When you get weight loss operation, your surgeon makes changes to your stomach or small intestine, or both. Here are three common methods surgeons typically use:
Adjustable Gastric Band
The surgeon puts a small band around the top of your stomach. The band has a small balloon inside it that controls how tight or loose the band is. The band limits how much food can go into your stomach. This surgery is done using a laparoscope.
This surgery removes most of the stomach and leaves only a narrow section of the upper part of the stomach, called a gastric sleeve. The surgery may also curb the hunger hormone ghrelin, so you eat less.
Your doctor may call this "Roux-en-Y" gastric bypass, or RYGB. The surgeon leaves only a very small part of the stomach (called the pouch). That pouch can't hold a lot of food, so you eat less. The food you eat bypasses the rest of the stomach, going straight from the pouch to your small intestine. This surgery can often be done through several small incisions using a camera to see inside (laparoscope). Doctors can also perform a mini-gastric bypass, which is a similar procedure also done through a laparoscope.With any type of weight loss surgery, you still must focus on eating a healthy diet and becoming more active as part of your lifestyle.
