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.

Know Your Numbers: Why Blood Pressure, Blood Sugar And Cholesterol Matter | Miami Herald
Along with eating right and exercise, knowing your numbers is a crucial part of managing your heart health correctly. Below, Dr. Theodore Feldman, a cardiologist at West Kendall Baptist Hospital and the medical director of the Healthy Hub at West Kendall, takes us through the ABCs of cardiovascular health. BLOOD PRESSURE Why it’s important to keep track: High blood pressure, or hypertension, negatively impacts the heart in three major ways: It makes the heart work harder, it accelerates the build-up of plaque in the arteries, and it can create imbalances between the supply and demand of oxygen to and from the heart. A leading cause of heart failure, kidney disease and stroke, hypertension is also typically completely asymptomatic, making it a “silent killer,” according to Feldman. Consistently low blood pressure can also indicate a problem, but only if accompanied by symptoms like fatigue, nausea, dizziness or fainting and blurred vision. Never miss a local story.

The top number, also the higher number, represents systolic blood pressure – the pressure when the heart is contracted. The bottom number represents diastolic blood pressure – the pressure in the arteries when the heart is relaxed. Systolic blood pressure usually fluctuates the most. Ranges: Healthy systolic readings are below 120 mm Hg; healthy diastolic readings are below 80 mm Hg. Pre-hypertensive systolic readings are 120 – 139 mm Hg; pre-hypertensive diastolic readings are 80 – 89 mm Hg. Systolic readings of 140 – 159 mm Hg and diastolic readings between 90 – 99 mm Hg represent Stage 1 h Continue reading >>
Blood Sugar Guidelines
Absolute numbers vary between pets, and with meter calibrations. The numbers below are as shown on a typical home glucometer while hometesting blood glucose, not necessarily the more accurate numbers a vet would see (though many vets use meters similar to those used in hometesting). For general guidelines only, the levels to watch are approximately: mmol/L mg/dL(US) <2.2 <40 Readings below this level are usually considered hypoglycemic when giving insulin, even if you see no symptoms of it. Treat immediately 2.7-7.5 50-130 Non-diabetic range (usually unsafe to aim for when on insulin, unless your control is very good). These numbers, when not giving insulin, are very good news. 3.2-4.4 57-79 This is an average non-diabetic cat's level, but leaves little margin of safety for a diabetic on insulin. Don't aim for this range, but don't panic if you see it, either. If the number is not falling, it's healthy. 5 90 A commonly cited minimum safe value for the lowest target blood sugar of the day when insulin-controlled. 7.8 140 According to the American Association of Clinical Endocrinologists (AACE), threshold above which organ and pancreatic dysfunction may begin in hospitalized humans and the maximum target for post-meal blood glucose in humans. 5.5-10 100-180 Commonly used target range for diabetics, for as much of the time as possible. <10-15 <180-270 "Renal threshold" (varies between individuals, see below), when excess glucose from the kidneys spills into the urine and roughly when the pet begins to show diabetic symptoms. See Hyperglycemia for long-term effects of high blood glucose. 14 250 Approximate maximum safe value for the highest blood sugar of the day, in dogs, who are more sensitive to high blood sugar. Dogs can go blind at this level. Cats 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 >>
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.

A High Sugar Level After A Meal
It's normal for your blood sugar level to rise after you eat, especially if you eat a meal high in refined carbohydrates. But if your blood sugar rises more than most people's, you might have diabetes or pre-diabetes, a condition that indicates a strong risk for developing diabetes in the future. If you already have diabetes, you doctor will recommend keeping your blood sugar within a prescribed range. A glucose tolerance test, done one to three hours after you eat a high-carbohydrate meal, can check your blood sugar levels. Why Does Your Blood Sugar Rise? When you eat carbohydrates, your body breaks down the sugars they contain into glucose. Your body can't absorb most sugars without breaking them down first. Simple sugars such as refined sugar break down very quickly; you absorb them rapidly into your bloodstream, which raises your blood sugar. In healthy people, the levels don't rise very high and they drop back to normal quickly. If you have diabetes, your levels after a meal will rise higher and stay high longer than levels in other people. This occurs because your pancreas either don't release enough insulin, the hormone that helps cells absorb glucose, or because the cells don't respond properly to insulin release. Normal Levels If your doctor suspects that you have abnormal glucose levels, he might suggest doing a glucose tolerance test. You are given around 75 grams of carbohydrate after fasting for 12 hours. At one- to three-hour intervals, your doctor draws blood and analyzes your glucose levels. A normal fasting glucose is 60 to 100 milligrams per deciliter; your levels should rise no higher than 200 mg/dl one hour after eating and no more than 140 mg/dl two hours after finishing the snack. Most healthy people without diabetes have two-hour readings below 12 Continue reading >>

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.

