Gastric bypass side effects shouldn't wait to be discussed until after surgery, these should play a major part in your decision whether or not to have the surgery.

Nausea is the first of the many gastric bypass side effects. Usually this is caused by other side effects like food intolerance. Because you have a different stomach size, you will not be able to tolerate fatty foods or foods with a difficult texture to digest. And eating these foods can lead to nausea.

You might also notice a change in your bowel habits. Because you have radically changes your eating habits, this isn't too much of a surprise. Your fiber intake may have decreased and this will lead to less bowel movements.

As spoken of before, one of the gastric bypass side effects for patients is hair loss. Because of the drastic change in the nutrient levels in the body, this is why this occurs. Along the same lines is a possibility of muscle loss from less food to support them.

But even those these gastric bypass side effects seem outrageous, they actually diminish as your body finds a way to deal with the new body and digestive system that is has. Hair grows back, muscles replenish, and you learn to eat differently. In your new body.
