Blood Sugar Level Chart for Diabetic Patients

Diabetes is a disease which can at times have no visible symptoms and it gets difficult to diagnose the disease in such cases. However, a simple ‘Blood Test’ done to test the blood sugar level can help in effective diagnosis of Diabetes. Blood sugar levels for diabetic patients are higher than the normal blood sugar level in humans. To know whether your blood sugar level can be termed as Diabetes or Prediabetes, you need to have an understanding of the different levels of sugar in blood which you will learn below.

What is Blood Sugar Level?

We all have a certain amount of sugar in our bodies and the quantity of blood sugar or glucose in blood is known as the blood sugar level. If these levels rise, a person may suffer from Diabetes. There are various tests to measure these levels and are used for diagnosis of Diabetes. Some tests are conducted after eating whereas some of them are conducted before eating and the blood sugar level for both of them differs.

National Institute of Clinical Excellence (NICE) recommended target blood glucose level ranges

Target Levels
by Type
Upon waking Before meals
(pre prandial)
At least 90 minutes after meals
(post prandial)
Non-diabetic** 4.0 to 5.9 mmol/L under 7.8 mmol/L
Type 2 diabetes 4 to 7 mmol/L under 8.5 mmol/L
Type 1 diabetes 5 to 7 mmol/L 4 to 7 mmol/L 5 to 9 mmol/L
Children w/ type 1 diabetes 4 to 7 mmol/L 4 to 7 mmol/L 5 to 9 mmol/L

**The non-diabetic figures are provided for information but are not part of National Institute of Clinical Excellence (NICE) guidelines.

Blood Sugar Level of Diabetic Patients

After a certain limit, the level of blood sugar is known as the diabetic blood sugar level which would mean that you are suffering from Diabetes. The blood glucose level differs as per age as well as gender along with other conditions such as pregnancy. Let’s see how the range differs for each type of person based on the Diabetes blood sugar levels chart.

Plasma glucose test Normal Prediabetes Diabetes
Random Below 11.1 mmol/l
Below 200 mg/dl
N/A 11.1 mmol/l or more
200 mg/dl or more
Fasting Below 6.1 mmol/l
Below 108 mg/dl
6.1 to 6.9 mmol/l
108 to 125 mg/dl
7.0 mmol/l or more
126 mg/dl or more
2 hour post-prandial Below 7.8 mmol/l
Below 140 mg/dl
7.8 to 11.0 mmol/l
140 to 199 mg/dl
11.1 mmol/l or more
200 mg/dl or more


There are many tests to determine the blood sugar levels in kids. The most common test that doctors recommend is the ‘Fasting Blood Sugar Test’. If your child has a 100 mg/dl of blood sugar level in a ‘Fasting Blood Test’ then he or she is perfectly fine and is in the normal range. But if it exceeds from that level and is below 125 mg/dl, your child is suffering from Prediabetes.

Finally, if your child has a blood sugar level of more than 126 mg/dl, he or she is suffering from Diabetes. These levels can be different for various tests and you must refer to your doctor to know whether your child is suffering from Diabetes.


Adults have a slightly higher range of normal blood sugar level as per the blood glucose chart. The normal range of blood sugar as per the ‘Fasting Blood Sugar Test’ is below 108 mg/dl. Anything which is significantly lower than this level is considered to be a low blood sugar range.

The range between 108 mg/dl to 125 mg/dl is said to be a state of Prediabetes which is an onset for the Type 2 Diabetes. The high blood sugar range for adults is above 126 mg/dl which is termed as Diabetes. You must constantly keep your blood sugar level in check by frequently referring to the blood sugar level chart.


During pregnancy, a woman’s body goes through a lot of vital changes and the blood sugar level is impacted to a certain level. However, the normal blood sugar range for pregnant women without Diabetes is from 69 mg/dl to 75 mg/dl on a ‘Fasting Blood Sugar Test’.

Diabetes Blood Sugar Levels Chart for Pregnant Women

Target Blood Glucose Numbers (mg/dL) for Women with Gestational Diabetes
Time of Day Targets
Before meals and when you wake up 95 or lower
1 hour after eating 140 or lower
2 hours after eating 120 or lower

For women who are suffering from Gestational Diabetes, the blood sugar level is higher than 95 mg/dl. Multiple blood tests are required during the tenure of pregnancy to diagnose Gestational Diabetes.
