Diabetes And Hyperglycemia
Tweet Hyperglycemia occurs when people with diabetes have too much sugar in their bloodstream. Hyperglycemia should not be confused with hypoglycemia, which is when blood sugar levels go too low. You should aim to avoid spending long periods of time with high blood glucose levels. What is hyperglycemia? Hyperglycemia, the term for expressing high blood sugar, has been defined by the World Health Organisation as: Blood glucose levels greater than 7.0 mmol/L (126 mg/dl) when fasting Blood glucose levels greater than 11.0 mmol/L (200 mg/dl) 2 hours after meals Although blood sugar levels exceeding 7 mmol/L for extended periods of time can start to cause damage to internal organs, symptoms may not develop until blood glucose levels exceed 11 mmol/L. What causes hyperglycemia? The underlying cause of hyperglycemia will usually be from loss of insulin producing cells in the pancreas or if the body develops resistance to insulin. More immediate reasons for hyperglycemia include: Missing a dose of diabetic medication, tablets or insulin Eating more carbohydrates than your body and/or medication can manage Being mentally or emotionally stressed (injury, surgery or anxiety) Contracting an infection What are the symptoms of hyperglycemia? The main 3 symptoms of high blood sugar levels are increased urination, increased thirst and increased hunger. High blood sugar levels can also contribute to the following symptoms: Regular/above-average urination Weakness or feeling tired Increased thirst Vision blurring Is hyperglycemia serious? Hyperglycemia can be serious if: Blood glucose levels stay high for extended periods of time - this can lead to the development of long term complications Blood glucose levels rise dangerously high - this can lead to short term complications In the shor Continue reading >>
What A High Blood Sugar Feels Like? Signs & Symptoms Of Hyperglycemia
I get my first cup of coffee and sit on the sun deck with the birds singing. I feel as if I have not slept a wink, and my head aches. I could go back to bed and sleep all day, but work awaits. It’s a beautiful, sunny day, but my body feels heavy, and stuck to the chair. It hurts to lift my arms. My blood sugar was 381 this morning. Again. I think about having to face the day at the office. Driving down the interstate, the lines are blurry. I know that if the DMV got wind of it, I might not be driving as high as my A1C had been. When I get to the office, I walk in with a dark fog feeling surrounding me, and take some deep breaths at my desk. As I begin to review the end of the month reports, the numbers get fuzzy, and I can’t concentrate on them. My 36 ounce water bottle with only a few sips left beads sweat on the desk, and it’s across the building to get to the bathroom. Sometimes it’s a race to get there in time. My body is taught and swollen, like the Blueberry Girl from Willy Wonka’s Chocolate Factory. My blood sugar is a blue river of sticky blueberry filling as I roll down the hall toward the bathroom. I feel that if I had a needle, I could pop myself. That would surely be a mess. My skin is so dry and flaky that no amount of lotion will hydrate it. No amount of water can quench my thirst, and my mouth feels like the Sahara Desert. With one hand on the water cooler, and the other hand on the bathroom door, I guzzled down what I could until the feeling hit that I wasn’t going to be able to wait any longer. I was out of regular insulin, and I had taken my long acting insulin. I was not so patiently waiting for it to kick in. This morning was not starting out so well. I’d have to tackle the reports in my current brain fog. I did have a doctor’s appoin Continue reading >>
High Blood Sugar Symptoms
If you’ve had diabetes for any length of time at all, you’ve probably seen lists of the signs and symptoms of high blood glucose dozens of times. Doctors and diabetes educators hand them out. Hundreds of websites reprint them. Most diabetes books list them. You likely know some of the items on the list by heart: thirst, frequent urination, blurry vision, slow healing of cuts, and more. But have you ever stopped to wonder why these symptoms occur? How does high blood glucose cause frequent urination, make your vision go blurry, or cause all of those other things to happen? Here are some answers to explain what’s going on in your body when you have high blood glucose. Setting the stage for high blood glucose High blood glucose (called hyperglycemia by medical professionals) is the defining characteristic of all types of diabetes. It happens when the body can no longer maintain a normal