A member asked:

I run 15-20 miles weekly and have not had my period in 4 months. i eat more than enough calories, is the only way to get it back to stop running ?

A doctor has provided 1 answer

May need lab tests: Given your high level of exercise, you may be underestimating the calories you need daily. Hormonal conditions such as low thyroid or elevated levels of the hormone prolactin can cause periods to stop. Pregnancy can cause periods to stop. A nutritionist can tell you how many calories you need daily, and a doctor can order lab tests to check your hormones.
