7 Blood Sugar Testing Mistakes To Avoid
1 / 8 Understand Diabetes Testing If you have diabetes, it's imperative that you learn to effectively self-test your blood sugar to keep your glucose levels in check. For example, results from a study of more than 5,000 people living with diabetes showed that even those people who don't take medication for diabetes have better blood sugar control if they test regularly. The study participants' risk of early kidney damage, strokes, and death from diabetes-related causes was also reduced by one-third. Of course, the accuracy of your results is tied to the accuracy of your checking — and to your understanding of what all the numbers mean. "The most important point to me is that people are learning something from checking their blood sugar," says Sacha Uelmen, RDN, CDE, director of nutrition for the American Diabetes Association. "Don't just look at those numbers, write them down, and move on. If you have diabetes, take an active role in your health." To get the most useful readings, learn these common blood sugar testing mistakes and how to avoid them. Continue reading >>
The Best Time To Check Blood Glucose After A Meal
Q: I was recently diagnosed with type 2 diabetes. Should I check my blood glucose two hours from when I start eating or after I finish eating my meal? A: Most of the food you consume will be digested and raises blood glucose in one to two hours. To capture the peak level of your blood glucose, it is best to test one to two hours after you start eating. The American Diabetes Association recommends a target of below 180 mg/dl two hours after a meal. The American Association of Clinical Endocrinologists recommends a lower target: below 140 mg/dl two hours after a meal. Ask your doctor which target is right for you. Postmeal blood glucose monitoring (and record-keeping) is important because it helps you see how your body responds to carbohydrates in general and particular foods. Managing postmeal blood glucose can help reduce your risk of developing heart and circulation problems.

Prediabetes (impaired Glucose Tolerance)
Pre-diabetes (previously called Impaired Glucose Tolerance IGT) was first named in 2003 and is designed to foster attention and action in people who receive this diagnosis. It is defined as having a blood glucose level that is higher than normal, but not high enough to be classified as diabetes. The cutoff for pre-diabetes is a fasting blood sugar of 100 mg/dl. Fasting levels between 100 and 126 mg/dl are diagnosed as pre-diabetes and a fasting level of 126 mg/dl and up is diabetes. The other determiner of pre-diabetes is a blood sugar level two hours after eating carbs of 140 to 199 mg/dl. A blood sugar under 140 mg/dl is considered normal and one 200mg/dl and over is considered diabetes. Early diagnosis is important. In the early years of pre-diabetes or diabetes, the beta cells are progressively damaged by high blood sugars.Usually by the time diabetes is diagnosed, half of the beta cells are nonfunctional. This can not be reversed so that the beta cells can go back to insulin production. When an early diagnosis of pre-diabetes is made, almost 100 percent of beta cells are functional. If lifestyle changes are made and some diabetes medications are used right away, many beta cells will stay healthy and make blood sugar control easier Criteria for Diagnosing Prediabetes and Diabetes Fasting BG BG 2 Hours After High Carbs Normal 70-99 mg/dl < 140 mg/dl Prediabetes 100-125 mg/dl 140-199 mg/dl Diabetes ≥ 126 mg/dl ≥ 200 mg/dl An estimated 20 million people have pre-diabetes in the U.S. and this number is growing rapidly. 50 percent of the people who have pre-diabetes are likely to develop Type 2 diabetes, however diet, exercise and glucose monitoring can greatly reduce the onset of diabetes altogether. People who have a higher risk of developing pre-diabetes or Type 2 Continue reading >>
Expected Blood Glucose After A High-carb Meal
Blood glucose levels normally rise after a high-carbohydrate meal and drop back to normal levels within a few hours. But if your glucose levels rise higher than normal and recover more slowly, you might have diabetes. Your doctor can administer tests that measure your blood glucose levels immediately before you consume a high-carbohydrate meal and for several hours afterward. If you already have diabetes, your doctor might want you to check your blood glucose levels after meals, to make sure you're keeping your glucose within the expected range. Normal Levels After Eating Healthy, non-diabetic people normally have blood glucose levels of less than 120 milligrams per deciliter two hours after a normal meal, rarely exceeding 140 mg/dL, according to the American Diabetes Association. Levels return to normal within two to three hours. When you undergo a glucose tolerance test, you consume a high-carbohydrate drink or snack containing 75 grams of carbohydrate. At one hour, your test falls into the normal, non-diabetic range if your blood glucose remains below 200 mg/dL. Two hours after your meal, blood glucose should remain below 140 mg/dL. A level of over 200 mg/dL at two hours post-prandial -- which means after a meal -- indicates diabetes. Levels between 140 and 200 mg/dL indicate pre-diabetes, a condition with a strong risk of developing diabetes in the future. Expected Results in Diabetics Diabetics experience larger spikes in blood glucose that take longer to return to baseline. For diabetics, blood glucose an hour after eating should remain below 180 mg/dL or no more than 80 mg/dL over your pre-meal levels. The highest spikes in blood glucose levels often occur after breakfast. If you experience hypoglycemia, or low blood glucose levels before a meal, you might experi Continue reading >>
Why Do People Get Sleepy After Eating?
