Normal Blood Sugar Goals And Why 3
My blood sugar goals: truly normal blood sugars. In other words, normal blood sugar for non-diabetics. It’s common sense right? Who would want ab-normal blood sugar levels? The devil is in the details. What are truly normal blood sugar ranges What happens when you exceed normal ranges Our bodies are designed to maintain a very tight range of glucose in our blood. If we exceed a certain level, insulin is secreted. If we go below certain levels, glucose is secreted. Why is our body designed to maintain such a tight range of blood sugar levels? Elevated blood sugars, hyperglycemia is toxic to every cell Truly low blood sugars , hypoglycemia can lead to death Note: I will periodically update a list at the end of this post with studies showing the advantages of maintaining ‘truly’ normal blood sugars. These studies are under the ‘Additional References” section. Complications of Elevated Blood Sugar We know that diabetes related complications occur at higher levels of blood sugar. High blood sugar is toxic to every cell in the body. Toxic levels of blood sugar harm all of our cells and our organs. This toxicity causes retinopathy, neuropathy, organ failure, amputations, heart disease, etc. Why in the hell would I want diabetic blood sugar levels? Our bodies are designed to run at a certain narrow blood sugar range. I want that range. Below we will look at studies showing the effects not ‘just’ for diabetic levels of blood sugar, but for higher levels of so-called normal blood sugar ranges. Blood Sugar and Dementia In this Article, “Dementia risk tied to blood sugar level, even with no diabetes” “A Joint Group Health-University of Washington (UW) study in the New England Journal of Medicine has found that higher blood sugar levels are associated with higher Continue reading >>
* What Is A Normal Blood Sugar?
Normal blood sugars after a high carbohydrate breakfast eaten at 7:30 AM. The blue line is the average for the group. The brown lines show the range within which most readings fell (2 standard deviations). Bottom lines show Insulin and C-peptide levels at the same time. Click HERE if you don't see the graph. Graph is a screen shot from Dr. Christiansen's presentation cited below. The term "blood sugar" refers to the concentration of glucose, a simple, sugar, that is found in a set volume of blood. In the U.S. it is measured in milligrams per deciliter, abbreviated as mg/dl. In most of the rest of the world it is measured in millimoles per liter, abbreviated as mmol/L. The concentration of glucose in our blood changes continually throughout the day. It can even vary significantly from minute to minute. When you eat, it can rise dramatically. When you exercise it will often drop. The blood sugar measures that doctors are most interested in is the A1c, discussed below. When you are given a routine blood test doctors usually order a fasting glucose test. The most informative blood sugar reading is the post-meal blood sugar measured one and two hours after eating. Doctors rarely test this important blood sugar measurement as it is time consuming and hence expensive. Rarely doctors will order a Oral Glucose Tolerance Test, which tests your response to a huge dose of pure glucose, which hits your blood stream within minutes and produces results quite different from the blood sugars you will experience after each meal. Below you will find the normal readings for these various tests. Normal Fasting Blood Sugar Fasting blood sugar is usually measured first thing in the morning before you have eaten any food. A truly normal fasting blood sugar (which is also the blood sugar a norm Continue reading >>
How To Tell When Normal Blood Sugar Isn’t
Most people don’t worry about diabetes until a doctor tells them their blood sugar is too high. But even if you get a “normal” blood sugar reading at your next exam, you might not be totally in the clear. According to cutting-edge research, blood sugar levels on the high end of the normal range may still raise your risk of illness, leading some doctors to take such results more seriously — particularly if patients have other diabetes risk factors, such as obesity or family history. The somewhat arbitrary cutoff between normal blood sugar levels and higher ones associated with diabetes may give a false sense of security to millions of people, notes brain researcher Nicolas