blood glucose level, either because the pancreas is no longer making enough insulin, or because the body’s cells have become so resistant to insulin that the pancreas cannot keep up, and glucose is accumulating in the bloodstream rather than being moved into the cells. What is high blood sugar? Blood glucose is commonly considered too high if it is higher than 130 mg/dl before a meal or higher than 180 mg/dl two hours after the first bite of a meal. However, most of the signs and symptoms of high blood glucose don’t appear until the blood glucose level is higher than 250 mg/dl. Some of the symptoms have a rapid onset, while others require a long period of high blood glucose to set in. It’s important to note that individuals differ in their sensitivity to the effects of high blood glucose: Some people feel symptoms more quickly or more strongly than others. But each sign or sympt Continue reading >>
High Blood Sugar In Dogs
Hyperglycemia in Dogs A dog with abnormally high levels of glucose in the blood is said to have hyperglycemia. A simple carbohydrate sugar that circulates in the blood, glucose is a major source of energy for the body, of which normal levels range between 75-120mg. Insulin, a hormone that is produced and released by the pancreas into the bloodstream when glucose levels rise, plays a key role in maintaining normal sugar levels. Low levels or absolute deficiency of insulin results in abnormally high blood sugar levels. Some of the causes for hyperglycemia may be pancreatitis, and the resulting inability to produce insulin; normally occurring hormones, especially in female dogs; diet; and infections of the body (such as teeth, or urinary tract). Middle aged and older dogs are more at risk for developing hyperglycemia, and it is more common in female dogs than in males. Any breed can be affected, but some smaller breeds appear to be more disposed, including beagles, cairn terriers, dachshunds, miniature poodles and schnauzers. Symptoms and Types Clinical symptoms may vary depending on the underlying disease/condition. Your dog may not be showing any serious symptoms, especially those if the increased sugar is thought to be temporary, hormonal, or stress induced hyperglycemia. Some of the more common symptoms include: Depression Weight loss Excessive hunger Dehydration Bloodshot eyes (due to inflamed blood vessels) Liver enlargement Nerve damage in legs Severe depression (in cases of very high blood sugar levels) Non-healing wounds;infection is increased as the excess sugar feeds fungal and bacterial invaders Tissue damage (due to oxidizing [burning] effect of the excess sugar in the tissue) Causes Other than high stress situations, harmful drug interactions (such as with he Continue reading >>
Why Does High (or Low) Blood Sugar Give Me Headaches?
Susan B. Sloane, BS, RPh, CDE, has been a registered pharmacist for more than 20 years and a Certified Diabetes Educator for more than 15 years. Her two sons were diagnosed with diabetes, and since then, she has been dedicated to promoting wellness and optimal outcomes as a patient advocate, information expert, educator, and corporate partner. Headaches can be debilitating, and patients with diabetes can get headaches from blood sugars dropping too low or climbing too high. As if we didn’t have enough to think about, right? There are many factors that can trigger headaches or even migraines, and blood sugar fluctuations are just one of those factors. The key to avoiding blood sugar-related headaches is keeping blood sugars from spiking or dropping too rapidly. For example, when you are treating a low blood sugar, don’t go on a high carbohydrate-eating binge, even though you may be ravenous. Eat a sensible meal with some protein as directed by your healthcare provider. When blood sugar is too low One of the suspected causes of low blood sugar-caused headaches has to do with the blood vessels in your brain. Your brain needs a readily available supply of glucose in order to function properly. If the brain senses it does not have enough sugar, blood vessels in the brain can spasm, triggering a headache. In the fasting state, stress hormones are also released which can cause vasoconstriction leading to headache. There is also a type of headache that can be seen in patients with diabetes that experience frequent low blood sugars, which are followed by rebound high blood sugars. This rebound phenomenon is often due to hormones that the body releases in response to a low blood sugar in an attempt to regulate itself. When blood sugar is too high High blood sugars can cause l Continue reading >>
What Is Hyperglycemia?
