Understanding Heavy Menstrual Bleeding and When to See Your GP

Understanding what heavy bleeding means

Heavy menstrual bleeding (also called menorrhagia) describes periods that are heavier or longer than usual and affect your comfort, energy, or daily life. Bleeding is considered “heavy” when you soak pads or tampons frequently, pass large clots, bleed for many days, or feel physically unwell because of your period. If your bleeding worries you, feels different to your normal pattern, or disrupts daily functioning, it deserves medical review.

What heavy periods may feel like

You may notice flooding through pads or tampons, needing to change protection very often, passing clots, bleeding longer than usual, pelvic discomfort, cramping, tiredness, low energy, or symptoms of low iron such as dizziness, breathlessness, or pale skin. Some people also experience emotional strain, anxiety about leaving the house, embarrassment, work or school disruption, or sleep disturbance.

Why heavy bleeding happens

There are many possible causes. These may include hormonal changes, ovulatory problems, uterine fibroids, endometrial polyps, adenomyosis, endometriosis, thyroid disorders, bleeding disorders, infections, or the effects of some medications or treatments. Sometimes no serious cause is found — but assessment is still important to ensure safety and support.

When heavy bleeding needs urgent attention

Seek urgent care if you soak through pads or tampons every hour or sooner, feel faint or weak, experience severe abdominal pain, or suspect you may be pregnant. Very heavy bleeding after childbirth, miscarriage, or a medical procedure requires immediate medical review.

When to see your GP

See your GP if heavy periods persist, worsen, keep returning, interfere with work, school, family life, or sleep, or if you feel unwell. Earlier review is especially important if you are under 18, approaching menopause, over 40 with new changes, have a bleeding disorder, take blood-thinning medication, or are concerned about fertility or pregnancy.

How your GP supports assessment and care

Your GP listens to your concerns, asks about your menstrual pattern, medical history, pregnancy history, sexual health, medications, and symptoms such as pain or fatigue. Assessment may include examination, blood tests (such as iron levels and hormones), and imaging when needed. Care is individualised, focusing on treating the cause (when identified), supporting safe bleeding control, preventing anaemia, reducing pain, and protecting wellbeing. Referral to a gynaecologist may be recommended for complex cases, unclear causes, fertility concerns, or when specialist treatment options are appropriate.

Your quality of life matters

Heavy bleeding is not something you must “just tolerate.” If your period affects your physical health, social life, work, confidence, or emotional wellbeing, support exists. Talking with your GP is not only medically sensible — it helps you feel heard and supported.

A reassuring message

Heavy menstrual bleeding is common and treatable. With the right care, many people achieve better bleeding control, improved comfort, stronger energy levels, and a better quality of life. You do not need to manage it alone — speaking with your GP is a safe and supportive first step.
