Monitoring Your Blood Sugar at Home

When monitoring your blood sugar with a glucometer, use this blood sugar level chart to make sure you're in the normal range.

Even if you're not diabetic or even pre-diabetic, you might want to check up on your blood sugar levels every now and again. This will help you determine your personal average range and help you spot a rising trend early, so you can quickly get to work lowering it before it gets too high.

I think it's interesting to use my own blood sugar level testing to double check information I've read. You can't believe everything you read, especially about healthy eating. You never know for sure what their source is or if they have some sort of hidden agenda.

Sometimes, when I read about foods that lower blood sugar, I'll eat some of that food, and then, check my blood sugar. It can be really eye-opening sometimes. It's interesting how differently different foods affect different people.

Try it some time. You might be surprised.

(Note: This chart is for children and non-pregnant adults. Pregnant women with gestational diabetes have different blood sugar level targets. Click here to go to the chart for gestational diabetes.)

Blood Sugar Level Chart for
Monitoring Blood Glucose with a Glucometer

  Normal Range
On Waking Up (fasting) 70-130 mg/dL (5.0–7.2 mmol/L)
Before Meals 70-130 mg/dL (5.0–7.2 mmol/L)
2 Hours After Eating 100-140 mg/dL (5.6-7.8 mmol/L)
Before Bed Time 100-140 mg/dL (5.6-7.8 mmol/L)

*Remember that low blood sugar levels can be just as dangerous as a high blood sugar level. If your blood sugar dips below 60 mg/dL, take steps recommended by your doctor to bring it back under control.

Tests for Diagnosing Diabetes
and the HbA1c Test

Your doctor uses one or more of these tests to diagnose diabetes:

  • Random Plasma Glucose test (also called Casual Plasma Glucose test)
  • Fasting Plasma Glucose test (FPG)
  • Oral Glucose Tolerance test (OGGT)

The chart below shows the normal, pre-diabetic, diabetic, and dangerous ranges for these three tests and the HbA1c test.

If you think you have diabetes, talk to your doctor about getting tested. If you've already had one of these tests, check your results on this chart.

Diabetes Tests and the HbA1c Test

  mg/dL mmol/L mg/dL mmol/L mg/dL mmol/L mg/dL mmol/L

Fasting Plasma Glucose (FPG) Test <100 <5.6 100-125 5.6-6.9 >125 >6.9 >150 >8.3
Oral Glucose Tolerance Test (OGGT) <140 <7.8 140-199 7.8-11.1 >200 >11.1 >250 >13.9
HbA1c <5.7% 5.7%-6.4% >6.4% >9%

Gestational Diabetes

During pregnancy - around week 24 - your care giver will use the Oral Glucose Tolerance test to screen for gestational diabetes. Many care givers have a Random/Casual Plasma Glucose test or a Fasting Plasma Glucose test done first and then the Oral Glucose Tolerance test if you fail the first one.

This chart shows the targets for the Oral Glucose Tolerance test. If you are above the normal range two or more times during the test, you have gestational diabetes.

Blood Sugar Level Chart for
Gestational Diabetes Testing

  Normal Range
Before Sugar Drink (fasting) <95 mg/dL (5.3 mmol/L)
1 Hour After Sugar Drink <180 mg/dL (10 mmol/L)
2 Hours After <155 mg/dL (8.6 mmol/L)
3 Hours After <140 mg/dL (7.8 mmol/L)

If you have gestational diabetes, use this chart when monitoring your blood sugar.

Blood Sugar Levels Conversion Charts

Blood Sugar Level Chart for
Converting A1c to Estimated Average Glucose (eAG)

Using Estimated Average Glucose (eAG), you can think of your HbA1c test results in more familiar terms, either mg/dL or mmol/L.

In case you're interested, here are the formulas to convert A1c to eAG:

eAG(mg/dl) = 28.7 × A1C(%) - 46.7
EAG(mmol/l) = 1.59 × A1C(%) - 2.59

If not, here's a quick reference chart for your convenience.

Free Blood Sugar Log

To help you keep track of your blood sugar levels, here's a free blood sugar log from the American Diabetes Association.

Also, you can track your numbers online through a free service called Diabetes 24/7.

Your blood sugar meter should have a memory feature that keeps track of your blood sugar results for you automatically. With most, you can also download your data directly to your computer to help you analyze results and spot trends.

How to Get a Free Blood Sugar Meter

If you need a new blood sugar meter, don't pay for it! Glucometer manufacturers make their money off the test strips, so they often give the meters away for free.

If you have insurance, call them first to see which glucometers/strips they cover.

Go to the manufacturer's website or call their customer service number, and ask if they have any free offers.

Ask your doctor or pharmacy if they have any free meters. Manufacturers often give medical professionals free meters to hand out to their patients.

How to Control Your Blood Sugar Naturally

If your blood sugar tends to be outside the normal range blood sugar levels, you likely are insulin resistant and on your way to (or already have) diabetes.

Insulin resistance and type 2 diabetes are completely preventable and reversible. Controlling your blood sugar takes diligence, but it is possible. Take these steps to start lowering your blood sugar today:

  1. Healthy Eating: With Type 2 diabetes, your unhealthy diet got you here, and a healthy diet can go a long way towards fixing it. Follow these healthy eating guidelines, and eat a low glycemic whole food diet.

    Choose foods that lower blood sugar like cinnamon, avocados, vegetables, nuts, and seeds (especially chia seeds). Eat fermented foods to get your probiotics and increase the good bacteria in your gut.

  2. Exercise: Start with weight training to strengthen your body and help you lose weight. High intensity weight training works best. Lift enough weight so that you can do only 8-10 repetitions before your muscles give out. When you can do more than 10 repetitions, increase your weights.

    As you get stronger, add some cardio. High intensity interval training works best.

    Round out your exercise program with a stretching routine, like yoga, to increase flexibility and reduce stress.

  3. Get your sun! ... but don't get sun burned. When you expose your skin to sunlight, it makes vitamin D. If you can't get sun on a daily basis, take a vitamin D3 supplement. Your vitamin D level should be 60-80 ng/ml. You'll have to get your vitamin D level tested to know what it is. Ask your doctor for the 25(OH)D test.

Strive to keep your blood sugar in the normal range on the blood sugar level chart the majority of the time to prevent (or reverse) insulin resistance and type 2 diabetes. A healthy blood sugar level can also help prevent

  • Heart disease,
  • Stroke,
  • Kidney disease,
  • Blindness,
  • Nerve problems,
  • Gum infections,
  • Amputation,
  • Heart attacks,
  • Hearing loss due to diabetes,
  • High blood pressure,
  • Cancer, and
  • Obesity.
