Document Summary
It was a difficult decision but sheila decided that the benefits of bariatric surgery outweighed the risk. The surgery itself went well and, in the past year, sheila and has been able to lose 45 kg (100 pounds). The changes in sheila"s gi tract have caused some problems, though. First, she must carefully limit what and how much she eats, because alterations in her stomach have bypassed the pyloric sphincter, which regulates the rate at which material leaves her stomach. When she eats too much or chooses too many high-carbohydrate foods, her meal dumps into her intestines and draws in water, resulting in dizziness, sweating, and diarrhea. Second, her small intestine has less surface area for nutrient absorption now that a portion of it has been bypassed. To prevent vitamin and mineral deficiencies, sheila must take supplements and get monthly vitamin b injections.
