Weight loss surgery is basically meant to help people lose weight who are extremely obese and have failed to do so with diet and exercise. Another reason as to why they should be doing so is that there are many serious health problems associated with obesity. Moreover, bariatric surgery benefits in these cases far outweigh the risks which are normally involved with obesity as such. There are many types of weight loss surgery procedures, but they are generally based upon two main approaches. These are restrictive and malabsorption techniques. Restrictive weight loss surgery procedures physically limit the amount of food a person can hold and thereby limiting the number of calories which a patient can absorb. Malabsorptive weight loss surgery usually shortens or bypasses a portion of small intestine in order to restrict the amount of nutrients and calories which the body can absorb.
Most Common Types of Weight Loss Surgery
- Gastric Bypass Surgery – This type of obesity surgery will create a small pouch in the top portion of the patient’s stomach which will be the only place to receive food. It limits the amount of food which a person can ingest at one time. Along with this, the small intestine is also cut short below the main stomach and is connected with the new pouch. Food will now directly flow from the pouch to the intestine while the portion of the main stomach is reattached farther down in order to deliver the digestive juices. Since the food is now bypassing a part of the small intestine, the patient will be able to absorb fewer calories and nutrients.
- Adjustable Gastric Banding – This is a laparoscopic procedure which involves placing a band containing an inflatable balloon around the upper part of the stomach. Designed to create a small pouch above the band along with a narrow opening to the rest of stomach. There is a port which is placed under the skin of the abdomen which is connected to the band through a tube. With help of this device the balloon can be inflated or deflated by injecting or removing fluid through the port. Adjustable gastric banding is meant to restrict the amount of food which stomach can hold so that the patient feels full sooner.
- Sleeve Gastrectomy – Portion of the stomach is removed from the body in the sleeve gastrectomy weight loss surgery. The remaining portion is formed as a tubular structure which is much smaller and therefore will hold less food. With help of this the stomach will now also produce less quantity of appetite-regulating hormone called ghrelin. While sleeve gastrectomy will not limit absorption of nutrients and calories, it will effectively lessen the person’s desire to eat.
- Duodenal Switch with Biliopancreatic Diversion – This weight loss surgery also involves resizing the stomach. However, duodenal switch with biliopancreatic diversion retains the valve of the stomach which releases food to the small intestine and only removes other parts of the stomach. Subsequently, the surgeon will shut off the middle section of the small intestine and attach the duodenum to the end of the intestine so as to allow bile and pancreatic juice to mix with food in this part of the intestine. This is known as the biliopancreatic diversion. This bariatric surgery is very effective as the patient will now will absorb less nutrients and calories along with the smaller size of the stomach which also will limit consumption of food as well.
