Vaginitis, also known as vulvovaginitis, is inflammation of the vagina and vulva that causes symptoms like itching, burning, pain, discharge, and odor. It is usually caused by a change in the normal balance of vaginal bacteria due to infection or reduced estrogen levels after menopause. Common causes include bacterial vaginosis, fungal infections like candida, and viral infections such as influenza. Diagnosis involves vaginal examination, pelvic exam, urine test, pap smear, and sometimes biopsy or colposcopy. Treatment consists of antibiotics, antifungals, or antivirals depending on the cause, along with practices like keeping the vaginal area clean and dry
