Weight loss surgery, also called bariatric surgery, is a medical procedure designed to help people with severe obesity lose weight when diet and exercise alone haven’t been effective. It works by reducing the size of the stomach or altering the digestive process so that the body absorbs fewer calories. Common types include gastric bypass, sleeve gastrectomy, and adjustable gastric banding. These surgeries can improve or resolve obesity-related conditions such as type 2 diabetes, high blood pressure, and sleep apnea. The procedure is usually combined with lifestyle changes like diet, exercise, and counseling for long-term success.
There are several common procedures used for weight loss. The most common procedures are lapband, liposuction, and gastric bypass. Lapband can be reversed, liposuction needs to be done on a regular basis to be efficient and gastric bypass is permanent.
A recent study showed that less than 25% of weight loss surgery patients had had any net weight loss two years after surgery. In other words, people are expecting bariatric surgery (LapBand, gastric bypass, etc.) to be magical cures when in fact they aren't. This research proves that weight loss is simply about burning more calories each day than one is taking in.
