The tissues of the vagina are very sensitive to the female hormone oestrogen. This keeps these tissues moist and elastic. It also stimulates the production of glycogen. This helps to regulate the natural vaginal bacteria and protects against infections.
Around the peri-menopause/ menopause, oestrogen levels fall and can trigger uncomfortable vaginal & genital symptoms. These symptoms are very common and can persist ongoing for many women.
Unfortunately, this is not something that is frequently discussed and, as a result, is underdiagnosed and undertreated.