Hyperglycemia, a high level of sugar in the blood, is a hallmark of diabetes. Your blood sugar levels fluctuate over the course of a day: Levels are higher right after meals, as carbohydrates are broken down into glucose (sugar), and lower after exercise, when glucose has been burned to fuel the activity. In someone who doesn't have diabetes, blood sugar levels stay within a narrow range. Between meals, the concentration of sugar in the blood ranges from about 60 to 100 mg/dl (milligrams per deciliter). After meals it may reach 120 to 130 mg/dl, but rarely goes higher than 140 mg/dl. But if you have type 2 diabetes, blood sugar levels can go much higher — to 200, 300, or even 400 mg/dl and beyond — and will go much higher unless you take the necessary steps to bring them down. Hyperglycemia Symptoms High blood sugar doesn't always produce symptoms, so it's important to check your blood sugar regularly, as indicated by your doctor. Hyperglycemia symptoms include: Frequent urination Extreme thirst Feeling tired and weak Blurry vision Feeling hungry, even after eating Causes of Hyperglycemia If you've been diagnosed with type 2 diabetes, a treatment plan is put in place to lower blood sugar and keep it as close to the normal range as possible. But even after you start treatment, you may still develop hyperglycemia at times. When you have diabetes, it's almost impossible not to have hyperglycemia — and high blood sugar can happen for no identifiable reason. Some of the reasons blood sugar may go too high include: Missing prescribed medicines or taking medication at the wrong times or in the wrong amounts High food intake or larger consumptions of carbohydrate than expected or intended Lack of sleep Emotional stress Intense exercise Illness is another important — and Continue reading >>
Hyperglycaemia (high Blood Sugar)
Hyperglycaemia is the medical term for a high blood sugar (glucose) level. It's a common problem for people with diabetes. It can affect people with type 1 diabetes and type 2 diabetes, as well as pregnant women with gestational diabetes. It can occasionally affect people who don't have diabetes, but usually only people who are seriously ill, such as those who have recently had a stroke or heart attack, or have a severe infection. Hyperglycaemia shouldn't be confused with hypoglycaemia, which is when a person's blood sugar level drops too low. This information focuses on hyperglycaemia in people with diabetes. Is hyperglycaemia serious? The aim of diabetes treatment is to keep blood sugar levels as near to normal as possible. But if you have diabetes, no matter how careful you are, you're likely to experience hyperglycaemia at some point. It's important to be able to recognise and treat hyperglycaemia, as it can lead to serious health problems if left untreated. Occasional mild episodes aren't usually a cause for concern and can be treated quite easily or may return to normal on their own. However, hyperglycaemia can be potentially dangerous if blood sugar levels become very high or stay high for long periods. Very high blood sugar levels can cause life-threatening complications, such as: diabetic ketoacidosis (DKA) – a condition caused by the body needing to break down fat as a source of energy, which can lead to a diabetic coma; this tends to affect people with type 1 diabetes hyperosmolar hyperglycaemic state (HHS) – severe dehydration caused by the body trying to get rid of excess sugar; this tends to affect people with type 2 diabetes Regularly having high blood sugar levels for long periods of time (over months or years) can result in permanent damage to parts Continue reading >>
Could Slightly High Blood Sugar Cause Neuropathy?
