That seems strange, although depending on how tall she was weight diffentials get pretty small. Like if you are 5'5 or below the difference between obese and normal is under 25 pounds (small window for overweight) It's only 40 pounds at 6'5. People are always built differently though so it's weird. When I was in my best shape I was always considered overweight according to the BMI chart because I was between 5'10/5'11 and was always around 187 pounds. No doctor would have called me fat at that time because I ran 5-10 miles a day and could dunk a basketball with both hands, I was lean but density was just high. I don't know anything about surgeries but I would figure they have to do with blood pressure and clotting habits maybe? The doctor likely was just an ass, hopefully her hand healed up well. Pain in the ass medical field we have here.
