Changes in your hormonal balance can cause you to urinate more frequently, especially in the early stages of menopause when oestrogen levels fluctuate and decline. Oestrogen plays an important role in the function of the urethra, bladder, and pelvic floor muscles.
When oestrogen levels drop, the tissues around the bladder and urethra can become thinner. This can weaken the pelvic floor muscles, making it harder to hold your urine. At the same time, the urethra can become drier, thinner, or irritated, giving you the sensation of needing to urinate even when your bladder isn’t full.
The bladder can also become more sensitive due to thinning mucous membranes and changes in the bacterial balance, making you feel the urge to urinate more quickly. Lastly, the bladder’s elasticity may decrease, making it harder to retain urine. All these changes contribute to the increased need to urinate that many women experience during menopause.
