Disease description:

I wasn't careful at the beginning of my period and often used cold water, which led to a lighter menstrual flow. Menstrual irregularity is a very common condition, especially when menstrual blood volume is low. What causes light menstruation in women?

Low menstrual flow in women may be caused by factors such as poor uterine development. If a woman has abnormalities in the uterus, such as underdevelopment, an abnormally small uterus, or other structural issues, it can lead to reduced menstrual blood volume. This mainly occurs because only a small amount of endometrial tissue sheds during menstruation, thereby affecting the amount of menstrual flow. Additionally, if the endometrium is damaged—particularly if it is too thin—women may experience very light periods or even amenorrhea. It is important to stay warm during menstruation; avoid getting too cold and pay attention to keeping the body warm. Also, maintain a nutritious diet during your period.
