I’m one who do try to limit my fluid intake to some degree. When I had a violent flare in my bladder I was also asked to do a voiding diary, and i noticed my fluid intake was as low as 1600cc on average, but my voidings was still very high, on average 40-50 voidings over a 16 hour rate, nighttime excluded. I did this due to excessive pain in my bladder at that time.
I was told by a couple of nurses in the urology department, that I had to increase my fluid intake even though it could result in even more voidings. Reason was my urine got too concentrated and that really pushed my bladder over the edge, and meant more pain when I did void.
Now, thankfully my bladder is in remission and I’m now drinking normal amounts of water and coffee, but never more than approx 2.5 liter a day and my voiding frequency has slowed down now, as well as being less painful. I think frequency is around 30-35 on average. However my capacity is only max 100cc now, once in a while I still measure if I’m able to. Simply to check if my condition improves, which it doesn’t seem to do, unfortunately.
I now exactly how much fluid there is in my coffee mug, and the glasses I use, hence why I’m pretty certain about just how much I drink on an average day.
However I’m completely urinary incontinent because of my bladder situation, when I get an urge it’s too late, because my bladder begins pushing violently.
