Fatigue in women

Heavy or prolonged periods can contribute to anaemia, especially when fatigue occurs with paleness, headaches, dizziness, or breathlessness. Pregnancy, perimenopause, pain, hot flushes, and disrupted sleep can change energy levels. Caring responsibilities, burnout, anxiety, and low mood may drain energy too. Coeliac disease, kidney disease, infection, thyroid problems, and medication effects are other possibilities. Fatigue does not point to one diagnosis by itself.

Keep a simple diary of sleep, periods, bleeding, pain, mood, food, fluids, and fatigue. Eat regular nourishing meals, drink enough to avoid dehydration, and build gentle activity around your energy. Protect rest and share care tasks when possible. Arrange a clinician review rather than self-treating with supplements; an examination and selected blood tests can clarify whether anaemia or another problem is present.

Book an appointment when fatigue persists, returns repeatedly, or interferes with work, caring, exercise, or daily tasks. Seek prompt care for very heavy bleeding, black stools, fever, unexplained weight change, worsening breathlessness, fainting, or severe low mood. Emergency help is needed for chest pain, collapse, severe breathing difficulty, or thoughts of harming yourself.

Could my periods, pregnancy status, medicines, sleep, or mood be contributing? Do I need a blood count or other tests? How should heavy bleeding be evaluated? Which treatments or supplements are safe if I may be pregnant? What symptoms would make this urgent?
