Glucose intolerance is when the body does not utilise the glucose in your body properly and the fasting blood glucose level is above 6.0 mmol/L or your blood glucose level is over 7.8 mmol/L 2 hours after consuming 75g of glucose.
At this stage, with life style changes and exercises, you can still avoid getting diabetes. You could say it is pre diabetes.
The symptoms of glucose intolerance can be those of hyperglycaemia and also tingling sensations.
The best way to find out if you are glucose intolerance is to ask your doctor to send you for a glucose test. My doctor sent me for one many years ago when I kept complaining about pins and needles sensations in my feet and the glucose test confirmed that I my body was intolerant to glucose. I knew I had something not right after I drank the glucose and then could not stop drinking water to quench my thirst.
Even though you recently tested negative for diabetes, you need to know the exact blood glucose levels. This will also depend on how you got tested. A finger prick test will only show the amount of glucose in the body at the time of doing the strip finger prick test.
An HbA1C blood test will show the percentage levels of glucose in your blood over a period of 9-12 weeks. The blood is renewed every 9-12 weeks and the glucose sticks to the old red corpuscles to give an average read out.
The fasting glucose test will show exactly how your body reacts to the glucose.
There is more specific information on the web on glucose intolerance if you want to know more about it, just type in "glucose intolerance" in the web bar.
In the UK an HbA1C blood test level of 6.9 mmol/L is now classed as having Type 2 diabetes.
Hope this helps.
What does it mean to be glucose intolerant?
Is that the same as diabetes?
When you say that you have been tested for diabetes and this is negative (great news), did they say whether you are glucose intolerant?
The other reasons for tingling in the legs can be referred from the lower spine or from your groin area if you have meralgia paraethetica (the tingling is in the outer thighs), or a knee problem. Tingling can also be caused if you have an infection or a virus, bad circulation, inflammation of the veins.
Do you take any vitamin supplements? You can overdose on some vitamins and that can cause sensations of tingling. Because your tingling is confined to your legs it is highly unlikely to be an overdose of multivitamins.
You will need to make an appointment to see your doctor to get further tests, xrays or imaging of your lower spine done.
