Women are prone to mycobacterial recurrence before and after menstruation because their body resistance is low before and after menstruation, and if they do not pay attention to hygiene before and during menstruation, they are prone to mycobacterial vaginitis recurrence. The recurrence of mycotic vaginitis around the time of menstruation is also related to the hormone level around the time of menstruation, especially after menstruation, when the hormone level is low and the blood loss during menstruation makes it easy for the vaginal flora to become imbalanced, which can cause the recurrence of mycotic vaginitis. After effective treatment, mycosis vaginitis needs to be consolidated and preventive medication can be administered before and after menstruation to prevent the recurrence of mycosis vaginitis. Before and after menstruation, pay attention to the cleanliness of the vulva, especially during menstruation, wash the vulva with warm water every day and change the sanitary pads regularly.
