Thinning of the lining of the vagina due to decreased production of estrogen.
Atrophic vaginitis is an inflammation of the vagina due to thinning and shrinking tissues and a decrease in lubrication. Atrophic vaginitis is typically caused by a decrease in estrogen levels that normally drop after menopause. The disorder may occur in younger women after surgical removal of the ovaries. Some women may develop the condition immediately after childbirth or while breastfeeding, due to low estrogen levels at these times.
