If you are struggling with obesity or excess weight and have tried dieting and exercise to no avail, surgery may help you attain a healthy weight. Bariatric surgery refers to a procedure that alters your digestive system to help you lose weight. It works in two ways: restriction and malabsorption. In restriction procedures, the surgeon reduces your stomach size so you can feel full by eating less, while malabsorption lowers the number of calories you absorb. Read on to find out the various forms of bariatric surgery that can help you shed excess weight.
What are the Types of Bariatric Surgery?
Bariatric surgery uses various methods, and the option you choose depends on your age, health, and preference. Your surgeon will take you through the available options and help you make an informed decision. Types of bariatric surgery include:
Roux-en-Y Gastric Bypass
Roux-en-Y gastric bypass
is the most popular type of bariatric surgery. It involves creating a small pouch in your upper stomach and connecting it directly to the small intestine. The remaining part of your stomach is then connected to the other end of the small intestine further down so that it continues producing enzymes and acid for digestion.
With the reduction of stomach size, you automatically eat less. Roux-en-Y also promotes malabsorption as the re-routed intestine bypasses most of your stomach and parts of your small intestine. Roux-en-Y typically offers higher and faster average weight loss compared to sleeve gastrectomy and adjustable gastric band. It can also improve certain health conditions, such as type two diabetes and hypertension.
Just like gastric bypass, sleeve gastrectomy reduces the size of your stomach. However, in sleeve gastrectomy, your surgeon removes 80% of your stomach permanently and sews the remaining part to form a sleeve-like pouch. The procedure is minimally invasive and permanent.
Apart from reducing your food portions, sleeve gastrectomy reduces the amount of ghrelin, a hormone responsible for hunger. By sticking to the recommended diet and exercise, you can lose up to 50% of your excess weight in as little as 18 months.
During a duodenal switch procedure, your surgeon removes 80% of your stomach and reroutes your small intestine by bypassing a small portion of it. The first part of your small intestines is divided into two, and one section, known as the alimentary limb, is connected to the stomach pouch.
The second part, known as the biliopancreatic limb, separates the digestive juices produced by the pancreases and gallbladder until the sections meet at a common channel. A duodenal switch works by reducing the amount of food you need to be full as well as the number of calories your body absorbs.
Some of the benefits of a duodenal switch include:
- It results in weight loss of up to 70%
- You eventually get to eat normal-sized meals
- No food restrictions
Duodenal Jejunal Bypass with Sleeve Gastrectomy
This is a modified version of the duodenal switch. Your surgeon removes 80% of your stomach to create a sleeve and reroutes the lower part of your small intestines. The small intestine is divided just before the entry point of digestive juices into the digestive tract.
The lower part of the small intestines is also divided into two and connected to the duodenum to create an alimentary limb. This procedure minimizes malnutrition from a duodenal switch. It also results in more weight loss compared to gastric bypass.
Revisional surgery is the conversion or repair of earlier bariatric surgery. For example, your doctor may change sleeve gastrectomy or adjust the size of connection in a gastric bypass. If you start gaining weight after bariatric surgery, you will require revisional surgery to correct it.
Revisional surgery gives you the chance to lose weight that you may have gained after an earlier bariatric surgery. It is also an opportunity to correct an earlier bariatric surgery that failed to give the desired results.
Laparoscopic Adjustable Gastric Banding
This type of bariatric surgery involves placing a silicone elastic band around the upper part of your stomach to create two compartments. When you eat, the food goes into the first compartment, which is smaller. Afterward, the food slowly goes through the band's opening into the larger section for normal digestion.
The band attaches to a balloon and connects to a port under the skin on your abdomen. Your doctor can inject a saline fluid through the port into the tubing to tighten the band or withdraw fluid to loosen it. Constricting the band causes you to eat less as it decreases hunger by slowing the passage of food into the second part of the stomach.
This procedure is reversible, minimally invasive, and does not cause nutritional deficiency. You can also adjust the band without requiring surgery.
