Hello I have had CAH since I was born and now I'm 17.  My medication has increased, but during sports I normally don't have to change my medication.  The only times I raised my med. dosages is when I went into surgery or very sick with the flu.  When I did played sports, I drank tons of water and normally would take a salt tablet and I was great.  I also had gatorade next to my water to get electrolytes in my body.  Just to let you know I was in softball, soccer, tennis and golf most of my life until this year (don't have enough time).

Hope this helps,

Christina
