I'm a 38yr old female. The hair on my legs and under my arms no longer grows. My pubic hair is almost all gone? Could you give me any reason why?

Causes of hair loss. Hair loss on the legs can be caused by poor circulation, diabetes, thyroid disorders, peripheral arterial disease, medications, poor diet, smoking, being overweight, anemia, other hormonal disorders, and genetics. Hair loss in the pubic area and under the arms can be caused by thyroid disorders, medications, anemia, genetics, other hormonal disorders and alopecia. I recommend a medical workup.
