My brother had gastric bypass surgery almost 7 months ago. As he healed he had scar tissue that pinched off the opening for secretions to drain from the old stomach. They put in a drain until the swelling goes down and they can do the surgery to fix the problem. Now he's having a problem in that his heart rate is never under 100, and he gets dizzy and he's very shaky ? Any help or advice you can offer would be much appreciated! Thanks, Concerned Sister
