What should you know about heavy blood flow during period?

A clinician can ask about the pattern, examine you when appropriate, and check for anaemia or a condition affecting the uterus or hormones.

Heavy periods may involve bleeding that lasts longer than expected, needing to change menstrual products unusually often, passing clots, or avoiding work, school, exercise, or sleep. The amount can be difficult to judge at home, so the pattern and its impact are useful information.

Possible contributors include uterine fibroids, adenomyosis, endometrial polyps, endometrial hyperplasia, polycystic ovary syndrome, and the hormone changes of perimenopause. Ongoing blood loss can contribute to iron deficiency anaemia, which may cause tiredness, breathlessness, dizziness, headaches, or paleness. A heavy period is a symptom, not a diagnosis.

Record when bleeding starts and stops, how often you change products, whether clots occur, and any pain, dizziness, or fatigue. Note medicines, contraception, bleeding between periods, and whether pregnancy is possible. Arrange a clinician appointment if the pattern is new, worsening, or interfering with normal life.

Assessment may include a pregnancy check when relevant, blood tests for anaemia, and an examination or ultrasound based on your symptoms. Treatment depends on the cause and may include medicine or treatment directed at a uterine or hormonal problem. Do not start iron or bleeding medicines without advice, especially if you take other medicines or could be pregnant.

Seek urgent medical help if bleeding is very heavy and you feel faint, confused, unusually weak, short of breath, or have chest discomfort. Get prompt assessment for severe or worsening pelvic pain, bleeding after pregnancy may be possible, or bleeding that does not settle. If you are soaking through products repeatedly or cannot keep up with fluid intake, do not wait for a routine appointment.

Ask what could be driving the change, whether your blood count and iron need checking, and which treatment choices fit your health, contraception, and pregnancy plans. Ask what warning signs should bring you back sooner and when to review the plan if bleeding remains heavy.
