Gastric Bypass is one of the most frequently performed procedures for morbid obesity in the U.S., and has shown to be significant in the resolution of type II diabetes. A gastric bypass restricts food intake and the amount of calories and nutrients the body absorbs. In this procedure, the surgeon creates a small stomach pouch and attaches a section of the small intestine directly to the pouch. This allows food to bypass a portion of the small intestine. Having a smaller stomach pouch causes you to feel full sooner and eat less; bypassing part of the small intestine means the body absorbs fewer calories.

- Overall quality of life improved greatly.
- They experienced improved physical functioning and appearance.

Potential Concerns of Gastric Bypass
A condition known as dumping syndrome can occur from eating high-fat, high-sugar foods. While it isn’t considered a health risk, the results can be very unpleasant and may include nausea, weakness, sweating, faintness, palpitations, and diarrhea. Dumping syndrome can be prevented by avoiding high-fat, high-sugar foods. Patients must supplement their diet with a daily multivitamin, calcium, vitamin B12, and iron.
