How a laparoscopic gastric bypass helps you lose weight

The gastric bypass works by creating a new, smaller stomach pouch and bypassing a section of your small intestine. This new smaller stomach can only hold a small amount of food: you feel full sooner, so you eat less. Meanwhile a reduced intestine absorbs fewer calories and nutrients.

How much weight will you lose
Gastric Bypass surgery usually offers a more dramatic initial weight loss than other procedures. More importantly, studies suggest that gastric bypass surgery is the most effective surgical treatment for maintaining long term weight loss.

You do still need to develop and maintain good eating habits if you don't want to regain weight over time. None the less, studies have demonstrated that on average, patients undergoing gastric bypass maintain a weight loss of 50 to 60% of their excess weight after 5 or 6 yrs and one study demonstrated an average of 50% at 14 yrs.

A gastric bypass really can be a lifetime solution to obesity.
