Stomach surgery, also known as bariatric surgery, is an option to promote weight loss for those who are severely obese.

These surgeries use different techniques to reduce the size of the stomach. After the surgery, a person should feel fuller faster, eats less, and loses weight. These surgeries help battle obesity by altering the body's digestion and absorption of food.

Keep in mind, all forms of weight-loss surgery are major procedures that can lead to serious risks and side effects. Patients must also make permanent changes to diet and adopt regular exercise to help ensure the success of bariatric surgery.

Gastric bypass and Laparoscopic gastric banding are the most common weight-loss surgeries.

Laparoscopic adjustable gastric banding is the most common "restrictive" surgery and can lead to a loss of about 40% of excess weight, on average. Gastric banding is considered the least invasive weight-loss surgery. The procedure can be reversed if necessary. Over time, the stomach generally returns to its normal size.

The usual procedure is stomach stapling, which reduces the size of your stomach and bypasses a large area of the small intestine. This can bring incredible results over time. Since you can only eat small amounts of food, the weight loss is dramatic.
