 What are the risks of obesity surgery?
A certain amount of risk exists with any operation, and the risk is increased with patients who have had previous surgery of the stomach. Wound infections can occur, leaks of the new pouch or at the sites of the intestinal connection are unlikely, but can happen. If a leak or obstruction develops, reoperation is usually necessary. Blood clots to the lungs can happen as with any operation, but are very rare. Our most frequent late complication (3%) is peptic ulceration. In order to prevent this complication you will be placed on antiulcer medication for a number of months after the surgery. You will also be instructed to avoid medications such as aspirin and some others used to control joint pain, menstrual cramps and inflammation (non-steroidal anti-inflammatory agents). It is good practice to check with the surgeon before starting any new medication.
Ulcers have a tendency to develop more frequently in smokers or people that use alcohol excessively.
The gastrointestinal absorption of iron is somewhat impaired as a result of this operation. We therefore recommend that all menstruating females take supplemental iron. In all patients it is mandatory to take a multivitamin supplement with minerals for life. Calcium intake should be increased. Nausea and vomiting can occur if food is eaten too quickly or not chewed well.
