Hi

I am unsure as to what the question is.

According to SA guidelines, a fasting laboratory glucose (done in the morning after fasting for 8 hours) is considered normal if it is less than 110, pre-diabetes if it is between 110 and 126, and diabetes if it is 126 or more. Normally we would want two abnormal results, or one abnormal result with associated symptoms like tiredness, weight loss, drinking lots of water and passing too much urine. The other way to test glucose is to do a glucose tolerance test where you go to the lab fasting and they give one 75grams of glucose to drink in water and then test your glucose levels after 2 hours. The cut off for diabetes is a level of 200 or higher at 2 hours and normal is less than 140. Between these two levels is considered pre- diabetes. Some patients will be normal on one test and abnormal on another, so sometimes we may do  both. We don’t normally use the fingerprick test, as the levels are a bit more variable. If you are pre-diabetic, then Type 2 diabetes can be prevented or delayed, and trials done in high risk patients have shown that by losing 4 kg's in 4 years, one can reduce their chances of getting diabetes by 58%. Most trials used a low fat, high fiber, low GI diet with exercise, but potentially a low carb diet would work as well. A Mediterranean diet has also been shown to be useful. Losing weight is always hard. The best way is to cut down on total calories, more so than the type of calories, for your body can only burn so many calories a day, and if you eat less than this, then weight loss will occur.  Exercise requirements for weight loss are a lot and entail about 60-90 minutes every day.
