Weight loss surgery or bariatric surgery has a big impact regarding weight loss. The surgery will help you in avoiding obesity because the surgery works in two main ways:
1.The surgery will limit the number of food you can eat physically. This will limit the amount of calories that entered your body
2. The surgery is used to reduce the absorption of nutrients and calories by shorten the small intestine.
Here are the 4 types of weight loss surgery.
Roux-en-Y gastric bypass
The roux-en-y gastric bypass will block your digestive system that can receive food. The surgeon will create a small pouch at the top of your stomach so that only the pouch will receive the food. This surgery greatly limits the amount of foods and drinks you could take at a time.
The new pouch will be connected to the small intestine, just below the stomach. The flood will flow through this newly made pouch and then straight to the intestine. Although the new pouch is there, the main part of the stomach will continue to produce digestive juices. A portion of the intestine is still attached to this main part so the juices can flow through the intestine and you will have a normal digestive system but with reduced amount of foods you can take. The foods bypass only a part of the intestine, making nutrients and calories absorbed by the body are fewer.
Laparoscopic adjustable gastric banding
Laparoscopic adjustable gastric banding is a surgery where the surgeon will put a band containing an inflatable balloon. The balloon then placed in the upper part of the stomach and then fixed so it won’t move around your stomach. The result is that there will be a small stomach pouch just above the band. There will be a narrow opening caused by this surgery to the rest of the stomach.
The next step is placing a port under the skin of the abdomen. The band then connected with this port with some kind of tube. The balloon can be inflated or deflated to adjust the size of the band based on how much fluid injected or removed through the port. It will not reduce the absorbing process and the nutrients won’t be affected, but you will feel full sooner because the surgery restricts the amount of food you can take.
Sleeve gastrectomy will have your part of the stomach separated and removed from the body. A tube like structure then formed from the remaining section of the stomach. This will cause your stomach have less capacity of foods. A hormone named ghrelin is affected, causing you to have less appetite. This surgery is not affect the absorption of nutrients and calories.
Biliopancreatic diversion with duodenal switch
This procedure will remove a large part of the stomach. The valve that allows foods to run through intestine is left, along with the duodenum or the first part of the small intestine. The duodenal switch will be made when the surgeon clos the middle of the intestine, making it directly through duodenum.
The removed part of the intestine isn’t removed from the body, but it is used at the end of the intestine to make digestive juices from bile and pancreas flow through this part of intestine. This is the procedure of biliopancreatic diversion.
The result of this is the foods will bypass most of the intestine and limits the number of nutrients and calories absorbed. The smaller size of the stomach will also help to reduce weight.
Those 4 surgery are needed if you want to have a weight loss. You need to pay attention to the food you are going to eat since weight loss surgery have an effect towards the size of your stomach and the number of nutrients you will get from foods.
