The medical term for mycosis fungoides is vulvovaginal pseudomycosis. Vulvovaginal pseudomycosis occurs after menstruation and is mainly related to factors such as reduced resistance during menstruation and poor hygiene habits or discontinuation of medication during menstruation. 1. Decreased resistance during menstruation. When a woman is menstruating, her resistance is relatively weak, and Pseudomyces vulvovaginalis can easily proliferate when her immunity is lowered, leading to the recurrence of vaginal inflammation. To pay attention to enhance their own immunity, can reduce the recurrence of vaginitis. 2. Bad hygiene habits. When women use sanitary napkins or pads for a long time during menstruation, the dampness of the lower body is conducive to the propagation of pathogenic bacteria, coupled with the decline in resistance during menstruation, it is easy to lead to the recurrence of vaginal inflammation. Pay attention to the hygiene during menstruation, change sanitary napkins and pads regularly, and keep the vagina clean and dry. 3. Stop taking medication during menstruation. Due to the discharge of menstrual blood during menstruation, it is not suitable for the treatment of vaginal inflammation with topical medication. Stopping the medication during menstruation may allow the growth and reproduction of molds that have not been cured, which will lead to recurrence of the inflammation phenomenon. It is generally recommended not to use topical vaginal medication during menstruation, but to take fluconazole and other anti-fungal medications under the guidance of a doctor. After menstruation and the occurrence of vulvovaginal pseudomycelium yeast disease to follow the doctor’s instructions to use sodium bicarbonate solution cleaning, built-in mycophenolic vaginal soft capsules or clotrimazole suppositories and other medications, the treatment is strictly prohibited during sex, with oral fluconazole to consolidate the therapeutic effect, pay attention to the review, and so on.
