What Is A Healthy Blood Sugar Level?
If you don't have diabetes, a healthy blood sugar is less than 126, says Holly Anderson, Outpatient Diabetes Coordinator at Reston Hospital Center. Watch this video to find out the healthy level for someone with diabetes. A healthy blood sugar level, obtained in a fasting state, is less than 100. A fasting blood sugar of greater than 126 is diabetic. A fasting blood sugar between 100 and 126 is considered "prediabetic". Prediabetes can be associated with increased risk for heart disease and should lead to lifestyle changes.

According to the American Diabetes Association, normal blood glucose ranges between 70 to 99 milligrams per deciliter (mg/dL). In a person without diabetes, the body keeps its blood-glucose level between meals in a range of about 70 to 99 milligrams per deciliter (mg/dL). This level will rise after eating, depending on the type and amount of food consumed, but it will not exceed 139 mg/dL. It also quickly returns to the between-meal range. After you have fasted overnight or for an eight-hour period, your doctor can measure your blood glucose levels with a basic blood test. Blood sugar levels of under 100 are considered normal after an eight-hour fast. However, fasting blood glucose levels between 100-125 mg/dl could signal prediabetes. Continue reading >>
Hyperglycemia: When Your Blood Glucose Level Goes Too High
Hyperglycemia means high (hyper) glucose (gly) in the blood (emia). Your body needs glucose to properly function. Your cells rely on glucose for energy. Hyperglycemia is a defining characteristic of diabetes—when the blood glucose level is too high because the body isn't properly using or doesn't make the hormone insulin. You get glucose from the foods you eat. Carbohydrates, such as fruit, milk, potatoes, bread, and rice, are the biggest source of glucose in a typical diet. Your body breaks down carbohydrates into glucose, and then transports the glucose to the cells via the bloodstream. Body Needs Insulin However, in order to use the glucose, your body needs insulin. This is a hormone produced by the pancreas. Insulin helps transport glucose into the cells, particularly the muscle cells. People with type 1 diabetes no longer make insulin to help their bodies use glucose, so they have to take insulin, which is injected under the skin. People with type 2 diabetes may have enough insulin, but their body doesn't use it well; they're insulin resistant. Some people with type 2 diabetes may not produce enough insulin. People with diabetes may become hyperglycemic if they don't keep their blood glucose level under control (by using insulin, medications, and appropriate meal planning). For example, if someone with type 1 diabetes doesn't take enough insulin before eating, the glucose their body makes from that food can build up in their blood and lead to hyperglycemia. Your endocrinologist will tell you what your target blood glucose levels are. Your levels may be different from what is usually considered as normal because of age, pregnancy, and/or other factors. Fasting hyperglycemia is defined as when you don't eat for at least eight hours. Recommended range without diabet Continue reading >>
Slideshow: A Visual Guide To Type 2 Diabetes
If you experience symptoms of severe increased thirst, frequent urination, unexplained weight loss, increased hunger, tingling of your hands or feet -- your doctor may run a test for diabetes. According to the Centers for Disease Control and Prevention, some 29 million children and adults in the U.S., or over 9% of the population, have diabetes today. Yet, millions of Americans are unaware that they have diabetes, because there may be no warning signs. To confirm the diagnosis of type 2 diabetes, your doctor will order a fasting plasma glucose test or a casual plasma glucose. The fasting plasma glucose test (FPG) is the preferred method for diagnosing diabetes, because it is easy to do, convenient, and less expensive than other tests, according to the American Diabetes Association. Before taking the blood glucose test, you will not be allowed to eat anything for at least eight hours. During a blood glucose test, blood will be drawn and sent to a lab for analysis. Normal fasting blood glucose -- or blood sugar -- is between 70 and 100 milligrams per deciliter or mg/dL for people who do not have diabetes. The standard diagnosis of diabetes is made when two separate blood tests show that your fasting blood glucose level is greater than or equal to 126 mg/dL. However, if you have normal fasting blood sugar, but you have risk factors for diabetes or symptoms of diabetes, your doctor may decide to do a glucose tolerance test (see below) to be sure that you do not have diabetes. Some people have a normal fasting blood sugar reading, but their blood sugar rapidly rises as they eat. These people may have impaired glucose tolerance. If their blood sugar levels are high enough, they may be diagnosed with diabetes. Continue reading >>
Blood Sugar: Fasting Vs. Postprandial
