Leukorrhea that is yellow is usually seen in gynecological inflammation, most commonly vaginal inflammation, such as atrophic senile vaginitis, infantile vulvovaginitis, bacterial vaginitis, mycobacterial vaginitis, trichomoniasis, etc. For leucorrhea that is yellow, it is important to take into account the patient’s clinical manifestations, such as the presence of vulvar itching, the presence of vulvovaginal pain, any change in the nature of the discharge, and whether it is a beanbag, curd-like or foamy discharge. If these changes are combined, the vaginal discharge needs to be examined and the next step in treatment will be decided based on the laboratory examination of the vaginal discharge. For age-related atrophic vaginitis, topical estriol ointment is usually used vaginally. For trichomoniasis, couples need to be treated with metronidazole tablets, etc.
