Some advice please

Dear all, I havent been diagnosed with Diabetes yet, but I seem to have a few symptoms of type 2, my Dr is very unhelpful, so I'm hoping members here can give me some advice please.

Over the last ten years I have tiredness after eating, which has become so bad now that I feel sedated, have blurry vision and quite often I struggle to stay awake. After eating carbs I cant function as a human anymore.

I have suffered from depression for many years, every time I went to the Dr about this tiredness if would be fobbed off as a symptom of depression, however the tiredness is extreme now.

I have a low appetite however for some reason I am putting on weight, I definitely was not eating an excess of calories, in fact I probably only managed to eat 1000 calories a day, I wanted to join the gym and decided to try and eat aleast 2500 calories per day which I have read is normal for a male.

After lots of research and reading, I bought a Glucomen Areo, and regularly found my blood sugar to be between 12-15.9 mmol two to three hours after eating.

I took the readings for a week and went to the Dr who immediately said finger prick tests are not accurate. I then had a fasting glucose reading taken which was 6.something, this was after fasting for 16 hours.

After this I cut out carbs completely and immediately felt better. A few weeks later I had a hba1c test along with a finger prick test at the same time, the finger prick showed glucose at 7mmol but the blood taken intravenously apparently only showed 5.1mmol. According to the Dr hab1c was normal.

However I had already cut out carbs completely, and due to my low appetite I doubted the hba1c test would show anything. Only upon trying to eat normally did symptoms appear, I feel the lack of eating carbs and not eating enough would skew the result. Can anybody advise if this is the case?

I asked for an oral glucose tolerance test however the Dr is fobbing me off and saying you dont need eat carbs at all for a hba1c test to be accurate.

I have tried eating carbs again since Monday this week and again have glucose readings over 10mmol according to the meter, along with extreme tiredness, lack of concentration and zero motivation to do anything.

Is an hab1c test useful for a definitive diagnosis? As I really dont fancy eating carbs for 3 months.

Can anybody advise me further please?

Thanks

Thank you both for the welcome and replies, I am not sure what hba1c reading was, the Dr just said its normal, I have tried a zero carb high fat diet and felt so much better, blood readings were much lower, after reintroducing carbs to my diet the blood glucose readings went up again, however my Dr is still claiming a glucose meter is not accurate.

I'm unsure of how respond and get to the bottom of this issue, as from what I have read blood glucose should not go above 7mmol for a non diabetic.

Thank you HSSS, in the practice I go to its usually locum Dr's, however I do see one of the permanent ones (which is the one refusing to believe anything I say) today I was told categorically not eating carbs would not affect my hba1c reading, I also stated previously to the Dr that I am not eating carbs at all so there is no point in the hba1c test.
