I've been peeing a lot more than I usually do, sometimes I go to the bathroom with my bladder full, and 5 minutes later I have to go again and urinate just as much. Even when this doesn't happen, I go about every 45 minutes to an hour and my bladder is always full. This has happened in the past and I went to the doctor and they diagnosed me with streptococcus and gave me antibiotics, but that was about 4 months ago. I've been on a diet, could that be the cause? Should I go see a doctor?
