What Is The Normal Blood Sugar Level For Adults
Blood glucose levels can vary between different age groups and at different times of the day. It can be challenging to figure this all out on your own, especially if you’ve never monitored your blood sugar levels.
Optimal Glucose Range: It Is Important For Adults To Maintain Normal Blood Sugar Levels
Read on to learn what is “normal,” and check out the blood sugar charts to learn more about the normal target range for blood sugar levels based on your age.
Before we start talking about numbers, it’s important to note that “normal” blood sugar levels vary based on many factors. A great way to learn more about what your levels mean for your health goals is to contact a qualified health care professional.
“Your body breaks down carbohydrates into sugar, which is your body’s main source of energy. The pancreas then secretes insulin to transport the sugar into your cells, where it is converted into energy. Glucose can also be stored as glycogen in the liver and muscles or as fat. Insulin and glucagon, along with other hormones, help control the amount of glucose in your blood.” – Heather Davis, MS, RDN, LDN
To learn more about how the body regulates glucose balance, see our article on glucose homeostasis. Remember, it is normal for glucose levels to fluctuate to some extent. Blood sugar levels are influenced by many factors, including:
How To Monitor Your Blood Sugar Levels: A Guide
Normal glucose values are often listed as a range to help capture any normal fluctuations that may occur within that range. Additionally, for those who may have health conditions such as prediabetes or diabetes (which is characterized by some degree of insulin resistance), normal glucose may be wider or lighter.
According to the National Children’s Hospital, non-diabetic children between the ages of 6-12 should have a normal glucose reading that looks like this:
Parents or caregivers usually won’t check a child’s glucose throughout the day unless they have a medical condition like type 1 diabetes. However, it can help to know what is healthy.
In children with diabetes, the amount of glucose in the blood will fluctuate from when they wake up, based on their activity levels, and before they go to bed at night.
Normal Glucose Levels Chart & Example
It is important to remember that despite all this, recommendations suggest that blood sugar levels should remain between 80-180 mg/dL throughout the day.
There are no guidelines set by the American Diabetes Association for normal blood glucose levels in young adults without diabetes. You should always consult your doctor for specific guidance. The Mayo Clinic recommends targeting similar guidelines for healthy children/adults without diabetes, to keep blood sugar between 70-140 mg/dL.
For new diabetics, it’s a good idea to consult your doctor for specific guidance. Some research on teenagers with type 1 diabetes recommends aiming for blood glucose levels between 70-150 mg/dL throughout the day.
Most research on normal glucose levels has focused on adults. Although you may notice that different labs may have different reference ranges, research shows that the optimal fasting glucose to reduce the risk of prediabetes may be between 70-90 mg/dL in adults without diabetes.
Defining Normal A1c Levels
Research also shows that fasting glucose levels above 90 can lead to a greater risk of heart disease.
There are many factors that can contribute to a high fasting blood glucose value. It is important to pay attention to things like these:
It may also help to monitor your alcohol intake, monitor any supplements you take, and monitor your overall physical activity and weight. Working one-on-one with a qualified health professional, including a registered dietitian or nutritionist, can help you make sense of some of these patterns and how they may affect your overall health.
Of course, the expected glucose ranges for adults with diabetes will differ from the target ranges for adults without diabetes. The American Diabetes Association also recommends different glucose levels for healthy adults, adults with prediabetes, and adults with diabetes. Healthy adults without diabetes should keep their blood glucose between 70-140 mg/dL.
Normal Blood Sugar Levels Chart & Example
According to the International Diabetes Federation (IDF) guidelines, adults with healthy glucose metabolism should stay below 140 mg/dL after meals. Healthy adults with normal glucose tolerance have been shown to stay below 140 mg/dL between 95-99 percent of the time.
Levels above 160 mg/dL may be problematic. Monitoring your glucose over time under the guidance of a qualified healthcare professional can help you assess your risk for conditions such as prediabetes and diabetes. Remember, most healthy people will see a glucose peak within 30 minutes of eating.
Wondering where prediabetes fits into all of this? The ADA classifies prediabetic fasting glucose levels as greater than 100 mg/dL and up to 125 mg/dL and two-hour postprandial levels between 140-199 mg/dL. It is usually detected by an oral glucose tolerance test. An A1C between 5.7-6.4 percent is considered prediabetes by the ADA.
Diabetes is diagnosed after a double fasting glucose test of more than 125 mg/dL or a two-hour reading of more than 200 mg/dL after an oral glucose tolerance test.
What Are The Signs Of High And Low Blood Sugar?
Additionally, an A1C greater than 6.5 percent is considered the level of diabetes by the ADA. Diabetes can also be diagnosed if a random blood sugar test at any time of the day is over 200 mg/dL.
Let’s spend a minute discussing average rates for adults over 65. Those without diabetes can be kept in the same glucose range as healthy young adults, which is keeping glucose between 70-140 mg/dL during the day.
In older adults with diabetes and comorbidities or severe symptoms of diabetes such as neuropathy, kidney damage, or retinopathy, the recommended glucose limit and A1C values may be mild. It will all depend on how much damage has been done to the pancreas.
Although there are ways to track, monitor, and determine if you have high blood sugar levels, you may not always know when you are experiencing it. Usually, there are no warning signs until your levels rise significantly above the expected range.
Diabetes Mellitus: Know Your Fasting, Post Prandial, Hba1c Numbers
For example, adults with prediabetes may not realize they have the condition based on symptoms alone. However, here are some classic symptoms of blood sugar that
It is easy that these symptoms are related to other causes, some of which seem to be a habit such as feeling thirsty or having a slight headache! This is where wearing a continuous glucose monitor (CGM) can be very important.
You may usually be able to connect these symptoms to blood glucose spikes that occur throughout the day when using a CGM. It is best to work with your doctor to help make this connection.
There are many ways to deal with high glucose readings that are effective and can be done every day.
Hypoglycemia Or Low Blood Sugar Level: Causes, Symptoms, And Management
Here are a few helpful lifestyle change tips from nutritionist Liz McKinney, MS, CNS, LDN:
Blood sugar monitoring is not just about learning more about high glucose levels. There is also a chance that they will sink! When blood sugar levels fall below 70 mg/dL, it is known as hypoglycemia.
When blood sugar drops below 70, accompanied by any of the common symptoms mentioned so far, it may be necessary to work on increasing it. Another way to do this is to eat 15 grams of fast-absorbing carbs (like apple juice or a glucose tablet), and wait 15 minutes for your blood sugar to rise.
Once your glucose is back in the normal range, it can help to eat protein- or fiber-rich foods to prevent future dips. nutritionist Liz McKinney, MS, CNS, LDN has a helpful suggestion!

“I suggest unsweetened Greek yogurt with berries or one to two hard-boiled eggs with a sliced avocado on a piece of whole wheat bread, it’s a great way to help with these conditions.”
If you’re eating a low-carb diet, seeing your glucose dip <70 may not be a cause for concern. This is because your body may have become accustomed to lowering the basal glucose. In this case, it is important to be aware of any symptoms and consider talking to your doctor to help you determine the right limits for your body.
Your blood sugar levels can have a big impact on how your body feels and functions. This is why stable glucose levels can be an important factor in supporting overall health.
With , you’ll be able to track your glucose levels over time using a CGM, so you can make lifestyle choices that support a healthy lifestyle.
