Fatigue during perimenopause

Perimenopause can bring changing hormone levels, irregular periods and night symptoms that interrupt restorative sleep. Hot flushes or night sweats may leave you awake, while mood changes can make concentration and daily tasks feel harder. Heavy periods can contribute to iron deficiency, which may cause tiredness, breathlessness or dizziness. Fatigue is a presentation of perimenopause, but it can also occur with thyroid problems, low mood, infection or medication effects. A symptom such as fatigue does not by itself identify its cause.

Notice whether tiredness follows poor sleep, a heavy bleed, a missed period or a stressful change. Keeping a brief record of sleep, bleeding, symptoms and medicines can help a clinician see patterns.

Keep a regular sleep and wake time, use a cool bedroom, and reduce evening alcohol or caffeine if these disturb sleep. Gentle activity, regular meals and enough fluids may support energy; pace demanding tasks and plan recovery breaks. If bleeding is heavy or fatigue persists, arrange an assessment rather than starting iron supplements on your own. A clinician may discuss blood tests, thyroid checks, sleep concerns and options for troublesome perimenopause symptoms.

Arrange medical advice if fatigue lasts, worsens, interferes with work or care, or occurs with heavy periods, breathlessness, palpitations, dizziness, low mood or unexplained weight change. Seek urgent help for chest pain, severe breathlessness, fainting, confusion, or bleeding that is sudden and difficult to control.

Could my bleeding or sleep symptoms be contributing to fatigue? Do I need tests for iron deficiency or thyroid problems? Which treatment options fit my symptoms and medical history?
