When you have reached obesity, weight loss can become very difficult to do on your own. Speak with a weight loss doctor Houston residents trust for weight-loss (bariatric) surgery to lose weight and reduce your risk of medical problems. Bariatric surgery can help you lose weight in the following ways:
- Restriction. Surgery can physically limit how much food your stomach holds, which helps you reduce the total calories you consume.
- Surgery shortens or bypasses part of your small intestine, reducing the total calories and nutrients your body absorbs.
Types of Bariatric Surgery
To achieve these results, ask a weight loss doctor Houston residents count on for results which surgical method is ideal for you. Four common types of weight-loss surgery include:
- Gastric bypass
- Gastric banding
- Sleeve gastrectomy
- Duodenal switch with biliopancreatic diversion
Closer Look at Surgery Types that Help You Lose Weight
Visit your surgeon’s office and get to know them so that you feel more comfortable about the surgery. It also helps to know what your choices are before consulting with your doctor. Here’s a little more information about the four main types of weight-loss surgery.
Roux-en-Y Gastric Bypass
During this procedure, the surgeon makes a small pouch at the top of your stomach. The pouch limits the part of the stomach that receives food and significantly limits the amount you can eat and drink at one sitting.
The small intestine cut just below the main stomach and connected to the pouch. Food flows from the pouch into the intestine. The main stomach continues making digestive juices. The rest of the intestine is re-attached to the main stomach to allow digestive juices to reach the small intestine. As a result, fewer nutrients and calories are absorbed.
Laparoscopic Adjustable Gastric Banding
During laparoscopic adjustable gastric banding, a band with an inflatable balloon binds the upper part of the stomach. This makes a small stomach pouch above the band with a narrow opening to the remainder of the stomach.
A port is positioned under the skin of your abdomen to connect a tube to the band. Fluid inside the balloon can be added or reduced through the port, the balloon can be inflated or deflated to adjust the size of the band. Gastric banding limits the amount of food that fits in your stomach, so you feel full sooner, but it doesn’t reduce the absorption of calories and nutrients.
A sleeve gastrectomy separates part of the stomach and removes it from your body. The rest of the stomach makes a tube-like sleeve that can’t hold very much food. It also produces less ghrelin, the hormone that makes you hungry. A sleeve gastrectomy doesn’t affect how many calories and nutrients your body absorbs.
Biliopancreatic Diversion with Duodenal Switch
The surgeon removes a large part of your stomach and closes off the middle section of the intestine, reattaching it to the shorter piece to the duodenum. This is the so-called duodenal switch. The separated intestine remains and continues to allow bile and pancreatic digestive juices to flow into this portion of your intestine. This is called the biliopancreatic diversion. These changes limit the absorption of nutrients and calories.
Your weight loss doctor Houston patients recommend will explain the likelihood of success for each type of operation in regards to your circumstances.
