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).

Marijuana Use Tied To Higher Blood Sugar In Middle Age
(Reuters Health) - Marijuana use may increase the risk of high blood sugar during middle age, suggests a new study that contradicts earlier reports. What little research exists on the topic has found that pot smokers tend to be at lower than average risk of diabetes, so the finding that they may have elevated, so-called pre-diabetic blood sugar levels comes as a surprise, the study authors say. Prediabetes is “a risk factor for future cardiovascular disease, but if recognized, it is also an intervention point and opportunity to prevent the progression to diabetes and mitigate risk for future cardiovascular disease,” said lead author Mike Bancks, of the University of Minnesota School of Public Health in Minneapolis. Past studies have found that while marijuana users tend to eat more than non-users, they ended up with characteristics that suggest lower diabetes risk, like healthier weight and smaller waists, the researchers write in Diabetologia. One such study found that people who used marijuana were 30 percent less likely to develop type 2 diabetes. But those earlier studies may have been unreliable, the current researchers suggest. For example, results may be skewed if people change their marijuana use over time, based on their health. The new research involved two separate analyses. Like past research, there was no increased risk of full-blown diabetes among marijuana users in either analysis - but there was a higher risk for elevated blood sugar levels. One analysis involved 3,034 participants in a study that tracked their health and marijuana use since the 1980s, when they were 18 to 30 years old. Twenty-five years later, in 2010 and 2011, 45 percent of the now middle-aged participants had elevated blood sugar levels. Those who were current marijuana users were Continue reading >>
Healthy Aging With Diabetes
“I can tell you one thing — growing old ain’t for wimps!” —gray-haired gentleman at Sterling Center YMCA in Beverly, Massachusetts It used to be said that having diabetes aged people an additional 20 years. Today, thanks to better tools for managing diabetes and preventing and treating its complications, people with diabetes have the opportunity to live longer than ever before. However, managing diabetes in the golden years presents a variety of challenges, ranging from increased insulin resistance to being on multiple drugs. Here is what you should know about the effects of diabetes on aging and vice versa, and what you can do to stay healthy and full of vitality well into old age. What happens during aging As you age, you may be most aware of your new gray hairs and wrinkles, but aging causes changes throughout the entire body. A person’s basal metabolic rate — the amount of energy the body expends at rest — declines with age. By some estimates, a person’s basal metabolism drops by 2% per decade starting at age 20. Some researchers believe that this decline is due almost solely to the loss of muscle mass that comes with age. The body’s ability to process oxygen — its aerobic capacity — also declines with age. By some estimates, a person’s aerobic capacity by age 65 is typically only 60% to 70% of what it was when he was younger (although the decline appears to be less in older people who exercise regularly). This decline may be due to several factors, including poor lung function, heart function, and blood circulation. With advancing years, the body gradually becomes less adept at taking up and using glucose from the bloodstream — a condition known as glucose intolerance, which sets the stage for Type 2 diabetes. One contributing factor to Continue reading >>
Glucose: The Silent Killer
The deadly effects of even slightly elevated glucose are fatally misunderstood. One reason for this calamity is physicians who continue to rely on obsolete blood glucose ranges. These doctors fail to recognize that any excess glucose creates lethal metabolic pathologies that are underlying factors behind multiple age-related diseases. People today thus suffer and die from diabetic-like complications without knowing their blood sugar (glucose) levels are too high! Life Extension® long ago argued that most aging people have elevated blood glucose. Our controversial position has been vindicated as mainstream medicine consistently lowers the upper-level threshold of acceptable (safe) fasting blood glucose. As new evidence accumulates, it has become abundantly clear that maturing individuals need to take aggressive actions to ensure their fasting and after-meal glucose levels are kept in safe ranges. Glucose Is Like Gasoline Our body’s primary source of energy is glucose. All of our cells use it, and when there is not enough glucose available, our body shuts down in a similar way that a car engine stops when the gasoline tank is empty. When glucose is properly utilized, our cells produce energy efficiently. As cellular sensitivity to insulin diminishes, excess glucose accumulates in our bloodstream. Like spilled gasoline, excess blood glucose creates a highly combustible environment from which oxidative and inflammatory fires chronically erupt. Excess glucose not used for energy production converts to triglycerides that are either stored as unwanted body fat or accumulate in the blood where they contribute to the formation of atherosclerotic plaque.1-6 If you were filling your automobile with gasoline and the tank reached full, you would not keep pumping in more gas.

