Information on normal and acceptable target blood glucose ranges for both diabetics and nondiabetics. Our chart considers factors such as age and whether or not a person is newly diagnosed.
Two types of hypoglycemia can occur in people who do not have diabetes: reactive (postprandial, or after meals) and fasting (postabsorptive). Reactive hypoglycemia is not usually related to any underlying disease; fasting hypoglycemia often is.

Defeating Diabetes: This books has detailed dietary and nutrition information to empower readers. Because diet and lifestyle factors are the primary causes of Type 2 diabetes, most Type 2's can control their diabetes completely.
Normoglycemia (Normal Blood Glucose) print normal & target ranges
Mini Site Index
The American Diabetes Association sets certain guidelines for normal and abnormal blood glucose levels (appearing at the bottom of this article). However, as a person with diabetes, your doctor may set different ranges for you. Young children may have slightly higher target ranges than stable adults. And those starting out on insulin pump therapy or are newly diagnosed with diabetes may initially have higher target ranges to help avoid hypoglycemia during the initial phase of insulin pumping.
The following chart takes into consideration some of the possibilities that may alter target ranges. The ranges given are intended for general purposes only and not as a diagnostic tool, or, for you to change your own diabetes care plan. It is important that you know and understand the target ranges that your doctor sets specifically for managing your own diabetes.
Normal and Target Blood Glucose Ranges in mg/dL for Diabetics
(1) People that are newly diagnosed or just beginning a new type of therapy (such as insulin pumping or going from conventional insulin therapy to intensive insulin therapy) may have slightly higher target ranges set for a certain period of time. This is done to help avoid dangerous episodes of hypoglycemia (low blood glucose) while medication dose or method of delivery is being adjusted. Be sure to keep in close contact with your physician whenever your diabetes care plan changes.
What are normal and target blood glucose ranges?
The following general guidelines for normal blood glucose ranges in nondiabetics* are from the American Diabetes Association. However, there are variations to these guidelines. For example, young children, those who are newly diagnosed, or are beginning insulin pump therapy may have slightly different target ranges.
Morning Fasting Blood Glucose
What if you are not in a "normal" range, but not in a "diabetic" range?
Blood glucose levels higher than normal, but lower than diabetic ranges, classify a person as having impaired glucose tolerance. To see how a person reacts to a glucose load an oral glucose tolerance test (OGTT) may be given to check blood glucose levels 2 hours after being given 75 grams of glucose to drink.
Oral Glucose Tolerance Test Ranges
Both IFG and impaired glucose tolerance (IGT) are associated with an increase risk in developing type 2 diabetes and lifestyle changes, including weight loss and an exercise program, as well as possible oral medications such as Glucophage are sometimes indicated.
