Leukorrhea thick like tofu dregs is mostly caused by Candida vaginitis, which usually does not affect menstruation and lead to lack of menstruation. However, prolonged prolongation may lead to missed periods. Candida vaginitis is an inflammation of the vulva and vagina caused by the bacterium Pseudomonas aeruginosa. It is mainly characterized by a white, thick, tofu scum-like vaginal discharge, as well as clinical symptoms such as vulvar itching and a burning sensation in the vulva. The inflammation is usually confined to the vulva and vagina and does not affect the uterus or the endometrium, so it does not usually affect menstruation. However, if Candida vaginitis is not treated in time, it may induce cervicitis, and retrograde infection may cause endometritis, which in severe cases may cause menstrual failure or even amenorrhea. If you have a thick white belt like tofu dregs, you need to go to the hospital in time, complete the relevant examination, clarify the cause of the disease, and treat the symptoms under the guidance of the doctor.
