I have frequent and increased urination although i am not drinking (need to go to the toilet every hour and large amount of clear urine, no pain). no history of diabetes. i only had a migraine/headache, now is improving. what could be and what to do?

This could be a urinary tract infection so a urinalysis with culture is needed. Your doctor also needs to see how concentrated the urine is to see if there is a kidney problem. So, you need to see your doctor for further testing. Good luck to you!

There can be many reasons for this. to begin with the urine has to be tested and depends on findings, other tests for diagnosis. In the meantime cut down on coffee, tea, sodas and alcohol. Hope you do well
