Lost My Leg Hair, Now My Arm Hair is Thinning

(male) Several years ago I lost all leg hair.. Now I am losing arm hair – getting really thin, and I am a little concerned/upset about this. My head hair is pretty decent thus far. I am a 69 year old male in reasonably good heath, with high normal blood pressure which is treated with drugs. Can you recommend what I can do to stop the hair loss. Thanks

Reasonable leg and arm hair growth is a male trait, so I would think of things that are opposite, such as a dropping testosterone level (testosterone supports leg and arm hair), or the presence of some female hormone production (certain tumors can do this). Hair growth on the extremities may be genetically modulated as well. Go see your doctor and check out your hormones.
