There are some major problems that can happen. These don't happen very often, though. Your health may play a role in whether or not some of these problems happen. For example, people who have severe heart disease, diabetes, are overweight, use tobacco, have had other surgeries on their abdomen, or have kidney or lung disease have a higher chance of problems happening than those who are healthier. Your health may also be an important part of how well your body heals if any of these things happen.
