What are the dangers of gastric bypass surgery?

The dangers of gastric bypass surgery are mainly due to the fact that it is a major operation. As with any surgery, there is always a risk of complications such as infection, blood clots, and even death.

There is also the risk that the patient will not lose weight after surgery. In some cases, people have actually gained weight after having gastric bypass surgery. And finally, there is the risk that the patient will develop nutritional deficiencies after surgery. This can occur if they do not follow their doctor's instructions about what foods to eat and what supplements to take.
