With age, every woman enters menopause, after which her ovaries gradually lose their function and she enters old age, after which her organs begin to decline with one problem or another. The symptoms of senile vaginitis are usually mild, but due to ovarian atrophy and loss of function, the ovaries cannot continue to secrete estrogen. The main manifestations are atrophy of the vaginal wall, thinning of the mucous membrane, reduction of local glycogen content and increase in pH, all of which are detrimental to the self-purification function of the vagina itself. When autoimmunity is low or local immunity is low, pathogenic bacteria multiply and lead to the development of senile vaginitis. The most common symptoms of geriatric vaginitis include itching and burning of the vagina and vulva, and discomfort such as lower abdominal cramps. Although the symptoms are generally mild, they have a serious psychological and life impact on the elderly because of the long duration of the disease, the difficulty in healing, and the recurrent attacks. And if there is a delay in the disease, it may accumulate the urethra and cause discomfort such as frequent and painful urination. Therefore, if an elderly woman once appears, discomfort such as bloody leucorrhea and vulvar itching, she should consult a doctor in time to exclude by other diseases, then she can be diagnosed with senile vaginitis. The treatment of senile vaginitis is to strengthen exercise, pay attention to personal hygiene and increase personal resistance; use estrogen preparations to fundamentally solve the situation of estrogen deficiency, but improper application of estrogen can cause an increased risk of endometrial cancer, so it must be adapted under the guidance of a doctor.
