Changes in the amount of bleeding and the length of the menstrual cycle are another common women’s disease. Most women have 24-35-day cycles, but at least 20% of women will experience irregular cycles.
The duration of menstrual bleeding is 4-6 days, and the average blood loss during each period is 30 milliliters. If it exceeds 80 milliliters, it is considered abnormal. Women who have bleeding less than once every 21 days or more than once every 35 days, or whose amount of bleeding is more than 80 cc each time, need to be examined.
The most common causes of abnormal uterine bleeding can be attributed to hormonal disorders or the presence of polyps, fibroids, and in rare cases, cancers of the female reproductive system.
