Is it safe to assume that since I have always peed a lot, I am OK?

At university (nearly 20 years ago) I had a friend who was the same (or worse) than me. He was a bit of a hypochondriac, went to the doc, got tested for diabetes, and a number of other things. They shoved an endoscope up his parts (most painful thing ever, he said) and told him he had a weak bladder, deal with it. Since hearing that story, I have basically ignored the problem.
