Abnormal Uterine Bleeding
Abnormal uterine bleeding means menstrual or uterine bleeding that is unusually heavy, prolonged, irregular, occurs between periods or happens after menopause.
Key takeaways
- A pregnancy test is an important early check when pregnancy is possible, even if bleeding resembles a period.
- Causes include ovulation changes, fibroids, polyps, medicines, thyroid problems and disorders of the uterine lining.
- Treatment depends on the cause, blood loss, anaemia risk, age, contraception needs and plans for pregnancy.
The listings below do not identify the cause of bleeding or suit every person; clinical assessment should guide treatment.
What evaluation may involve
The pattern and amount of bleeding, pelvic pain, cycle history and current medicines provide useful clues. Depending on age and symptoms, assessment may include a blood count, pregnancy testing, thyroid tests, pelvic imaging or examination of the uterine lining. Any bleeding after menopause warrants medical assessment.
How medicines may help
Hormonal treatments can reduce bleeding or regulate cycles in selected cases. Non-hormonal options may also reduce heavy flow. Choice is individual because clot risk, migraine history, liver disease, possible pregnancy and the underlying diagnosis affect safety.
When to seek urgent care
Seek urgent care for soaking through pads repeatedly, fainting, marked weakness or breathlessness, severe or one-sided pelvic pain, fever with pelvic pain, or pain and bleeding when pregnancy is possible.
