Introduction
Abnormal bleeding during menopause and perimenopause is often due to hormonal fluctuations. In perimenopause, oestrogen and progesterone levels become irregular, affecting the menstrual cycle and leading to unpredictable bleeding patterns. As the ovaries produce less oestrogen, the uterine lining (endometrium) may become thicker or shed irregularly, causing heavy, prolonged, or sporadic bleeding. Other causes may include uterine fibroids, polyps, endometrial hyperplasia, or, in some cases, more serious conditions such as endometrial cancer. Post-menopausal bleeding is always considered abnormal and should be evaluated.
