Fasting blood glucose is a measure of the quantity of glucose present in an individual’s blood stream after abstaining from eating for at least eight hours.1 This test is used to screen for diabetes. The chart below provides fasting blood sugar numbers and descriptions as provided by the American Diabetes Association. For a comprehensive overview of Diabetes, see our Diabetes section under medical health issues. HDL Cholesterol and LDL Cholesterol The two basic types of cholesterol with which we are concerned with are LDL and HDL cholesterol.

Blood sugar or blood glucose refers to sugar that is transported through the bloodstream to supply energy to all the cells in our bodies. Sugar is a simple, crystalline, edible carbohydrate and comes in a variety of forms, all of them sweet. The human digestive system breaks down the carbohydrates from food into various sugar molecules - one of them is glucose, the body's principal source of energy. After we eat, blood sugar concentrations rise, the pancreas releases insulin automatically so that the glucose enters cells, as more and more cells receive glucose, blood sugar levels come down to normal again. If you have not eaten for a while and blood glucose concentrations keep dropping, the pancreas releases another hormone called glucagon.
Blood sugar or blood glucose are shortened terms for blood sugar concentration or blood glucose level. Long-term hyperglycemia may eventually lead to complications that affect the small blood vessels that supply the nerves, kidneys, retina and other organs. Slight blood glucose increase raises heart disease risk - researchers from Copenhagen University Hospital found that after checking data on 80,000 people, that even slightly elevated blood sugar concentrations can eventually lead to a 69% higher risk of ischemic cardiovascular disease. One third of community hospital patients have high blood sugar concentrations - experts from Emory University in Atlanta, Georgia, USA, found that from 32% to 38% of all patients in community hospitals suffer from hyperglycemia.
The human brain is a voracious consumer of glucose, it neither manufactures nor stores glucose - the brain depends completely on glucose coming from the bloodstream.
Too much alcohol - if you drink too much without having eaten, your liver may not release glycogen.
Some illnesses - especially critical ones, such as severe hepatitis and disorders of the kidney.
Excessive insulin production - certain illnesses may have insulinoma as one of its symptoms, for example, some tumors produce insulin-like chemicals; in some cases the tumor itself consumes so much glucose that there is not enough for the rest of the body. Disorders of the endocrine system - some pituitary and adrenal gland disorders may lead to abnormally low production and release of some hormones which play a key role in the production of glucose.
Typically, the diabetes patient tests blood glucose levels with a glucose meter - which comes with lancets (tiny needles), a logbook and test strips.
Keep a log of each glucose reading; this helps the doctors find the best treatment plan for you. Regulatory authorities need to keep a close check on the accuracy of medical devices used for testing blood glucose levels.
In general, patients with diabetes type 2 test their blood sugar concentrations at least once each day.

Learn all about diabetes, a lifelong metabolism disorder that causes high blood sugar levels. Learn all about type 1 and type 2 diabetes and the differences between the two conditions in our article about the diabetes mellitus metabolism disorder. THE MEDICAL PROFESSION WOULD have you believe that diabetes is not reversible and only controlling your blood sugar with drugs or insulin will protect you from organ damage and death.
The diabetes epidemic is accelerating along with the obesity epidemic, and what you are not hearing about is another way to treat it. Type 2 diabetes, or what was once called adult onset diabetes, is increasing worldwide and now affects nearly 100 million people — and over 20 million Americans. We are seeing increasing rates of Type 2 diabetes, especially in children, which has increased over 1,000 percent in the last decade and was unknown before this generation.


In a report in The New England Journal of Medicine, Walter Willett, MD, PhD, and his colleagues from the Harvard School of Public Health demonstrated that 91 percent of all Type 2 diabetes cases could be prevented through improvements lifestyle and diet.
Here, I want to review in detail this new way of thinking about diabetes and outline the tests I recommend to identify problems with blood sugar. When your diet is full of empty calories, an abundance of quickly absorbed sugars and carbohydrates (bread, pasta, rice, potatoes, etc.), the body slowly becomes resistant to the effects of insulin and needs more to do the same job of keeping your blood sugar even.
Insulin resistance and the metabolic syndrome associated with it is often accompanied by increasing central obesity, fatigue after meals, sugar cravings, high triglycerides, low HDL, high blood pressure, problems with blood clotting, as well as increased inflammation.
These clues can often be picked up decades before anyone ever gets diabetes — and may help you prevent diabetes entirely. If you have a family history of obesity (especially around the belly), diabetes, early heart disease, or even dementia you are even more prone to this problem. Most people know about the common complications of diabetes such as heart attacks, strokes, amputations, blindness, kidney failure, and nerve damage. Diabetes and pre-diabetes ARE reversible by aggressively changing lifestyle, nutritional support, and occasionally medications. In fact many people with pre-diabetes never get diabetes, but they are at severe risk just the same. We were highly adapted to a nutrient-dense, low-sugar, high-fiber diet rich in omega-3 fats. Now, in just one generation, they are nearly all obese and 80 percent have diabetes by the time they are 30 years old!
New science shows that it’s possible, through an aggressive approach of lifestyle, nutritional support, and occasionally medications. It is important to diagnose Type 2 diabetes early, but it is often not diagnosed until very late. In fact, all doctors should aggressively diagnose pre-diabetes decades before diabetes occurs, and before any damage is done to your body. Unfortunately, there is a continuum of risk from slightly abnormal insulin and blood sugar to full blown diabetes.
In a recent study, anyone with a fasting blood sugar of over 87 was at increased risk of diabetes. Most doctors are not concerned until the blood sugar is over 110 — or worse, over 126, which is diabetes.
Insulin Glucose Challenge Test – This should be done with a 2-hour glucose challenge, 75 grams measuring fasting, 1- and 2-hour blood sugar AND insulin. Hemoglobin A1C Test – This is an important measure of glycated hemoglobin, which can be an early indicator of sugar problems.
NMR Lipid Profile – This test is slightly different from the one above as it identifies the size of your cholesterol particles.
High Sensitivity C-Reactive Protein Test – This is a measure of inflammation, one of the classic conditions that is both the cause and result of insulin resistance and diabetes. Fibrinogen Test – This measures your risk of clotting, which can cause heart attacks and strokes.

