My urinary IC is diagnosed as a combination of two causes; First one (there urge part) is neurological and those urges I had since decades - but never were an issue. If an urge built up, I simply "clamped" my bladder sphincter muscle for a few seconds and the urge faded away.
Second cause is my bladder sphincter: since a heart stroke after extremely high blood pressure, heart surgery and a cocktail of meds I have to take until the end of my life there are a few of those meds which not only suppress the heart beat rate and the blood pressure but also can have an effect on bladder (and sphincter) muscles - and I'm one of those where this side effect is obviousley very strong. So, as an result, I have often for some hours an uncontrollable urine dribbling and on the other hand if since then an urge hits (which comes much more often and heavier than in earlier times) they don't fade away any more but build up very quick to pain until I can't hold any more.
My blood pressure and heart problems were solved with the surgery and the meds I have to take, after that I changed my lifestyle with loosing some weight, quit smoking /vaporing, starting daily fitness activities, switching to healthy food and pure water instead of Softdrinks - this all increased my health status to a level I didn't have in the last 20 years. So, no, I had no problems accepting my IC. Wearing diapers does not limit me from any activities, I have an understanding and supportive wife, and in my eyes it's only a minor issue. My eyes are bad, so I wear glasses since decades, now my bladder struggles, so I wear protection - so what?!? There are much, much more annoying things which might happen with getting older, my IC doesn't cause any pain (as long as I don't try to hold in), I have no mobility limitations, it's easy to manage, in my eyes I can be quite lucky with my fate! My doc agreed after deep discussion - as long as I have no issues with wearing protection - to leave it as it is and only start to play around with additional meds or other options whenever I'm not comfortable any more with it
Yes, meds which lower blood pressure and/or heart beat rate (I need several meds for both), don't necessarily, but can also influence someones continence
