What is the likelihood of death and complications from me getting gastric bypass surgery?

Every operation: Has potential risks versus potential benefits. Your surgeon goes through a complex decision tree whenever he sees a patient for possible surgery. If your potential risks outweigh the potential benefits, he will not perform any operation. Go see a surgeon, he can figure it out for you.

Depends: You must be obese to consider. Other risks include smoking, hypertension, sedentary status, mental health, attitude, compliance with instructions and meds.
