Do you wake several times in the night to go to the loo?
Hormonal shifts during the menopause can thin the lining of your bladder, affect your pelvic muscles and weaken the sphincter muscles (the ones that keep your pee in).
This can be treated, and many women find restoring their hormone levels through HRT or vaginal estrogen pessaries can be particularly helpful in regaining control and an undisturbed sleep.
