<p>Just make sure you are not using it as an excuse to explain poor grades or test scores. I think I would probably recommend having your guidance counselor address a medical issue in his/her recommendation so that admissions can see you as more than just a med issue in your application. I am not sure what you are hoping a letter from a doctor will achieve in the admissions process. Of course, it also depends on what the condition is - if you want to PM privately, please do so. </p>
<p>In the meantime, any thoughts on revealing medical issues?</p>
