A member asked:

When i was in my last year of high school, i went from 140lbs to 240lbs in ~18 months. dark scaly spots appeared under my arms. what is wrong?

A doctor has provided 1 answer

See below: The dark scaly spots could be a rash known as acanthosis nigrans which can be seen diabetes, but without seeing it, it is difficult to say. Considering your weight gain and this rash, you may want to see your doctor to be screened for diabetes.
