Symptoms of hyperthyroidism in women

An overactive thyroid releases more thyroid hormone than the body needs. This can speed up the heartbeat, bowel movements and the way the body uses energy. Some people notice trembling, muscle weakness, tiredness despite feeling wired, or changes in menstrual bleeding. A thyroid swelling or eye irritation can also occur, although symptoms vary. These features can have other causes, so they do not establish the diagnosis by themselves.

Arrange a primary-care appointment if several symptoms persist, interfere with sleep, or appear together. A clinician may examine your neck and pulse and arrange thyroid blood tests. Keep a brief record of palpitations, bowel changes, sleep, periods, medicines and supplements. Do not start iodine products or change prescribed thyroid treatment without medical advice.

Seek urgent medical help for chest pain, fainting, severe breathlessness, confusion, or a very fast or irregular heartbeat. Prompt assessment is also sensible for worsening weakness, persistent vomiting, or symptoms during pregnancy, because thyroid imbalance may need closer monitoring.

Ask which thyroid tests are appropriate, whether medicines or supplements could be contributing, how symptoms may affect menstrual cycles or pregnancy, and which heartbeat or heat-related changes should trigger urgent help.
