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 >>
A Good Number
R ecently I received an e-mail with the following question, and think it’s worth some commentary: “I have type 2 diabetes and it’s like a yo-yo. I’d like to know exactly what a good number is.” I’ve always had a simple answer to whether blood glucose (BG) numbers are “good” or “bad:” they are neither They are simply numbers: high, in the target range, or low, but there’s no goodness (nor badness) in a number. More important, to answer the question, are several hidden issues: First, does the patient have proper technique to check their BG? Not only knowing how to calibrate and use the meter, but are they checking routinely before meals, or after meals (and if so, how long after eating), or both before and after? And how often? And how big is the yo-yo effect? If the patient is occasionally checking after a big meal and comparing the value to what they get before meals, the “spread” will be a lot bigger than if they are only checking before meals. Is the patient checking before breakfast, and finding that it’s high compared to before other meals? That’s probably due to the “dawn phenomenon,” in which night-time release of other hormones can cause early-morning elevations of blood glucose levels. Is the patient perchance on a diabetes program that includes varying insulin doses? If so, it’s possible that the instructions provided to the patient about insulin adjustment are actually causing a roller-coaster effect, and if so, the insulin instructions need to be changed. Is the patient on a stable meal plan, stable exercise program, and have stable stress levels? If any of these are changing from one moment to the next, it’s no surprise that the BG levels would fluctuate. Now, back to the question: where should the BG levels for someone Continue reading >>
Type 2 Diabetes
Print Diagnosis To diagnose type 2 diabetes, you'll be given a: 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 you have diabetes. A result between 5.7 and 6.4 percent is considered prediabetes, which indicates a high risk of developing diabetes. Normal levels are below 5.7 percent. If the A1C test isn't available, or if you have certain conditions — such as if you're pregnant or have an uncommon form of hemoglobin (known as a hemoglobin variant) — that can make the A1C test inaccurate, your doctor may use the following tests to diagnose diabetes: Random blood sugar test. A blood sample will be taken at a random time. Blood sugar values are expressed in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Regardless of when you last ate, a random blood sugar level of 200 mg/dL (11.1 mmol/L) or higher suggests diabetes, especially when coupled with any of the signs and symptoms of diabetes, such as frequent urination and extreme thirst. Fasting blood sugar test. A blood sample will be taken after an overnight fast. A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes. Oral glucose tolerance test. For this test, you fast overnight, and the fasting blood sugar level is measured. Then you drink a sugary liquid, and blood s Continue reading >>
Analyzing Your Numbers: When Is It Diabetes?
Know the Numbers According to the American Diabetes Association's Standards of Medical Care, these numbers should be used to diagnose pre-diabetes and type 2 diabetes. The ADA suggests everyone over age 45 be checked every three years -- especially if your body mass index (BMI) is over 25. People with a family history of diabetes should be tested at a younger age and more frequently. Normal Fasting glucose level: Less than 100 mg/dl Two hours after eating: Less than 140 mg/dl Pre-Diabetes Fasting glucose level: Equal to or greater than 100 mg/dl and less than 126 mg/dl Two hours after eating: Equal to or greater than 140 mg/dl and less than 200 mg/dl Type 2 Diabetes Fasting glucose level: Equal to or greater than 126 mg/dl. A second test is required for confirmation. Two hours after eating: Equal to or greater than 200 mg/dl. A second test is required for confirmation. Aim for these Targets Maintaining recommended targets for the following risk factors may help you avoid heart disease and type 2 diabetes. Aim for the targets below, as recommended by the ADA in its CheckUp America program at checkupamerica.org. Weight: Body mass index between 19 and 25 Waist circumference: Less than 35 inches for women and 40 inches for men LDL (bad) cholesterol: Less than 100 mg/dl HDL (good) cholesterol: Greater than 60 mg/dl Total cholesterol: Less than 200 mg/dl Triglycerides: Less than 150 mg/dl Blood pressure: Less than 120/80 mmHg Blood glucose: Less than 100 mg/dl Smoking cigarettes: No safe level Physical activity: At least 30 minutes of moderate activity most days Determining Your BMI Body mass index (BMI) is a ratio of weight to height that's used to measure body fat. Use this formula to calculate your BMI or go to nhlbisupport.com/bmi/bmicalc.htm for a quick calculation. Then Continue reading >>
What Your Blood Glucose Numbers Mean
