Frequent heavy periods: what to know

Heavy bleeding may involve flooding through protection, passing large clots, or bleeding that interferes with work, sleep, exercise, or intimacy. When it keeps returning, clinicians may consider changes in the uterine lining, hormone-related ovulation problems, or the transition towards menopause. Conditions such as uterine fibroids, adenomyosis, endometrial polyps, and endometrial hyperplasia can present with heavy bleeding. Polycystic ovary syndrome can also disturb ovulation and alter bleeding patterns. Repeated blood loss may contribute to iron deficiency anaemia, which can cause tiredness, breathlessness, headaches, or a racing heartbeat.

Record the first and last day of each bleed, how often you change protection, clots, pain, medicines, and any bleeding after sex. Arrange a GP or gynaecology appointment, especially if the pattern is new or worsening. Assessment may include a pregnancy check when relevant, blood tests for anaemia, and an examination or scan based on your history. Treatment depends on the cause, your health, and whether you may want a pregnancy; do not start iron or hormonal treatment without advice.

Seek urgent medical help if bleeding is so heavy that you feel faint, weak, confused, or short of breath, or if you have severe pelvic pain, a possible pregnancy, or bleeding that will not slow. Contact a clinician soon for repeated heavy bleeding, bleeding between periods, bleeding after sex, or symptoms of anaemia. These warning signs guide urgency; they do not establish a diagnosis.

Could my bleeding pattern suggest a uterine or ovulation-related cause? Do I need a blood count or iron assessment? Would an ultrasound or other test help? Which treatment fits my symptoms and pregnancy plans? How should I monitor bleeding while waiting for results?
