Whats Considered A Normal Glucose Level
Your doctor will likely test your blood glucose levels as a screening test for diabetes during a standard yearly check-up. Additionally, many people track their glucose at home with an over-the-counter finger-prick test. When you check blood glucose , either at a doctors office or with a home finger stick glucose monitor, the results are in milligrams of glucose per deciliter of blood.
One of the most common glucose measurements is fasting plasma glucose or fasting blood glucose , and its found by checking blood glucose levels after not having any calories at least eight hours before the test. According to the American Diabetes Association , people can be classified into three categories depending on their fasting plasma glucose levels: normal, prediabetes, and diabetes. To be considered normal, fasting glucose must be under 100 mg/dl.
Of note, CGM devices measure interstitial glucose levels compared to blood/plasma glucose levels measured in the FPG tests. While interstitial glucose and blood/plasma glucose levels correlate highly, they are not precisely the same, and diagnoses are not made from interstitial measurements.
Below is a summary overview of data about 24-hour glucose trends in nondiabetic individuals wearing CGM to gain a better understanding of whats normal.
What Are The Target Ranges
Blood glucose targets are individualized based on:
- duration of diabetes
- conditions a person may have
- cardiovascular disease or diabetes complications
- hypoglycemia unawareness
- individual patient considerations
The American Diabetes Association suggests the following targets for most nonpregnant adults with diabetes. A1C targets differ based on age and health. Also, more or less stringent glycemic goals may be appropriate for each individual.
- A1C: Less than 7%A1C may also be reported as eAG: Less than 154 mg/dL
- Before a meal : 80130 mg/dL
- 1-2 hours after beginning of the meal *: Less than 180 mg/dL
Diabetes Is Diagnosed By Any One Of The Following:
Sometimes you may have symptoms of fatigue, excessive urination or thirst, or unplanned weight loss. However, often people have no symptoms of high blood glucose and find a diabetes diagnosis surprising.

Fasting Blood Glucose Level Test Preparation
What should you do if your doctor orders a fasting blood sugar test? The preparation is the same as when you take a fasting test for cholesterol. First, be sure to find out if you need to schedule an appointment for your test . Ask your doctor what time is best to take it.
- Schedule your test if necessary
- Ask your doctor if you need to change any of the medications you take on the morning of the test
- If you normally drink coffee or have caffeine, ask your doctor if that is okay. It may not be, since it affects blood sugar levels
- Fast for at least 8 hours before your test. Usually, an overnight fast is most convenient
- You can drink water
How Can I Treat Low Blood Sugar
If youve had low blood sugar without feeling or noticing symptoms , you may need to check your blood sugar more often to see if its low and treat it. Driving with low blood sugar can be dangerous, so be sure to check your blood sugar before you get behind the wheel.
Carry supplies for treating low blood sugar with you. If you feel shaky, sweaty, or very hungry or have other symptoms, check your blood sugar. Even if you dont have symptoms but think you may have low blood sugar, check it. If your blood sugar is lower than 70 mg/dL, do one of the following immediately:
- Take four glucose tablets.
- Drink four ounces of fruit juice.
- Drink four ounces of regular soda, not diet soda.
- Eat four pieces of hard candy.
Wait for 15 minutes and then check your blood sugar again. Do one of the above treatments again until your blood sugar is 70 mg/dL or above and eat a snack if your next meal is an hour or more away. If you have problems with low blood sugar, ask your doctor if your treatment plan needs to be changed.

Blood Sugar Levels: What’s Normal What’s Not And How To Measure Them
What blood glucose levels mean and what range is healthy.
Sugar can lead to high blood sugar and contributes to the development of diabetes.
We all want to keep track of our health in every way we can — you may weigh yourself daily, measure your waist-to-hip ratio, keep track of your blood pressure or monitor your resting heart rate. But how close of an eye do you keep on your blood sugar?
People with diabetes are all too familiar with their blood sugar levels, but the rest of us might not even think about them. However, consistently high blood sugar levels can coexist with Type 2 diabetes and cause serious health conditions like kidney disease, nerve problems or stroke.