Wireless Blood Glucose Monitor System is intended to be used for the quantitative measurement of glucose (sugar) in fresh capillary whole blood samples drawn from the fingertips, palm, forearm, upper arm, calf and thigh. Your use of this website constitutes acknowledgement and acceptance of our Terms & Conditions. Glucose, one type of sugar, is the one in the bloodstream that feeds cells and matters to us. The glucose goes straight from the digestive system into the bloodstream after we have consumed and digested food. Glucagon triggers the breakdown of glycogen into glucose, thus pushing blood glucose levels back up to normal. They are at their lowest point before our first meal in the day, which for most people (not shift workers) is breakfast.
People with poorly controlled diabetes, Cushing's syndrome and some other illnesses frequently suffer from hyperglycemia. There is a risk of becoming blind, developing renal disease, erectile dysfunction, foot ulcers and other illnesses and conditions. They added that people should have their blood glucose levels checked as soon as they are hospitalized, as this would most likely reduce the numbers of hospital complications in surgery and general medicine patients.


Most people with hypoglycemia can tell by the symptoms associated with the condition (a significant minority cannot).
If the kidneys and liver do not work properly, it is harder for the body to break down and excrete medications.
Many have to check several times each day so that they can plan for activities, meals, and when to take their medications. There are several meter manufacturers which make a wide range of different devices - however, they all do the same, measure the patients' blood-glucose levels. In 2009, the US FDA (Food and Drug Administration informed that blood glucose meters that used GDH-PQQ test strips could be giving false readings - and that that some patients might have been using too much insulin as a result. Those needing to take insulin, which includes everyone with diabetes type 1 and some with type 2, have to test their blood several times a day.
But medication and insulin can actually increase your risk of getting a heart attack or dying. Insulin resistance, when the body becomes resistant to the effects of insulin, is primarily what causes diabetes. The high insulin leads to an appetite that is out of control, and increasing weight gain around the belly. Some may even know that it increases your risk of dementia and cancers and can cause impotence. Therefore, I recommend early testing with anyone who has a family history of Type 2 diabetes, central abdominal weight gain or abnormal cholesterol. Your blood sugar should be less than 80 fasting and never rise above 110 or 120 after one to two hours.
It measures sugars and proteins combining into glycated proteins called AGEs (advanced glycation end products), like the crust on bread, or the crispy top on creme brule. An HDL or good cholesterol level under 60 and triglycerides over 100 should make you suspicious of insulin resistance. With insulin resistance or Type 2 diabetes, you develop small LDL and HDL cholesterol particles. I have seen this hundreds of times in my patients and there is no reason you can’t achieve the same thing if you apply these principles. The BG5 Blood Glucose Monitoring System is intended to be used by a single patient and should not be used for testing multiple patients.
The human body regulates blood glucose levels so that they are neither too high nor too low - maintaining a condition of stability or equilibrium in the blood's internal environment (homeostasis) is necessary for our bodies to function. It normally occurs when there is not enough insulin in the body, or the body is not responding to the insulin properly. It is possible to estimate a person's 10 year risk of retinopathy by measuring their blood glucose levels.
Your insulin should be less than 5 fasting and should never rise above 30 after one to two hours. These create inflammation and oxidative stress throughout the body, and promote heart disease and dementia and accelerating aging. They are much more dangerous than larger particles and lead to increased risk of atherosclerosis or heart disease. In fact, anyone with a high C-reactive protein has a 1,700 percent increased risk of getting diabetes.
This is entirely due to sugar and carbohydrates in our diet that cause fatty liver, liver damage, and even cirrhosis.
The BG5 Blood Glucose Monitoring System is intended for self-testing outside the body (in vitro diagnostic use) by people with diabetes at home as an aid to monitor the effectiveness of diabetes control.
I recommend this test for everyone over 50, and for anyone with any risk of insulin resistance, even children. The Wireless Blood Glucose Monitor System should not be used for the diagnosis of or screening for diabetes, nor for neonatal use.
Alternative site testing should be done only during steady - state times (when glucose is not changing rapidly).
