procedure involves removing part of the stomach and bypassing a large portion of the intestine, which results in reduced absorption of calories and nutrients.