Goals For Blood Glucose Control
Discuss blood glucose (sugar) targets with your healthcare team when creating your diabetes management plan. People who have diabetes should be testing their blood glucose regularly at home. Regular blood glucose testing helps you determine how well your diabetes management program of meal planning, exercising and medication (if necessary) is doing to keep your blood glucose as close to normal as possible. The results of the nationwide Diabetes Control and Complications Trial (DCCT) show that the closer you keep your blood glucose to normal, the more likely you are to prevent diabetes complications such as eye disease, nerve damage, and other problems. For some people, other medical conditions, age, or other issues may cause your physician to establish somewhat higher blood glucose targets for you. The following chart outlines the usual blood glucose ranges for a person who does and does not have diabetes. Use this as a guide to work with your physician and your healthcare team to determine what your target goals should be, and to develop a program of regular blood glucose monitoring to manage your condition. Time of Check Goal plasma blood glucose ranges for people without diabetes Goal plasma blood glucose ranges for people with diabetes Before breakfast (fasting) < 100 70 - 130 Before lunch, supper and snack < 110 70 - 130 Two hours after meals < 140 < 180 Bedtime < 120 90- 150 A1C (also called glycosylated hemoglobin A1c, HbA1c or glycohemoglobin A1c) < 6% < 7% < = less than > = greater than > = greater than or equal to < = less than or equal to Information obtained from Joslin Diabetes Center's Guidelines for Pharmacological Management of Type 2 Diabetes.

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.

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 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.

Lows & Highs: Blood Sugar Levels
Keeping blood glucose (sugar) levels in a healthy range can be challenging. Knowing and understanding the symptoms of high and low blood sugar is very important for people living with diabetes, as well as their friends and family members. What is low blood glucose (sugar)? When the amount of blood glucose (sugar in your blood) has dropped below your target range (less than four mmol/L), it is called low blood glucose (sugar) or hypoglycemia. What are the signs of a low blood glucose (sugar) level? You may feel: Shaky, light-headed, nauseated Nervous, irritable, anxious Confused, unable to concentrate Hungry Your heart rate is faster Sweaty, headachy Weak, drowsy A numbness or tingling in your tongue or lips Very low blood glucose can make you: Confused and disoriented Lose consciousness Have a seizure Make sure you always wear your MedicAlert® identification, and talk to your doctor or diabetes educator about prevention and emergency treatment for severe low blood glucose (sugar). What causes a low blood glucose (sugar) level (hypoglycemia)? Low blood glucose (sugar) may be caused by: More physical activity than usual Not eating on time Eating less than you should have Taking too much medication The effects of drinking alcohol How do I treat low blood glucose (sugar)? If you are experiencing the signs of a low blood glucose (sugar) level, check your blood glucose (sugar) immediately. If you don’t have your meter with you, treat the symptoms anyway. It is better to be safe. Step one: Low blood glucose (sugar) can happen quickly, so it is important to treat it right away. If your blood glucose (sugar) drops very low, you may need help from another person. Eat or drink a fast-acting carbohydrate (15 grams): 15 grams of glucose in the form of glucose tablets (preferred c Continue reading >>

A Guide To Blood Sugar Levels
(Q) My doctor says that my sugar level was 8.0. Can you tell me if this is very high or just above normal? (A) Usually blood sugar levels are tested in the 'fasting' state – when you have not had anything to eat or drink for eight hours. The normal range for fasting blood sugar is anything from 3.0 to 5.5 mmol/L. If you have not fasted, the normal range for random blood sugar is between 3.0 and 7.8 mmol/L. The body can usually keep the blood sugar within this range despite variations in food intake and energy expenditure, but if the blood test is done very soon after eating it is possible it may be slightly above. Other conditions which may temporarily cause increased blood sugar readings include acute infection, trauma and physical or psychological stress. In such cases the raised blood sugar may not be indicative of diabetes and the test should be repeated once the condition of circumstances have stabilised or resolved. If your blood test was done immediately after eating a large amount of carbohydrates or if you had a concurrent health condition or circumstances such as those described above, this might explain the result being mildly above the range for random glucose. But if your result of 8.0 was after fasting for eight hours this is very concerning as it could well indicate a diagnosis of diabetes. If you did not fast for your last test, your doctor may advise you to repeat the test and fast this time and hopefully it will be in range (below 5.5 mmol/L). If your level of 8.0 was already fasting your doctor may advise repeating the test (a fasting blood sugar that is repeatedly over 7.0 indicates a diagnosis of diabetes) and possibly doing a further test known as a 'glucose tolerance test' (GTT). With the GTT you have a baseline fasting blood sugar level done an Continue reading >>
