Vaginitis generally regardless of age. Vaginitis is inflammation of vaginal mucosa and submucosal connective tissue, which is a common disease in gynecological clinic and can occur at all ages. Under normal physiological conditions, the anatomical and biochemical characteristics of vagina are enough to prevent the invasion of external microorganisms. If it is destroyed, pathogenic bacteria can take the opportunity to enter and cause vaginal inflammation. Clinically, the main manifestations are leucorrhea change, pruritus and burning pain of vulva, and there may be symptoms such as sexual intercourse pain, dysuria and urgency. I suggest you go to the doctor for a routine gynecological examination first. If you are infected with vaginitis, you need active treatment. The treatment time varies from person to person.
