History of anorexia but now I have my periods. FSH, LH, and estradiol normal but progesterone is too low in luteal phase. Severe dry eyes. Why?

Follow up visit. If you are now having periods and your FHS and LH are normal then things are probably ok. We would not normally treat a low Progesterone level in these circumstances. If you wanted to treat it then you could go on birth control pills. This would normalize both your Estrogen and Progesterone. A primary care doctor can evaluate your dry eyes.
