Bariatric surgery, also known as weight loss surgery, is a medical procedure performed on individuals who are severely overweight or obese.
The surgery involves altering the digestive system to reduce the amount of food that can be consumed, resulting in significant weight loss. While the procedure is considered a last resort for weight loss, it has become increasingly popular over the years due to its success in helping patients achieve their weight loss goals and improve their overall health.
Bariatric Surgery Overview
There are several types of bariatric surgery, each with its own unique benefits and risks. The most common types of bariatric surgery include gastric bypass, sleeve gastrectomy, and adjustable gastric banding.
- Gastric Bypass: This surgery involves creating a small pouch from the stomach and connecting it directly to the small intestine, bypassing a portion of the stomach and the first section of the small intestine. This restricts the amount of food that can be eaten and reduces calorie absorption.
- Sleeve Gastrectomy: In this procedure, a large portion of the stomach is removed, leaving a smaller sleeve-shaped stomach. This limits the amount of food that can be consumed and may also impact hunger-regulating hormones.
- Gastric Banding (Lap-Band): A band is placed around the upper part of the stomach, creating a small pouch that limits the amount of food that can be consumed. The band can be adjusted over time to control the amount of food intake.
- Biliopancreatic Diversion with Duodenal Switch (BPD/DS): This surgery combines a sleeve gastrectomy with rerouting of the intestines. It reduces the amount of food that can be eaten and the body’s ability to absorb calories and nutrients.
- Bariatric Revision Surgery: In some cases, individuals who have already undergone a bariatric surgery may require revision surgery due to complications, inadequate weight loss, or other reasons.
Bariatric surgery is typically recommended for individuals with a body mass index (BMI) of 40 or higher, or a BMI of 35-39.9 with significant obesity-related health issues, such as type 2 diabetes, hypertension, or sleep apnea. However, candidacy for surgery depends on various factors, including medical history, previous weight loss attempts, and overall health.
Bariatric surgery is typically recommended for individuals who have a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with other health conditions such as diabetes, high blood pressure, or sleep apnea.
Candidates for the procedure must also be committed to making lifestyle changes, including adopting a healthy diet and regular exercise routine.
