Gastric bypass, also called Roux-en-Y gastric bypass surgery, is one of the most common types of bariatric surgery. Your stomach is stapled into two pieces, which speeds the flow of food into your intestine. The physical change also alters the gut hormones that influence feelings of hunger and fullness.

Gastric bypass is considered a “metabolic” procedure because it changes how your body absorbs fat, calories and nutrients. This metabolic change occurs because your gastrointestinal tract is altered when your gastric bypass surgeon attaches the smaller section of your stomach directly to your small intestine. As a result, your appetite changes and you feel full faster.
Minimally Invasive Gastric Bypass Surgery
Your surgeon may use different devices such as magnets or robotic surgery to reduce the number of incisions needed to perform gastric bypass. This minimally invasive surgery approach:
Overall Weight Loss Surgery Benefits
The long-term success of bariatric surgery depends on your ability to make permanent changes in your diet, behavior, and exercise. When those changes take place, studies show that people who undergo bariatric surgery:
Have reduced cardiovascular risk, less sleep apnea, and less joint-related pain
Enjoy improved quality of life
There are additional benefits specific to gastric bypass.
Expected Weight Loss for Gastric Bypass
The average person loses about 30 to 40% of their excess body weight in the first six months following surgery. Long-term, the average person keeps about 50% of their excess weight off in the 10 to 15 years after surgery.
You Feel Full, Faster
Because the gastric bypass procedure makes your stomach smaller and changes how your body processes food, you will eat less. It also reduces the amount of “hunger hormones” produced by your GI tract. As a result, your average meal will be much smaller, and you will feel fuller faster.
Relieves Acid Reflux and GERD Symptoms Studies show that gastric bypass is more effective at providing relief from heartburn, acid reflux, and other symptoms of GERD than gastric sleeve.
Gastric Bypass Is Reversible
Because we are not removing any portion of your stomach, it is possible to return your anatomy to normal.
Gastric bypass is a complex procedure that carries some health risks in addition to the risks associated with surgery in general, and weight loss surgery in particular.
Leaks may develop from your stomach and small intestine.
Internal Hernia, Blockages, Gallstones, and Narrowing (Strictures)
There are increased risks for these conditions where the stomach and intestine join. They may require additional surgeries.
Can occur in the GI tract. They are more common in people who smoke or take NSAIDs (nonsteroidal anti-inflammatory medications, including aspirin and ibuprofen) after surgery.

Related to how your body absorbs nutrients. This can lead to low levels of vitamins, iron, and calcium. A lifelong nutritional regimen overseen by our nutritionist addresses this concern.
Can occur because your shorter small intestine does not handle the processing of sugary and starchy foods. As a result, you may experience sweating, flushing, dizziness, abdominal pain, vomiting, and other unpleasant symptoms that typically last for 30-45 minutes. Some people report that they appreciate this unpleasant physical reminder to stay away from starchy, sugary foods.
May lead to abdominal pain but can be treated with a stool softener.