Is It Normal For Blood Pressure And Blood Sugar To Rise As We Age?
Q. My bloood pressure and blood sugar have been rising slowly over the past 10 years but are still in a healthy range. Should I worry? A. If you are otherwise healthy, small, steady increases in blood pressure and blood glucose that are still within the normal range are probably nothing to worry about. If your health habits need a tuneup, rising numbers are a reminder to take action before they become a threat. Lifestyle changes can often help control rising blood pressure. So quit smoking, cut back on sodium, lose excess weight, exercise regularly, and drink moderately, if at all. These same healthy habits are also key to keeping blood sugar levels in check. It’s also worth noting that the new expert thinking is that slightly higher blood pressure is OK for adults older than 60, says Consumer Reports chief medical adviser Marvin M. Lipman, M.D. And because blood sugar processing slows with age, Lipman says, adults older than 70 may not need the strict blood sugar control that’s important for younger people to prevent future complications.

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.

Does Age Make Diabetes Harder To Control?
It seems that the older I get, the harder it is to control my diabetes and keep my A1C down. Right now, it is an unhealthy 9 percent. When I was younger, it used to be in the 7 range. Is it my age that is making my diabetes so hard to manage? 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.

Children blood sugar levels Blood sugar levels chart Checking for BS: How to check blood sugar? Treatment: How to lower blood sugar level? Can diabetes be cured? 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 >>
Aging Is Associated With Increased Hba1c Levels, Independently Of Glucose Levels And Insulin Resistance, And Also With Decreased Hba1c Diagnostic Specificity.
Abstract AIM: To determine whether using HbA1c for screening and management could be confounded by age differences, whether age effects can be explained by unrecognized diabetes and prediabetes, insulin resistance or postprandial hyperglycaemia, and whether the effects of aging have an impact on diagnostic accuracy. METHODS: We conducted a cross-sectional analysis in adults without known diabetes in the Screening for Impaired Glucose Tolerance (SIGT) study 2005-2008 (n=1573) and the National Health and Nutrition Examination Survey (NHANES) 2005-2006 (n=1184). RESULTS: Both glucose intolerance and HbA(1c) levels increased with age. In univariate analyses including all subjects, HbA(1c) levels increased by 0.93 mmol/mol (0.085%) per 10 years of age in the SIGT study and by 1.03 mmol/mol (0.094%) per 10 years in the NHANES; in both datasets, the HbA(1c) increase was 0.87 mmol/mol (0.08%) per 10 years in subjects without diabetes, and 0.76 mmol/mol (0.07%) per 10 years in subjects with normal glucose tolerance, all P<0.001. In multivariate analyses of subjects with normal glucose tolerance, the relationship between age and HbA(1c) remained significant (P<0.001) after adjustment for covariates including race, BMI, waist circumference, sagittal abdominal diameter, triglyceride/HDL ratio, and fasting and 2-h plasma glucose and other glucose levels, as assessed by an oral glucose tolerance test. In both datasets, the HbA(1c) of an 80-year-old individual with normal glucose tolerance would be 3.82 mmol/mol (0.35%) greater than that of a 30-year-old with normal glucose tolerance, a difference that is clinically significant. Moreover, the specificity of HbA(1c) -based diagnostic criteria for prediabetes decreased substantially with increasing age (P<0.0001). CONCLUSIONS: In two la Continue reading >>

