Abnormal Uterine Bleeding (AUB) during perimenopause is a common problem among women.
According to the International Menopause Society, Abnormal Uterine Bleeding (AUB) is bleeding that changes in frequency, duration and quantity and is irregular compared to regular menstrual bleeding. Many women experience it during perimenopause, the transition period that occurs before menopause.
In addition to hormonal changes, the causes of AUBs are usually non-threatening such as the presence of uterine polyps (an overgrowth on the lining of the uterus), uterine fibroids (benign tumors on the uterine wall that are rarely malignant), adenomyosis (a deep growth into the lining of the uterine wall), low thyroid function (observed in one of every four women between ages 40 and 55), as well as other hematological (blood) medical conditions.
The recommendation is for women to be aware of the pattern of their menstrual cycles and consider visiting their doctor before the presence of any of the following warning signs:
- Bleeding that requires changing a pad every hour for a period of 24 hours.
- Bleeding that lasts longer than two weeks.
- Any bleeding that occurs after menopause. This time period varies. Bleeding that occurs twelve months after the last menstruation is considered an AUB.