Cherbuin of Australian National University. His research published in 2013 found that middle-aged people with high-normal fasting blood sugar readings had worse scores on memory tests and more shrinkage in a brain region important to memory than those with lower blood sugar. Higher glucose levels may damage blood vessels and hinder the flow of nutrients to the brain. THE NUMBERS YOU AND YOUR DOC SHOULD KNOW • DIABETES: Blood sugar level of 126 mg/dl or higher • PREDIABETES: Blood sugar level between 100 and 125 mg/dl • HIGH-NORMAL BLOOD SUGAR: Roughly 90 to 99 mg/dl (a new category being studied for health risks) • NORMAL BLOOD SUGAR: Currently defined as 70 to 99 mg/dl * All levels are based on a fasting blood glucose test, which involves an overnight fast. Other research suggests high-normal blood sugar may increase your heart disease risk by raising inflammation and making blood vessels stiffer. A 2012 Israeli study found that people with a fasting blood sugar between 90 and 99 mg/dl were 40 percent more likely to suffer heart disease than those with a level under 80 mg/dl. Cancer is Continue reading >>
An Ideal Blood Sugar Range
According to the International Diabetes Federation, a normal blood sugar range for people without diabetes and who are not fasting should be between 82 mg/dL (4.4 mmol/L) and 110 mg/dL (6.1 mmol/L) with 82 mg/dl being optimal. The reason that blood sugar is typically expressed as a range is because it is highly individual and it fluctuates throughout the day based on what you eat, how much exercise you get, your genetics, how old you are and due to certain medical conditions like adrenal fatigue. When it comes to blood sugar, it is just as important to know how high your blood sugar goes after a meal as it is to know what your typical blood sugar range is before meals For this reason, to get a good idea regarding what range your blood sugar typically fluctuates between, it is best to test your blood at the following times: First thing in the morning before your first meal Before eating 1/2 hour after eating 1 hour after eating 2 hours after eating. Normal Blood Sugar Range Based on information from a variety of sources like the American Diabetes Association, the International Diabetes Federation, and the National Institute for Clinical Excellence (NICE). Fasting range between 70 and 100 mg/dL (3.9 to 5.6 mmol/L ) Optimal non-fasting range before a meal is less than 100 mg/dL (5.5 mmol/L ) When operating normally the body restores blood sugar levels to a range of 82 to 110 mg/dL (4.4 to 6.1 mmol/L) within two hours after eating Shortly after a meal your blood glucose level may rise temporarily up to 140 mg/dL (7.8 mmol/L) but should not exceed 180 mg/dL (10 mmol/L) Diabetic Blood Sugar Range The American Diabetes Association recommends that diabetics keep their blood sugar within the following ranges: A1C: 7% or eAG of 154 mg/dL Blood Test result of 70-130 mg/dL before a Continue reading >>
Are My Blood Glucose Levels Normal?
I recently had a blood test for sugar content after fasting. The glucose level was 6.3, but I am not sure what this means. Am I right in assuming that a normal level after fasting for 12 hours is between 4.2 and 6.2, (which presumably means I am on the diabetes borderline)? Advice would be greatly appreciated. I wonder why you decided to check your fasting glucose level . Do you have a family history of diabetes? Perhaps you are taking medication, such as a steroid, that can bring on diabetes? We diagnose diabetes mellitus on the criteria of fasting blood glucose level in excess of 7.7 mmol/litre or non-fasting levels above 11.1mmol/litre. However, the body may develop a reduced ability to handle glucose some for time before diabetes manifests. This probably occurs as people become obese and thereby become resistant to the effects of their own insulin which lowers blood glucose. A fasting glucose between 6.0 to 7.7mmol/L falls within the range that doctors would suspect 'impaired glucose tolerance'. We would follow-up your case to discuss your full medical and family history, then arrange for a repeat test called a modified glucose tolerance test. We would also discuss lifestyle and diet since I note that you are a bit heavier than the ideal for your height. Almost all 'maturity-onset' non-insulin diabetes (Type 2 diabetes non-insulin dependent diabetes) is related to increasing obesity.