Peter's fasting blood glucose: 89 mg/dl--perfect. After one whole wheat bagel, apple, black coffee: 157 mg/dl--diabetic-range. How common is this: Normal fasting blood sugar with diabetic range postprandial (after-eating) blood sugar? It is shockingly common. The endocrinologists have known this for some years, since a number of studies using oral glucose tolerance testing (OGTT) have demonstrated that fasting glucose is not a good method of screening people for diabetes or pre-diabetes, nor does it predict the magnitude of postprandial glucose. (In an OGTT, you usually drink 75 grams of glucose as a cola drink, followed by blood sugar checks. The conventional cut off for "impaired glucose tolerance" is 140-200 mg/dl; diabetes is 200 mg/dl or greater.) People with glucose levels during OGTT as high as 200 mg/dl may have normal fasting values below 100 mg/dl. High postprandial glucose values are a coronary risk factor. While conventional guidelines say that a postprandial glucose (i.e., during OGTT) of 140 mg/dl or greater is a concern, coronary risk starts well below this. Risk is increased approximately 50% at 126 mg/dl. Risk may begin with postprandial glucoses as low as 100 mg/dl. For this reason, postprandial (not OGTT) glucose checks are becoming an integral part of the Track Your Plaque program. We encourage postprandial blood glucose checks, followed by efforts to reduce postprandial glucose if they are high. More on this in future. 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 >>
Random Glucose Tests: Testing Stability
Glucose testing is a random blood test to check glucose levels. It is usually done by pricking the finger to draw a small drop of blood. This blood is then wiped onto a test strip that will give a glucose reading. This is a powerful tool for people with diabetes. It can help assess how well the disease is being managed. Diabetes Diabetes is a disease that affects your body’s ability to release insulin from your pancreas once sugars are turned into glucose. The insulin allows the glucose to enter the bloodstream and release energy. In diabetes, this function does not work properly. Some early symptoms of diabetes are excessive urination and thirst. This is caused by the sugar buildup in the blood that is not absorbed. It is filtered out through the kidneys in large amounts, which can then lead to dehydration. Other symptoms may include weight loss, blurred vision, being tired constantly, tingling in arms and legs, sore gums, and slow healing. Glucose testing helps keep track of symptoms and manage diabetes. Random blood glucose values vary depending on the last time you ate. If you are testing within one to two hours after the start of a meal, the American Diabetes Association (ADA) recommends glucose levels be under 180 mg/dL. Before a meal the levels can be between 80 and 130 mg/dL. A normal glucose reading for someone without diabetes is lower than 140 mg/dL. If the reading is anywhere from 140 mg/dL to 199 mg/dL, there is a chance you suffer from impaired glucose tolerance. This is otherwise known as prediabetes, and there is a chance it can develop into type 2. If the reading is higher than 200 mg/dL, there is a high chance you have diabetes. A doctor may schedule another glucose test for you if it is positive for diabetes. There are a number of factors that can c Continue reading >>
Diabetes: Blood Sugar Readings
www.CardioSmart.org What is a blood sugar reading? A blood sugar reading shows how much sugar, or glucose, is in your blood. A test of your blood sugar may be done to: â€¢ Check for diabetes. â€¢ See how well diabetes treatment is working. â€¢ Check for diabetes that occurs during pregnancy (gestational diabetes). â€¢ Check for low or high blood sugar levels (hypoglycemia or hyperglycemia). What are normal blood sugar readings? There are several types of blood sugar tests. Normal results can vary from lab to lab. Talk with your doctor about what any abnormal results might mean, and about any symptoms and other health problems you have. Normal values for adults who do NOT have prediabetes or diabetes Less than or equal to 100 When you have not eaten (fasting blood sugar): Less than 140 if you are age 50 or younger; less than 150 if you are age 50 to 60; less than 160 if you are age 60 and older 2 hours after eating (postprandial): Levels vary depending on when and how much you ate at your last meal. In general: 80 to 120 beforemeals or when waking up; 100 to 140 at bedtime. Random (casual): Target values for nonpregnant adults who have prediabetes or diabetes 80 to 130When you have not eaten (fasting blood sugar): Less than 1802 hours after eating (postprandial): What causes abnormal blood sugar? High blood sugar can be caused by: â€¢ Diabetes or prediabetes. â€¢ Certain medicines, such as corticosteroids. Low blood sugar can be caused by: â€¢ Certain medicines, especially those used to treat diabetes. â€¢ Liver disease, such as cirrhosis. Rarely, high or low blood sugar can be caused by other medical problems that affect hormone levels. Prediabetes and diabetes Blood sugar helps fuel your body. Normally, your blood sugar rises slightly af Continue reading >>
