Abnormal uterine bleeding (AUB) refers to bleeding from the uterus that is irregular in volume, duration, or timing and is unrelated to normal menstruation. It can manifest as heavy menstrual bleeding (menorrhagia), bleeding between periods (metrorrhagia), or prolonged periods (menometrorrhagia). Causes of AUB include hormonal imbalances, uterine fibroids, polyps, endometriosis, and thyroid disorders. It can also be linked to more serious conditions like uterine cancer or bleeding disorders.

Diagnosis involves a thorough medical history, physical examination, and tests such as blood work, ultrasound, and endometrial biopsy. Treatment depends on the underlying cause and may include hormonal therapies like birth control pills, non-hormonal medications like NSAIDs, or surgical interventions such as hysteroscopy, endometrial ablation, or hysterectomy.

Addressing AUB is essential for improving quality of life and preventing complications like anemia. Regular gynecological evaluations are crucial for early detection and effective management.
