Normal Blood Glucose
[Science of Diabetes] One of the most common questions asked by people with diabetes is: "What are normal blood sugar levels?" Unfortunately, there’s no simple answer to this question, because it depends on how you define normal. It’s like deciding when someone is rich or poor, tall or short, thin or fat, or young or old. Most people would agree that a very skinny person was thin and a very fat person was fat. But how about the sizes in between? When does underweight become normal and when does normal become overweight? It’s all a matter of definitions and cutoff points set by one group or another. The definitions of normal, prediabetes, and diabetes are usually made by august committees of diabetes experts, and they change from time to time. For example, not too long ago, it was decided that you’re diabetic if your fasting BG level is 126 mg/dL [to convert to mMol/L, divide by 18] or higher, instead of the previous cutoff of 140. There are some guidelines about "nondiabetic" BG levels, for instance, "Nondiabetics never go over 140 mg/dL, no matter what they eat, and return to premeal levels in 2 or 3 hours" or "Nondiabetic fasting levels are 70 to 100 mg/dL." Textbooks that plot BG levels during the day in diabetic and nondiabetic individuals often show the nondiabetic levels as ranging from about 80 mg/dL before meals to close to 100 after some meals and about 120 after the largest meal of the day. However, real life doesn’t always correspond to the textbooks. Some nondiabetic people, especially young, fit persons, keep their BG levels much more stable than that. Many people with diabetes have used their home meters to measure their nondiabetic spouses and friends. Some find that the nondiabetic family members stay in the 80s no matter what they eat. Others Continue reading >>

Are We All Pre-diabetic?
Even if a doctor assures you that your blood sugar is "normal," alarming evidence documents that you are at significant risk of premature death unless you achieve optimal 24-hour-a-day glucose control. Life Extension® long ago warned of the silent dangers when fasting blood sugar exceeds 85 mg/dL. New scientific studies validate this position. Even more insidious are data showing that blood sugar "spikes" that occur after each meal dramatically increase the risk of cardiovascular disease, retinal damage, and cancer. Unless steps are taken to suppress after-meal sugar surges, every large meal you eat can trigger a dangerous metabolic cascade that results in cell damage and accelerated aging. Fortunately, proven methods exist to support optimal blood sugar throughout the day. The latest is a green coffee bean extract that targets a critical enzyme involved in after-meal blood sugar spikes. When tested on humans in a placebo-controlled study, this natural extract produced an astounding 32% drop in after-meal blood sugar!1 An Epidemic of Elevated Blood Sugar The percentage of adults who suffer chronic high blood sugar is staggering! One report evaluated 46,000 middle-age individuals and found more than 80% had fasting blood sugar of 85 mg/dL or greater.2 Another study involving 11,000 middle-age and older individuals showed more than 85% had fasting blood sugar of 85 mg/dL or greater.3 Since incidence of disease starts to increase when fasting blood sugar rises above these levels, this means the vast majority of aging humans today endure chronic cellular damage associated with elevated blood sugar. This epidemic of elevated blood sugar will accelerate age-related disease until the medical profession realizes that their test values for defining "normal" blood sugar are horr 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 >>
Managing Your Blood Sugar
Know the basic steps for managing your diabetes. Poorly managed diabetes can lead to many health problems. Know how to: Monitor your blood sugar (glucose) Find, buy, and store diabetes supplies If you take insulin, you should also know how to: Give yourself insulin Adjust your insulin doses and the foods you eat to manage your blood sugar during exercise and on sick days You should also live a healthy lifestyle. Exercise at least 30 minutes a day, 5 days a week. Do muscle strengthening exercises 2 or more days a week. Avoid sitting for more than 30 minutes at a time. Try speed walking, swimming, or dancing. Pick an activity you enjoy. Always check with your doctor before starting any new exercise plans. Follow your meal plan. Take your medicines the way your health care provider recommends. Checking your blood sugar levels often and writing down the results will tell you how well you are managing your diabetes. Talk to your doctor and diabetes educator about how often you should check your blood sugar. Not everyone with diabetes needs to check their blood sugar every day. But some people may need to check it many times a day. If you have type 1 diabetes, check your blood sugar at least 4 times a day. Usually, you will test your blood sugar before meals and at bedtime. You may also check your blood sugar: After you eat out, especially if you have eaten foods you don't normally eat If you feel sick Before and after you exercise If you have a lot of stress If you eat too much If you are taking new medicines Keep a record for yourself and your provider. This will be a big help if you are having problems managing your diabetes. It will also tell you what works and what doesn't work, to keep your blood sugar under control. Write down: The time of day Your blood sugar level Th Continue reading >>
What Is The Normal Range For Blood Sugar Levels, And What Blood Sugar Level Constitutes A True Emergency?
