Roux-en-Y gastric bypass surgery reduces the size of your stomach and changes the route of your intestines, limiting the amount of food you eat and calories you absorb.
This surgery requires lifelong changes in your eating habits and your attitude about food. Every day you will need to make good food and exercise choices. Thousands of patients have succeeded with this program. With your full commitment and the support of family and friends, you can too.
Roux-en-Y gastric bypass surgery changes the size of your stomach and your ability to absorb calories to help you succeed at long-term weight loss. This surgery cuts down the amount of food and liquid you can hold at one time. Your stomach will hold about 1 to 2 tablespoons of food at the beginning. As you fill up, a signal is sent to your brain that you feel "satisfied" and should stop eating. If you try to eat too much or too quickly, you may feel a wave of nausea or abdominal pain, or you may vomit.
This surgery does carry risks. Possible complications include infection, bleeding, anesthesia risks, hernia, leaks, blood clots and ulcers. Also, the outlet at the bottom of the stomach may get plugged (clogged), or your body might not absorb some vitamins and minerals you need. Death from weight-loss surgery is a risk, but it is not common. This risk is about the same as that for gallbladder surgery or hip replacement.Back to top