What Should I Do If My Blood Sugar Gets Too Low
Low blood sugar is also called hypoglycemia . It means your blood sugar level drops below 70. Having low blood sugar is dangerous and needs to be treated right away. Anyone with diabetes can have low blood sugar. You have a greater chance of having low blood sugar if you take insulin or certain pills for diabetes.
Carry supplies for treating low blood sugar with you. If you feel shaky, sweaty, or very hungry, check your blood sugar. Even if you feel none of these things, but think you may have low blood sugar, check it.
If your meter shows that your blood sugar is lower than 70, do one of the following things right away:
- chew 4 glucose tablets
- drink 4 ounces of fruit juice
- drink 4 ounces of regular soda, not diet soda or
- chew 4 pieces of hard candy
After taking one of these treatments, wait for 15 minutes, then check your blood sugar again. Repeat these steps until your blood sugar is 70 or above. After your blood sugar gets back up to 70 or more, eat a snack if your next meal is 1 hour or more away.
If you often have low blood sugar, check your blood sugar before driving and treat it if it is low.
What You Can Drink With Meals
Add a low-calorie, low-sugar drink or choose water. Proper hydration is essential to helping your body remove excess sugar.
Some drinks that are good for keeping your blood sugar level low include:
- Unsweetened tea
- Unsweetened coffee
- Sparkling water or club soda
- Flavored water or sparkling water without added sugar
- Diet soda or other diet drinks

Dont Rely On Supplements Or Vitamins
Theres no shortcut to maintaining good blood sugars. A supplement or vitamin alone will not give you healthy blood sugar levels and they can interact negatively with other medications. Speak to your healthcare provider and perhaps ask for a referral for a dietitian who specializes in blood sugar control before incorporating dietary supplements, shakes, or vitamins to achieve blood sugar control.

Normal Blood Sugar Levels Chart
Every substance present in our body has an optimum level. Above or below that specific range, that particular substance is harmful to our health. And so is sugar. There is a certain range of blood sugar which is considered as standard for almost all age. However, there might be some changes in the level considering different factors like age and other co-morbidities. Lets look at the chart:
|2 hours after the meal||< 140 mg/dl|
Sometimes, random blood is also taken. In this case, the glucose level of 200 mg/dl is considered a diabetic condition.
Going through the chart you will notice certain terms regarding blood sugar which you need to understand in order to evaluate your own glucose level. So, I will just give a small brief regarding those:
- Fasting blood glucose: Here, blood sugar is tested after abstaining from food and drink for at least 8 hours.
- Postprandial blood sugar:In this case, blood sugar is tested 2 hours after a meal to access if its at the optimum level after having a meal or not.
- Random blood glucose: Blood is tested at any time of the day.
- HbA1c: It refers to a blood test which is done to evaluate the average level of blood glucose over the past 3 months. HbA1c is also known as glycosylated haemoglobin or A1C. Moreover, fasting is not required before carrying out the test.
Is Hyperglycaemia Serious
The aim of diabetes treatment is to keep blood sugar levels as near to normal as possible.
But if you have diabetes, no matter how careful you are, you’re likely to experience hyperglycaemia at some point.
It’s important to be able to recognise and treat hyperglycaemia, as it can lead to serious health problems if left untreated.
Occasional mild episodes are not usually a cause for concern and can be treated quite easily or may return to normal on their own.
But hyperglycaemia can be potentially dangerous if blood sugar levels become very high or stay high for long periods.
Very high blood sugar levels can cause life-threatening complications, such as:
- diabetic ketoacidosis a condition caused by the body needing to break down fat as a source of energy, which can lead to a diabetic coma this tends to affect people with type 1 diabetes
- hyperosmolar hyperglycaemic state severe dehydration caused by the body trying to get rid of excess sugar this tends to affect people with type 2 diabetes
Regularly having high blood sugar levels for long periods of time can result in permanent damage to parts of the body such as the eyes, nerves, kidneys and blood vessels.
If you experience hyperglycaemia regularly, speak to your doctor or diabetes care team.
You may need to change your treatment or lifestyle to keep your blood sugar levels within a healthy range.