Question:What is the normal range for blood sugar levels, and what blood sugar level constitutes a true emergency? Answer:Now, in a normal individual we measure blood sugar under different circumstances. What we call fasting blood sugar or blood glucose levels is usually done six to eight hours after the last meal. So it's most commonly done before breakfast in the morning; and the normal range there is 70 to 100 milligrams per deciliter. Now when you eat a meal, blood sugar generally rises and in a normal individual it usually does not get above a 135 to 140 milligrams per deciliter. So there is a fairly narrow range of blood sugar throughout the entire day. Now in our diabetic patients we see both low blood sugar levels that we call hypoglycemia, or elevated blood sugars, hyperglycemia. Now, if the blood sugar drops below about 60 or 65 milligrams per deciliter, people will generally get symptoms, which are some shakiness, feeling of hunger, maybe a little racing of the heart and they will usually be trenchant or if they eat something, it goes away right away. But if blood sugar drops below 50 and can get down as low as 40 or 30 or even 20, then there is a progressive loss of mental function and eventually unconsciousness and seizures. And of course that is very dangerous and a medical emergency. On the other side, if blood sugar gets up above 180 to 200, then it exceeds the capacity of the kidneys to reabsorb the glucose and we begin to spill glucose into the urine. And if it gets way up high, up in the 400s or even 500s, it can be associated with some alteration in mental function. And in this situation, if it persists for a long time, we can actually see mental changes as well. So either too low or very exceedingly high can cause changes in mental function.

What Is Normal Blood Sugar?
Thank you for visiting my website! If you need help lowering your blood sugar level, check out my books at Amazon or Smashwords. If you’re outside of the U.S., Smashwords may be the best source. —Steve Parker, M.D. * * * Physicians focus so much on disease that we sometimes lose sight of what’s healthy and normal. For instance, the American Diabetes Association defines “tight” control of diabetes to include sugar levels as high as 179 mg/dl (9.94 mmol/l) when measured two hours after a meal. In contrast, young adults without diabetes two hours after a meal are usually in the range of 90 to 110 mg/dl (5.00–6.11 mmol/l). What Is a Normal Blood Sugar Level? The following numbers refer to average blood sugar (glucose) levels in venous plasma, as measured in a lab. Portable home glucose meters measure sugar in capillary whole blood. Many, but not all, meters in 2010 are calibrated to compare directly to venous plasma levels. Fasting blood sugar after a night of sleep and before breakfast: 85 mg/dl (4.72 mmol/l) One hour after a meal: 110 mg/dl (6.11 mmol/l) Two hours after a meal: 95 mg/dl (5.28 mmol/l) Five hours after a meal: 85 mg/dl (4.72 mmol/l) (The aforementioned meal derives 50–55% of its energy from carbohydrate) ♦ ♦ ♦ Ranges of blood sugar for young healthy non-diabetic adults: Fasting blood sugar: 70–90 mg/dl (3.89–5.00 mmol/l) One hour after a typical meal: 90–125 mg/dl (5.00–6.94 mmol/l) Two hours after a typical meal: 90–110 mg/dl (5.00–6.11 mmol/l) Five hours after a typical meal: 70–90 mg/dl (3.89–5.00 mmol/l) Blood sugars tend to be a bit lower in pregnant women. ♦ ♦ ♦ What Level of Blood Sugar Defines Diabetes and Prediabetes?

