Types of Weight Loss Surgery




Types of Weight Loss Surgery

There are many reasons why some people become so obese that they have to turn to weight loss surgery. Some have genetic factors which sees them putting on weight much easier than others while other people may have an injury which prevents them from exercising to lose weight.
For some people dieting will only help them to achieve so much and the need to exercise is vital to losing weight. But for those too heavy to exercise weight loss surgery can become their only option. There are various types of weight loss surgery available.

Lap band surgery is where an inflatable band is placed around the stomach to divide it into two sections with the smallest section being at the top. Food is limited to the amount the smaller section can hold and a small gap between the two sections allows food to travel between them at a very slow rate. Once the food gets to the larger part of the stomach it is digested as normal. The fact that it can take such a long time for the food to get to the larger part of the stomach means that you will feel full for much longer. The band is adjustable. It can be made tighter by injecting saline into it or looser by taking some of the saline away. This type of weight loss surgery is usually only available to people who are more than 100 pounds overweight.

Vertical banded gastroplasty is a procedure where the stomach is separated into two by staples. It is similar to a lap band surgical procedure in that the stomach is split into a small section and a large section with a small gap between them for food to pass through slowly. A band is placed around the gap to prevent it from enlarging. This procedure will also reduce the amount of food that the patient can eat.

Biliopancreatic diversion involves removing a part of the stomach and connecting the remaining part to the bottom of the small intestine. It means that food will be passed directly to the end of the small intestine where the food is digested and mixed with bile etc. This form of weight loss surgery is most infrequently used as it can lead to deficiency in essential nutrients.

A Roux-en Y gastric bypass will split the stomach into two with staples. The smaller section is then connected to the middle part of the smaller intestine and will see food travelling directly to the small intestine. It can increase the amount of time that food takes to travel through the small intestine resulting in less calories and nutrients being absorbed by the body. This can obviously lead to patients becoming nutritionally deficient.

A vertical sleeve gastrectomy is the most difficult procedure to perform and only 15 surgeons worldwide can perform it. It involves the stomach being split in two vertically and the largest part removed permanently.

Of the various types of weight loss surgery, some are more common than others and all have pros and cons. A doctor will discuss the best option for each individual.