In order to get a complete picture of your blood glucose throughout the day, it is useful to test at different times. Your doctor will help you set your blood glucose targets. Here is what the numbers can mean. These examples are based upon the American Diabetes Association guidelines. Fasting blood glucose before breakfast. This reading on an empty stomach shows how well you use the long-acting insulin that you take. The number should be between 4 and 7 mmol/L. Pre-meal blood glucose before lunch and dinner. This reading shows the effectiveness of your breakfast and lunch insulin doses. The number should be between 4 and 7. Two hours after eating. Your blood glucose peaks a few hours after you eat. This reading shows if the insulin you took was enough to cover the carbs you ate. The reading should be less than 10 mmol/L. Just before bedtime. A target range for someone with diabetes is 6 to 8 mmol/L. You don't want to go to bed with blood glucose that is too low, because that puts you at risk of having a severe low blood sugar episode during the night. Blood Glucose Level Ask Your Doctor If your blood glucose before breakfast is lower than 4 mmol/L, that may be too low. Ask your doctor if you should eat a small snack before you go to bed or reduce your bedtime dose of long-acting insulin. You might want to do a 3:00 am blood glucose check. If the reading before breakfast is over 7 mmol/L, and several 3:00 am readings are in your target range, you may be experiencing "Dawn Phenomenon". This happens when levels of growth hormone begin to rise in the early morning hours, stimulating the liver to release glucose into the bloodstream. Ask your doctor if your supper or bedtime NPH insulin dose needs to be increased, or if you would do better using a different type of insulin. Continue reading >>

Know Your Diabetes Health Numbers
Tweet Monitoring your weight and knowing how much you should weigh is just one of many diabetes health numbers you need to know. In order to maintain good health, every diabetic should know a number of different figures relating to their bodies. These include height, weight, blood pressure and cholesterol levels. Type 2 diabetes is associated with being overweight and obese, and maintaining a healthy weight allows easier control of diabetes. The following health numbers also affect your cardiovascular health. Print out, fill in and cut out the following table: Essential numbers for diabetic health HbA1c (%) Ave. Blood Glucose (mmol/L) Age ___ years Height ___ metres/ft Weight ___ kg/stone Waist ___ inches/cm Blood pressure ___ mm/Hg Blood glucose ___ mmol/L Blood cholesterol ___ mmol/L Are there other essential numbers I need to remember for diabetic health? Yes, but the numbers above can help in a variety of diagnostics. They could indicate to you a danger of heart attack or stroke. Read about Diabetes Health Guidelines Once your medical history, gender and health history are understood, a clearer diagnosis can be reached. I can’t fill in the form above. Why do I need to do it? Most people will be able to determine their age, height and weight, but this does not make these numbers any less important. These figures are essential to calculate your body mass index. Why do I need to know my waist circumference? Your waist shows how much abdominal fat you have, and increased girth can signify an increased risk of cardiovascular disease or diabetes. Weight gain can also be a sign of ‘insulin resistance.’ You should measure around your relaxed stomach at belly button level. Men who have a waist circumference of 94-102cm face a 1.5-2 times greater risk of suffering from Continue reading >>
Know Your Blood Sugar Numbers: Use Them To Manage Your Diabetes
Checking your blood sugar, also called blood glucose, is an important part of diabetes care. This tip sheet tells you: why it helps you to know your blood sugar numbers how to check your blood sugar levels what are target blood sugar levels what to do if your levels are too low or too high how to pay for these tests Why do I need to know my blood sugar numbers? Your blood sugar numbers show how well your diabetes is managed. And managing your diabetes means that you have less chance of having serious health problems, such as kidney disease and vision loss. As you check your blood sugar, you can see what makes your numbers go up and down. For example, you may see that when you are stressed or eat certain foods, your numbers go up. And, you may see that when you take your medicine and are active, your numbers go down. This information lets you know what is working for you and what needs to change. How is blood sugar measured? There are two ways to measure blood sugar. Blood sugar checks that you do yourself. These tell you what your blood sugar level is at the time you test. The A1C (A-one-C) is a test done in a lab or at your provider’s office. This test tells you your average blood sugar level over the past 2 to 3 months. How do I check my blood sugar? You use a blood glucose meter to check your blood sugar. This device uses a small drop of blood from your finger to measure your blood sugar level. You can get the meter and supplies in a drug store or by mail. Read the directions that come with your meter to learn how to check your blood sugar. Your health care team also can show you how to use your meter. Write the date, time, and result of the test in your blood sugar record. Take your blood sugar record and meter to each visit and talk about your results with your h Continue reading >>
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 >>
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 >>
All About The Hemoglobin A1c Test
