Heavy flow during a period: what to know

Heavy menstrual bleeding can reflect changes in ovulation or hormones. Uterine fibroids, adenomyosis, endometrial polyps, and endometrial hyperplasia can also affect how the lining grows or how the uterus contracts. Polycystic ovary syndrome and perimenopause may make bleeding less predictable. Heavy flow is a presentation of several conditions; it does not show which condition is present.

Losing more blood than usual may reduce iron stores. Notice tiredness, headaches, reduced concentration, breathlessness, or paleness, and mention them at an appointment.

Keep a simple record of start and finish dates, the heaviest days, changes of protection, clots, pain, and missed work or activities. Bring a list of medicines and contraception. A clinician may consider an examination, blood tests, and imaging based on your symptoms and reproductive plans. Treatment choices can include medicines or procedures, so discuss benefits, side effects, and fertility goals.

Seek urgent care if bleeding is rapidly soaking protection, you feel faint, have chest discomfort or shortness of breath, or have severe pain. Arrange a prompt review for bleeding between periods, bleeding after sex, bleeding after menopause, or symptoms of anaemia.

Ask what may be causing the pattern, whether you need a blood count or iron test, and whether an ultrasound is appropriate. Ask which treatment fits your pain, bleeding goals, contraception needs, and plans for pregnancy.
