Surgery to treat severe obesity is expanding at a very fast rate, and quite rightly. Although gastrointestinal surgery is a last resort, it is proven that is the only technique to lose too much weight and stay so. Worldwide obesity is becoming already an epidemic, a health problem that affects all areas of the life of those who suffer from it. It is a condition that is expanding too quickly, due to various factors. Inheritance can be a cause, but the sedentary lifestyle, little or no exercise, and excessive calorie intake, in addition to the pace of life as you have, they seem to be the main causes of overweight and obesity.

Although there are several alternatives for weight loss, bariatric surgery is the only one who has tried to help the patient to lose too much weight and kept so. This can be a good thing for the super obese patients, but for medicine and science, is a failure to try to find alternatives or less drastic solutions to combat the growing health problem that is obesity. There are two main types of surgery to treat obesity. One of them is the lap band, where the placement of an adjustable band creates a small pouch in the stomach, thereby limiting the amount of food that you can eat every time. The other technique combines stomach restriction and cut part of the small intestine to reduce the area that absorbs calories and nutrients. Both procedures manage the patient to lose weight, but this combined approach is much more effective than the other.

The combination of the restrictive and poorly absorbent has proven to be more effective at producing long-term weight loss. If patients eat much or too fast, feel discomfort immediately. Patients have been performed the gastric bypass operation, usually lose a lot of weight the first two years, then rise a bit and stabilize later.
