### input:
I am a 21 yo NCAA cross country runner and within the past 2-3 years, I have been blanking out during races. I get blurry vision and headaches for about 15min after hard workouts/races and become very lethargic for the rest of the day even after eating and drinking water. The ATs thought it was hypoglycemia so I ve been eating carbohydrates before races and intense workouts (which never do anything and I still have the same symptoms). I ve been checking my sugar after races/workouts and it is around 200-250 mg/dL. Coaches also assumed my fatigue may have been from anemia. Ferritin level was 15 and I have been taking iron and vitamin C everyday for 3 months. My fasting glucose is usually around 105-120mg/dL. Is there a possibility I might have type 1 diabetes?

### output:

Diabetes doesn't seem likely with those sugar numbers.  When your symptoms come on do you feel LIGHTHEADED at all, faint, or otherwise zoned?  Are you usually breaking a pretty good sweat when this all happens?  Are you cutting weight for your running?  Have they taken your orthostatic blood pressures?  Have they measured your BP's orthostatically when you feel this way?  Have you had blood work done, imaging study of the head, EKG, or a Holder monitor?  I am a neurologist and I also compete as well as assistant coach a varsity NCAA wrestling team here in Cleveland, OH, so I know a lot of these sorts of issues as related to our guys and every year at least 1 or 2 of them get into similar problems.  Of course, wrestling is a different sport from track and weight losses play a major role in our sport that can get people in trouble if they're not careful.  But across the board, HY Chat Doctor. You say you're anemic?  And you're taking iron?  But have they also checked magnesium levels?  If you have a magnesium level deficiency, and you are anemic...no matter how much iron you take you will never correct the anemia.....so little details like that keep people from getting better.  Of course, a bigger question for me is WHY ARE YOU ANEMIC?  You shouldn't be....you're an athlete, your diet should be top-notch, your sleep habits should be top-notch, and your training should be intensive but controlled and carefully overseen.  You should HY
