A combination restrictive and malabsorptive procedure in which a small stomach pouch is created then attached to a portion of the small intestine. Having the small pouch causes you to eat less food and bypassing a portion of the intestine means the body absorbs fewer calories and nutrients.
- More invasive
- Have to take vitamins and minerals the rest of life
- Higher risk for trauma and side effects
- Can have dumping syndrome (rapid movement of food through small intestine that leaves the patient feeling flushed and uncomfortable).
