Keep in mind that your stool isn't going to absorb all the water that comes into your body. Unless you're drinking just enough or are dehydrated--and even then, other parts of your body will absorb what it needs, too. Large amounts of water aren't really going to drastically improve the hydration of your stool, I've read this in many studies. The balance of the water will be peed out.Of course, if you have a UTI, it can be hard to pass urine. That's a symptom of the infection. Also, active painful hemmhoroids can also cause problems releasing urine. Not sure what the actual dysfunction is called, but my gastro told me this is common. Anyway, if you're treating the UTI, eventually this discomfort will pass.That said, I have overactive bladder and my IBS seems to impact how often I pee. Even if I'm not feeling constipated, I may still have painful spasms and need to pee 4 times in 3 hours. There's no pain, just pee pee pee.
