I'm confused I"m 63 1/2 inches tall and at last weigh in at surgeons office 261.8. When I calculate my BMI I get 46 something they get 44 something which is correct?

According to the National Institue of Health's BMI calculator, with a height of 5'3.5" and a weight of 261.8, your BMI is 45.6. I like this calculator because it's easy to use. Just plug in your info and hit calculate.

It is likely they adjusted your weight down to allow for clothing.  No worries ... its all good.
