“Vaginal atrophy used to be a medical term for thinning and drying of the vagina’s inner lining, often after menopause. Another name for it was atrophic vaginitis. These terms are no longer used. The physical changes they described are now considered to be part of a group of symptoms that affect the genitals and lower urinary tract, called genitourinary syndrome of menopause (GSM).”
