There are a number of possible major complications that can occur. These are very uncommon, however, your overall health will play a role in your likelihood of developing complications and how well you recover. For example, patients with severe heart disease, diabetes, serious gastrointestinal or lung disease have a higher chance of complications occurring than those who are healthier.

Depending on the individual situation, a major complication may lead to a hospital stay, or in very rare cases, surgery, permanent disability or even loss of life. Major complications occur in approximately 2 out of 1000 procedures, with loss of life occurring in 1 out of 10,000.