My glucose levels usually run between 120 and 135 with a nonfasting blood test, though do not have a diagnosis of diabetes. I suffer greatly with my feet and been told by a podiatrist that it is neuropathy. Is it possible that my high glucose levels are causing the neuropathy? Dear Terry, Thanks for your question. I like to think of blood glucose values as a spectrum of numbers with no clear cutoff between nondiabetic and diabetic. In similar manner there is a gray area of blood glucose that defines pre-diabetes. Many people use blood sugar and blood glucose interchangeably. The definition of diabetes has changed over time. The numbers you quote might very well be considered diagnostic of diabetes today whereas they were not 20 years ago. In 1997, the American Diabetes Association definition of normal blood glucose decreased from 120 to 110 mg/dL (6.1 mmol/L). In 2002, the American Diabetes Association defined a normal fasting blood glucose as less than 100 mg/dL (5.6 mmol/L). Today we consider fasting blood sugars of 100 mg/dl to 125mg/dl to be in the realm of glucose intolerance which is sometimes called pre-diabetes. These patients are at increased risk for developing frank diabetes. Several fasting glucose levels over 125 or a single random glucose over 200 mg are considered diagnostic of diabetes. There are other tests used to make the diagnosis of pre-diabetes or diabetes. Pre-diabetes is defined as a blood sugar of 140 to 199 mg/dL (7.8 to 11.0 mmol/L) two-hour after drinking 75 grams of an oral glucose solution. The diagnosis of diabetes is confirmed with a blood sugar of 200 mg/dL or greater, two hours after ingestion of the glucose solution. Hemoglobin A1C is a blood test that gives an estimate of blood sugar levels over the previous three months. Persons with Continue reading >>
Hyperglycemia (high Blood Sugar)
Hyperglycemia is a hallmark sign of diabetes (both type 1 diabetes and type 2 diabetes) and prediabetes. Other conditions that can cause hyperglycemia are pancreatitis, Cushing's syndrome, unusual hormone-secreting tumors, pancreatic cancer, certain medications, and severe illnesses. The main symptoms of hyperglycemia are increased thirst and a frequent need to urinate. Severely elevated glucose levels can result in a medical emergency like diabetic ketoacidosis (DKA) or hyperglycemic hyperosmolar nonketotic syndrome (HHNS, also referred to as hyperglycemic hyperosmolar state). Insulin is the treatment of choice for people with type 1 diabetes and for life-threatening increases in glucose levels. People with type 2 diabetes may be managed with a combination of different oral and injectable medications. Hyperglycemia due to medical conditions other than diabetes is generally treated by treating the underlying condition responsible for the elevated glucose. Blood Sugar Swings: Tips for Managing Diabetes & Glucose Levels A number of medical conditions can cause hyperglycemia, but the most common by far is diabetes mellitus. Diabetes affects over 8% of the total U.S. population. In diabetes, blood glucose levels rise either because there is an insufficient amount of insulin in the body or the body cannot use insulin well. Normally, the pancreas releases insulin after a meal so that the cells of the body can utilize glucose for fuel. This keeps blood glucose levels in the normal range. Type 1 diabetes is responsible for about 5% of all cases of diabetes and results from damage to the insulin-secreting cells of the pancreas. Type 2 diabetes is far more common and is related to the body's inability to effectively use insulin. In addition to type 1 and type 2, gestational diabe Continue reading >>
High Blood Glucose: What It Means And How To Treat It
What is high blood glucose? People who do not have diabetes typically have fasting plasma blood glucose levels that run under 100 mg/dl. Your physician will define for you what your target blood glucose should be — identifying a blood glucose target that is as close to normal as possible that you can safely achieve given your overall medical health. In general, high blood glucose, also called 'hyperglycemia', is considered "high" when it is 160 mg/dl or above your individual blood glucose target. Be sure to ask your healthcare provider what he or she thinks is a safe target for you for blood glucose before and after meals. If your blood glucose runs high for long periods of time, this can pose significant problems for you long-term — increased risk of complications, such as eye disease, kidney disease, heart attacks and strokes and more. High blood glucose can pose health problems in the short-term as well. Your treatment plan may need adjustment if the blood glucose stays over 180 mg/dl for 3 days in a row. It is important to aim to keep your blood glucose under control, and treat hyperglycemia when it occurs. What are the symptoms of high blood glucose? Increased thirst Increased urination Dry mouth or skin Tiredness or fatigue Blurred vision More frequent infections Slow healing cuts and sores Unexplained weight loss What causes high blood glucose? Too much food Too little exercise or physical activity Skipped or not enough diabetes pills or insulin Insulin that has spoiled after being exposed to extreme heat or freezing cold Stress, illness, infection, injury or surgery A blood glucose meter that is not reading accurately What should you do for high blood glucose? Be sure to drink plenty of water. It is recommended to drink a minimum of 8 glasses each day. If yo Continue reading >>

How To Lower Your Blood Sugar When It's Really High
