If the leukorrhea is gray, you should not assume that there is a problem. You should observe whether there are other symptoms, such as whether the leukorrhea has a bad odor, whether there is vulvar itching, burning at the vaginal opening or pins and needles sensation at the urethra, frequent urination, and urgent urination. If there is, the possibility of vaginitis infection, bacterial vaginitis, trichomonas vaginitis is high, which needs to be observed by the doctor with the naked eye and laboratory tests. If there are no other symptoms and the manifestation is grayish leucorrhea with significantly more than the usual amount of leucorrhea, it should be investigated if it is caused by chronic cervicitis. Before confirming chronic cervicitis, cervical cancer screening should be routinely performed to screen for cervical HPV infection or lesions causing increased discharge with gray color, and if abnormal, symptomatic treatment should be given. If the leucorrhea is gray but not viscous, watery and in high volume, vaginal discharge should be considered for a longer period of time and lesions of the endometrium, fallopian tubes and ovaries should be excluded. If none of the above problems are considered and there are no symptoms, you can try to take foods that nourish Yin and tonify the kidneys or Chinese herbal remedies to assist in the treatment.