Diabetes In Pregnancy
Gestational diabetes does not increase the risk of birth defects or the risk that the baby will be diabetic at birth. Also called gestational diabetes mellitus (GDM), this type of diabetes affects between 3% and 20% of pregnant women. It presents with a rise in blood glucose (sugar) levels toward the end of the 2nd and 3rd trimester of pregnancy. In 90% if cases, it disappears after the birth, but the mother is at greater risk of developing type 2 diabetes in the future. Cause It occurs when cells become resistant to the action of insulin, which is naturally caused during pregnancy by the hormones of the placenta. In some women, the pancreas is not able to secrete enough insulin to counterbalance the effect of these hormones, causing hyperglycemia, then diabetes. Symptoms Pregnant women generally have no apparent diabetes symptoms. Sometimes, these symptoms occur: Unusual fatigue Excessive thirst Increase in the volume and frequency of urination Headaches Importance of screening These symptoms can go undetected because they are very common in pregnant women. Women at risk Several factors increase the risk of developing gestational diabetes: Being over 35 years of age Being overweight Family members with type 2 diabetes Having previously given birth to a baby weighing more than 4 kg (9 lb) Gestational diabetes in a previous pregnancy Belonging to a high-risk ethnic group (Aboriginal, Latin American, Asian or African) Having had abnormally high blood glucose (sugar) levels in the past, whether a diagnosis of glucose intolerance or prediabetes Regular use of a corticosteroid medication Suffering from ancanthosis nigricans, a discoloration of the skin, often darkened patches on the neck or under the arms Screening The Canadian Diabetes Association 2013 Clinical Practice Gui Continue reading >>
Normal Blood Sugars In Pregnancy
I have until now avoided discussing the issue of what normal blood sugars should be in pregnancy because it looked like gynecologists were being more aggressive with blood sugar control during pregnancy then other doctors. Blood sugar control is particularly important in pregnancy because a fetus that is exposed to continually high blood sugars will experience significant changes in the way that its genes express which will affect its blood sugar metabolism for the rest of its life. High blood sugar will also make babies very large, which poses problems when it is time for delivery, some life-threatening. Blood sugars are lower in pregnant women because there is a higher blood volume during pregnancy, but it is starting to look like the targets gynecologists have been recommending, which would have been excellent for non-diabetic women are considerably higher than normal. This was made clear by a new meta-study that analyzed a series of studies of the blood sugars of a wide range of normal pregnant women using Continuous Glucose Monitoring, home testing, and hospital lab results. It makes it clear that the current targets for pregnancy are probably too high. Here is the full text version of the meta-study: Patterns of Glycemia in Normal Pregnancy: Should the current therapeutic targets be challenged? Teri L. Hernandez, et al. Diabetes Care July 2011 vol. 34 no. 7 1660-1668. It concludes that the following appear to be truly normal blood sugars for pregnant women: AVERAGE BLOOD SUGARS IN NORMAL PREGNANT WOMEN Fasting: 70.9 ± 7.8 mg/dl (3.94 mmol/L ± .43) One Hour Post Meal: 108.9 ± 12.9 mg/dl (6.05 ± .72 mmol/L) Two Hours Post Meal: 99.3 ±10.2 mg/dl (5.52 ± .57 mmol/L ) A commentary published in this month's Diabetes Care gives more insight into the importance of t 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 >>
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. Trinity Health is a Catholic health care organization that acts in accordance with the Catholic tradition and does not condone or support all practices covered in this site. In case of emergency call 911. This site is educational and not a substitute for professional medical advice, always seek the advice of a qualified healthcare provider. 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 >>
Blood Sugar Normal Values
Blood sugar fluctuations Blood sugar levels are tightly regulated by a variety of stimulations and mechanisms. This is important for metabolic homeostasis. Levels may fluctuate after fasting for long periods of time or an hour or two after consumption of food. Despite this, the fluctuations are minor. Normal human blood glucose levels remains within a remarkably narrow range. In most humans this varies from about 82 mg/dl to 110 mg/dl (4.4 to 6.1 mmol/l). The blood sugar levels rises to nearly 140 mg/dl (7.8 mmol/l) or a bit more in normal humans after a full meal. In humans normal blood glucose levels are around 90 mg/dl, equivalent to 5mM (mmol/l). Since the molecular weight of glucose, C6H12O6, is about 180 g/mol, when calculated the total amount of glucose normally in circulating human blood is around 3.3 to 7g (assuming an ordinary adult blood volume of 5 litres). In other words in a healthy adult male of 75 kg (165 lb) with a blood volume of 5 litres (1.3 gal), a blood glucose level of 100 mg/dl or 5.5 mmol/l means a total of about 5 g (0.2 oz or 0.002 gal, 1/500 of the total) of glucose in the blood. This also means approximately 45 g (1½ ounces) in the total body water. Total body water includes more than merely blood and will be usually about 60% of the total body weight in men. 5 grams of glucose is about equivalent to a small sugar packet or a teaspoon full of sugar. To be considered a non-diabetic the American Diabetes Association recommends a post-meal glucose level less than 180 mg/dl (10 mmol/l) and a pre-meal blood glucose level of 90-130 mg/dl (5 to 7.2 mmol/l). Molarity and mass concentration Blood glucose is measured in terms of molarity, measured in mmol/L or millimoles per litre. In the United States, and to a lesser extent elsewhere, mass concentr Continue reading >>
