What Is A Normal Blood Sugar Level?
The aim of diabetes treatment is to bring blood sugar (“glucose”) as close to normal as possible. What is a normal blood sugar level? And how can you achieve normal blood sugar? First, what is the difference between “sugar” and “glucose”? Sugar is the general name for sweet carbohydrates that dissolve in water. “Carbohydrate” means a food made only of carbon, oxygen, and hydrogen. There are various different kinds of sugars. The one our body uses most is called “glucose.” Other sugars we eat, like fructose from fruit or lactose from milk, are converted into glucose in our bodies. Then we can use them for energy. Our bodies also break down starches, which are sugars stuck together, into glucose. When people talk about “blood sugar,” they mean “blood glucose.” The two terms mean the same thing. In the U.S., blood sugar is normally measured in milligrams of glucose per deciliter of blood (mg/dl). A milligram is very little, about 0.00018 of a teaspoon. A deciliter is about 3 1/3 ounces. In Canada and the United Kingdom, blood sugar is reported in millimoles/liter (mmol/L). You can convert Canadian or British glucose levels to American numbers if you multiply them by 18. This is useful to know if you’re reading comments or studies from England or Canada. If someone reports that their fasting blood glucose was 7, you can multiply that by 18 and get their U.S. glucose level of 126 mg/dl. What are normal glucose numbers? They vary throughout the day. (Click here for a blood sugar chart.) For someone without diabetes, a fasting blood sugar on awakening should be under 100 mg/dl. Before-meal normal sugars are 70–99 mg/dl. “Postprandial” sugars taken two hours after meals should be less than 140 mg/dl. Those are the normal numbers for someone w Continue reading >>
Controlling Blood Sugar In Diabetes: How Low Should You Go?
Diabetes is an ancient disease, but the first effective drug therapy was not available until 1922, when insulin revolutionized the management of the disorder. Insulin is administered by injection, but treatment took another great leap forward in 1956, when the first oral diabetic drug was introduced. Since then, dozens of new medications have been developed, but scientists are still learning how best to use them. And new studies are prompting doctors to re-examine a fundamental therapeutic question: what level of blood sugar is best? Normal metabolism To understand diabetes, you should first understand how your body handles glucose, the sugar that fuels your metabolism. After you eat, your digestive tract breaks down carbohydrates into simple sugars that are small enough to be absorbed into your bloodstream. Glucose is far and away the most important of these sugars, and it's an indispensable source of energy for your body's cells. But to provide that energy, it must travel from your blood into your cells. Insulin is the hormone that unlocks the door to your cells. When your blood glucose levels rise after a meal, the beta cells of your pancreas spring into action, pouring insulin into your blood. If you produce enough insulin and your cells respond normally, your blood sugar level drops as glucose enters the cells, where it is burned for energy or stored for future use in your liver as glycogen. Insulin also helps your body turn amino acids into proteins and fatty acids into body fat. The net effect is to allow your body to turn food into energy and to store excess energy to keep your engine running if fuel becomes scarce in the future. A diabetes primer Diabetes is a single name for a group of disorders. All forms of the disease develop when the pancreas is unable to Continue reading >>
Print Symptoms of type 1 diabetes often appear suddenly and are often the reason for checking blood sugar levels. Because symptoms of other types of diabetes and prediabetes come on more gradually or may not be evident, the American Diabetes Association (ADA) has recommended screening guidelines. The ADA recommends that the following people be screened for diabetes: Anyone with a body mass index higher than 25, regardless of age, who has additional risk factors, such as high blood pressure, a sedentary lifestyle, a history of polycystic ovary syndrome, having delivered a baby who weighed more than 9 pounds, a history of diabetes in pregnancy, high cholesterol levels, a history of heart disease, and having a close relative with diabetes. Anyone older than age 45 is advised to receive an initial blood sugar screening, and then, if the results are normal, to be screened every three years thereafter. Tests for type 1 and type 2 diabetes and prediabetes Glycated hemoglobin (A1C) test. This blood test indicates your average blood sugar level for the past two to three months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells. The higher your blood sugar levels, the more hemoglobin you'll have with sugar attached. An A1C level of 6.5 percent or higher on two separate tests indicates that you have diabetes. An A1C between 5.7 and 6.4 percent indicates prediabetes. Below 5.7 is considered normal. If the A1C test results aren't consistent, the test isn't available, or if you have certain conditions that can make the A1C test inaccurate — such as if you're pregnant or have an uncommon form of hemoglobin (known as a hemoglobin variant) — your doctor may use the following tests to diagnose diabetes: Random blood sugar Continue reading >>
Is My Blood Sugar Normal?
