Why Test Blood Sugar Levels
If you take certain medication, like insulin or sulphonylureas, checking your blood sugars is a vital part of living with diabetes. It can help you work out when you need to take more medication, when you need to eat something or for when you want to get up and move around more.
Routine checks can help you know when you might be starting to go too low or too high . Its a way of getting to know your body and how it works. It can help you and your healthcare team spot patterns too. Do you write your results down? You might find that helpful.
But importantly, it will help you stay healthy and prevent serious diabetes complications now and in the future. By complications, we mean serious problems in places like your feet and your eyes. This happens because too much sugar in the blood damages your blood vessels, making it harder for blood to flow around your body. This can lead to very serious problems like sight loss and needing an amputation.
The higher your blood sugar levels are and the longer theyre high for, the more at risk you are.

- Glucose range before eating: 80â130 mg/dL or 4.4â7.2 mmol/L
- Glucose range 1â2 hours after eating: < 140 mg/dL or 7.8 mmol/L
For diabetics, average blood sugar ranges are:

Diagnosing Prediabetes Type 2 And Type 1 Diabetes
Depending on which country or medical organization you ask, the qualifying numbers for normal versus prediabetes versus diagnosed type 1 or type 2 diabetes can vary slightly. The following blood sugar and A1c the general results are used to diagnosed prediabetes and diabetes according to sources including the American Diabetes Association and Diabetes UK:
- HbA1c: 5.7 to 6.4 percent
- Fasting: 100 to 125 mg/dL
- 2 hours after a meal: 140 mg/dL to 199 mg/dL
Type 1 or 2 diabetes
- HbA1c: 6.5 percent or higher
- Fasting: 126 mg/dL or higher
- 2 hours after a meal: 200 mg/dL or higher
Please note: Type 1 diabetes tends to develop very quickly which means that by the time symptoms are felt, blood sugar levels are generally well above 200 mg/dL all the time. For many, symptoms come on so quickly they are dismissed as the lingering flu or another seemingly ordinary virus.
By the time blood sugar levels are tested, many newly diagnosed type 1 patients will see levels above 400 mg/dL or higher. If you do suspect that you or a loved-one has type 1 diabetes, visit your primary care or urgent care immediately and ask for a urine test to measure ketones in addition to testing blood sugar levels and A1c.

Diabetes complications include nerve damage, kidney disease, heart disease, or heart attacks.
If you see a healthcare provider about your blood sugar levels, be prepared to answer questions about risk factors like what you eat, how much you exercise, and about your family history. Some healthcare providers may want to take a blood sample to test your blood sugar levels. They may also order an A1C test, which is a blood test that measures blood sugar levels over several months. You may have to fast eight hours beforehand to get accurate test results, so its always a good idea to check before your appointment.

What Is Normal Blood Glucose
There is no one blood glucose level that defines a person as normal. The table of blood glucose levels below gives the appropriate values at different times and in different states, according to the American Diabetes Association. For example, insulin-dependent diabetics often use an upper limit of 7 mmol/L or 140 mg/dL, while non-insulin-dependent diabetics may aim for less than 6 mmol/L or 108 mg/DL.
The blood glucose levels range between less than 100-180 mg/dL for adults from 20 years or older. Depending on your age this may vary.
- Fasting: Less than 5.6 mmol/L or 100 mg/DL
- Before meal: 3.9-7.2 mmol/L or 70-130 mg/DL
- 1-2 hours after eating: Less than 10 mmol/L or 180 mg/DL
- Bedtime: 5.6-7.8 mmol/L or 100-140 mg/DL
Be aware that the above numbers might be different for everyone depending on your doctor’s recommendations.

Do You Have To Fast For An A1c Blood Test
Unlike the fasting plasma glucose and the OGTT tests, there is no need to fast before having the A1C test. If A1C test results indicate a person has or might have diabetes, a healthcare provider might suggest one of these tests to confirm the results. Another test, the random plasma glucose test, which does not require fasting, can also be used. If the results are borderline or if the results of the different tests do not match, a doctor might suggest repeating the test in several weeks or months.
Remedies For Low Blood Sugar Levels
If you experience any of the low sugar symptoms, immediately test your blood glucose levels. For levels between 60 to 80 mg/dL, consume 15 grams of fast-acting carbs. Repeat the test after 15 minutes and eat till sugar levels settle to normal.
But if the levels are below 50 mg/dL and if the patient is conscious and able to eat, give 15 gm. of fast-acting carbs. But if the patient is unable to speak, dont give anything to eat. Call emergency services immediately. If possible, administer glucagon via injection.
