Keyhole Gastric Bypass Limiting Absorption

Colorado rates for HCPCS 43645

A weight-loss operation done through small abdominal incisions with a camera, in which the stomach is made much smaller and the small intestine is rerouted so food bypasses a long stretch of it. Because food and digestive juices only meet near the end of the intestine, far fewer calories and nutrients are taken up. It combines a smaller stomach with deliberately reduced absorption.
