Hormones do affect the bladder, some people experience an increase in swelling, pressure, pain, and frequency when oestrogen levels are highest. This is believed to happen because oestrogen increases mast cell secretion, therefore increasing inflammatory reactions. Others however feel better when their oestrogen levels are high.
Researchers believe that bladder pain sufferers may benefit from the increase in the thickness of the bladder lining and the lack of progesterone during this time.
To add to the complicated picture, another group feel best and experience less symptoms during their period, when hormone levels are low. Finally others experience bladder pain during their periods.
Where sufferers can agree is that almost all complain of increased ‘flare’ symptoms a few days prior to the onset of their period. The lower oestrogen levels and higher progesterone levels make people more susceptible to bladder symptoms around this time. High levels of progesterone can cause frequent urination as progesterone acts like a diuretic. The sacral nerve which controls the pelvis and its organs is full of oestrogen receptors. Research published in The International Urogynecology Journal in 1993 showed a change in hormone levels, in particular that of progesterone, may affect the excitability of the nerves and make you feel like you have to urinate more frequently.
I'd look into this further. Sadly urologists don't easily relate bladder issues to hormone problems - you may need to be your own detective in all of this.