This article is written for type 2 diabetics who need help coming down from a very high blood sugar during a single, isolated high blood sugar event. If you want to try an stabilize your baseline, consider signing up for my Baseline Blood Sugar Challenge course. THIS ARTICLE IS NOT A SUBSTITUTE FOR REAL MEDICAL ADVICE. If you're a type 2 diabetic and your blood sugar is high right now (greater than 300mg/dL for at least 6 hours), the first thing you should do is call your doctor. So, if you haven't called anyone for help yet, please stop reading this article and call your doctor. If your doctor is able to help, then you need not read on. Also, if you are having symptoms of Diabetic Ketoacidosis, stop reading this article and go to the hospital immediately. Diabetic Ketoacidosis can kill you if left untreated. But. If you're in a situation where your blood sugar has been high for an extended period of time, you could perhaps consider taking the following steps to solve your blood sugar problem. Disclaimer: This is friendly, non-medical advice from a random diabetic person you don't even know, which is a very (very) poor substitute for real, actual medical advice. Use at your own risk. First, you should try and lower your blood sugar without injectable insulin by completing the following steps: 1. Check your blood sugar. Write down the time and your blood sugar level. 2. Drink water (this doesn't actually lower blood sugar, but it helps flush sugar and ketones from your body, if you have them). Continue drinking water, but please don't make yourself sick. 3. Move. As in, walk. Walk around the block or walk in place or haul your ass up and down the stairs for 30-60 minutes. Walking helps your cells become less insulin resistant, which is what you need right now. Do N Continue reading >>
8 Sneaky Things That Raise Your Blood Sugar Levels
Skipping breakfast iStock/Thinkstock Overweight women who didn’t eat breakfast had higher insulin and blood sugar levels after they ate lunch a few hours later than they did on another day when they ate breakfast, a 2013 study found. Another study in the American Journal of Clinical Nutrition found that men who regularly skipped breakfast had a 21 percent higher chance of developing diabetes than those who didn’t. A morning meal—especially one that is rich in protein and healthy fat—seems to stabilize blood sugar levels throughout the day. Your breakfast is not one of the many foods that raise blood sugar. Here are some other things that happen to your body when you skip breakfast. Artificial sweeteners iStock/Thinkstock They have to be better for your blood sugar than, well, sugar, right? An interesting new Israeli study suggests that artificial sweeteners can still take a negative toll and are one of the foods that raise blood sugar. When researchers gave mice artificial sweeteners, they had higher blood sugar levels than mice who drank plain water—or even water with sugar! The researchers were able to bring the animals’ blood sugar levels down by treating them with antibiotics, which indicates that these fake sweeteners may alter gut bacteria, which in turn seems to affect how the body processes glucose. In a follow-up study of 400 people, the research team found that long-term users of artificial sweeteners were more likely to have higher fasting blood sugar levels, reported HealthDay. While study authors are by no means saying that sugary beverages are healthier, these findings do suggest that people who drink artificially sweetened beverages should do so in moderation as part of a healthy diet. Here's what else happens when you cut artificial sweetener Continue reading >>
When Your Blood Sugar Is Too High Or Too Low
Sometimes, no matter how hard you try to keep your blood sugar in the range your doctor has advised, it can be too high or too low. Blood sugar that is too high or too low can make you very sick. Here's how to handle these emergencies. What You Need to Know about High Blood Sugar If your blood sugar stays over 240, it is too high. High blood sugar usually comes on slowly. It happens when you don't have enough insulin in your body. High blood sugar can happen if you miss taking your diabetes medicine, eat too much, or don't get enough exercise. Sometimes, medicines you take for other problems may cause high blood sugar. Be sure to tell your doctor about other medicines you take. This chart shows the ranges of blood sugar. Having an infection or being sick or under stress can also make your blood sugar too high. That is why it is very important to test your blood and keep taking your medicine (insulin or diabetes pills) when you have an infection or are sick. Your blood sugar may be too high if you are very thirsty and tired, have blurry vision, are losing weight fast, and have to go to the bathroom often. Very high blood sugar may make you feel sick to your stomach, faint, or throw up. It can cause you to lose too much fluid from your body. Testing your blood sugar often, especially when you are sick, will warn you that your blood sugar may be rising too high. If your blood sugar stays over 300 when you check it two times in a row, call your doctor. You may need a change in your insulin shots or diabetes pills, or a change in your meal plan. *CGM-based treatment requires fingersticks for calibration, if patient is taking acetaminophen, or if symptoms/expectations do not match CGM readings, and if not performed, may result in hypoglycemia.

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 >>
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 >>
