RNY Gastric Bypass is the most common type of Weight loss surgery performed in the United States today
.
RNY Gastric Bypass is considered by Duke university Medical Center to be the " Gold Standard" of all weight loss surgeries.
RNY Gastric Bypass works because the size of the stomach is reduced to around the size of an egg.   At the same time the surgeon will bypass a portion of the small intestine so your body cannot absorb as much of the nutrients that pass through it.
The above features make the surgery a very powerful tool for the morbidly obese patient to use to lose weight and keep it off.