10 Surprising Causes Of Blood Sugar Swings You Probably Didn’t Know
1 / 11 What Causes Blood Sugar to Rise and Fall? Whether you were recently diagnosed with type 2 diabetes or have been living with the disease for several years, you know how fickle blood sugar levels can be, and how important it is that they stay controlled. Proper blood sugar control is key for helping ward off potential diabetes complications, such as kidney disease, nerve damage, vision problems, stroke, and heart disease, according to the National Institutes of Health (NIH). If you keep your levels in check on a daily basis, it will help you stay energized, focused, and in a good mood. You’ll know if your diabetes is poorly controlled if you experience symptoms such as frequent urination, sores that won’t heal, blurred vision, and unexplained weight loss. According to the American Diabetes Association (ADA), proper medication, effective meal planning, regular exercise, and use of a blood glucose meter to track your numbers routinely can all help you keep your levels within a healthy range. The ADA recommends blood glucose be 80 to 130 milligrams per deciliter (mg/dL) before meals, and below 180 mg/dL two hours after the start of a meal. Furthermore, the organization recommends getting an A1C test, which measures your average blood glucose over the past two to three months, at least twice per year if your levels are stable and you are meeting treatment goals. Learning how different habits can cause your blood sugar to fluctuate can help you better predict how your levels will swing. You may be more likely to experience hypoglycemia, or low blood sugar if you have advanced-stage diabetes, according to the ADA. Meanwhile, high blood sugar, or hyperglycemia, may be caused by factors such as not using enough insulin or other diabetes medication, not following a prop Continue reading >>
Why Blood Sugar Levels Rise Overnight
get the scoop When you go to bed, your blood sugar reading is 110, but when you wake up in the morning, it has shot up to 150. Why does this happen? To understand how blood sugar levels can rise overnight without your eating anything, we have to look at where glucose comes from — and where it goes — while we sleep. During the day, the carbohydrates we eat are digested into glucose and absorbed into the bloodstream. Some of this glucose goes to the liver, where it is stored for later use. At night, while we are asleep, the liver releases glucose into the bloodstream. The liver acts as our glucose warehouse and keeps us supplied until we eat breakfast. The amount of glucose being used is matched by the amount of glucose being released by the liver, so blood sugar levels should remain constant. what is the dawn phenomenon? A rise in blood sugar level between approximately 3 A.M. and the time you wake up is called the “dawn phenomenon.” The liver is supposed to release just enough glucose to replace what is being used, and insulin works as the messenger to tell the liver how much is enough. But if there's not enough insulin (as with type 1 diabetes), or if there's enough insulin but it cannot communicate its message to the liver (as with type 2 diabetes), the liver starts to release glucose much too quickly. In addition, levels of hormones such as cortisol begin to increase in the early morning hours, which can contribute to altered insulin sensitivity. The result? Blood sugar levels rise. This is why blood sugar levels can go up between the time you go to bed and the time you wake up. what can you do about it? You might be able to make changes in the timing of your meals, medications, or insulin injections to help prevent dawn phenomenon. First, keep a detailed rec 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 >>
How Much Should Sugars Fluctuate Before & After Meals?
