What Are Normal Blood Glucose Levels For People With Diabetes

People with diabetes will often have higher blood sugar targets or âacceptableâ ranges than those without the condition, although these levels can also vary individually depending on a personâs treatment goals.

According to the American Diabetes Association, target blood sugar levels for people with diabetes are:

• Before eating: 80â130 mg/dL
• One to two hours after eating: < 180 mg/dL

Warning Signs Of High Blood Sugar

While there are ways to track, monitor, and determine whether you have high blood sugar, you may not always know when youâre experiencing it. Often, there are no warning signs until your levels rise much higher than the expected range.

For example, adults with prediabetes may not realize they have this condition based on symptoms alone. However, here are some classic symptoms of high blood sugar that may occur:

• Fatigue
• Anxiety
• Increased cravings

Itâs easy to attribute these symptoms to other causes, some as seemingly routine as feeling thirsty or getting a slight headache! Thatâs where wearing a continuous glucose monitor can be invaluable. You may often be able to connect these symptoms to blood glucose spiking throughout the day when youâre monitoring your levels with a CGM.

Blood Sugar Levels 2 Hours After Youve Eaten

Many foods have types of carbohydrates called starches and sugars. When you eat foods with these types of carbohydrates, your body breaks them down into glucose, which is a type of simple sugar, and releases the glucose into your bloodstream. Aside from glucose produced by your liver, food is the main source of plasma glucose.

Two hours after eating, your blood sugar levels rise. They rise more when you eat more carbohydrates, when you do not eat fiber, fat, or protein with your carbs, and when you eat certain types of carbohydrates, such as refined sugars and starches.

These are target values from The Joslin Diabetes Center, which include levels for people with diabetes:

What Is Low Blood Glucose

Low blood glucose, also called low blood sugar or hypoglycemia, occurs when the level of glucose in your blood drops below what is healthy for you. For many people with diabetes, this means a blood glucose reading lower than 70 milligrams per deciliter .1 Your number might be different, so check with your doctor or health care team to find out what blood glucose level is low for you.

Summary

Normal And Diabetic Blood Sugar Ranges

For the majority of healthy individuals, normal blood sugar levels are as follows:

• Between 4.0 to 5.4 mmol/L when fasting
• Up to 7.8 mmol/L 2 hours after eating

For people with diabetes, blood sugar level targets are as follows:

• Before meals : 4 to 7 mmol/L for people with type 1 or type 2 diabetes
• After meals : under 9 mmol/L for people with type 1 diabetes and under 8.5mmol/L for people with type 2 diabetes

What A1c Goal Should I Have

People will have different A1C targets, depending on their diabetes history and their general health. You should discuss your A1C target with your health care professional. Studies have shown that some people with diabetes can reduce the risk of diabetes complications by keeping A1C levels below 7 percent.

Managing blood glucose early in the course of diabetes may provide benefits for many years to come. However, an A1C level that is safe for one person may not be safe for another. For example, keeping an A1C level below 7 percent may not be safe if it leads to problems with hypoglycemia, also called low blood glucose.

Less strict blood glucose control, or an A1C between 7 and 8 percentor even higher in some circumstancesmay be appropriate in people who have

Glycosylated Hemoglobin Or Hemoglobin A1c

Reflects average blood sugar levels over the preceding 90-day period. Elevated levels are associated with prediabetes and diabetes. Individuals with diabetes have an increased risk of a cardiac event. A person with diabetes has the same risk for heart attack as a person without diabetes, who has experienced one heart attack, having a second heart attack. Aggressive global preventive risk reduction efforts, such as lower LDL targets, diet, exercise and blood pressure control, are recommended.

Goal values :

• A range of 5.7-6.4 percent indicates an increased risk for development of diabetes , and lifestyle interventions may be beneficial.
• A value equal or greater than 6.5 percent is considered diabetes.

Preparation

This test may be measured any time of the day without fasting.

Glycosylated hemoglobin is blood glucose attached to hemoglobin . This test is often called the “diabetes report card.” It reflects the average blood sugar for the two to three month period before the test.

To calculate the average blood glucose level from the HbA1C:

HbA1C level x 33.3 86 = average blood glucose level for the past 90 days. HbA1C can be helpful to track diabetes control over time.

