About explaining an condition to professors...?

So, I've got a chronic malady (gastroparesis), and all my professors and the dean and adjectives know about it. I asked for an extension on a midterm exam that should've be today and my professor said that's fine. I haven't studied at all; I spent yesterday and adjectives weekend lying in bed doing nil.
So, my question - how much should I relay my professor? I hate asking for an extension on stuff approaching this, and I want him to know that I've really been sick, adequate so I would've been taking the oral exam cold. But maybe that's adjectives too much information... Anyway, I really appreciate any advice!About explaining an condition to professors...?
Yes, it is too much information. If they request a minute from your doctor, the doctor would only narrate them that you have be under that doctor's aid for an ongoing condition that has made you moderately ill. The doctor may put a date on the make a note of to re-evaluate you so you can return to your studies full time. You do NOT talk give or take a few what you have. Not requisite at all. The dean/professors a moment ago want to know you are legitimately sick. You are lucky. Most colleges will make you transport a semester off if you miss to copious classes/exams and reapply next semester.
The institution and (maybe even this particular professor) should enjoy a written policy on excused absences. Check the policy contained by the handbook or online, and see what is required - that's adjectives your need to do unless you are going to perceive guilty without explaining to your professor that the malingering was really lawful.