Everyone’s blood sugar, or blood glucose levels, will fluctuate throughout the day. The main factors that affect blood sugar include what and how much you eat and how long it’s been since your last meal. Activity level, stress, infection or illness can also affect glucose levels. Generally, your blood sugar is lowest when you’ve fasted overnight, or for at least eight hours, and highest within an hour or two after eating foods that are high in carbohydrates. Blood glucose can be measured by a blood test in a lab or from a finger stick and a glucose meter. A normal blood glucose reading after fasting overnight is between 70 and 100 milligrams per deciliter. Most healthy people's blood sugar will be within this range for most of the day and night because the body’s hormones insulin and glucagon work to keep glucose from going too high or low. On the High End If your blood glucose is checked after you’ve eaten, it may be higher, but how high depends on what you ate and how long it’s been since you ate. Foods that are rich in carbohydrates, like breads, pasta, potatoes, sugary drinks or desserts, will raise blood sugar the highest. Blood sugar goes up for an hour or two after you eat, and then it starts to return to normal. Even after meals, a healthy person’s blood sugar is usually less than 140 mg/dl. If It’s Too High Blood glucose levels that are too high may mean you have prediabetes or diabetes. Prediabetes, also know as impaired fasting glucose, is diagnosed when your fasting blood glucose is higher than the normal range and between 100 and 125 mg/dl. This increases the risk of diabetes. A diagnosis of diabetes is made if fasting blood glucose is over 126 mg/dl or you have two random glucose measurements over 200 mg/dl. Occasionally, medical problems o Continue reading >>

What Is Normal Blood Sugar Level
The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or an animal. The body naturally tightly regulates blood glucose levels (with the help of insulin that is secreted by pancreas) as a part of metabolic homeostasis. If blood sugar levels are either increased or decreased by a greater margin than expected this might indicate a medical condition. Diabetic patients must monitor their blood sugar levels as body’s inability to properly utilize and / or produce insulin can pose a serious threat to their health.

Accessories Diabetic Socks Diabetic Shoes What is blood sugar? What does it mean when someone refers to blood sugar level in your body? Blood sugar level (or blood sugar concentration) is the amount of glucose (a source of energy) present in your blood at any given time. A normal blood glucose level for a healthy person is somewhere between 72 mg/dL (3.8 to 4 mmol/L) and 108 mg/dL (5.8 to 6 mmol/L). It, of course, depends on every individual alone. Blood sugar levels might fluctuate due to other reasons (such as exercise, stress and infection). Typically blood sugar level in humans is around 72 mg/dL (or 4 mmol/L). After a meal the blood sugar level may increase temporarily up to 140 mg/dL (7.8 mmol/L). This is normal. A blood sugar level between 72 mg/dL (4 mmol/L) and 108 mg/dL (6 mmol/L) is considered normal for a h Continue reading >>
What Are The Ideal Levels Of Blood Sugar?
A blood sugar or blood glucose chart identifies ideal blood sugar levels throughout the day, including before and after meals. Doctors use blood sugar charts to set target goals and monitor diabetes treatment plans. Blood sugar charts also help those with diabetes assess and self-monitor blood sugar test results. What is a blood sugar chart? Blood sugar charts act as a reference guide for blood sugar test results. As such, blood sugar charts are important tools for diabetes management. Most diabetes treatment plans involve keeping blood sugar levels as close to normal or target goals as possible. This requires frequent at-home and doctor-ordered testing, along with an understanding of how results compare to target levels. To help interpret and assess blood sugar results, the charts outline normal and abnormal blood sugar levels for those with and without diabetes. In the United States, blood sugar charts typically report sugar levels in milligrams per deciliter (mg/dL). In the United Kingdom and many other countries, blood sugar is reported in millimoles per liter (mmol/L). A1C blood sugar recommendations are frequently included in blood sugar charts. A1C results are often described as both a percentage and an average blood sugar level in mg/dL. An A1C test measures the average sugar levels over a 3-month period, which gives a wider insight into a person's overall management of their blood sugar levels. Blood sugar chart guidelines Appropriate blood sugar levels vary throughout the day and from person to person. Blood sugars are often lowest before breakfast and in the lead up to meals. Blood sugars are often highest in the hours following meals. People with diabetes will often have higher blood sugar targets or acceptable ranges than those without the condition.