“Is my blood sugar normal?” seems like a simple question – but it’s not! The answer can vary dramatically based on your situation. Let’s look at some of the factors to consider. Please remember: you should figure out your personal goals in consultation with your doctor. Normal Blood Sugar in Diabetic vs. Non-Diabetic First, a quick note on how we measure blood sugar. In the USA, blood sugars are measured by weight in milligrams per deciliter, abbreviated as mg/dL. Most everyone else uses millimole per liter, abbreviated mmol. If you are in the USA, look at the big numbers, most everyone else look at the small numbers. In a person without diabetes, blood sugars tend to stay between 70 and 100 mg/dL (3.8 and 5.5 mmol). After a meal, blood sugars can rise up to 120 mg/dL or 6.7 mmol. It will typically fall back into the normal range within two hours. In a person with diabetes, the story is much more complex: Below 70 mg/dL Below 3.8 mmol Low Blood Sugars (Hypoglycemia). When blood sugars drop below this level, you may start feeling hunger, shakiness, or racing of the heart. Your body is starved for sugar (glucose). Read how to detect and treat low blood sugars. 70 mg/dL to 140 mg/dL 3.8 mmol to 7.7 mmol Normal Blood Sugar. In this range, the body is functioning normally. In someone without diabetes, the vast majority of the time is spent in the lower half of this range. 140 mg/dL to 180 mg/dL 7.7 mmol to 10 mmol Elevated Blood Sugars. In this range, the body can function relatively normally. However, extended periods of time in this zone put you at risk for long-term complications. Above 180 mg/dL Abovoe 10 mmol High Blood Sugars. At this range, the kidney is unable to reabsorb all of the glucose in your blood and you begin to spill glucose in your urine. Your bo Continue reading >>

What Are Blood Sugar Target Ranges? What Is Normal Blood Sugar Level?
Understanding blood sugar target ranges to better manage your diabetes As a person with diabetes, you may or may not know what your target ranges should be for your blood sugars first thing in the morning, before meals, after meals, or at bedtime. You may or may not understand what blood sugar ranges are for people without diabetes. You may or may not understand how your A1C correlates with your target ranges. How do you get a clear picture of what is going on with your blood sugar, and how it could be affecting your health? In this article, we will look at what recommended blood sugar target ranges are for people without diabetes. We will look at target ranges for different times of the day for people with diabetes. We will look at target ranges for Type 1 versus Type 2 diabetes. Is there a difference? We will also look at what blood sugars should be during pregnancy for those with gestational diabetes. We will look at other factors when determining blood sugar targets, such as: Age Other health conditions How long you’ve had diabetes for Stress Illness Lifestyle habits and activity levels We will see how these factors impact target ranges for your blood sugars when you have diabetes. We will learn that target ranges can be individualized based on the factors above. We will learn how target ranges help to predict the A1C levels. We will see how if you are in your target range, you can be pretty sure that your A1C will also be in target. We will see how you can document your blood sugar patterns in a notebook or in an “app,” and manage your blood sugars to get them in your target ranges. First, let’s look at the units by which blood sugars are measured… How is blood sugar measured? In the United States, blood sugar is measured in milligrams per deciliter (by w Continue reading >>
Blood Sugar Level
The fluctuation of blood sugar (red) and the sugar-lowering hormone insulin (blue) in humans during the course of a day with three meals. One of the effects of a sugar-rich vs a starch-rich meal is highlighted. The blood sugar level, blood sugar concentration, or blood glucose level is the amount of glucose present in the blood of humans and other animals. Glucose is a simple sugar and approximately 4 grams of glucose are present in the blood of humans at all times. The body tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is stored in skeletal muscle and liver cells in the form of glycogen; in fasted individuals, blood glucose is maintained at a constant level at the expense of glycogen stores in the liver and skeletal muscle. In humans, glucose is the primary source of energy, and is critical for normal function, in a number of tissues, particularly the human brain which consumes approximately 60% of blood glucose in fasted, sedentary individuals. Glucose can be transported from the intestines or liver to other tissues in the body via the bloodstream. Cellular glucose uptake is primarily regulated by insulin, a hormone produced in the pancreas. Glucose levels are usually lowest in the morning, before the first meal of the day, and rise after meals for an hour or two by a few millimoles. Blood sugar levels outside the normal range may be an indicator of a medical condition. A persistently high level is referred to as hyperglycemia; low levels are referred to as hypoglycemia. Diabetes mellitus is characterized by persistent hyperglycemia from any of several causes, and is the most prominent disease related to failure of blood sugar regulation. There are different methods of testing and measuring blood sugar le Continue reading >>