Blood Sugar Levels & Ranges (low, Normal & High)
Normal sugar ranges or levels, mean the normal range of concentrations blood glucose levels (sugar) that occur in the blood measured by a test. Values that are below or above the range of values considered "normal" are abnormal. either too high or two low ( hypoglycemia and hypercyglycemia). Diabetes is defined as a disease in which the body has an impaired ability to either produce or respond to the hormone insulin . People with type 1 diabetes have a pancreas that does not make insulin. People with type 2 diabetes have cells in the body that are resistant to insulin or have a pancreas that slows or stops producing adequate insulin levels (blood glucose). Both types of diabetes can result in abnormal glucose levels. Normal blood levels may range slightly depending on what blood tests are used, and your doctor may have, but the variances are small. In addition, what are normal ranges for nondiabetics are not the same for diabetics; it is generally accepted that target blood sugar measurements for people with diabetes will be slightly higher than those without diabetes. A person who is does not have a normal glucose range of 72-99mg/dL while fasting and up to 140mg/dL about 2 hours after eating. People with diabetes who have well-controlled glucose levels with medications have a different target glucose range. These people may have a fasting range of about 100 mg/dL or less and 180mg/dL about 2 hours after eating. If a persons diabetes is not well controlled, the person may have much higher glucose ranges or hypoglycemia (for example, 200 -400 mg/d; however some people with diabetes have blood sugar levels that are much higher. Symptoms, Signs, Causes, of Levels of High Blood Sugar In the Blood High blood sugar or hyperglycemia is an abnormally high blood sugar (blood g 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 >>
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 >>
Is Your Fasting Blood Glucose Higher On Low Carb Or Keto? Five Things To Know
This past spring, after 18 months of great success on the keto diet, I tested my fasting blood sugar on my home glucose monitor for the first time in many months. The result shocked me. I had purchased the device, which also tests ketones, when I was diagnosed with pre-diabetes in the fall of 2015. As I embarked on low-carb keto eating, I tested my blood regularly. Soon my fasting blood sugar was once again in the healthy range. I was in optimal ketosis day after day. Not only that, I lost 10 lbs (5 kg) and felt fantastic — full of energy with no hunger or cravings. Before long I could predict the meter’s results based on what I was eating or doing. I put the meter away and got on with my happy, healthy keto life. When my doctor ordered some lab tests this spring, I brought the meter out again. While I had no health complaints, excellent blood pressure and stable weight, she wanted to see how my cholesterol, lipids, HbA1c, and fasting glucose were doing on my keto diet — and I was curious, too. To check the accuracy of my meter against the lab results, on the morning of the test I sat in my car outside the clinic at 7:30 am, and pricked my finger. I was expecting to see a lovely fasting blood glucose (FBG) of 4.7 or 4.8 mmol/l (85 mg/dl). It was 5.8! (103 mg/dl). What? I bailed on the tests and drove home — I didn’t want my doctor warning me I was pre-diabetic again when I had no explanation for that higher result. The next morning I tested again: 5.9! (104). Huh??? For the next two weeks I tested every morning. No matter what I did, my FBG would be in 5.7 to 6.0 (102 to 106 mg/dl), the pre-diabetic range again. One morning after a restless sleep it was even 6.2 mmol/l (113 mg/dl). But my ketones were still reading an optimal 1.5-2.5 mmol/l. I was still burnin Continue reading >>

Pre-diabetes: No Sweet News This
You need not wait to be a diabetic to treating diabetes. With campaigns on the run up to World Diabetes Day on November 14 advocating prevention of diabetes, focus is clearly on the pre-diabetes stage. The pre-diabetes stage is the ‘cat on the wall' stage as V.Ravindranath, consultant diabetologist, Tiruchi Diabetes Speciality Centre puts it, with blood glucose levels falling between the normal and diabetic range. Those in the pre-diabetic stage are potential diabetics as diabetes does not emerge overnight. Physicians and various specialists reiterate the significance of intervention at this crucial phase not only to prevent or delay onset of diabetes but to avoid other complications in the long run. Various studies have proved that cardiovascular complications including heart disease has already set in at the time of detection of diabetes in many patients opine cardiologists. Hence intervening at this stage means that complications are stalled. “Pre-diabetic stage precedes diabetes by five to ten years. While macro vascular complications like cardiac disease, stroke and peripheral vascular disease set in ten years before diagnosis of diabetes, micro vascular conditions like diabetic retinopathy (eye disease), diabetic nephropathy(kidney) and neuropathy (nerves) set in before five years,” says Dr.Ravindranath. When someone is diagnosed with diabetes, it is advisable to check for these complications immediately, he adds. Though family history and genetic predisposition plays an important role in developing type II diabetes, there are those who develop diabetic due to non-genetic factors like obesity, high stress levels, faulty diet and sedentary lifestyle. What worries doctors is the early onset of diabetes. Though age remains a risk factor, incidence of diabetes i Continue reading >>
