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 >>
Drugs That Can Raise Bg
By the dLife Editors Some medicines that are used for treating other medical conditions can cause elevated blood sugar in people with diabetes. You may need to monitor your blood glucose more closely if you take one of the medicines listed below. It’s important to note that just because a medicine has the possibility of raising blood sugar, it does not mean the medicine is unsafe for a person with diabetes. For instance, many people with type 2 diabetes need to take a diuretic and a statin to lower blood pressure and cholesterol. In these and many other cases, the pros will almost always outweigh the cons. Don’t ever take matters of medication into your own hands. Discuss any concerns you have with your healthcare provider. Certain Antibiotics Of all the different antibiotics, the ones known as quinolones are the only ones that may affect blood glucose. They are prescribed for certain types of infection. Levofloxacin (Levaquin) Ofloxacin (Floxin) Moxifloxacin (Avelox) Ciprofloxacin (Cipro, Cipro XR, Proquin XR) Gemifloxacin (Factive) Second Generation Antipsychotics These medicines are used for a variety of mental health conditions. There is a strong association between these medicines and elevated blood sugar, and frequent monitoring is recommended. Clozapine (Clozaril) Olanzapine (Zyprexa) Paliperidone (Invega) Quietiapine (Seroquel, Seroquel XR) Risperidone (Risperdal) Aripiprazole (Abilify) Ziprasidone (Geodon) Iloperidone (Fanapt) Lurasidone (Latuda) Pemavanserin (Nuplazid) Asenapine (Saphris) Beta Blockers Beta blockers are used to treat high blood pressure and certain heart conditions. Not all available beta blockers have been shown to cause high blood sugar. Atenolol Metoprolol Propranolol Corticosteroids Corticosteroids are used to treat conditions where th Continue reading >>
Controlling Blood Sugar Levels
Glucose is a sugar needed by cells for respiration. It is important that the concentration of glucose in the blood is maintained at a constant level. Insulin, a hormone secreted by the pancreas, controls blood sugar levels in the body. It travels from the pancreas to the liver in the bloodstream. As with other responses controlled by hormones, the response is slower but longer lasting than if it had been controlled by the nervous system. Blood sugar levels- Higher tier What happens when glucose levels in the blood become too high or too low glucose level effect on pancreas effect on liver effect on glucose level too high insulin secreted into the blood liver converts glucose into glycogen goes down too low insulin not secreted into the blood liver does not convert glucose into glycogen goes up Use the animation to make sure you understand how this works.

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.

Diabetes-related High And Low Blood Sugar Levels
Topic Overview Diabetes-related blood sugar levels When you have diabetes, you may have high blood sugar levels (hyperglycemia) or low blood sugar levels (hypoglycemia) from time to time. A cold, the flu, or other sudden illness can cause high blood sugar levels. You will learn to recognize the symptoms and distinguish between high and low blood sugar levels. Insulin and some types of diabetes medicines can cause low blood sugar levels. Learn how to recognize and manage high and low blood sugar levels to help you avoid levels that can lead to medical emergencies, such as diabetic ketoacidosis or dehydration from high blood sugar levels or loss of consciousness from severe low blood sugar levels. Most high or low blood sugar problems can be managed at home by following your doctor's instructions. You can help avoid blood sugar problems by following your doctor's instructions on the use of insulin or diabetes medicines, diet, and exercise. Home blood sugar testing will help you determine whether your blood sugar is within your target range. If you have had very low blood sugar, you may be tempted to let your sugar level run high so that you do not have another low blood sugar problem. But it is most important that you keep your blood sugar in your target range. You can do this by following your treatment plan and checking your blood sugar regularly. Sometimes a pregnant woman can get diabetes during her pregnancy. This is called gestational diabetes. Blood sugar levels are checked regularly during the pregnancy to keep levels within a target range. Children who have diabetes need their parents' help to keep their blood sugar levels in a target range and to exercise safely. Be sure that children learn the symptoms of both high and low blood sugar so they can tell others wh Continue reading >>

Google's Prototype "smart Contact Lens": Measuring Blood Glucose Levels For People With Diabetes
Earlier this year, Google unveiled a prototype "smart" contact lens to monitor blood glucose levels contained in human tears. The Smart Contact Lens Project, which had been percolating in the top-secret Google X lab for several years, debuted a potential, although long-term, solution for effective blood glucose control in people with diabetes. January 2014: Google Unveils the Smart Contact Lens Here is an excerpt from the January 2014 announcement, via the official Google blog: You've probably heard that diabetes is a huge and growing problem—affecting one in every 19 people on the planet. But you may not be familiar with the daily struggle that many people with diabetes face as they try to keep their blood sugar levels under control. Uncontrolled blood sugar puts people at risk for a range of dangerous complications, some short-term and others longer term, including damage to the eyes, kidneys, and heart. Although some people wear glucose monitors with a glucose sensor embedded under their skin, all people with diabetes must still prick their fingers and test drops of blood throughout the day. It's disruptive, and it's painful. And, as a result, many people with diabetes check their blood glucose less often than they should. We're now testing a smart contact lens that's built to measure glucose levels in tears using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material. … It's still early days for this technology, but we've completed multiple clinical research studies which are helping to refine our prototype. We hope this could someday lead to a new way for people with diabetes to manage their disease. We're in discussions with the FDA, but there's still a lot more work to do to turn this technology Continue reading >>

