Abnormal Uterine Bleeding is a broad term that covers any form of heavy, prolonged, or irregular bleeding from the uterus. It's not a disease in itself, but rather a symptom of an underlying condition.

- Bleeding between periods
- Bleeding after sexual intercourse
- Menstrual cycles that are longer than 38 days or shorter than 24 days

Impact and Complications

At risk groups

Women at higher risk of AUB include those:
- With hormonal imbalances
- Who are overweight
- With a family history of AUB

Importance of Treatment

Treatment Options

Treatment options for AUB can include hormonal imbalance treatment, uterine fibroids management, and menorrhagia remedies. These can range from medication to surgery, depending on the underlying cause and severity of symptoms.
