Vaginitis in the elderly is mainly related to the decline of ovarian function and lower estrogen levels in women. Patients can be treated as follows: 1. Use medication according to the source of infection. For example, if the patient has bacterial or trichomonas infection, she can use tinidazole suppositories; if she has mycobacterial infection, she can use clotrimazole vaginal tablets; if no specific infectious agent is detected, she can use bitter ginseng gel or povidone suppositories. 2. It can improve the vaginal environment of women, improve their vaginal resistance and reduce the recurrence of vaginitis, and this local use of estrogen has little effect on the whole body. However, if local estrogen is not effective, oral estrogen should be used for treatment, and a full body check should be performed to rule out contraindications before use.
