Abnormal uterine bleeding (AUB) refers to any irregular or unusual bleeding that differs from a normal menstrual cycle. It may present as heavy periods, irregular cycles, prolonged bleeding, or spotting between periods. AUB can arise from a range of causes, including hormonal disturbances, structural changes in the uterus, or underlying medical conditions.
Common Causes of Abnormal Uterine Bleeding:
Hormonal Imbalances: Fluctuations in hormone levels, such as those seen in conditions like PCOS or thyroid disorders, can disrupt normal menstrual cycles.
Uterine Fibroids: Noncancerous growths in the uterus that may lead to heavy or extended menstrual bleeding.
Endometrial Polyps: Benign growths in the uterine lining that can cause irregular or unexpected bleeding.
Pelvic Inflammatory Disease (PID): Infections of the reproductive organs that may result in abnormal bleeding patterns.
Endometriosis: A condition where tissue similar to the uterine lining grows outside the uterus, often leading to pain and irregular bleeding.
