<p>What will be of interest to colleges is whether your health problems will impact your academic performance/involvement in college.
If the absences aren’t on your transcript, and haven’t impacted your academic performance as indicated by the grades on your transcript, then you’re good to go.
However, you need to get a handle on your health problems before you land on campus. In college, there is no difference between excused/unexcused absences–there are just absences. Many professors have an attendance policy and/or class participation policy (as in you don’t get points for participating if you are not present in class) and absences can have a huge detrimental effect on your grade. They really don’t care what your excuse for missing class might be–whether you have a migraine, or the flu, or a paper to complete for another class, or were out too late the night before–an absence is an absence.</p>
