By definition hyperglycaemia is blood glucose above normoglycaemia. This is certainly at a level of 200mg/dl which works out at 11.1mmol/l. That's the level required to diagnose diabetes (a condition defined by hyperglycaemia) with a random blood test.
patients with severe hyperglycaemia such as those who present with severe classic hyperglycaemic symptoms or hyperglycaemic crisis can continue to be diagnosed when a random (or casual) plasma glucose of ≥200 mg/dl (11.1 mmol/l) is found.
The level at which you feel hyperglycaemic, or indeed hypoglycaemic depends on the levels to which you have become accustomed.
A gradual rise over months can be insidious. This is why some, mainly elderly people with T2, whilst avoiding DKA because they produce enough insulin, can gradually rise to levels of over 40mmol/l and end up very sick indeed .

Martina79,
the urine test that you originally had, though a blunt instrument would certainly have detected glucose levels of above 10mmol/l which is the normal renal threshold.
From one of your posts I have deduced that you now have the results of an HbA1c and that was 6.4% .
As you seem to realise, this is just below the cut off point of 6.5% for a diagnosis of diabetes.

An
estimated average glucose level for the last 2-3months would be 7.6mmol/l. (notice the unit, it's not the same as the percentage figure shown in an HbA1c result and is quite different. It's always important to include units so people can understand what you are writing about).
The lower glucose levels you mention could be reactive hypoglycaemia. This is suggested by some authors to sometimes be an symptom of pre diabetes. It may be that the pancreas produces too much insulin in response to hyperglycaemia after meals, leading to subsequent hypoglycaemia.

As with T2 diabetes, diet and exercise are key features in it's management.
As an earlier poster said, the potentially serious hypoglycaemia associated with some people who have diabetes is related to an imbalance between certain medications (usually insulin or sulfonylureas) and food or exercise. It is potentially dangerous because the insulin or other drug may continue to lower levels and cannot be withdrawn from the body. This is not the case with 'reactive' hypoglycaemia.
This paper makes quite clear the causes in people with diabetes:

i dont know why people in uk underestimate what i am saying, esspecialy those who dont absolutely know me.
Finally, I know that lots of people have been rather upset by your replies. Personally, I find your writing very muddled and difficult to read. Why not make use of the spell checker (this reply box has one), capitalise your I's, and divide your writing into paragraphs? Try to make your points politely, even if you don't agree with people. Though this is an informal forum, it is full of real people who can only derive their perceptions of you from your writing .