Blood Glucose Readings: What They Mean
Source: Web exclusive: June 2011 When you have diabetes, perhaps the most important thing you need to know is the level of your blood glucose, also known as your blood sugar. Since many factors can raise or lower your blood glucose, you may have to check it several times a day. But once you obtain a blood glucose reading, what exactly does it mean? Crunch those numbers When you test a drop of your blood with a glucose meter, the big number that pops onto the screen refers to the number of millimoles (mmol) of glucose per litre (L) of your blood. A millimole (mmol) is one-thousandth of a mole, which is a standard unit for measuring the mass of molecules. And if that’s not already confusing enough, the United States uses a completely different system than Canadians for measuring blood glucose. South of the border, blood glucose is measured in milligrams per decilitre (mg/dL). This can sometimes be rather bewildering, especially if you’re brand new to diabetes and researching your disease on the Internet. “I tell people to go to a Canadian site first,” says Tabitha Palmer, a certified diabetes educator at the Centre for Clinical Research in Halifax. Know your targets So what numbers should you be looking for? Your target reading before meals should be between 4 and 7. Your blood sugar normally spikes two hours after a meal, so between 5 and 10 is a good range after you eat. Besides food, other factors that can cause your blood sugar to go up or down include exercise, illness, medications and stress. Your blood glucose readings are hands-down the best way to monitor whether or not your diabetes is generally well managed. "They really help the physicians and educators if we’re trying to look at whether you need to have your medication, insulin or mealtime adjusted, Continue reading >>
Healthy Blood Sugar Targets
If you have been told your blood sugar is higher than normal, you may wonder what blood sugar levels you should be aiming for to ensure ongoing health. Doctors and organizations like the American Diabetes Association suggest various blood sugar targets, but before you adopt any such target, it is worth remembering that the point of setting and adhering to any blood sugar target is to avoid diabetic complications. "Complications" is a euphemism for some very ugly outcomes that include blindness, amputation, kidney failure and death. So the obvious question to ask about any blood sugar target is "What evidence suggests that this blood sugar level is low enough to prevent complications." Research conducted with human patients, mice, and pancreas beta cell cultures all point to a single threshold at which elevated blood sugars cause permanent damage to your body. What is that level? 140 mg/dl (7.8 mmol/L) after meals You can read in detail about the research that establishes this as the highest level you should allow your blood sugars to rise after meals here: Research Connecting Blood Sugar Level with Organ Damage The AACE Recommends A Post-Meal Blood Sugar Target Below 140 mg/dl In 2007, The American Association of Clinical Endocrinologists, an organization of specialists who treat diabetes, published a White Paper recommending that blood sugar should not be allowed to rise above 140 mg/dl two hours after a meal. The white paper explained this stating: . .a large number of highly robust cross-sectional and prospective epidemiologic studies have clearly implicated a close association between postchallenge or postprandial hyperglycemia and cardiovascular risk. These studies encompass diverse populations and disparate geographic regions, from Honolulu to Chicago to Islington Continue reading >>
What Does 'post-meal (or Post-prandial) Blood Sugar' Mean And What Does It Tell You?
Question:What does 'post-meal (or post-prandial) blood sugar' mean and what does it tell you? Answer:The post-prandial blood sugar is a measure of your blood glucoses after you've eaten. This number is highly variable and dependent on what you've taken in. For example, if you've had a meal that's high in carbohydrate, your blood sugars will go up quickly but may come down more rapidly. If you've had a meal that's high in protein or fat, it may stay up longer but it tends to rise more slowly. When we ask patients to check their blood sugars after they've eaten, we typically will request they check at the two-hour mark, because that's the most consistent time, given the variability of what kind of food they've eaten. We also know that any blood glucose over 180 (mg/dL) at two hours after you've eaten is certainly worrisome, and in fact, our American Diabetes Association goal for your two-hour reading after your meal is less than 180 (mg/dL). The reason this is important is because that is the first thing that we lose when you become diabetic -- that is, the inability for the pancreas to make enough insulin to cover the food.