Managing Diabetes With Blood Glucose Control
There are two common ways that physicians assess how well diabetes is controlled:  Frequent measurements of blood glucose, and  measurement of glycohemoglobin (A1c). Each method has its good and bad points, but combined they give a fairly accurate picture of the state of glucose control in a diabetic. Most physicians will use both methods. Why Tight Blood Glucose Is Important Measurement of Blood Glucose (Blood Sugar) When we speak about measuring blood glucose levels, it can be done 2 different ways. Blood glucose can be measured randomly from a sample taken at any time (called a "random blood sugar" or RBS). Blood glucose can also be measured in the "fasting" state, meaning that the person has not eaten or taken in any calories in the past 8 hours (usually this is done overnight and it is referred to as an overnight fast and is called a "fasting blood sugar" or FBS). In a person with normal insulin production and activity (a non-diabetic) blood sugar levels will return to "fasting" levels within 3 hours of eating. People with diabetes (type 1 and type 2) may not be able to get their blood glucose down this quickly after a meal or drinking a calorie-containing drink. More about this can be found on our Diagnosing Diabetes page. Learn More about How to Manage Diabetes Remember, the normal fasting blood glucose level is between 70 and 110 mg/dL. Frequent Measurements of Blood Glucose. The goal in this part of diabetes management is to strive to keep fasting blood sugars under 140 mg/dL and preferably closer to the 70 to 120 mg/dL range. Ideally, one could monitor blood sugars 4 times per day (or more) to follow how well the sugars are controlled. This information could be used to adjust your diet and medications to achieve this goal. Usually blood glucose measureme Continue reading >>

Is There A 'safe' Blood Sugar Level?
What is the "safe" blood sugar level? I have heard several opinions from other diabetics, and I am very confused. I was told that it was 154 about a year ago, and my doctor didn't recommend daily monitoring. At one time on a morning fasting, my level was 74. — Theresa, Alabama Yes, there is a safe blood sugar level. It is the optimum range that safely provides the body with adequate amounts of energy. For the average person, it is 70 to 105 mg/dl in a fasting state. (Diabetes is diagnosed when the fasting blood glucose level is at or above 126 mg/dl.) Glucose values vary depending on the time of day, your activity level, and your diet. Your sugar level of 154 mg/dl, which is high, may not have been determined while you were fasting. If it had been, a physician would have repeated the test. Your doctor did, and your level was determined to be normal at 74 mg/dl. In this case, daily monitoring is probably not necessary. If your levels are elevated in the future, you will be diagnosed with diabetes. Treatment can include lifestyle modification, diet, and exercise. If these strategies are not adequate to control your blood glucose level, your physician may prescribe oral medicines or insulin. Having a laboratory examination during your yearly physical and maintaining a healthy lifestyle are adequate for now. Why is it important to keep your glucose level within a normal range? An excess of glucose in the bloodstream causes various chemical changes that lead to damage to our blood vessels, nerves, and cells. Each cell in the body has a function that requires energy, and this energy comes primarily from glucose. The energy allows you to perform various tasks, including talking and walking. It allows your heart to beat and your brain to produce chemicals and signals that hel Continue reading >>
Blood Sugar Levels For Adults With Diabetes
Each time you test your blood sugar, log it in a notebook or online tool or with an app. Note the date, time, results, and any recent activities: What medication and dosage you took What you ate How much and what kind of exercise you were doing That will help you and your doctor see how your treatment is working. Well-managed diabetes can delay or prevent complications that affect your eyes, kidneys, and nerves. Diabetes doubles your risk for heart disease and stroke, too. Fortunately, controlling your blood sugar will also make these problems less likely. Tight blood sugar control, however, means a greater chance of low blood sugar levels, so your doctor may suggest higher targets. Continue reading >>
