A UTI occurs when bacteria (often from the skin or anus) enter the urethra and infect the bladder lining. Since the female urethra is shorter than the male urethra, bacteria can reach the urinary tract more easily, making UTIs more common in women.
During menopause, reduced oestrogen levels make you more prone to UTIs, especially after menopause. Oestrogen helps maintain moist tissues and mucous membranes in the vagina and urethra. It also keeps muscles strong. When oestrogen levels drop, tissues become thinner, drier, and less acidic. Additionally, the muscles of the urinary tract weaken, allowing bacteria to enter the bladder more easily, leading to infection.
A balanced oestrogen level also supports a healthy balance of beneficial bacteria in the vagina and bladder, which help prevent infections. As your body produces less oestrogen, the number of protective bacteria decreases, increasing the risk of infection.
The likelihood of developing a UTI increases during menopause, particularly after your last period. In perimenopause, 36 per cent of women experience recurrent UTIs, rising to 55 per cent in postmenopause. Women over 65 are even more likely to encounter this issue.
Additionally, menopause can bring other symptoms, such as vaginal dryness, reduced libido, and ageing skin. Many women experience three or more symptoms during this phase.
