A gastric bypass surgery allows food to bypass part of your intestine and makes your stomach much smaller. After the procedure, the amount of food you consume will be much lower, resulting in lower calory intake which leads to weight loss. You will feel like you are full much quicker than you did before you had the gastric bypass surgery. In a gastric bypass such as Roux-en-Y, stomach is made smaller with surgical staples or plastic bands creating a small pouch near the top of your stomach. This procedure is accomplished by a large incision in the abdomen. Gastric Bypass Surgery is not often used to treat obesity and many health professionals consider it for those who have trouble losing weight with other treatments and who are at risk for other complications. This surgery has risks such as: infection, leak from stomach into abdominal cavity, blood blockage therefore it is important to discuss with a doctor on treatment options. Most people after having the surgery begin to lose weight quickly and this continues up to 12 months. [Source: WebMD]
