Vulvovaginal itching during pregnancy can be rubbed, but need to clarify the cause of the disease, under the guidance of the doctor to use drugs, not self-medication. Vulvovaginal itching during pregnancy is often considered vulvovaginal pseudomycosis, bacterial vaginosis and non-specific vulvovaginitis. The cause of the disease should be clarified in time and treated with medication if necessary. 1. Vulvovaginal pseudomycosis: it is one of the common diseases of vulvar itching during pregnancy. Due to the low immune function after pregnancy, the local microenvironment of the vagina will be changed, which will lead to the overpopulation of Pseudomonas albicans, and then vulvovaginal pseudomycosis will occur. It can be diagnosed by routine examination of leukorrhea, and local treatment with antifungal drugs such as clotrimazole suppository or miconazole suppository can be given according to the doctor’s instructions. 2. Bacterial vaginosis: it is caused by the decrease of dominant vaginal bacteria, i.e. lactobacillus, and the increase of anaerobic. It can be diagnosed by routine examination of leukorrhea. Anti anaerobic drugs can be given locally, such as tinidazole or metronidazole. 3. Non-specific vulvovaginitis: If no pathogenic bacteria can be found by routine examination of the leukorrhea, the vulvar itching is considered to be caused by non-specific vulvovaginitis, which can be maintained by keeping the vulva locally clean, dry, and changing the underwear, and the symptom will be gradually relieved. Vulvovaginal itching during pregnancy should be timely to the hospital and do routine examination of the leukorrhea, and follow the doctor’s instructions to standardize the treatment, do not unauthorized use of medication, so as not to cause adverse effects on the mother and fetus.