Blood Glucose Levels
What is the blood sugar level? The blood sugar level is the amount of glucose (sugar) in the blood. It is also known as plasma glucose level. It is expressed as millimoles per litre (mmol/l). Normally blood glucose levels stay within narrow limits throughout the day: 4 to 8mmol/l. But they are higher after meals and usually lowest in the morning. In diabetes the blood sugar level moves outside these limits until treated. Even with good control of diabetes, the blood sugar level will still at times drift outside this normal range. Why control blood sugar levels? When very high levels of blood glucose are present for years, it leads to damage of the small blood vessels. This in turn increases your risk of developing late-stage diabetes complications including: With type 1 diabetes, these complications may start to appear 10 to 15 years after diagnosis. They frequently appear less than 10 years after diagnosis of type 2 diabetes, because this type of diabetes is often present for years before it is recognised. By keeping the blood sugar level stable, you significantly reduce your risk of these complications. How can I measure blood sugar levels? Home testing kits come in a variety of shapes and sizes. A pharmacist or the diabetes clinic nurse can advise you about the best model. You can usually obtain a blood glucose meter at little or no cost via the diabetes clinic. Testing strips are available on NHS prescription. You can learn to measure blood sugar levels simply and quickly with a home blood glucose level testing kit. All kits have at least two things: a measuring device (a 'meter') and a strip. To check your blood sugar level, put a small amount of blood on the strip. Now place the strip into the device. Within 30 seconds it will display the blood glucose level. The Continue reading >>
This information describes diabetes, the complications related to the disease, and how you can prevent these complications. Blood Sugar Control Diabetes is a disease where the blood sugar runs too high, usually due to not enough insulin. It can cause terrible long-term complications if it is not treated properly. The most common serious complications are blindness ("retinopathy"), kidney failure requiring dependence on a dialysis machine to stay alive ("nephropathy"), and foot and leg amputations. The good news is that these complications can almost always be prevented if you keep your blood sugar near the normal range. The best way to keep blood sugar low is to eat a healthy diet and do regular exercise. Just 20 minutes of walking 4 or 5 times a week can do wonders for lowering blood sugar. Eating a healthy diet is also very important. Do your best to limit the number of calories you eat each day. Put smaller portions of food on your plate and eat more slowly so that your body has a chance to let you know when it's had enough to eat. It is also very important to limit saturated fats in your diet. Read food labels carefully to see which foods are high in saturated fats. Particular foods to cut down on are: whole milk and 2% milk, cheese, ice cream, fast foods, butter, bacon, sausage, beef, chicken with the skin on (skinless chicken is fine), doughnuts, cookies, chocolate, and nuts. Often, diet and exercise alone are not enough to control blood sugar. In this case, medicine is needed to bring the blood sugar down further. Often pills are enough, but sometimes insulin injections are needed. If medicines to lower blood sugar are started, it is still very important to keep doing regular exercise and eating a healthy diet.

What Is Normal Blood Sugar?
Blood sugar, or glucose, is an important source of energy and provides nutrients to your body's organs, muscles and nervous system. The body gets glucose from the food you eat, and the absorption, storage and production of glucose is regulated constantly by complex processes involving the small intestine, liver and pancreas. Normal blood sugar varies from person to person, but a normal range for fasting blood sugar (the amount of glucose in your blood six to eight hours after a meal) is between 70 and 100 milligrams per deciliter. For most individuals, the level of glucose in the blood rises after meals. A normal blood-sugar range after eating is between 135 and 140 milligrams per deciliter. These variations in blood-sugar levels, both before and after meals, are normal and reflect the way that glucose is absorbed and stored in the body. After you eat, your body breaks down the carbohydrates in food into smaller parts, including glucose, which can be absorbed by the small intestine. As the small intestine absorbs glucose, the pancreas releases insulin, which stimulates body tissues and causes them to absorb this glucose and metabolize it (a process known as glycogenesis). This stored glucose (glycogen) is used to maintain healthy blood-sugar levels between meals. When glucose levels drop between meals, the body takes some much-needed sugar out of storage. The process is kicked off by the pancreas, which releases a hormone known as glucagon, which promotes the conversion of stored sugar (glycogen) in the liver back to glucose. The glucose is then released into the bloodstream. When there isn't enough glucose stored up to maintain normal blood-sugar levels, the body will even produce its own glucose from noncarbohydrate sources (such as amino acids and glycerol). This pro Continue reading >>
