NCT ID NCT06583408

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study is building a large registry of women with Functional Hypothalamic Amenorrhea (FHA), a condition where the body stops having periods due to stress, low weight, or excessive exercise. Researchers will track up to 100,000 participants over time to learn how common FHA is, who it affects, and how it impacts long-term health. No treatment is given; the goal is simply to collect information through questionnaires and medical records.
