After menopause, with the decrease of estrogen level in the body, the vulva and vagina will gradually atrophy and become dry, the vaginal mucosa will become thinner, the resistance will be reduced, and it will be easy to complicate the infection. Once the complication of infection occurs, there will be an increase of discharge, which will be manifested as increased leucorrhea, vulvovaginal discomfort and severe itching in some patients. If there are no abnormal pathogens in the leucorrhoea, senile vaginitis should be considered and needs to be treated with medication. A more direct method is a small amount of estrogen supplementation, and a small amount of suppositories can be used in the vagina along with a small amount of estrogen supplementation.
