Atrophic vaginitis is characterized by redness, itching, and dryness of the vagina. Over time, there may be narrowing and shrinkage of the vaginal opening and the vagina itself.

A woman’s ovaries make estrogen until menopause, which happens at about 52 years of age. Before menopause, estrogen in a woman’s bloodstream helps keep the skin of the vagina healthy and stimulates vaginal secretions. After menopause, when the ovaries stop making estrogen, or after ovarian failure or removal, the walls of the vagina become thin, and vaginal secretions are lessened. Similar changes can happen to some women after childbirth, but in this case these changes are temporary and less severe.
