What Is The Normal Blood Sugar Range?
Question: what is the normal blood sugar range ? fasting,post pradial and random? my sugar levels in fasting is 105 to 108 and post prandial is 150... after 3 hours it settles down to 110 to 120. Am I diabetic ?
Brief Answer:
Further testing necessary
Detailed Answer:
Normal blood glucose levels are
65 to 99 mg/dl in the fasting state.
100 to 125 is considered Pre diabetic i.e. a risk factor for the development of type 2 diabetes. An alternative technical term for this condition is IFG (Impaired Fasting Glucose).
126 and above is tantamount to a a diagnosis of diabetes
Post prandial the blood glucose levels normally remain under 140. However the standardised way to assess this is through the 75 grams OGTT (Oral Glucose Tolerance Test).
2 hours after the glucose load, blood glucose levels are
Normal if less than 140
140 to 199 is Pre diabetes or IGT (Impaired Glucose Tolerance)
200 or more is sufficient to make a diagnosis of diabetes.
Random glucose levels of more than 200 with symptoms of high blood sugar such as increased thirst, urination, hunger and weight loss are also sufficient to make a diagnosis of diabetes.
So you seem to have both IFG and IGT. It is quite likely you have Pre diabetes. But to be certain whether or not you have diabetes, one needs to do either the OGTT or Glycosylated Hemoglobin (HbA1c) test.
This is because some people have fasting glucoses in the pre diabetic range but their 2 hour post glucose challenge readings or the HbA1c cutoffs meet criteria for diabetes
