I have a friend applying in the match this year to some competitive specialties who has recently been diagnosed as hypothyroid. He had been feeling tired, gaining some weight, and feeling generally worn out for the past year. In fact he thought he was getting burnt out. This affected his academic performance and board scores. Since being diagnosed, he started replacement therapy and feels his old self again: for the first 2 years of med school he aced all the subjects etc.
The question is: should he notify programs he's already applied to about the cause of his recent performance?
Some of you will question the timing, but he's applying to Canada where they haven't given out interviews yet.
Thanks
