What things could be a reason for frequent urination?

Question

I'm a fifteen year old boy, and in the last hour and a half alone, i've urinated three times without eating or drinking anything.

I know frequent urination can be a symptom of several diseases, but i don't have any other symptoms right now.

Any ideas?

Answer 1

Too much salt in your diet can cause fluid retention.  Eventually your body had to get rid of it and the only way is either through urination or sweating.  I wouldn't think you have anything to worry about except finding something to do that will take your focus off the fear of some devastating disease.

Did you know that stress or nervousness will make you urinate more?

Answer 2