Blood Sugar Level Ranges
Tweet Understanding blood glucose level ranges can be a key part of diabetes self-management. This page states 'normal' blood sugar ranges and blood sugar ranges for adults and children with type 1 diabetes, type 2 diabetes and blood sugar ranges to determine people with diabetes. If a person with diabetes has a meter, test strips and is testing, it's important to know what the blood glucose level means. Recommended blood glucose levels have a degree of interpretation for every individual and you should discuss this with your healthcare team. In addition, women may be set target blood sugar levels during pregnancy. The following ranges are guidelines provided by the National Institute for Clinical Excellence (NICE) but each individual’s target range should be agreed by their doctor or diabetic consultant. 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 Federation's 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. NICE recommended target blood glucose level ranges Target Levels by Type Upon waking Before meals (pre prandial) At least 90 minutes after meals (post prandial) Non-diabetic* 4.0 to 5.9 mmol/L under 7.8 mmol/L Type 2 diabetes 4 to 7 mmol/L under 8.5 mmol/L Type 1 diabetes 5 to 7 mmol/L 4 to 7 mmol/L 5 to 9 mmol/L Children w/ type 1 diabetes 4 to 7 mmol/L 4 to 7 mmol/L 5 to 9 mmol/L *The non-diabetic figures are provided for information but are not part of NICE guidelines.

Normal Blood Sugar Levels: What People With Diabetes And Prediabetes Need To Know
The word diabetes is often associated with the word blood sugar. But what exactly is blood sugar and what constitutes as a normal blood sugar level? Blood glucose, also known as blood sugar, is the major source of energy used throughout your body to power all of its functions. Blood sugar varies throughout the day and rises after you eat a meal. When you eat, your body breaks down the food into smaller components that then move throughout the bloodstream. Different foods break down into different nutrients: proteins break down into amino acids, fats break down into fatty acids, and carbohydrates break down into glucose, which essentially powers up your cells to give your entire body the energy it needs. When you have diabetes, your cells aren’t as able to process glucose, so it builds up in your blood, ultimately causing high blood sugar. For someone without diabetes: A fasting blood sugar level (when you first wake up in the morning) should be under 100 mg/dL (measured in units of milligrams of glucose per deciliter of blood). Before meal normal sugar levels should be between 70-99 mg/dL. For someone with diabetes: Blood sugar levels tend to be higher than what is considered to be normal and healthy. The less you control your diabetes, the more likely your blood sugar is to remain high or swing drastically between highs and lows. According to the American Diabetes Association (ADA), fasting blood sugar levels before meals should be kept between 80-130 mg/dL. If you have diabetes, or have reason to believe you are diabetic, there are several tests that can be done to diagnose or check your blood sugar levels. Read more about the most common tests for diabetes here. When it comes to diabetes, it’s important to give your body conscious help and attention. Eating right Continue reading >>
Goals For Blood Glucose Control
People who have diabetes should be testing their blood glucose regularly at home. Regular blood glucose testing helps you determine how well your diabetes management program of meal planning, exercising and medication (if necessary) is doing to keep your blood glucose as close to normal as possible. The results of the nationwide Diabetes Control and Complications Trial (DCCT) show that the closer you keep your blood glucose to normal, the more likely you are to prevent diabetes complications such as eye disease, nerve damage, and other problems. For some people, other medical conditions, age, or other issues may cause your physician to establish somewhat higher blood glucose targets for you. The following chart outlines the usual blood glucose ranges for a person who does and does not have diabetes. Use this as a guide to work with your physician and your healthcare team to determine what your target goals should be, and to develop a program of regular blood glucose monitoring to manage your condition. Time of Check Goal plasma blood glucose ranges for people without diabetes Goal plasma blood glucose ranges for people with diabetes Before breakfast (fasting) < 100 70 - 130 Before lunch, supper and snack < 110 70 - 130 Two hours after meals < 140 < 180 Bedtime < 120 90- 150 A1C (also called glycosylated hemoglobin A1c, HbA1c or glycohemoglobin A1c) < 6% < 7% < = less than > = greater than > = greater than or equal to < = less than or equal to Information obtained from Joslin Diabetes Center's Guidelines for Pharmacological Management of Type 2 Diabetes.

