well i actually do not have anuria since i urinate more then 50 milliliters a day, but i often have problems with peeing and feel bloated and uncomfortable but wen i drink coffee i have no problems peeing at all, i know coffee is supposed to make you pee more by making your body produce more urine, but i doubt that is all what coffee does because as i have said, lack of urine does not seem to be the problem, so does coffee perhaps do something else?
