If you have greenish tofu sludge leucorrhea, you should consider trichomoniasis caused by trichomonas infection or pseudomonal vaginal yeast disease caused by fungal infection. The diagnosis of trichomonas vaginalis can be made through gynecological routines and laboratory tests. 1. Trichomonas vaginalis: Infection from unclean sexual intercourse; indirect transmission through swimming, public baths, toilets and sharing of clothes and towels; douching with vaginal cleansers, which can damage the vaginal microenvironment. Yellowish green discharge, thin, purulent or foamy, with fishy odor, may oxidize to greenish tofu slag leucorrhea over time. 2. Vulvovaginal pseudomonal yeast disease: endogenous infection with pseudomonal yeast, such as direct contact through sexual intercourse or indirect infection through contact with infected clothing, may cause this disease. It is characterized by increased and thick vaginal discharge, greenish bean curd-like leucorrhea, accompanied by odor, burning pain in the vulva and painful intercourse. If you have greenish bean curd-like leucorrhea, you should go to the hospital to have the relevant tests done. For trichomoniasis, metronidazole tablets or tinidazole tablets are commonly used for anti-infection treatment; for pseudomonal vaginosis, nifurtimox vaginal soft capsules and clotrimazole vaginal tablets are commonly used for treatment. In case of mixed infections, the combination of medications should be prescribed and reviewed regularly.
