How Blood Sugar Affects Your Body
When you have diabetes, your blood sugar (glucose) levels may be consistently high. Over time, this can damage your body and lead to many other problems. How much sugar in the blood is too much? And why is high glucose so bad for you? Here’s a look at how your levels affect your health. They're less than 100 mg/dL after not eating (fasting) for at least 8 hours. And they're less than 140 mg/dL 2 hours after eating. During the day, levels tend to be at their lowest just before meals. For most people without diabetes, blood sugar levels before meals hover around 70 to 80 mg/dL. For some people, 60 is normal; for others, 90. What's a low sugar level? It varies widely, too. Many people's glucose won't ever fall below 60, even with prolonged fasting. When you diet or fast, the liver keeps your levels normal by turning fat and muscle into sugar. A few people's levels may fall somewhat lower. Doctors use these tests to find out if you have diabetes: Fasting plasma glucose test. The doctor tests your blood sugar levels after fasting for 8 hours and it’s higher than 126 mg/dL. Oral glucose tolerance test. After fasting for 8 hours, you get a special sugary drink. Two hours later your sugar level is higher than 200. Random check. The doctor tests your blood sugar and it’s higher than 200, plus you’re peeing more, always thirsty, and you’ve gained or lost a significant amount of weight. He’ll then do a fasting sugar level test or an oral glucose tolerance test to confirm the diagnosis. Any sugar levels higher than normal are unhealthy. Levels that are higher than normal, but not reaching the point of full-blown diabetes, are called prediabetes. According to the American Diabetes Association, 86 million people in the U.S. have this condition, which can lead to diabetes Continue reading >>
What Are Normal Blood Glucose Levels?
If you get a physical every year, chances are that your doctor orders a blood test that will tell you, among other things, if your blood sugar level is “normal.” If it’s not, you may have diabetes, or be at risk for it in coming years. But what’s this strange thing called “normal” anyway? There’s two main ways to measure blood glucose, depending on where you’re located. If you’re in Europe: In Europe, blood sugar is measured using millimoles per litre. A “normal” blood glucose level comes in at around 4 – 7 mmol/L or 4 – 8 mmol/L for a child with Type 1 diabetes before meals. Two hours after a meal, a normal blood sugar range should be under 9 mmol/L for people with T1D. For T2D, the upper range is slightly lower at 8.5 mmol/L. You can find additional information on the Diabetes UK website. If you’re in the US: The clinical definition puts “normal” blood glucose at 70-120 mg/dL (milligrams per decilitre) if you’ve fasted eight to twelve hours, or 70-160 mg/dL if you did not fast. That probably makes perfect sense if you have “M.D.” after your name. If you don’t, here’s the translation: 70 to 120 milligrams per deciliter. Clear as … uh…. blood, right? Don’t worry, it’s just the mathematics of measuring density. Here’s an easier way to remember ideal levels, courtesy of doctor Mehmet Oz: Optimal blood glucose is less than 100 after a fast, less than 125 if you weren’t fasting. But even then, remember, glucose levels are like the tide, constantly ebbing and flowing, depending on when – and what – we last ate. What is blood glucose anyway? Blood glucose means the same thing as blood sugar. But ironically enough, the amount of sugars coursing through our blood is not based on our intake of sugar, but how many carbohyd 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.

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. These Continue reading >>
Blood Sugar Test
A blood glucose test measures the amount of a sugar called glucose in a sample of your blood. Glucose is a major source of energy for most cells of the body, including brain cells. Carbohydrates are found in fruit, cereal, bread, pasta, and rice. They are quickly turned into glucose in your body. This raises your blood glucose level. Hormones made in the body help control blood glucose level. Continue reading >>
Fasting Blood Sugar: Normal Levels And Testing
Fasting blood sugar provides vital clues about how the body is managing blood sugar levels. Blood sugar tends to peak about an hour after eating, and declines after that. High fasting blood sugar levels point to insulin resistance or diabetes. Abnormally low fasting blood sugar could be due to diabetes medications. Knowing when to test and what to look for can help keep people with, or at risk of, diabetes healthy. What are fasting blood sugar levels? Following a meal, blood sugar levels rise, usually peaking about an hour after eating. How much blood sugar rises by and the precise timing of the peak depends on diet. Large meals tend to trigger larger blood sugar rises. High-sugar carbohydrates, such as bread and sweetened snacks, also cause more significant blood sugar swings. Normally, as blood sugar rises, the pancreas releases insulin. Insulin lowers blood sugar, breaking it down so that the body can use it for energy or store it for later. However, people who have diabetes have difficulties with insulin in the following ways: People with type 1 diabetes do not produce enough insulin because the body attacks insulin-producing cells. People with type 2 diabetes do not respond well to insulin and, later, may not make enough insulin. In both cases, the result is the same: elevated blood sugar levels and difficulties using sugar. This means that fasting blood sugar depends on three factors: the contents of the last meal the size of the last meal the body's ability to produce and respond to insulin Blood sugar levels in between meals offer a window into how the body manages sugar. High levels of fasting blood sugar suggest that the body has been unable to lower the levels of sugar in the blood. This points to either insulin resistance or inadequate insulin production, an 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 >>
What Is The Normal Range For Blood Sugar Levels, And What Blood Sugar Level Constitutes A True Emergency?
Yahoo!-ABC News Network | 2018 ABC News Internet Ventures. All rights reserved. What Is The Normal Range For Blood Sugar Levels, And What Blood Sugar Level Constitutes A True Emergency? CLINICAL RESEARCH AT JOSLIN DIABETES CENTER, 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 associa 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 >>
Random Blood Glucose Test
RATE★★★★★ A random blood glucose test is used to diagnose diabetes. The test measures the level of glucose (a type of sugar) in your blood. If your blood glucose level is 200 mg/dL or higher and you have the classic symptoms of high blood sugar (excessive thirst, urination at night, blurred vision and, in some cases, weight loss) your doctor may diagnose you with diabetes. If you do not have any symptoms of high blood sugar, your doctor will probably have you take another test for further evidence of diabetes.1 Usually, having high blood glucose can be a sign that your body is not functioning normally and that you may have diabetes. If you have high blood glucose and it is not treated, it can lead to serious health complications. However, finding out that your blood glucose is elevated is powerful information that you can use to keep yourself healthy. If you know that your blood glucose is high, you can take steps to lower it, by losing weight (if you are overweight or obese), getting regular moderate physical activity, and taking a medication that lowers blood glucose.2 Why measuring blood glucose is important in diagnosing type 2 diabetes Our bodies require energy to function properly and we get that energy from the foods we eat. Our diet (everything we eat and drink) includes three main sources of energy (also known as calories): protein, fat, and carbohydrates (sugars, starches, and fibers).When the body digests most sources of carbohydrates, they are transformed through digestion into a very important source of instant energy, a form of sugar called glucose. Our bodies depend on the action of a number of different natural body chemicals called hormones, including insulin, amylin, incretins, and glucagon, working together in conjunction, to control how we Continue reading >>

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 >>
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 >>
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 >>
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 >>
