Genitourinary syndrome of menopause is the changes to the lining of your vulva and vagina (atrophic vaginitis) and the resulting changes to your urinary and sexual function (peeing and sex) which can happen at menopause.
Atrophic vaginitis is a condition where the lining of your vagina gets drier, thinner and less stretchy because of a lack of oestrogen.
It’s most common in women going through menopause because oestrogen levels drop a lot at this time. However, it can also occur in younger women and people assigned female at birth, due to breastfeeding, cancer treatment or having your ovaries removed, which reduces oestrogen levels. Some birth control pills or medicines that counteract oestrogen, (eg, tamoxifen) can cause these symptoms too.
Symptoms include burning, itching, spotting, pain during sex, and needing to urinate (pee) often.
When your body has less oestrogen, you also produce less vaginal fluid and the acid balance in your vagina changes which can irritate your vaginal tissue.

Note: The lack of oestrogen that happens at the time of menopause is different from low levels of oestrogen in children due to differences in sex development.
