What are the different types of bariatric surgery?

Bariatric surgery alters the digestive system to help obese people lose weight. Different types of bariatric surgery have different benefits and drawbacks. Patient health, BMI, and preferences determine operation decision.

Gastric bypass is a frequent bariatric operation. This includes developing a tiny pouch on top of the stomach that connects to the small intestine. By bypassing part of the stomach and the early part of the small intestine, this treatment limits food intake and nutritional absorption. Gastric bypass surgery reduces weight and improves obesity-related diseases like type 2 diabetes and high blood pressure.

Sleeve gastrectomy is another bariatric surgery. This treatment removes a major section of the stomach, leaving a sleeve-shaped stomach. Weight reduction occurs because the smaller stomach limits food intake. This procedure affects hunger and satiety hormones, controlling appetite. Sleeve gastrectomy is less invasive than gastric bypass surgery and improves metabolic health and weight loss.

Bariatric surgery using an inflatable band across the upper stomach is called adjustable gastric band. Adjusting the band limits food intake by reducing stomach hole size. The adjustable gastric band does not cut or reroute the digestive system like gastric bypass or sleeve gastrectomy. This technique is adjustable and removable. However, it may not lose as much weight as other bariatric surgeries.

A less common bariatric surgery is the duodenal switch. This entails removing part of the stomach and rerouting the small intestine to separate food and digestive juices. This significantly reduces calorie absorption. Patients with significant obesity or uncontrolled diabetes should consider the duodenal switch. It can reduce weight and improve obesity-related health, but it is more complicated and riskier than other bariatric surgeries.

Finally, several bariatric surgeries can assist obese people lose weight and improve their health. Each surgery has pros and downsides, and the patient’s health and preferences determine the option. Bariatric surgery candidates should visit with a doctor to identify the best option.