A slump in mental energy after a meal is what we often call a ‘food coma’. A food coma isn’t an actual coma, but rather a lack of energy you may feel after eating. This state, called post-prandial somnolence, depends on the balance of your meal and how much food you consume. Foods that contain refined carbohydrates, like white bread, white pasta or white rice, can trigger post-prandial somnolence. In addition, the more you eat in one sitting, the more energy you expend on digestion. As food hits the stomach and small intestine, the parasympathetic nervous system becomes more active, stimulating activities that occur when the body is at rest, such as during digestion. The more food you consume, the more your body will want to be at rest. Consuming food, especially with carbohydrate-rich treats, also causes hormonal and neurochemical changes. After eating, your body increases the amount of sugar, or glucose, circulating in your blood stream. To counter this surge in blood sugar, your body releases insulin to mop up excess glucose in the blood and return your blood sugar back to a normal range. The increase in insulin causes a cascade of events, causing the brain to produce more serotonin and melatonin—two neurochemicals that have been shown to leave you feeling sleepy. This process sucks up energy and may last about an hour. But can you prevent this slump in mental energy? You can decrease how much your blood glucose spikes by eating four to five smaller meals a day rather than stuffing yourself at three meals. Another way to avoid post-prandial somnolence is to consume fewer carbohydrates or switch to whole grains. Drinking water to aid digestion and avoiding sugary beverages will also prevent sudden spikes in blood sugar. In addition, moving around after a meal Continue reading >>
High Blood Sugar After Exercise?
back to Overview Markus, one of our great German-language authors, wrote about struggling with high blood sugar after exercise. I know it's a common problem, and one I've struggled with personally, so I want to make sure you get to see it, too. From Markus Berndt: It’s one of the first recommendations you get after being diagnosed with diabetes. “Get active, do more exercise, it’s good for you!” And since we’ve been a child we’ve heard that exercise is healthy. If we do it consistently we’re rewarded, literally, with an awesome beach body. Adding exercise into our day is also good for our diabetes. We’re taught that exercise lowers blood sugar, right? But can the opposite also be true? Can you have high blood sugar after exercise? Up close We now know that physical activity usually lowers blood sugar because it reduces how much insulin is needed to move sugar into the cells. While, in the past, most experts advised frequent training intervals at moderate intensity, but recent studies have shown that even short, intense workouts are very effective. For example, a 15-minute intense weight training lowered blood sugar even more than what’s seen in some endurance training. So activity lowers blood sugar – but not always! Personally, I experienced this very early on and was extremely irritated! I just learned that exercise lowers blood sugar, but an intense 45-minute run consistently resulted in higher blood sugars than when I started! What in the world? At first, I was confused and felt like I didn’t understand the world anymore. Then it was more of a “would you look at this?” kind of thing. And finally, I was determined to figure out what was happening. I knew there had to be an explanation. Why does exercise sometimes raise blood sugar? Exercise Continue reading >>
Postprandial Glucose Test
Changes in blood glucose over time following a high and low glycemic index (GI) carbohydrate. A postprandial glucose test is a blood glucose test that determines the amount of a type of sugar, called glucose, in the blood after a meal. Glucose is mainly made from carbohydrate foods. It is the main source of energy used by the body. Normally, blood glucose levels increase slightly after eating. This increase causes the pancreas to release insulin, which assists the body in removing glucose from the blood and storing it for energy. People with diabetes may not produce or respond properly to insulin, which causes their blood glucose to remain elevated. Blood glucose levels that remain high over time can damage the eyes, kidneys, nerves, and blood vessels. A 2-hour postprandial blood glucose test ("2 hour p.c. blood glucose test", etc.) measures blood glucose exactly 2 hours after eating a meal, timed from the start of the meal.  By this point blood sugar has usually gone back down in healthy people, but it may still be elevated in people with diabetes. Thus, it serves as a test of whether a person may have diabetes, or of whether a person who has diabetes is successfully controlling their blood sugar. Purpose Blood glucose tests are done to: Check for and monitor the treatment of diabetes. Check for diabetes that occurs during pregnancy gestational diabetes. Determine if an abnormally low blood sugar level hypoglycemia is present. Procedure For a 2-hour postprandial test, a meal is eaten exactly 2 hours before the blood sample is taken. A home blood sugar test is the most common way to check 2-hour postprandial blood sugar levels. The health professional taking a blood sample will: Wrap a tourniquet around the upper arm to stop the flow of blo Continue reading >>

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). This pro Continue reading >>
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 >>
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 >>
