What is obesity surgery?

Obesity surgery, also known as weight loss surgery or bariatric surgery, is a surgical procedure that helps people with severe obesity lose weight and improve their health. It is typically reserved for people who have not been able to lose weight through diet and exercise alone, and who have a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with obesity-related health problems.

There are several types of obesity surgery, each with its own benefits and risks. The most common types are:

* Roux-en-Y gastric bypass (RYGB): This is the most common type of obesity surgery. It involves creating a small stomach pouch and connecting it directly to the small intestine, bypassing most of the stomach and the first part of the small intestine. This reduces food intake and absorption, leading to weight loss.

* Sleeve gastrectomy (SG): This procedure involves removing a large portion of the stomach, leaving a narrow sleeve. This reduces the size of the stomach and limits food intake, leading to weight loss.

* Adjustable gastric banding (AGB): This procedure involves placing an adjustable band around the upper part of the stomach, creating a small pouch. The band can be tightened or loosened to restrict food intake, leading to weight loss.

Obesity surgery can be a life-changing procedure for people with severe obesity, leading to significant weight loss, improved health, and a better quality of life. However, it is important to note that it is a major surgery and there are risks involved, including the risk of infection, bleeding, and blood clots. It is important to discuss the risks and benefits of obesity surgery with a doctor to make an informed decision about whether or not it is the right choice for you.
