Gastric bypass surgery is done mainly to treat morbid obesity and other co-existing conditions related to it. In simple words, this surgery will make the stomach smaller. The food will go around or bypass a small section of the small intestine. When this occurs, the patient who undergo gastric bypass will eat less since he or she feels full right away. Feeling satisfied will lessen food craving and thus would lessen the calories consumed by the body and eventually result to weight loss.

In fact, gastric bypass surgery is simply one of various similar surgical procedures done to treat obesity.  The collective term for all this kind of procedures is bariatric surgery.  These surgeries aim to lessen the buildup of fatty tissues by changing the physiological and psychological aspects of a patient regarding eating and food.

How does it change ordinary digestion?

What usually occurs is that after eating, the food would pass through the stomach and then go toward the small intestine. Absorption of nutrients happen in the small intestine before it goes toward the colon wherein the fecal matter is ultimately taken out of the body. The widely used gastric bypass surgery, the Roux-en-Y, changes this digestive process. For details see Types of Gastric Bypass Surgery.

In the Roux-en-Y, a small stomach pouch is created above the stomach. The bottom part of the stomach, which is much smaller in size now, is attached directly to the middle section of the small intestine. The stomach became smaller and all at once, the intestine was shorter, the upper part of the small intestine was bypassed. Both the above part of the stomach and the upper part of the small intestine no longer digest and absorb food and nutrients.

Studies revealed that patients would generally lose 60% of his or her excessive weight following the gastric bypass operation. There are even patients who undergo gastric bypass who would state that they have lost 80% of their excessive weight. There are statistics revealing that more or less 90% of patient who have undergone gastric bypass operation were able to keep their weight loss after 10 years of the gastric bypass operation.

However, undergoing gastric bypass procedure is not 100% safe. Patients who have undergone gastric bypass would have more cases of gallstones, in other statistics; they would also say they have nutritional deficiencies such as anemia or osteoporosis.

Each year there are more or less 140, 000 gastric bypass surgery being done in the US alone. The outcomes could really be positive, with patients being able to get more weight loss outcomes, but approximately 2% of patients would discover it life-threatening. In the 2%, 1% could be dead because of complications during surgery. The heart might not be able to handle the pumping it needs to do to cope with the extra weight or the complication caused by it.

The other 1% cause of death among patients who undergone gastric bypass surgery would be because of not following dietary limits that must be followed following the surgical procedure. Following gastric bypass operation, the body could no longer support excessive consumption of high-fat and high-sugar food. There will be a particular diet that those who have just undergone the surgical operation should obey. Gastric bypass diet would normally involve high-protein, low-fat, low-fiber, low-calorie and low-sugar foods. In addition, there are vitamins and mineral supplements that should be taken to prevent health problem and nutritional problems.
