Hi There. I Have To Pee Every 15 Minutes Or

Hi there. I have to pee every 15 minutes or so. The urge comes on extremely fast and very strong. I can go from not having to pee to peeing my pants in 10 seconds. I am diabetic, have kidney disease and am over weight by 50 pounds. I also have hypertension and am on Hydrochlorothiazide. I drink at least 2 liters of water a day if not more. I have been eating a lot of candy and sugary things lately.
Thank you,
Duane
