5 Types of Weight Loss Surgery and How They Work

Weight loss surgery, also known as bariatric surgery, is a medical procedure that helps people lose weight by reducing the size of the stomach or bypassing parts of the digestive system. Weight loss surgery is an option for those who have tried and failed to lose weight through other methods, such as diet and exercise. In this article, we’ll explore 5 types of weight loss surgery and how they work to help you understand the different options available.

1. Gastric Sleeve Surgery

Gastric sleeve surgery involves removing a portion of the stomach to create a smaller, tube-like stomach. This limits the amount of food that can be eaten at one time, leading to a decrease in overall caloric intake. Gastric sleeve surgery also reduces the production of ghrelin, a hormone that stimulates appetite.

2. Gastric Bypass Surgery

Gastric bypass surgery involves creating a small pouch at the top of the stomach and attaching it directly to the small intestine. This limits the amount of food that can be eaten at one time and reduces the absorption of calories from food. Gastric bypass surgery also reduces the production of ghrelin, leading to a decrease in appetite.

3. Adjustable Gastric Banding

Adjustable gastric banding involves placing an adjustable band around the top portion of the stomach, creating a small pouch. The band can be tightened or loosened as needed to control the amount of food that can be eaten. Adjustable gastric banding does not involve cutting the stomach or rerouting the digestive system.

4. Biliopancreatic Diversion with Duodenal Switch

Biliopancreatic diversion with duodenal switch involves removing a portion of the stomach and rerouting the small intestine to reduce the absorption of calories and nutrients. This procedure is typically reserved for those who are severely obese and have not had success with other weight loss methods.

5. Vertical Banded Gastroplasty

Vertical banded gastroplasty involves creating a small pouch at the top of the stomach and placing a band with a small opening around the pouch. The opening restricts the amount of food that can be eaten at one time. Vertical banded gastroplasty is not commonly performed today, as it has a higher risk of complications than other weight loss surgeries.

In conclusion, weight loss surgery is a medical procedure that helps people lose weight by reducing the size of the stomach or bypassing parts of the digestive system. Gastric sleeve surgery, gastric bypass surgery, adjustable gastric banding, biliopancreatic diversion with duodenal switch, and vertical banded gastroplasty are the five types of weight loss surgery commonly used today. Each type of surgery has its advantages and disadvantages, and it’s essential to understand the differences between them to choose the appropriate option for a particular individual. Weight loss surgery should be considered as a last resort for those who have tried and failed to lose weight through other methods, and it should be done under the supervision of a qualified medical professional.
