The trade-off of having a weight loss procedure of any type is the complications associated with it. The incidence of death from the operation itself is approximately 1% or less, and 25-30% of patients will develop some form of complication after the operation. Fortunately, most of these complications are minor, consisting of wound infections, respiratory problems, hernias in the incision and vomiting.
Complications of gastric bypass:
The long-term complications of this operation are related to vitamins and minerals. Approximately 50-60% of patients will develop iron deficiency, 75% will develop low vitamin B-12 levels and 40% will develop low folate levels. These deficiencies, either alone or in combination, result in a 30-40% incidence of anemia which can be serious at times. In order to correct for these problems, patients are supplemented with daily iron, multivitamins, B-12 and folate pills. The addition of these vitamins and minerals eliminate these complications for the most part.
