You Lost Your Period… Now What? Understanding Hypothalamic Amenorrhea

You’re exercising, eating “clean,” staying productive, checking all the wellness boxes… and then one day your period just disappears. Maybe it’s been three months. Maybe six. Maybe your doctor told you to “just relax” and it’ll come back. But what if your missing period is actually your body trying to tell you something important? In this episode, Dr. Lucky Sekhon and Dr. Alicia Robbins break down hypothalamic amenorrhea (HA) which is a surprisingly common but often overlooked condition where the brain essentially presses pause on ovulation and menstruation in response to stress, under-fueling, overtraining, or low energy availability. The conversation explores the hidden ways modern wellness culture can contribute to HA, from restrictive “clean eating” and intermittent fasting to burnout, perfectionism, chronic anxiety, and the pressure to constantly optimize. They unpack how hypothalamic amenorrhea differs from PCOS, the labs and imaging every woman should ask for, and why missing your period is about far more than fertility, it’s also a warning sign for your bones, heart, metabolism, and long-term health. IF YOU’RE TEXTING YOUR FRIENDS LIKE... You: Wait… I haven’t had a period in four months.
