The procedure helps patients lose weight by reducing the amount of food you are able to eat and therefore, absorbed by the body. Due to the fact that there is only a small bag of stomach left, patient can eat small amounts of food and feel full.
Gastric bypass surgery consists of two stages, first: the stomach is divided very close to the upper part, leaving a small bag the size of an egg. Then, the small intestine is divided and reconnected with the thick intestine. One side of the small intestine is sutured to the stomach. After the bypass surgery, food enters through the esophagus towards a small gastric bag and then passes directly to the digestive juices.
The gastric bypass cannot be performed laparoscopically with all patients, especially in those that have high body mass index or extensive abdominal surgery.
- Efforts to lose weight with diet and exercise have not been successful
- Your body mass index is 40 or over (extreme obesity)
- Your body mass index is 35 to 39,9 (obesity) and you have health problems related with weight, like type 2 diabetes, high blood pressure or severe sleep apnea. In some cases, you can qualify for certain types of surgery to lose weight if your body mass index is from 30 to 34 and have significant health problems related to weight.
Most patients recover from surgery without complications. Patients are asked to start walking the next day after surgery to prevent liquid accumulation, avoid cloth formation or infection. The stay in the clinic for patients that undergo a gastric bypass surgery, is usually of two to three days. Most patients resume their work activities after 2 or 3 weeks.
