What are the pros of gastric bypass surgery?

ANSWER

The Pros:

  • Weight loss is quick and dramatic. People lose an average of 60% to 80% of their excess body weight.
  • Because weight loss is quick, weight-related health problems such as diabetes, high blood pressure, high cholesterol, arthritis, sleep apnea, and heartburn improve quickly.
  • Most people are able to keep at least 50% of the excess weight off long term.
  • Loss of stomach tissue results in a drop in the so-called "hunger hormone" (ghrelin), which helps control appetite.
