Itchy vulva at the end of each period can be caused by vaginal inflammation and lack of hygiene, as follows: 1. Women’s resistance and immunity are very poor during menstruation, which can easily induce vaginal inflammation, or previous vaginal inflammation, which can cause vaginal inflammation to recur; 2. The vagina is bleeding continuously during menstruation, and blood is a good medium for bacteria. If you don’t pay attention to the cleanliness of your vulva, change your underwear and underwear, or change your sanitary napkin, it may cause gynecological vaginal inflammation. Therefore, women should pay extra attention to hygiene during menstruation, change their underwear and underwear regularly, and prohibit the consumption of spicy and stimulating foods.