What Is Blood Sugar
When you eat, the carbohydrate in your food is broken down into a usable form of energy called glucose. Glucose also known as sugar enters the bloodstream and a hormone called insulin helps move it into our cells.
This process lowers the amount of glucose in the bloodstream. When this process works efficiently, your muscles and organs have the fuel they need without there being too much glucose remaining in the blood.
When Should I Check My Blood Sugar
How often you check your blood sugar depends on the type of diabetes you have and if you take any diabetes medicines.
Typical times to check your blood sugar include:
- When you first wake up, before you eat or drink anything.
- Before a meal.
- Two hours after a meal.
- At bedtime.
If you have type 1 diabetes, have type 2 diabetes and take insulin, or often have low blood sugar, your doctor may want you to check your blood sugar more often, such as before and after youre physically active.

Eat Foods With A Low To Medium Gi Score
Look for foods with a low to medium glycemic index score. These are foods that your body absorbs slowly and decrease spikes in blood sugar. Some people pair low and high GI foods in order to balance their blood sugar. Another way to think about foods that lower blood glucose are ones that do not provide fast energy but give you more energy over a longer period of time. Foods with a low glycemic index have many health benefits besides their effects on blood sugar, so eating a diet high in protein, fatty acids, and fiber will benefit your whole family, not just those actively trying to achieve glycemic control.
What Should I Aim For
Effective management of diabetes is all about aiming for a careful balance between the foods you eat, how active you are and the medication you take for your diabetes. Because this is a delicate balance, it can be quite difficult to achieve the best possible blood glucose management all the time.
The ranges will vary depending on the individual and an individuals circumstances. While it is important to keep your blood glucose levels as close to the target range of target range between 4 to 6 mmol/L as possible to prevent complications, it is equally important to check with your doctor or Credentialled Diabetes Educator for the range of blood glucose levels that are right and safe for you. Therefore the following information should be treated only as a general guide.

How To Test For Ketones
You can use a urine test strip or blood ketone meter and ketone test strip to test for ketones at home. Testing either urine or blood is important, but when possible, a blood test is preferred because it gives you and your care team more precise information about your ketone levels. Because urine may have been in the bladder for some time, the results from these tests may show levels that are either higher or lower than the ketone levels that are actually circulating in your body. It is also very important to know that urine test trips degrade over time, so if you are using this method, you need to look at expiration dates carefully.
Your diabetes care team can give you specific directions about when you should check for ketones, but in general, you should check for them when your blood glucose is 240 mg/dL or higher. You should also check for ketones if you notice any of the DKA symptoms listed above or if you are sick it is possible to have ketones while your blood glucose levels are within range .
At-home urine test strips will change color to show the level of ketones in the urine. They typically report results as negative, trace, small, moderate or large. Blood ketone meters will provide a number that indicates the ketone levels. The following ranges are generally used:
How Food Affects Blood Sugar
When you eat food, your body breaks it down into essential parts:
- Vitamins and minerals
All parts are necessary in a healthy diet, but the three types of carbohydrates are particularly important when it comes to your blood glucose level. While the general rule is that the more carbohydrates you eat, the higher your blood sugar level, not all three types of carbohydrates convert to blood sugar at the same rate.
The foods that fit into each carb category include:
- Starches, or complex carbohydrates: Starchy vegetables, dried beans, and grains
- Sugars: Fruits, baked goods, beverages, and processed food items like cereals or granola bars
- Fiber: Whole wheat products, chickpeas, lentils, berries, pears, and brussels sprouts
The glycemic index helps you find out which foods can increase or help decrease blood sugar levels. Based on a scale ranging from 0 to 100, high-indexed foods are rapidly digested, absorbed, and metabolized, resulting in marked fluctuations in blood sugar levels, while low-indexed foods produce smaller fluctuations in your blood glucose.
The American Diabetes Association advises adding lean sources of protein and heart-healthy fats to help reduce the overall glycemic impact of a meal or snack.
