For the light color of the period, mainly due to anemia, further blood tests are needed to clarify the diagnosis. If the blood test indicates anemia, it is recommended to correct the anemia as soon as possible. Light-colored menstrual periods can also be seen in cases of endometrial damage caused by repeated scraping or endometrial destruction caused by Mycobacterium tuberculosis infection, etc. In this case, high doses of estrogen can be considered to stimulate endometrial growth and then observe the change in menstruation. Light color of menstruation can also be seen in anovulatory menstrual disorders. In this case, progestin withdrawal therapy can be given during the second half of menstruation, such as taking oral drospirenone 10mg twice a day for 10 days and then stopping the drug and observing the change of menstrual color, etc.