Effects Of Age On Plasma Glucose Levels In Non-diabetic Hong Kong Chinese
Go to: Subjects and methods In this survey, performed in the period between April 1996 and August 1997, we recruited 17 242 adult subjects from the community of Hong Kong. The methodology has been reported before (6). Volunteer participants came to the United Christian Nethersole Community Health Service (UCHCNS) Centers for health assessment. UCNCHS is a self-funded, non-profit organization with the objective of health promotion through primary health care and education. Participants came from different districts all over Hong Kong. All of them gave verbal informed consent before the examination was performed. Participants were interviewed and examined by a nursing officer and a clinician. Demographic data, and past and present medical history were collected. Demographic data, including height and weight (measured to the nearest 0.1 kg) and blood pressure, were obtained following the standard protocol, with the subject in light clothing without shoes. Blood pressure was measured on the right arm with a standard mercury sphygmomanometer. The Korotkoff sound V was taken as the diastolic blood pressure. Blood specimens were taken from all participants. The timing of blood taking varied depending on the availability of the patient. According to the time of blood sampling, there were three types of plasma glucose samples. Fasting plasma glucose was measured after overnight fasting for at least 10 hours, 2-hour post-prandial plasma glucose glucose was measured 2 hours after a meal of usual quantity, and random plasma glucose was collected in the time periods other than fasting or 2-hour post-prandial. Plasma glucose was measured by a hexokinase method (Hitachi 911, analyzer Boehringer Mannheim, Mannheim, Germany). The intra-assay coefficient of variation (CV) of glucose was Continue reading >>
Diabetes: What You Need To Know As You Age
Overview Diabetes is a problem that has many consequences: If you have the disease, your body can no longer keep its blood sugar at a healthy level. But over time, the effects of diabetes can become much more complicated. The disease can lead to serious, even life-threatening problems from your head to your toes. Too much blood sugar (also called glucose) can damage the blood vessels and nerves that run throughout your body. This can set the stage for many other medical conditions: stroke heart disease kidney disease vision problems and blindness damage to the feet or legs However, there is good news for the 26 million Americans with diabetes—and those at risk. Experts are learning more all the time about lifestyle steps for diabetes control and prevention. New medications and devices can also help you keep control over your blood sugar and prevent complications, says Johns Hopkins expert Rita Kalyani, M.D. Definitions A1C Test: A blood test used to diagnose and monitor diabetes. By measuring how much glucose (also called blood sugar) is attached to the oxygen-carrying protein in your red blood cells, this test gives you and your health-care provider a picture of your average blood glucose levels over three months. A normal result is below 5.7 percent. If you have type 2 diabetes, you should have this test done twice a year to check if your blood glucose is under control. Blood glucose: Also referred to as blood sugar, the primary energy source for the cells in your body. Blood glucose levels rise after meals and fall the longer you’ve gone without eating. Your blood glucose level is a measure of how much glucose you have in your bloodstream. A normal fasting blood glucose level is between 70 and 100 mg/dl (milligrams per deciliter of blood). Insulin (in-suh-lin): A Continue reading >>
What Is Prediabetes? Prediabetes is a “pre-diagnosis” of diabetes—you can think of it as a warning sign. It’s when your blood glucose level (blood sugar level) is higher than normal, but it’s not high enough to be considered diabetes. Prediabetes is an indication that you could develop type 2 diabetes if you don’t make some lifestyle changes. But here's the good news: . Eating healthy food, losing weight and staying at a healthy weight, and being physically active can help you bring your blood glucose level back into the normal range. Diabetes develops very gradually, so when you’re in the prediabetes stage—when your blood glucose level is higher than it should be—you may not have any symptoms at all. You may, however, notice that: you’re hungrier than normal you’re losing weight, despite eating more you’re thirstier than normal you have to go to the bathroom more frequently you’re more tired than usual All of those are typical symptoms associated with diabetes, so if you’re in the early stages of diabetes, you may notice them. Prediabetes develops when your body begins to have trouble using the hormone insulin. Insulin is necessary to transport glucose—what your body uses for energy—into the cells via the bloodstream. In pre-diabetes, your body either doesn’t make enough insulin or it doesn’t use it well (that’s called insulin resistance). If you don’t have enough insulin or if you’re insulin resistant, you can build up too much glucose in your blood, leading to a higher-than-normal blood glucose level and perhaps prediabetes. Researchers aren’t sure what exactly causes the insulin process to go awry in some people. There are several risk factors, though, that make it more likely that you’ll develop pre-diabetes. These are Continue reading >>
Common Questions About Blood Sugar
How often should I test my blood sugar? This is a very common question, and the answer isn't the same for everyone. In general, you should test as often as you need to get helpful information. There's no point in testing if the information you get doesn't help you manage your diabetes. If you've been told to test at certain times, but you don't know why or what to do with the test results, then testing won't seem very meaningful. Here are some general guidelines for deciding how often to test: If you can only test once a day, then do it before breakfast. Keep a written record so that you can see the pattern of the numbers. If you control your blood sugar by diet and exercise only, this once-a-day test might be enough. If you take medicine (diabetes pills or insulin), you will probably want to know how well that medicine is working. The general rule is to test before meals and keep a record. If you want to know how your meals affect your blood sugar, testing about 2 hours after eating can be helpful. Test whenever you feel your blood sugar is either too high or too low. Testing will give you important information about what you need to do to raise or lower your blood sugar. If you take more than 2 insulin shots a day or use an insulin pump, you should test 4 to 6 times a day. You should test more often if you're having unusually high or low readings, if you're sick, under more stress than usual, or are pregnant. If you change your schedule or travel, you should also test your blood sugar more often than usual. Talk to a member of your health care team about how often to test based on your personal care plan. What should my test numbers be? There isn't one blood sugar target that's right for everyone with diabetes. It's important to work with your health care team to set 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 >>

