I've been peeing a lot recently and one of the things my doctor has done has been to get me a blood test and a urine test for diabetes, and these turned out negative. The thing I am worried about is that in the week or two preceding the test (I was on holiday, so I couldn't get it done immediately), since I was already worried about diabetes and I wanted to pee less, I ate a lot less sugar than I normally do. Could this have brought my blood sugar down to less than it would normally have been, thus potentially hiding a diabetes problem by producing false negative results? I'm still trying to work out why sometimes I need to pee very frequently and other times I don't need to pee as often, and I'm still wondering whether that is connected with what I'm eating. I know that I tend to suffer from health anxiety, so it is hard for me to know whether this really is a question worth asking, or whether it's my anxiety playing tricks on me before I go to the doctor again.
