<p>I finished high school this year, and opted for a gap year, because I was unsure as to whether I'd be fit to go to university because of ill health. The illness persisted throughout my final high school year, and I believe it greatly effected my grades.</p>
<p>I presume the best place to put this is at the end of the Common App and simply explain what happened. It's not my intention to seek sympathy, not at all, I just want to explain a question admissions officers may have.</p>
<p>On the other hand, would it be detrimental to my application, as in, will they not want to take the risk? Could insurance and whatnot be compromised (from what I understand, you can't get health cover with a pre-existing condition?). What I have is Crohn's disease, very mild, but it did leave me exhausted for much of this year. As around 1 in 1000 have it, I presume the universities would be aware of the condition, as statistically, some of the students and maybe even staff must have it too.</p>
<p>Has anyone had any experience of this? What are your opinions?</p>
