What does periods stopped feel like with hypothalamic amenorrhoea?

Hypothalamic amenorrhoea occurs when the brain temporarily reduces the hormone signals that drive ovulation. This can happen when the body is not receiving enough energy for its needs, when training load is high, during significant stress, or through a combination of factors. Periods can become irregular and then stop. Some people notice feeling cold, low energy, poorer sleep or vaginal dryness, while others mainly notice the missing bleeding. The pattern is not diagnosed from a symptom alone because pregnancy, thyroid problems, prolactin changes and other causes can also alter cycles.

Book a medical appointment and describe recent changes in meals, weight, exercise, stress, sleep and medicines without judging yourself. Pregnancy should be considered when relevant. Assessment may include a history, examination and blood tests for reproductive and thyroid hormones. Care often focuses on restoring adequate energy, adjusting exercise, supporting mental health and treating contributing problems. Ask for guidance before making major training or eating changes, particularly if you feel weak, dizzy or distressed.

Seek urgent help for fainting, chest pain, severe weakness, confusion, severe abdominal pain or a sudden severe headache. Arrange prompt review for a positive pregnancy test with pain or bleeding, repeated dizziness, rapid unintentional weight loss or symptoms of an eating disorder. Long gaps without periods can affect bone health, so do not dismiss the pattern simply because it is painless.

Could my energy balance, exercise, stress or another hormone problem be affecting ovulation? Which tests should I have? How can we protect bone health while my periods are absent?