Must Read Articles Related To High Blood Sugar (hyperglycemia)
A A A High Blood Sugar (Hyperglycemia) Whenever the glucose (sugar) level in one's blood rises high temporarily, this condition is known as hyperglycemia. The opposite condition, low blood sugar, is called hypoglycemia. Glucose comes from most foods, and the body uses other chemicals to create glucose in the liver and muscles. The blood carries glucose (blood sugar) to all the cells in the body. To carry glucose into the cells as an energy supply, cells need help from insulin. Insulin is a hormone made by the pancreas, an organ near the stomach. The pancreas releases insulin into the blood, based upon the blood sugar level. Insulin helps move glucose from digested food into cells. Sometimes, the body stops making insulin (as in type 1 diabetes), or the insulin does not work properly (as in type 2 diabetes). In diabetic patients, glucose does not enter the cells sufficiently, thus staying in the blood and creating high blood sugar levels. Blood sugar levels can be measured in seconds by using a blood glucose meter, also known as a glucometer. A tiny drop of blood from the finger or forearm is placed on a test strip and inserted into the glucometer. The blood sugar (or glucose) level is displayed digitally within seconds. Blood glucose levels vary widely throughout the day and night in people with diabetes. Ideally, blood glucose levels range from 90 to 130 mg/dL before meals, and below 180 mg/dL within 1 to 2 hours after a meal. Adolescents and adults with diabetes strive to keep their blood sugar levels within a controlled range, usually 80-150 mg/dL before meals. Doctors and diabetes health educators guide each patient to determine their optimal range of blood glucose control. When blood sugar levels remain high for several hours, dehydration and more serious complicat Continue reading >>
Blood Glucose Monitoring
One of the main aims of diabetes treatment is to keep blood glucose levels within a specified target range. The key is balancing your food with your activity, lifestyle and diabetes medicines. Blood glucose monitoring can help you understand the link between blood glucose, food, exercise and insulin. Over time your readings will provide you and your health professionals with the information required to determine the best management strategy for your diabetes. Maintaining good blood glucose control is your best defence to reduce the chances of developing complications from diabetes. Self-blood glucose monitoring allows you to check your blood glucose levels as often as you need to or as recommended by your doctor or Credentialled Diabetes Educator. To test blood glucose levels, you need: A blood glucose meter A lancet device with lancets Test strips. Blood glucose meters are usually sold as kits giving you all the equipment you need to start. There are many different types, offering different features and at different prices to meet individual needs. Most of these are available from Diabetes Australia in your state or territory, pharmacies and some diabetes centres. Your doctor or Credentialled Diabetes Educator can help you choose the meter that’s best for you, and your Credentialled Diabetes Educator or pharmacist can show you how to use your meter to get accurate results. To test your blood glucose levels, you prick your finger with the lancet and add a small drop of blood onto a testing strip. This strip is then inserted into the meter, which reads the strip and displays a number – your blood glucose level. When and how often you should test your blood glucose levels varies depending on each individual, the type of diabetes and the tablets and/or insulin being us Continue reading >>
