What does a missed period feel like with hypothalamic amenorrhoea?

Hypothalamic amenorrhoea occurs when the brain reduces the hormone signals that support ovulation. A missed period may therefore feel like nothing at all: you notice that the expected bleeding has not happened. Some people have increasingly long cycles before periods stop, while others notice lighter bleeding first.

The pattern can appear during emotional stress, demanding training, low energy intake, significant weight change, or a combination of these factors. Lower oestrogen activity may contribute to vaginal dryness, discomfort with sex, hot flushes, or reduced bone strength over time. Other causes of absent periods can look similar, including pregnancy, so an evaluation matters.

Record your bleeding pattern, meals, exercise, sleep, stress, weight changes, injuries, and symptoms such as dryness or low energy. If pregnancy is possible, take a pregnancy test. Make an appointment with a clinician rather than increasing training or restricting food while waiting for an explanation.

Assessment may include a health history, examination, and tests for pregnancy and other hormone conditions. Treatment usually focuses on the factors affecting hormone signalling and protecting bone and general health; the plan should be tailored to your situation.

Arrange medical care for an absent or repeatedly irregular period, especially after a major change in exercise, eating, stress, or weight. Earlier assessment is sensible when you have a history of stress injuries, persistent fatigue, dizziness, or symptoms of low oestrogen.

Seek urgent help for fainting, severe weakness, chest pain, severe abdominal pain, or heavy bleeding after a long gap. Tell the clinician about possible pregnancy and any medicines or supplements you use.

Could my energy intake, training, stress, or another condition be affecting ovulation? Which tests are appropriate? How can I support bone health and recovery? What symptoms should prompt an earlier review?
