All over the world, weight loss efforts continue to take new measures day by day. People from all walks of life have tried almost everything, ranging from daily scheduled exercises to a strictly administered diet but still the battle has not fully been won. It is for this reason that technological innovations like gastric bypass and gastric band have found a place in the field of body weight loss.
Gastric bypass is surgical procedure. It controls food flow between the stomach and small intestine. As its name suggests, a bypass is improvised. Firstly, the surgeon divides the stomach into two unequal chambers; the lower and the upper. The upper portion of the stomach is made small, leaving the lower one large. After dividing the stomach and ensuring that the smaller part of the stomach is as small as possible that it can only hold approximately a cup of food, the surgeon staples that part. He further goes ahead and introduces a bypass which overlooks the duodenum by connecting the jejunum directly from the smaller portion of the stomach. As seen, the procedure aims at reducing the quantity of food consumed by the patient. By cutting down the amount of food consumed, the body of the patient is exposed to fewer calories. This prompts the body to burn the excess fat which is stored under the skin thus reducing the body weight. Once the excess weight has been offloaded, the new weight is maintained by availability of fewer calories.
Gastric band also aims at the same thing of reducing the food quantity reaching the small intestine but it differs slightly on the principle it uses to achieve this goal. A silicone band is used. This band is used to divide the stomach into two parts. The band, which is adjustable, is placed round on the...

...urgeon is not optional. Under directions of the surgeon, the patient may undergo other tests before the operation. As is the case with many other stomach operations, medical fasting is exercised before the operation.
After the operation, the patient may remain in hospital for a short period. This is in aid of helping the patient adapt to the new eating habits. A diet of mashed foods is recommended for a period not exceeding three weeks. Thereafter, the patient can adapt to soft foods gradually. Any complication arising should be reported promptly.
Gastric bypass and gastric band are termed successful if the excess weight hits the 50% mark below its original value and if this situation is maintained for plus five year. Tests show that on average, 50% weight loss is achievable within the first two years since the operation. They are reliable methods of weight loss.
