I just had my cholesterol levels checked for the first time and they are abnormally low. My total is 100, triglycerides are 79, HDL (good) are 52, and LDL (bad) are 32!!! My doctor said this is the lowest she has ever seen. She asked about my diet and I assured her it's normal and she was reassured. Should I be worried about these low results? I went to see her because my period has been very erratic for a while now(~1 year); very light and late. My hair also had a mass falling-out about a year ago and is still much thinner than it was before. However, I feel fine overall. Should I be worried?
