Question: Marathon Training

 jaobryan - Sun Sep 09, 2007 5:11 pm

I am a 39 year old woman and have been training for the Chicago Marathon. Recently, I have been trying to pass out. I get dizzy, feel faint, heart racing, hands numb and get shaky. I have not passed out yet, but sometimes I come very close. I also have noticed that when I get this way, I feel as if the blood has completely drained from my head. I had a physical prior to beginning to train and everything was perfect. No cholestrol problems, bp was fine, no heart problems and was not overwieght. I am in perfect health. I have lost about 15 pounds in the process but am still at a very healthy weight. Could this be low blood sugar, overtraining, fatigue or anxiety due to the impending race? Thanks for the advise.

User avatar Hi Jaobryan,

Low blood sugar, anxiety, and fatigue can all cause episodes of fainting feelings. I would recommend you see your doctor for an evaluation to be sure nothing dangerous is going on.

Best wishes.
