Does hypothalamic amenorrhoea cause missed period?

The hypothalamus helps regulate the hormone signals between the brain and ovaries. When the body senses inadequate energy, heavy training, major stress, or significant weight change, those signals can slow. Ovulation may then be delayed or not occur, and a period may be missed. A missed period has several possible causes, so it does not confirm hypothalamic amenorrhoea by itself.

Consider pregnancy first if it is possible. Record the date of your last bleed and any changes in food intake, exercise, stress, weight, sleep, or medicines. A healthcare professional can review your history and may recommend pregnancy testing, hormone checks, and tests for other conditions. Management usually addresses the underlying energy or stress imbalance rather than simply inducing bleeding.

Book a clinical review if a period is missed without a clear explanation, if missed periods recur, or if you have symptoms such as persistent headaches, vision changes, pelvic pain, or breast discharge. Seek urgent help for severe pain, heavy bleeding, collapse, or marked weakness.

What causes should we check after my missed period? Could my activity or nutrition be affecting ovulation? Which hormone tests are appropriate? How can I support recovery and protect bone health?