People With Gestational Diabetes

Gestational diabetes can occur during pregnancy. Often, it is a temporary condition, but it can lead to pregnancy complications.

The American Diabetes Association recommends that people with a diagnosis of gestational diabetes aim for blood sugar levels similar to those for people without diabetes, although individual targets may vary.

The ADA offers the following as a guideline:

• kidneys
• blood vessels

A wide range of complications can also result, such as slow wound healing and frequent infections. Other possible complications include:

Normal Blood Sugar Levels For People Without Diabetes

Non-diabetic individuals should aim for blood glucose metrics in the following ranges:

• Fasting Glucose: 80-86 mg/dl
• Pre-Meal : 72-90 mg/dl
• Post-Meal Glucose Peak: 99.2 ± 10.5 to 137.2 ± 21.1 mg/dl
• Mean 24-Hour Glucose: 89-104 mg/dl
• A1C: 4-5.6%
• Time-in-Range: 90% of the day within 70-120 mg/dl

Every study into normal blood sugar levels for adults finds slightly different results, because every sample population is different. And metrics like the post-meal glucose peak, which indicates normal blood sugar levels after eating, can vary hugely depending on what you eat. But the ranges we give above take into account the conclusions of the most recent, reputable studies, like this study on continuous glucose monitoring in healthy individuals.

Tests For Gestational Diabetes

Gestational diabetes is diagnosed using blood tests. Youll probably be tested between 24 and 28 weeks of pregnancy. If your risk is higher for getting gestational diabetes , your doctor may test you earlier. Blood sugar thats higher than normal early in your pregnancy may indicate you have type 1 or type 2 diabetes rather than gestational diabetes.

Why Your Blood Sugar Level May Be Low

If blood sugar drops below 70 mg/dL, it is below normal levels. This can be caused by a variety of factors, such as:

• Not eating enough or missing a meal or snack
• Reducing the amount of carbohydrates you normally eat
• Alcohol consumption especially if youre drinking on an empty stomach
• Taking too much insulin or oral diabetes medication based on carbohydrates or activity levels
• Increased physical activity
• Side effects from medications

If you have diabetes, keep your blood glucose meter and sources of fast-acting glucose close by in case your blood sugar drops. This is especially important for people with hypoglycemia unawareness, which is a condition that causes symptoms of low blood sugar to go unnoticed.

Eating balanced meals and snacks at regular times throughout the day is a big part of maintaining normal blood glucose levels. Check out our article on meal planning for diabetes to better understand the three macronutrients where calories come from and which have the biggest effect on blood sugar.

Everyone will respond differently to certain factors, which is why its important to have individualized target glucose levels. To help you reach your target blood glucose goals, work with your healthcare provider to discuss modifications to your diet, physical activity, or medications, and alert them of other factors like a recent illness or stressful event.

Recommended Target Blood Glucose Level Ranges

The NICE recommended target blood glucose levels are stated below for adults with type 1 diabetes, type 2 diabetes and children with type 1 diabetes.

In addition, the International Diabetes Federations target ranges for people without diabetes is stated.

The table provides general guidance. An individual target set by your healthcare team is the one you should aim for.

Blood Sugar Level Charts For Those With Diabetes

Normal blood sugar levels, for those with diabetes, will vary depending on someones age and the time of day. For example, when fasting, blood sugar levels are often in the target goal range. The type of food eaten will impact blood sugar levels in different ways. A meal with a lot of carbohydrates will raise blood sugar quicker than a meal that contains carbohydrates, protein, and fat . Blood sugar will rise after a meal, but will start to return to normal levels in several hours.

Lets take a look at what blood sugar levels should be, in those with diabetes, based on their age.

Fasting Blood Sugar Test

This test can be done in the lab or the healthcare providers office with a simple finger stickor your doctor may prescribe a meter and have you test regularly at home.

A fasting blood sugar level indicates what your blood sugar is when you havent eaten for at least 8 hours. For adults without diabetes, a normal fasting blood sugar is less than 100 mg/dL. A fasting blood sugar level of 100-125 mg/dL indicates prediabetes, and 126 mg/dL or higher indicates diabetes.

