Gastric bypass surgery will result in long-term weight loss. The amount of the weight a person loss will be depends on which type of weight-loss surgery & the changes a person make in their lifestyle habits. It is possible to lose half, or even half of the weight, of the excess body weight within 2 years. The gastric bypass diet may help to recover from the surgery & transition to a way of eating which is healthy & supports weight-loss goals.

Once patient awake after the surgery, they will have a drip in their arm, to provide body with liquids, & may have a tube in the bladder, called as a urinary catheter, to drain urine out of the bladder. These tubes will be removed once patient was well enough to get out of bed. Again, patient will be given blood-thinning medication & compression stockings to wear and help to prevent from the blood clots. Patient needs to consume only a liquid diet immediately after the surgery & solids will be given slowly into their diet.

Start walking as much as they can after the surgery. Patient will be recommended to take clear liquid diet in the first week after the surgery. Most of the people are well enough to leave the hospital 1 - 4 days after the surgery & resume to their normal activities within 3 - 5 weeks.
