If we are talking about having a piss, then frequent is relative. At the time of my Type 1 diagnosis I was consuming about 8 liters of water a day and urinating every 30-40 mins, even during the night. If there is significant weight loss even though you might consume 4000-6000 cals per day then I'd get straight down for a check. You don't want to f**k around with diabetes. It's a sh1t condition to have.
