What are the potential risks?

Any type of surgery carries a higher risk in a person who is overweight. There have been only a few serious complications in over 16 years of our GBP experience. Some of the risks are: wound infections, blood clots in the legs or lungs, pneumonia, loss of spleen, stomal ulcer, stomach leakage of peritonitis, abscess and fistula formation, wound hernia, dehiscence, stomal stricture, excess bleeding, and staple line failure (see part II, page 2). Any of these complications can and have been life-threatening, but morality is rare with this type of surgery. Some patients also suffer from temporary hair loss, but this usually stops within 6-10 months.
