In medical terms, weight-loss surgery is also called "bariatric surgery." Various weight-reducing surgical procedures are available, but they all help by limiting the amount of food you can eat. The shape and function of your digestive system are altered as a result of weight loss surgery and some procedures also restrict the number of nutrients that can be absorbed. This surgery can help you lose weight and manage obesity-related medical conditions. Diabetes, obstructive sleep apnea and risk factors for heart disease and stroke are among these conditions.

• Sleeve Gastrectomy: It is also known as the Gastric Sleeve, is a procedure in which approximately 85% of the stomach is removed, leaving 15% of the original capacity in a sleeve shape.
• Biliopancreatic Diversion: It reduces the size of the stomach like gastric bypass surgery), but there is also less absorption of ingested food within the intestine.