What Makes Blood Sugar Levels Get Low?
Hypoglycemia (low blood sugar) is uncommon in persons without diabetes. In otherwise healthy adults, fasting (lack of food) is the most common cause of low blood sugars. Medications such as insulin and drugs like alcohol are other primary culprits. Adults who are critically ill can also develop low blood sugars. In rare instances, hormonal disorders or tumors can be the problem. If for any reason you believe you are having symptoms related to low blood sugar that do not improve after eating, see a doctor for help. Hypoglycemia occurs for a variety of different reasons. Certain medications may cause hypoglycemia like insulin taken to lower the blood sugar in people with diabetes. If you have diabetes, your eating, exercising, and medication must be carefully balanced to keep your blood sugar within the normal range. Too much exercise or not enough food, relative to your medication, can cause low blood sugar. In people who do not have diabetes, certain medications, drinking alcoholic beverages, eating disorders, and tumors can cause hypoglycemia. Problems with your liver, kidneys, or the endocrine system may cause hypoglycemia. Sometimes hypoglycemia may occur when the body makes too much insulin in response to eating. A tendency toward hypoglycemia can be hereditary, but dietary carbohydrates usually play a central role in its cause, prevention, and treatment. Simple carbohydrates, or sugars, are quickly absorbed by the body, resulting in a rapid elevation in blood sugar level; this stimulates a corresponding excessive elevation in serum insulin levels, which can then lead to hypoglycemia. Insulin is the hormone responsible for lowering blood sugar by taking sugar out of the blood and putting it into cells. High levels of insulin mean low levels of blood glucose. Normal Continue reading >>
Blood Sugar: What Causes High Blood Sugar Levels In The Morning
There are two reasons why your blood sugar levels may be high in the morning – the dawn phenomenon and the Somogyi effect. The dawn phenomenon is the end result of a combination of natural body changes that occur during the sleep cycle and can be explained as follows: Your body has little need for insulin between about midnight and about 3:00 a.m. (a time when your body is sleeping most soundly). Any insulin taken in the evening causes blood sugar levels to drop sharply during this time. Then, between 3:00 a.m. and 8:00 a.m., your body starts churning out stored glucose (sugar) to prepare for the upcoming day as well as releases hormones that reduce the body's sensitivity to insulin. All of these events happen as your bedtime insulin dose is also wearing off. These events, taken together, cause your body's blood sugar levels to rise in the morning (at "dawn"). A second cause of high blood sugar levels in the morning might be due to the Somogyi effect (named after the doctor who first wrote about it). This condition is also called "rebound hyperglycemia." Although the cascade of events and end result – high blood sugar levels in the morning – is the same as in the dawn phenomenon, the cause is more "man-made" (a result of poor diabetes management) in the Somogyi effect. There are two potential causes. In one scenario, your blood sugar may drop too low in the middle of the night and then your body releases hormones to raise the sugar levels. This could happen if you took too much insulin earlier or if you did not have enough of a bedtime snack. The other scenario is when your dose of long-acting insulin at bedtime is not enough and you wake up with a high morning blood sugar. How is it determined if the dawn phenomenon or Somogyi effect is causing the high blood sug Continue reading >>
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 >>
Is Stress Messing With Your Blood Sugar?
Researchers have linked dozens of physical symptoms to stress overload, from fatigue to weight gain. You can add another symptom to that list: high blood sugar. (Heal your whole body with Rodale's 12-day liver detox for total body health.) When you're stressed, your body is primed to take action. This "gearing up" is what causes your heart to beat faster, your breath to quicken, and your stomach to knot. It also triggers your blood glucose levels to skyrocket. "Under stress, your body goes into fight-or-flight mode, raising blood sugar levels to prepare you for action," says Richard Surwit, PhD, author of The Mind-Body Diabetes Revolution and chief of medical psychology at Duke University in Durham, NC. If your cells are insulin resistant, the sugar builds up in your blood, with nowhere to go, leading to hyperglycemia. We have no shortage of short-term stress in our lives—from traffic jams to working long hours at a demanding job—and our stress hormones, which were designed to deal with short-term dangers like fleeing predators, are turned on for long periods of time, even though we're neither fighting nor fleeing. What we're doing is stewing, which can cause chronically high blood sugar. A prescription to take it easy The good news is, simple relaxation exercises and other stress management techniques can help you gain more control over your blood sugar, according to a study conducted at Duke University. More than 100 people with high blood sugar took five diabetes education classes either with or without stress-management training. After a year, more than half of the stress-relief group improved their blood sugar levels enough to lower their risk for the worst complications, such as heart disease, kidney failure, nerve damage, and vision problems.

