Post Gastric Bypass Surgery CT Scan

I saw this piece they did on the news about how 1/3 of gastric bypass surgery patients are too obese to fit into the CT machines to check for problems post surgery. It made me kinda mad because they kept making it sound like the gastric bypass surgery caused this problem! That is something that is talked about before the surgery and is a part of it, as far as the weight, they would not be having the surgery if they did not need to desperately lose weight!
