Vaginal dryness isn't something women should just accept and endure. This can cause painful sex, irritation and decrease the quality of your intimacy. Yet many women are reluctant to discuss vaginal dryness – even with their healthcare providers. Vaginal dryness can be caused by a decrease in estrogen and loss of healthy vaginal tissue brought on by a variety of causes including menopause, hysterectomy, medications, breastfeeding and cancer treatments. With an appropriate diagnosis dryness can usually be relieved quickly and successfully.
