Abnormal Uterine Bleeding (AUB) is among the commonest reasons why women consult gynaecologists. Fortunately for most women, symptoms can easily be controlled to achieve good quality of life.
Common symptoms include: heavy periods, irregular periods (too frequent or too scarce), painful periods, bleeding after menopause and bleeding in pregnancy.
Even though most causes of AUB are transient and have no long-term implications, please consult your gynecologist if you experience abnormal bleeding to exclude rare, but serious causes.
Women under 40 years rarely have any serious causes for their symptoms. Women above 40 years or in their menopause may rarely have potentially serious causes of their symptoms and always warrant a thorough assessment.
The commonest cause is hormone imbalance and this is for various reasons. A regular and predictable menstrual cycle is dictated by well-synchronised hormone signals between glands in the brain and the ovaries. The uterus then responds in a predicable cyclical pattern.
Other causes include: Uterine fibroids, endometriosis, some medications and diseases of the cervix or lining of the womb that may include cancer especially in older women. Rare causes include bleeding disorders that your gynaecologist will look for. For some women, the cause will immediately be apparent following a medical history and clinical examination.

tests
Specific tests may include: hormone tests, ultrasound imaging of the pelvis, taking a biopsy of the lining of the womb and in some cases, further evaluation may include assessing the inside of the womb with a camera (called hysteroscopy).
Some women will require no specific treatment, as the cause may be transient and self-resolving. However, there is a broad range of choices of treatment depending on the cause found. Non-hormonal tablets can be taken during periods to reduce both the amount of bleeding and pain.
Hormonal tablets or injections, especially if contraception is also desired, are especially good in controlling bleeding. An intra-uterine hormone device can also be inserted into the uterus to control symptoms.
Surgical procedures should be considered last as they have more risks, and affect future fertility. Endometrial Ablation is a minimally invasive procedure that uses heat energy to destroy the uterine lining and limit subsequent bleeding.
