Resources for Understanding Hypothalamic Amenorrhea

There are common misconceptions about how hypothalamic amenorrhea / missing periods can arise. “Everyone” seems to know that women who have eating disorders or are Olympic-level athletes commonly lose their periods. What is much less well-known, however, is that women can lose their periods at much less extreme levels of calorie/food group restriction and exercise.

A big part of our book, No Period. Now What? is the survey of over 300 women that we completed, asking a variety of questions about factors leading to hypothalamic amenorrhea, steps taken to recover, and recovery success (as well as trying to get pregnant, pregnancy, and beyond.) From that survey we were able to get a much better picture of the range of women affected by hypothalamic amenorrhea.

Our last few posts have discussed the factors involved in acquiring HA: exercise and undereating, weight/weight loss, stress, and genetics, and also about how women who are not avid exercisers or “underweight” can have HA. But those posts can take a while to read through. So we put together an information sheet to help educate those experiencing missing periods / hypothalamic amenorrhea, as well as any others who might be interested (e.g. doctors, family members). In addition, we’re making the first chapter of our book, which describes the basics of hypothalamic amenorrhea, available for download. Enter your email address to receive an email with a download link for both. Please feel free to share the files: for example with your doctors, other women with HA, and friends or family members who might not understand why your periods are missing.

    Hello. I have been thinking about purchasing this book because I have a Fsh and LH deficiency and was looking for more information because I think it stemmed from my unhealthy diet. Although, I still get my period every month.
