Vaginal dryness is a common problem for women during and after menopause, although inadequate vaginal lubrication can occur at any age. Vaginal dryness is a hallmark sign of vaginal atrophy (atrophic vaginitis) — thinning and inflammation of the vaginal walls due to a decline in estrogen.

A thin layer of moisture coats your vaginal walls. When you're sexually aroused, more blood flows to your pelvic organs, creating more lubricating vaginal fluid. But hormonal changes associated with your menstrual cycle, aging, menopause, childbirth and breast-feeding may affect the amount and consistency of this moisture.