High Blood Glucose: What It Means And How To Treat It
What is high blood glucose? People who do not have diabetes typically have fasting plasma blood glucose levels that run under 100 mg/dl. Your physician will define for you what your target blood glucose should be — identifying a blood glucose target that is as close to normal as possible that you can safely achieve given your overall medical health. In general, high blood glucose, also called 'hyperglycemia', is considered "high" when it is 160 mg/dl or above your individual blood glucose target. Be sure to ask your healthcare provider what he or she thinks is a safe target for you for blood glucose before and after meals. If your blood glucose runs high for long periods of time, this can pose significant problems for you long-term — increased risk of complications, such as eye disease, kidney disease, heart attacks and strokes and more. High blood glucose can pose health problems in the short-term as well. Your treatment plan may need adjustment if the blood glucose stays over 180 mg/dl for 3 days in a row. It is important to aim to keep your blood glucose under control, and treat hyperglycemia when it occurs. What are the symptoms of high blood glucose? Increased thirst Increased urination Dry mouth or skin Tiredness or fatigue Blurred vision More frequent infections Slow healing cuts and sores Unexplained weight loss What causes high blood glucose? Too much food Too little exercise or physical activity Skipped or not enough diabetes pills or insulin Insulin that has spoiled after being exposed to extreme heat or freezing cold Stress, illness, infection, injury or surgery A blood glucose meter that is not reading accurately What should you do for high blood glucose? Be sure to drink plenty of water. It is recommended to drink a minimum of 8 glasses each day. If yo Continue reading >>
Carbohydrate-last Meal Pattern Lowers Postprandial Glucose And Insulin Excursions In Type 2 Diabetes
Background There are limited data regarding the timing of carbohydrate ingestion during a meal and postprandial glucose regulation. Methods Sixteen subjects with type 2 diabetes mellitus (T2DM) consumed the same meal on 3 days in random order: carbohydrate first, followed 10 min later by protein and vegetables; protein and vegetables first, followed 10 min later by carbohydrate; or all components together. Blood was sampled for glucose, insulin, glucagon-like peptide-1 (GLP-1), and glucagon measurements at baseline (just before meal ingestion) and subsequently at 30 min intervals up to 180 min. Results The incremental areas under the curve for glucose (iAUC0–180) and incremental glucose peaks were 53% and 54% lower, respectively, when carbohydrate was consumed last compared with carbohydrate consumed first (3124.7±501.2 vs 6703.5±904.6 mg/dL×180min, p<0.001; 34.7±4.1 vs 75.0±6.5 mg/dL, p<0.001) and 44% and 40% lower, respectively, compared with the all components together condition (3124.7±501.2 vs 5587.1±828.7 mg/dL×180min, p=0.003; 34.7±4.1 vs 58.2±5.9 mg/dL, p<0.001). Postprandial insulin excursions were lower (iAUC0–180: 7354.1±897.3 vs 9769.7±1002.1 µU/mL×min, p=0.003) and GLP-1 excursions higher (iAUC0–180: 3487.56±327.7 vs 2519.11±494.8 pg/mL×min, p=0.019) following the carbohydrate-last meal order compared with carbohydrate first. Conclusion The carbohydrate-last meal pattern may be an effective behavioral strategy to improve postprandial glycemia.

Diabetes The Basics: Blood Sugars: The Nondiabetic Versus The Diabetic
BLOOD SUGARS: THE NONDIABETIC VERSUS THE DIABETIC Since high blood sugar is the hallmark of diabetes, and the cause of every long-term complication of the disease, it makes sense to discuss where blood sugar comes from and how it is used and not used. Our dietary sources of blood sugar are carbohydrates and proteins. One reason the taste of sugar—a simple form of carbohydrate—delights us is that it fosters production of neurotransmitters in the brain that relieve anxiety and can create a sense of well-being or even euphoria. This makes carbohydrate quite addictive to certain people whose brains may have inadequate levels of or sensitivity to these neurotransmitters, the chemical messengers with which the brain communicates with itself and the rest of the body. When blood sugar levels are low, the liver, kidneys, and intestines can, through a process we will discuss shortly, convert proteins into glucose, but very slowly and inefficiently. The body cannot convert glucose back into protein, nor can it convert fat into sugar. Fat cells, however, with the help of insulin, do transform glucose into fat. The taste of protein doesn’t excite us as much as that of carbohydrate— it would be the very unusual child who’d jump up and down in the grocery store and beg his mother for steak or fish instead of cookies. Dietary protein gives us a much slower and smaller blood sugar effect, which, as you will see, we diabetics can use to our advantage in normalizing blood sugars. The Nondiabetic In the fasting nondiabetic, and even in most type 2 diabetics, the pancreas constantly releases a steady, low level of insulin. This baseline, or basal, insulin level prevents the liver, kidneys, and intestines from inappropriately converting bodily proteins (muscle, vital organs) into g Continue reading >>
Post Prandial Plasma Glucose Level Less Than The Fasting Level In Otherwise Healthy Individuals During Routine Screening
During routine screening, some otherwise healthy individuals who showed remarkably lower post prandial (at 2 hour) plasma glucose without any symptom were subjected to extended glucose tolerance test and a few of them to extended post meal tolerance test as well. It was observed that post prandial (at 2 hour) plasma glucose after glucose administration was significantly lower than the fasting level (p<0.05−p<0.001). However, post prandial plasma glucose at 2 hour after their usual meal exhibited a significantly higher level than the fasting and post glucose level (p<0.05−p<0.001). Glucose appears to be a stronger agent than the more natural mixed meal in these individuals in causing post prandial lowering of plasma glucose. Hence, these individuals are to be evaluated with their usual meals before considering further investigations. Like upper limit, there is the need to have a consensus lower limit of reference interval of blood glucose level.
