Functional hypothalamic amenorrhoea

Periods stopping because of low energy availability, exercise or stress.

Female fertility

When energy intake does not match expenditure, the hypothalamus reduces GnRH pulses and ovulation stops. Recovery usually follows increased energy intake, reduced training load and psychological support, and bone health needs attention. Inducing ovulation without addressing the underlying cause is not recommended.

Also known as: FHA, hypothalamic amenorrhoea, exercise-related amenorrhoea
