Symptoms advice please.....already seen GP

Hi there i'm nick and this is my first post. I have been having a few symptoms which I have looked up on the internet which points to diabetes, here are a few of my symptoms

* frequent urination - last night I was up 6 times to go to the loo!!
* Increased thirst
* Tiredness
* pins and needles in my hands and feet

I notice that I am hungary all the time and when I do indulge on sweet things a couple of hours later I dont feel too good, as if I have a drunk dizzy, lightheaded feeling.

I went to the doctors today told them my symptoms and tested my urine but there was nothing in it, no indication of a urine infection or glucose in my urine. They told me they were not sure and advised to drink plenty to "flush" anything out if I did have anything and too see them next week if still have concerns.

I am just wondering if it was diabetes would it show up in your urine or not or would a blood test be more accurate, there is no family history either.

Just wanting some advice really what to, would I be better off asking for a blood test instead, or is a urine sample just as accurate?

Many thanks
Nic

Thanks for the info, much apreciated.

Do you know though whether a negative urine sample indicates no diabetes. I'm only asking so I know whether to insist on a blood test or GTT.

Thanks

Thanks alot, I just assumed that because no glucose was detected in my urine sample then it could not be diabetes, although after I informed the practice nurse of my symptoms she did not seem that concerned and not even mentioned the possibility of diabetes, and that it is prob a chill of the kidneys???? She did say to go back if the symptoms persist.

I am concerned but dont want to waste their time either, how long should I leave it if symptoms do continue?? Would you consider it to be normal to feel "heavy" headed and dizzy after eating as I have just eaten some pasta and i'm getting that feeling again with pins and needles in my hands.......maybe i'm just wierd lol!

Thanks