Know Your Blood Sugar Numbers: Use Them To Manage Your Diabetes
Checking your blood sugar, also called blood glucose, is an important part of diabetes care. This tip sheet tells you: why it helps you to know your blood sugar numbers how to check your blood sugar levels what are target blood sugar levels what to do if your levels are too low or too high how to pay for these tests Why do I need to know my blood sugar numbers? Your blood sugar numbers show how well your diabetes is managed. And managing your diabetes means that you have less chance of having serious health problems, such as kidney disease and vision loss. As you check your blood sugar, you can see what makes your numbers go up and down. For example, you may see that when you are stressed or eat certain foods, your numbers go up. And, you may see that when you take your medicine and are active, your numbers go down. This information lets you know what is working for you and what needs to change. How is blood sugar measured? There are two ways to measure blood sugar. Blood sugar checks that you do yourself. These tell you what your blood sugar level is at the time you test. The A1C (A-one-C) is a test done in a lab or at your provider’s office. This test tells you your average blood sugar level over the past 2 to 3 months. How do I check my blood sugar? You use a blood glucose meter to check your blood sugar. This device uses a small drop of blood from your finger to measure your blood sugar level. You can get the meter and supplies in a drug store or by mail. Read the directions that come with your meter to learn how to check your blood sugar. Your health care team also can show you how to use your meter. Write the date, time, and result of the test in your blood sugar record. Take your blood sugar record and meter to each visit and talk about your results with your h Continue reading >>
Hyperglycemia: When Your Blood Glucose Level Goes Too High
Hyperglycemia means high (hyper) glucose (gly) in the blood (emia). Your body needs glucose to properly function. Your cells rely on glucose for energy. Hyperglycemia is a defining characteristic of diabetes—when the blood glucose level is too high because the body isn't properly using or doesn't make the hormone insulin. You get glucose from the foods you eat. Carbohydrates, such as fruit, milk, potatoes, bread, and rice, are the biggest source of glucose in a typical diet. Your body breaks down carbohydrates into glucose, and then transports the glucose to the cells via the bloodstream. Body Needs Insulin However, in order to use the glucose, your body needs insulin. This is a hormone produced by the pancreas. Insulin helps transport glucose into the cells, particularly the muscle cells. People with type 1 diabetes no longer make insulin to help their bodies use glucose, so they have to take insulin, which is injected under the skin. People with type 2 diabetes may have enough insulin, but their body doesn't use it well; they're insulin resistant. Some people with type 2 diabetes may not produce enough insulin. People with diabetes may become hyperglycemic if they don't keep their blood glucose level under control (by using insulin, medications, and appropriate meal planning). For example, if someone with type 1 diabetes doesn't take enough insulin before eating, the glucose their body makes from that food can build up in their blood and lead to hyperglycemia. Your endocrinologist will tell you what your target blood glucose levels are. Your levels may be different from what is usually considered as normal because of age, pregnancy, and/or other factors. Fasting hyperglycemia is defined as when you don't eat for at least eight hours. Recommended range without diabet Continue reading >>

What Is A Fasting Blood Sugar Or Fasting Glucose Level?
A fasting blood sugar (FBS) level is the result of a blood sample taken after a patient fasts for at least eight hours. A normal fasting blood sugar level for someone without diabetes is less than 100 mg/dL, or HbA1C below 5.7%. Prediabetes is a fasting blood sugar level from 100 to 125 mg/dL, or HbA1C of 5.7%-6.4%. Diabetes is a fasting blood sugar level of 126 mg/dL and above, or HbA1C of 6.5% or higher. Source: Continue reading >>

Glucose Screening And Glucose Tolerance Tests
Why do I need a glucose screening test during pregnancy? Most healthcare practitioners routinely recommend a glucose screening test (also called a glucose challenge test or GCT) between 24 and 28 weeks of pregnancy to check for gestational diabetes. Gestational diabetes is a high blood sugar condition that some women get during pregnancy. Between 2 and 5 percent of expectant mothers develop this condition, making it one of the most common health problems during pregnancy. And because the condition rarely causes any symptoms, testing is the only way to find out whether you have it. Like any screening test, the GCT won't give you a diagnosis. Instead, it's designed to identify as many women as possible who may have a problem and need more testing to find out. So a positive result doesn't mean that you have gestational diabetes. In fact, only about a third of women who test positive on the glucose screen actually have the condition. If you test positive on the screening, you'll need to take the glucose tolerance test (GTT) – a longer, more definitive test that tells you for sure whether you have gestational diabetes. Your practitioner may want you to be screened earlier than 24 weeks if a routine urine test shows a lot of sugar in your urine or if you're considered high risk. If the results are normal, you'll be screened again at 24 to 28 weeks. Of course, if you were diagnosed with diabetes before pregnancy, you won't need to be screened. Instead, you'll continue to work with your practitioner to manage your condition during pregnancy. How is the glucose screening test done? When you arrive for the test, you're given a sugar solution that contains 50 grams of glucose. The stuff tastes like a very sweet soda pop (it comes in cola, orange, or lime flavor), and you have to 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.
