As a pediatrician, I was not asking enough questions about my patients' periods. We ask when the last one was. We rarely go deeper than that. And after this conversation, I will never approach it the same way again.
I sat down with my friend and colleague Dr. Natalie Crawford, reproductive endocrinologist, fertility specialist, and author of The Fertility Formula. Here is what I want every parent raising a girl to understand: the menstrual cycle is not just a monthly inconvenience. It is one of the most important windows into your daughter's hormonal health, her long-term fertility, and her overall wellbeing. And the symptoms we keep brushing off as "just puberty" or "just a bad period" are often the first clues to conditions that will matter deeply later in life.
In this episode, we cover:
Why the menstrual cycle is a vital sign and what that means for the girls in your life
The warning signs parents and pediatricians too often dismiss as normal
What a first period should actually look like, and when irregular cycles need to be taken seriously
Hypothalamic amenorrhea: the condition linked to over-exercising, under-eating, and chronic stress that silently affects estrogen during some of the most critical years of development
PCOS in teens: why it does not always look the way doctors expect, and why so many girls get missed
Thyroid disease and how it shows up in the menstrual cycle before anything else
Endometriosis in adolescents: when period pain is not normal and what to do about it
Why birth control is sometimes the right treatment but not always the full answer
How to advocate for your daughter when you feel dismissed at the doctor's office
The referral path from pediatrician to OB to specialist, and when to push for more