How Can One Tell If I Have Diabetes By Examining My Blood

Your body converts sugar, also called glucose, into energy so your body can function. The sugar comes from the foods you eat and is released from storage from your bodys own tissues.

Insulin is a hormone made by the pancreas. Its job is to move glucose from the bloodstream into the cells of tissues. After you eat, the level of glucose in the blood rises sharply. The pancreas responds by releasing enough insulin to handle the increased level of glucose moving the glucose out of the blood and into cells. This helps return the blood glucose level to its former, lower level.

If a person has diabetes, two situations may cause the blood sugar to increase:

• The pancreas does not make enough insulin
• The insulin does not work properly

As a result of either of these situations, the blood sugar level remains high, a condition called hyperglycemia or diabetes mellitus. If left undiagnosed and untreated, the eyes, kidneys, nerves, heart, blood vessels and other organs can be damaged. Measuring your blood glucose levels allows you and your doctor to know if you have, or are at risk for, developing diabetes.

Much less commonly, the opposite can happen too. Too low a level of blood sugar, a condition called hypoglycemia, can be caused by the presence of too much insulin or by other hormone disorders or liver disease.

Can Other Blood Glucose Tests Be Used To Diagnose Type 2 Diabetes And Prediabetes

Yes. Health care professionals also use the fasting plasma glucose test and the OGTT to diagnose type 2 diabetes and prediabetes. For these blood glucose tests used to diagnose diabetes, you must fast at least 8 hours before you have your blood drawn. If you have symptoms of diabetes, your doctor may use the random plasma glucose test, which doesnt require fasting. In some cases, health care professionals use the A1C test to help confirm the results of another blood glucose test.

Make Exercise An Important Part Of Your Daily Routine:

Following a regular exercise program will help keep your blood sugar levels stable. Exercising for an hour at least 3 days a week is recommended to help maintain normal sugar levels. So, including exercise in your daily life will not only reduce your chances of getting diabetes but also help in maintaining a healthy mind and body.

Blood Sugar Levels During Pregnancy

The NIDDK states that gestational diabetes is high blood sugar that occurs during pregnancy if you were not diabetic before getting pregnant. Healthy blood sugar during pregnancy can help lower your risk of developing type 2 diabetes later. It can also lower the risk of your baby being born prematurely, at a high birth weight, and having respiratory problems.

Blood sugar and insulin levels during the first trimester of pregnancy tend to be lower than usual, but they rise during the late second and early third trimesters. You can be diagnosed with an oral glucose tolerance test .

These are the steps for the 2-step strategy.

• Drink a solution with 50 grams of glucose about the amount in 1 16-oz. bottle of a soft drink
• Get your blood drawn after 1 hour. Ig the value is high, retest
• Fast overnight
• Drink a solution with 100 grams of glucose about the amount in 12 peanut butter cups
• Get your blood drawn immediately and after 1, 2, and 3 hours

Or, your doctor might use the 1-step strategy with a 2-hour OGTT:

• Fast overnight
• Drink a solution with 75 grams of glucose
• Get your blood drawn immediately and after 1 and 2 hours

These are some values to know from NIDKK related to gestational diabetes and healthy blood sugar in pregnancy.

How To Measure Blood Sugar Levels

There are two main ways to check your blood sugar levels:

Type 1 diabetics, along with some type 2 diabetics, who require insulin medication, must check their blood sugar at least four times per day, says Mathioudakis. Typically, this should be done before a meal, one to two hours after a meal, and at bedtime.

The timing of these measurements can help determine how much insulin to use. For example, it can be important to use more insulin after a high-sugar meal, or to avoid falling into hypoglycemia while you’re sleeping.

To check your blood sugar at home, you should use blood glucose tests, such as a glucose meter or continuous glucose monitor . Both devices measure blood sugar with the unit mg/dL, which means a milligram of sugar per deciliter of blood.

If you don’t have diabetes, but you may be at risk, your doctor might have you take an A1C test during a yearly check-up. This test reports results as a percentage the higher the percentage, the higher your blood sugar has been in the past three months. Those with diabetes should get an A1C test at least twice a year and sometimes every three months.