People with diabetes used to depend only on urine tests or daily finger sticks to measure their blood sugars. These tests are accurate, but only in the moment. As an overall measurement of blood sugar control, they’re very limited. This is because blood sugar can vary wildly depending on the time of day, activity levels, and even hormone changes. Some people may have high blood sugars at 3 a.m. and be totally unaware of it. Once A1C tests became available in the 1980s, they became an important tool in controlling diabetes. A1C tests measure average blood glucose over the past two to three months. So even if you have a high fasting blood sugar, your overall blood sugars may be normal, or vice versa. A normal fasting blood sugar may not eliminate the possibility of type 2 diabetes. This is why A1C tests are now being used for diagnosis and screening of prediabetes. Because it doesn’t require fasting, the test can be given as part of an overall blood screening. The A1C test is also known as the hemoglobin A1C test or HbA1C test. Other alternate names include the glycosylated hemoglobin test, glycohemoglobin test, and glycated hemoglobin test. A1C measures the amount of hemoglobin in the blood that has glucose attached to it. Hemoglobin is a protein found inside red blood cells that carries oxygen to the body. Hemoglobin cells are constantly dying and regenerating, but they have a lifespan of approximately three months. Glucose attaches, or glycates, to hemoglobin, so the record of how much glucose is attached to your hemoglobin also lasts for about three months. If there’s too much glucose attached to the hemoglobin cells, you’ll have a high A1C. If the amount of glucose is normal, your A1C will be normal. The test is effective because of the lifespan of the hemogl 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 >>
Diabetes By The Numbers
When you have type 2 diabetes, you’ve got to know your numbers. It’s not just about blood sugar. To successfully manage diabetes, there are several measurements that you should take, or have taken, on a regular basis. Keeping track of the following numbers can help you live well with type 2 diabetes and lower your risk of complications. Blood sugar levels. This is probably the type 2 diabetes measure you’re most familiar with. Testing your blood sugar regularly allows you to see how certain foods, exercise, and other activities affect your blood sugar levels on a day-to-day basis. Many people with type 2 diabetes need to test once or twice a day to make sure blood sugar levels are in target range. If your blood sugar is very well controlled, you may only need to check a few times a week, according to the National Institutes of Health. The American Diabetes Association recommends aiming for a blood sugar level between 70 to 130 mg/dl before meals and less than 180 mg/dl one to two hours after a meal. To keep your blood sugar within this range, follow a healthy, well-rounded diet and eat meals and snacks on a consistent schedule. If your blood sugar is not well controlled, talk to your doctor about adjusting your diabetes management plan. A1C level. This is a blood test, typically given at doctor's appointments, that measures your average blood sugar levels over a longer period. “It gives you a picture of what’s been going on over the past two to three months,” says Dawn Sherr, RD, a certified diabetes educator and spokesperson for the American Association of Diabetes Educators. Essentially, your A1C result shows how well your diabetes treatment plan is working. Depending on your results, you may need to have the test from two to four times a year. For most pe Continue reading >>
8 Numbers You Need To Know For Diabetes
How to Manage Diabetes With Numbers Diabetes self-management is a numbers game. But it's not just about your blood sugar. There are at least eight different numbers you should be familiar with to lower your risk for complications from diabetes symptoms. "Diabetes self-management is absolutely essential," says Enrico Cagliero, MD, an associate professor of medicine at Harvard Medical School and an associate physician at the Massachusetts General Hospital Diabetes Center. "Although managing these numbers may not improve diabetes symptoms, it can help decrease the risk of serious complications such as blindness or kidney failure down the road." Continue reading >>
What Is A Good Score On The A1c Diabetes Test?
Normal A1C level can range from 4.5 to 6 percent. Someone who's had uncontrolled diabetes for a long time can have an A1C level above 9 percent. A1C test is used to diagnose diabetes, an A1C level of 6.5 percent or higher on two separate dates indicates diabetes. A result between 5.7 and 6.4 percent is considered prediabetes, which is high risk of developing diabetes. For most people who have previously diagnosed diabetes, an A1C level of 7 percent or less is a common treatment target. Higher targets may be chosen in some individuals. If your A1C level is above your target, your doctor may recommend a change in your diabetes treatment plan. Remember, the higher your A1C level, the higher your risk of diabetes complications. A good score on the A1C test depends on whether you’ve been diagnosed with diabetes. For those who do not have diabetes, a score of less than 5.7% is considered normal, while 5.7% to 6.4% indicates prediabetes and 6.5% or higher means you have diabetes. If you already have diabetes, a score of 7% or lower is desired. You and your doctor can decide what score is best for you. The A1C diabetes test is a way to get an average of how well your blood sugar has been controlled for the past three months. The standard A1C goal for most people with diabetes is less than 7%. However, the goal may be individualized or may be different for some people, especially older adults, people with heart disease or those who are prone to frequent low blood glucose. It's a good idea to find out what your A1C goal should be from your healthcare provider and then use that as a benchmark for your A1C results. No one quite agrees on where your A1C score should be, but we all agree on where it shouldn’t be. The scale does not look anything like the BGL numbers you are used 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.
