Atrophic vaginitis (also known as vaginal atrophy or urogenital atrophy) is an inflammation of the vagina (and the outer urinary tract) due to the thinning and shrinking of the tissues, as well as decreased lubrication. These symptoms are due to a lack of the reproductive hormone estrogen. The most common cause of vaginal atrophy is the decrease in estrogen which happens naturally during perimenopause, and increasingly so in post-menopause. However this condition can occur in other circumstances that result in decreased estrogen such as breastfeeding and the use of medications intended to decrease estrogen to, for example, treat endometriosis. The symptoms can include vaginal soreness and itching, as well as painful intercourse, and bleeding after sexual intercourse. The shrinkage of the tissues and loss of flexibility can be extreme enough to make intercourse impossible. == Symptoms and signs == Genital symptoms include dryness, itching, burning, soreness, pressure, white discharge, malodorous discharge due to infection, painful sexual intercourse, bleeding after intercourse. In addition, sores and cracks may occur spontaneously. Atrophic vaginitis is one possible cause of postmenopausal bleeding (PMB). Urinary symptoms include painful urination, blood in the urine, increased frequency of urination, incontinence, and increased likelihood and occurrence of infections. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Atrophic vaginitis」の詳細全文を読む スポンサード リンク
