When considering weight loss surgery, it is essential to investigate the various methods of weight loss surgery to find out which one is right for you. A health care professional will in addition guide you through your selection process to find the procedure that will provide you with the most success when striving to lose the excess weight.

There are three forms of weight loss surgeries that are routinely preformed. Each category has both benefits and disadvantages. Hospitals often use either a restrictive, malabsorptive or a combination of the two when performing weight loss surgery. Malabsorptive surgery is one procedure that is frequently performed. This form of surgery employs surgical methods to short the digestive tract. This makes it possible for the body to limit the number of calories that a person can absorb. The biggest disadvantage of this category of weight loss surgery is that is also limits the amount of essential nutrients taken in by the body.

The Biliopancreatic Diversion is the most important type of malabsorptive weight loss surgery that is performed by surgeons. This method is often more extreme because it requires a complete modification of the digestive system. During this weight loss surgery, roughly three-fourths of the stomach is completely removed. The remaining stomach pouch is afterward linked to the final section of the small intestines. This causes the food to almost completely bypass the small intestines and food enters the large intestines much quicker. After food is swallowed, it passes from the new stomach pouch to the remaining small intestines. There, the nutrients are separated from the bile and pancreatic fluid that normally breaks them down. This method vastly reduces the amount of both calories and nutrients that are absorbed by the body.

While highly invasive, there are some benefits. First, this operation allows for the greatest amount of initial weight loss due to the extents of absorption. Also, this weight loss surgery allows for larger meals because the stomach pouch is larger. With this operation, there will in most instances be higher total weight loss. Many times this surgery is reserved for those with much more weight to lose.

There are many disadvantages to this weight loss surgery. It is very invasive and requires more cutting and stapling of the stomach and bowel. With this come a higher rate of postoperative obstacles, and fatality. It also takes longer time to heal from this surgery than with other methods. Patients are not able to return to ordinary activities for several weeks following this form of surgery. Patients that have this surgery are subject to suffering from ulcers, intestinal irritation and dumping, which is caused by the food passing very promptly into the intestines. This can cause diarrhea, stomach cramping and nausea. This surgery is not reversible and cannot be adjusted for any reason. Also, patients also must have life-long monitoring for protein malnutrition, anemia and bone disease. Most patients that have this form of weight loss surgery must stay on vitamin supplements for the rest of their lives to make up for the reduced amount of nutrients absorbed into the body.
