Bariatric surgery is a type of weight loss surgery that aims to help individuals who are severely overweight or obese.

It involves making changes to the digestive system to limit the amount of food you can eat and/or the way that your body absorbs nutrients. Bariatric surgery is often recommended for individuals who have tried and failed to lose weight through diet and exercise alone.

Types of Bariatric Surgery

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

Gastric Bypass Surgery
Gastric Sleeve Surgery
Adjustable Gastric Band
Biliopancreatic Diversion with Duodenal Switch

Your surgeon will recommend the most appropriate type of bariatric surgery for you based on factors such as your overall health, body mass index (BMI), and weight loss goals.

How Does Bariatric Surgery Work?

The specific mechanisms of bariatric surgery depend on the type of procedure performed.

In general, bariatric surgery works by either reducing the size of the stomach, limiting the amount of food it can hold, or by bypassing a portion of the small intestine, thereby reducing the absorption of calories and nutrients.

In gastric bypass surgery, the surgeon creates a small pouch at the top of the stomach, which is then connected directly to the small intestine. This reduces the amount of food you can consume and limits the absorption of calories and nutrients.

In gastric sleeve surgery, approximately 80% of the stomach is removed, leaving behind a smaller, banana-shaped stomach. This reduces the amount of food you can eat and also affects hormones related to hunger and satiety, leading to decreased appetite.

Adjustable gastric band surgery involves placing a silicone band around the upper part of the stomach, which creates a small pouch. The band can be adjusted to control the amount of food that can enter the stomach and affects feelings of fullness.

Biliopancreatic diversion with duodenal switch is a complex procedure that involves both gastric sleeve surgery and rerouting the small intestine. It limits the amount of food you can eat and reduces the absorption of calories and nutrients.

Post-Surgery Recovery and Lifestyle Changes

Engage in regular exercise – incorporating physical activity into your daily routine is crucial for weight loss, muscle toning, and overall health
Attend follow-up appointments – regular visits with your healthcare team will help monitor your progress, adjust any necessary medications, and address any concerns
