Weight loss (Bariatric) surgery helps you lose weight and reduce the risk of health problems related to obesity. Bariatric Surgery allows you to lose weight in two ways:
Restriction. Surgery is used to physically limit the amount of food the stomach can contain, which limits the number of calories that you eat.
Malabsorption. Surgery is used to shorten or part of the small intestine which reduces the amount of calories and nutrients the body absorbs workaround.
Four types of Bariatric Surgery are:
- Roux-Y gastric bypass
- Laparoscopic adjustable gastric bands
- Biliopancreatic with duodenal switch bypass
Roux-Y gastric bypass
A gastric bypass Roux-Y, the surgeon creates a small pouch at the top of the stomach. The bag is the only part of the stomach that receives food. Which considerably limits the amount you can comfortably eat and drink both.
The small intestine is then cut away below the stomach and connected to the bossa nova. Food flows directly from the pocket of this part of the small intestine. The main part of the stomach, however, continues to make the digestive juices. The part of the small intestine is still attached to the stomach is back in place below. This allows the digestive juices flow to the intestine. To eat now part of railroad bypass of the small intestine, they absorb less nutrients and calories.
Laparoscopic adjustable gastric bands
Laparoscopic gastric adjustable bands in the procedure, a group that includes an inflatable balloon is placed at the top of the stomach, which is fixed in place. This creates a small stomach pouch on the side with a very narrow opening to the rest of the stomach.
A port is placed under the skin of the abdomen. A pipe connects the port to the band. Injection or by removing the fluid through the port, the balloon can be inflated or deflated to fit the size of the band. Gastric Fluorocroms restrict the amount of food that can hold your stomach, because you feel full before, but don’t reduce the absorption of calories and nutrients.
In a manga of gastrectomia, part of the stomach is separated and removed from the body. the remaining part of the stomach is formed in a tabular structure. This small stomach cannot hold as much food. It produces less appetite suppressant hormone ghrelin, which can decrease your urge to eat. Gastrectomy, however, does not affect the absorption of calories and nutrients in the intestine.
Biliopancreatic with duodenal switch bypass
As with gastrectomy, this procedure begins with the surgeon has removed a large part of the stomach. The valve which releases food into the small intestine is, with the first part of the small intestine called the duodenum.
The surgeon then closed a middle section of intestine hail and paste the last part directly into the duodenum. It is the duodenal switch.
The separate section of the small intestine is not removed from the body. on the other hand, it is attached to the end of the small intestine, allowing bile and pancreatic digestive juices flowing in this part of the intestine hail. It’s the biliopancreatic diversion.
As a result of these changes, food bypasses much of the small intestine, limit the absorption of calories and nutrients. This, along with the small size of the stomach, leading to weight loss.
