Blood Sugar Level Chart

It is important to know the desired blood glucose numbers when we want to control our blood sugar.  Here we will look at the normal and diabetic blood sugar ranges after fasting, 1 to 2 hours after a meal, and the HbA1c.

Before we look at the blood sugar level chart, we will take a look at what is considered a normal blood sugar reading.

What is a Normal Blood Sugar Level?

We will begin by looking at the fasting blood sugar level.

Fasting Blood Sugar Level

A fasting blood sugar reading is the one you take first thing in the morning before eating or drinking.  This has a range of 70 – 99 mg/dl (3.9 – 5.5 mmol/L).

A fasting blood sugar reading is taking a look at the amount of sugar/glucose present in our blood.  Please note that fasting blood sugar could be taken after 8 hours of avoiding all foods and drinks.  We are permitted to drink water during this time.

So what happens when we eat?  Let us take a look at what is considered the ideal 2 hours after a meal.

Two (2) Hours After a Meal Blood Sugar Level

Please look below to see what our blood sugar reading should be 1 to 2 hours after we eat.

Two (2) hours after we eat our blood sugar should be lower than 140 mg/dl (7.8 mmol/L).

This reading is essential, especially for people with diabetes. It is this reading that guides our eating as it tells us how different foods affect our bodies.  For those without this lifestyle illness, you could avoid later troubles by occasionally taking a look at how different foods affect your blood sugar level.

Let us turn our attention to the test done by the lab, which is usually the first time that most people discover that they are diabetic.

HbA1c Blood Sugar Level

When we go to the doctor and report that we are urinating a lot, especially at nights, thirsty all the time and our mouth is dry, we are tired, and generally too weak to do our chores, or our eyes are blurry, it sends a red flag to our doctor.

This is when we are sent to the laboratory to do the Hba1c test.  This is an examination of the blood to look at the average blood sugar levels over a 3 months period.

Our HbA1c should be less than 5.7%.  The higher it gets, then we know that we are diabetic and a lifestyle change is evident to control diabetes.

Kindly note that because this test takes an average over 3 months, it is not necessary to fast prior to doing the HbA1c.

Since our aim is to control blood sugar, then let us now look at the chart to compare the normal blood sugar ranges with that of a person considered to be diabetic.

What is the Blood Sugar Level for a Diabetic?

Just like we did above, we will now take a look at the fasting blood sugar, the post-meal blood sugar readings (1-2 hours after a meal), and the HbA1c readings for a diabetic.  Let us begin with the recommended fasting blood sugar level.

Fasting Blood Sugar for the Diabetic

Please be reminded that this is the reading after a fast.

For diabetics, the recommended fasting blood sugar range is 80-130 mg/dl (4.4-7.2 mmol/L).

Again this is the reading when we get up in the morning before we consume food.  It could also be after 8 hours fast where water is permitted.

Take a look below for what we should expect after a meal.

Two (2) Hours After a Meal Blood Sugar Level for the Diabetic

Let us see what our numbers should look like 1 to 2 hours after a meal.  Please bear in mind that what we eat will change our blood sugar reading.

One (1) to two (2) hours after a meal a diabetic should see a blood sugar reading of below 180 mg/dl (10 mmol/L).

Please note that when we are taking medication for diabetes we could still see this reading (high).  The secret is in our lifestyle.  Eating whole foods, especially those with little carbs, and exercising.

It is now time to take a look at what to expect when we go to the laboratory and do the HbA1c test.

HbA1c Blood Sugar Level for the Diabetic

Just a reminder that this type of test is done in the laboratory and does not require the patient to fast.

The HbA1c for diabetics is expected to be below 7.0%.

Let us take a look at the chart below which is a graphical representation of the information given above.

Comparative Blood Sugar Chart

This chart will show the recommended blood sugar levels for non-diabetics and diabetics.  It will show three types:

  • Fasting blood sugar levels
  • One to two hours after a meal blood sugar levels
  • HbA1c

Please take some time to examine the chart below.
