Functional Hypothalamic Amenorrhea: Stress, Food & the Hormone Pause Button

---

Gentle, clear guidance on why your period can disappear under stress and under-fuelling — and how to support your body with realistic, hormone-friendly foundations.

Functional Hypothalamic Amenorrhea (FHA) is your brain’s way of saying “pause” when it senses there isn’t enough energy or safety to sustain a cycle. It’s common, often missed, and absolutely not a failure on your part. This guide walks through how FHA happens, the role of stress, food and movement, and where medical care and gentle nutritional support may fit into a recovery plan.

This page gives you a snapshot of key supports and ideas. For the deeper dive — testing, red flags, recovery stages and detailed guidance — you can read the full article.

FHA Support Essentials

Quick Foundations for FHA Recovery

• Eat regularly: aim for consistent meals and snacks across the day rather than long gaps, so your brain stops reading “famine”.
• Dial down intensity: swap high-intensity training for walking, gentle strength work or yoga while your body is restoring.
• Protect sleep: fairly consistent bed and wake times, dimmer lights and less late scrolling all support hormone rhythm and repair.
• Reduce total load: see if there’s one area you can ease back on (extra shifts, over-committing, perfectionism) to give your system breathing room.
• Work with your team: missing or irregular periods deserve a proper check-in with your GP or specialist, especially if there’s weight change, fatigue or an eating history.
