Well, the explanation is that there is no explanation for my DHEA going up. I don't have PCOS or diabetes (I have low blood sugar if anything). Stress can also cause it, but I'm less stressed than I was when it was lower. The only other reason known to medical science has to do with tumors, which could be benign, but the way the doctor said it, it was like something was wrong that I didn't have cancer/tumors.