The Correct Interpretation Of Blood Glucose
Go to:Table of Contents of all my Rejuvenation Pages The Glucose Theory of Aging (The Gospel only According to Saint Ellis...) NOTE: See another opinion below... Chad: "I feel obligated, based on my knowledge of this subject, to attempt to prevent people (particularly diabetics) from reading the advice on your website and going out there and attempting it... and killing themselves." "EAT IN SUCH A WAY THAT YOU KEEP YOUR FASTING BLOOD GLUCOSE LEVEL BETWEEN 70 AND 85 mg/dl, AND (AT MOST) 70 - 100 mg/dl. AFTER EATING. EVERY MOMENT THAT YOUR GLUCOSE LEVEL IS HIGHER THAN 85 mg/dl YOU ARE AGING A LITTLE BIT FASTER THAN THE MINIMUM. THIS IS TRUE EVEN IF IT IS "NORMAL". THE HIGHER ABOVE 85 YOU GO, THE LONGER IT WILL TAKE FOR BLOOD GLUCOSE TO COME DOWN TO 85 AGAIN, AND THE FASTER AND MORE SERIOUSLY WILL YOU AGE. - Ellis Toussier, June 2001 Aging does not occur as a function of the passing of time: hours, or days... Aging occurs as a function of events that occur during the passing of time, the passing of a unit which I will call "high glucose level seconds" or hours, or days... - Ellis Toussier, May, 2006 The following table is my interpretation of the meaning of the various glucose levels. The figure on the right is my educated guess of the relative damage in seconds that you might be suffering at various glucose levels... it is not just "more damage" the higher up you go, but "more damage, squared" because a red hot iron will then cool off to a very hot iron, and then to a hot iron... you suffer damage going up, then you also suffer damage going down. Perhaps the figures are mistaken, but the idea that damage is much worse the higher the glucose goes up is correct.