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 >>
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 >>

A1c Tip: Look At Your Blood Sugar After You Eat
Frustrated with your latest A1C test results? Your blood sugar levels within the 1-3 hours after you eat are just as important as your blood sugar right before you eat, especially when it comes to your A1C. For example, if your blood sugar is regularly rising to 240 mg/dL (13 mmol) after a meal, that means that you could be spending 2-3 hours after every meal with your blood sugar in that range…which adds up to at least 9 hours of the day! That’s a good chunk of the day spent with high blood sugars, and possibly the source of your A1C results. What can you do to prevent that blood sugar spike after a meal? Here are 5 tips: 1. Take your insulin or oral medication sooner before you eat. Today’s fast-acting insulin’s are designed to reach your bloodstream and start working within 10 to 30 minutes. That means that if you eat your meal and then take your insulin, you’re giving the carbohydrates in that food 10 to 30 minutes to start spiking your blood sugar, easily enough time to work its way up to 200 mg/dL (11 mmol) or higher by the time the insulin really gets going. 2. Talk to your doctor about a medication like Symlin. Symlin is an injectable medication designed to replace the hormone “amylin.” Amylin is a hormone in the human body that works to prevent food from digesting as quickly and it helps prevent high blood sugars after eating. People with type 1 diabetes make zero amylin and people with type 2 diabetes make some, but often not enough. While you can certainly live a healthy life with diabetes without Symlin (or amylin), it can be very helpful for those with insulin resistance or difficulty with high blood sugar after meals. 3. Fine-tune your insulin doses for meals. If you’re taking insulin with your meals, it’s vital that you test your insulin Continue reading >>
Blood Sugar Level During Pregnancy, What's Normal?
The form of diabetes which develops during pregnancy is known as gestational diabetes. This condition has become predominant in the recent pastaccording to the 2009 article in American Family Physician. For instance, in the United States alone, it affects around 5% to 9% of all the pregnant women. Pregnancy aggravates the preexisting type 2 and type 1 diabetes. During pregnancy the sugar level may tend to be high sometimes, posing problems to the mother and the infant as well. However, concerning the sugar level during pregnancy, what's normal? Blood sugar control is one of the most essential factors that should be undertaken during pregnancy. When measures are taken to control blood sugar level during pregnancy, it increases chances of a successful pregnancy. The average fasting glucose for pregnant women without any diabetes condition range from 69 to 75 and from 105 to 108 immediately one hour after consuming food. If you have preexisting diabetes or you have developedgestational diabetes, the best way to handle the blood sugar level is to ensure that it remains in between the normal range, not going too low or high. According to the recommendations of the 2007, Fifth International Workshop-Conference on Gestational Diabetes, which established blood glucose goals especially for diabetic women, during the period of pregnancy, the fasting blood sugar should not exceed 96. Blood sugar should remain below 140 just one hour after eating and below 120 two hours later. Why Is It Important to Keep Normal Blood Sugar Level During Pregnancy? The most effective way to prevent complications related to diabetes is to control the amount or the level of blood sugar. This blood sugar control is very significant during pregnancy as it can: Minimize the risk of stillbirth as well as m Continue reading >>
Why Your “normal” Blood Sugar Isn’t Normal (part 2)
Hi, I just found this site and would like to participate. I will give my numbers, etc. First, my last A1c was 6.1, the doc said it was Pre-diabetes in January of 2014, OK, I get it that part, but what confuses me is that at home, on my glucometer, all my fastings were “Normal” however, back then, I had not checked after meals, so maybe they were the culprits. Now, I am checking all the time and driving myself crazy. In the morning sometimes fasting is 95 and other times 85, it varies day to day. Usually, after a low carb meal, it drops to the 80’s the first hour and lower the second. On some days, when I am naughty and eat wrong, my b/s sugar is still low, and on other days, I can eat the same thing, and it goes sky high, again, not consistent. Normally, however, since February, my fbs is 90, 1 hour after, 120, 2nd hour, back to 90, but, that changes as well. In February, of 2014, on the 5th, it was horrible. I think I had eaten Lasagne, well, before, my sugars did not change much, but that night, WHAM-O I started at 80 before the meal, I forgot to take it at the one and two hour mark, but did at the 3 hour mark, it was 175, then at four hours, down to 160, then at 5 hours, back to 175. I went to bed, because by that time, it was 2 AM, but when I woke up at 8:00 and took it, it was back to 89!!!! This horrible ordeal has only happened once, but, I have gone up to 178 since, but come down to normal in 2 hours. I don’t know if I was extra stressed that day or what, I am under tons of it, my marriage is not good, my dear dad died 2 years ago and my very best friend died 7 months ago, I live in a strange country, I am from America, but moved to New Zealand last year, and I am soooo unhappy. Anyway, what does confuse me is why the daily differences, even though I may Continue reading >>
