If a ten-year-old girl has leukorrhea, the main thing to know is what color and nature of the leukorrhea is. If the leucorrhea is yellowish in color and occasionally accompanied by vulvar itching or leucorrhea odor, it is caused by vaginitis in young women. It is advisable to take better care of the girl and change her underwear regularly. If necessary, go to the hospital to take the discharge with a cotton swab and have a routine laboratory test of the leucorrhoea, and then give the appropriate treatment according to the results. If a ten year old girl has had her period, her ovaries secrete estrogen and progesterone periodically, leading to an increase in vaginal discharge, which is normal at this time. The leucorrhea is milky white with no odor or a faint fishy smell, so there is no need to intervene clinically, as long as local cleanliness is maintained. If there is an increase in leucorrhea without a menstrual period, but there is no leucorrhea abnormality, it is most likely a sign that you are going to have a period.
