Is Diabetes Hyperglycemia Or Hypoglycemia?

How To Tell The Difference Between Hyperglycemia And Hypoglycemia

How To Tell The Difference Between Hyperglycemia And Hypoglycemia

The differences between these extremes Pressmaster /Shutterstock Either one of these conditions could be part of silent diabetes symptoms you might be missing—they both involve difficulty regulating blood sugar, or glucose. But even non-diabetics can be susceptible to blood sugar extremes, called hyperglycemia and hypoglycemia. "Hyperglycemia is defined as abnormally high blood sugar levels," says Tanya Zuckerbrot, MS, RD, a New York City-based dietitian, bestselling author, and founder of The F-Factor Diet. "It occurs when the body does not have enough insulin to bring glucose into the cells for energy." In other words, you have an overload of sugar, more than your body can handle. On the other hand, "hypoglycemia is defined as abnormally low blood sugar levels," she says. "When blood sugar begins to fall, a hormone called glucagon signals the liver to release stored glucose to raise blood sugar back to normal. If this does not occur you experience hypoglycemia." Warning signs for hyperglycemia Andrey Popov /Shutterstock One of the good things that happen to your body when you stop eating sugar is avoiding hyperglycemia. How can you know if you may be experiencing this sugar overload? "Hyperglycemia symptoms can include thirst, urination, blurry vision, and depending on the severity, dizziness, nausea, and vomiting, or reduced concentration and awareness," says Kathleen Dungan, MD, an endocrinologist at The Ohio State University Wexner Medical Center. "It is important to note that depending upon the severity, hyperglycemia may not cause any symptoms at all." This is why people with diabetes need to monitor their blood sugar, and take insulin to help the body absorb it. Be on the lookout for hypoglycemia symptoms One of the medical reasons you're always hungry could b Continue reading >>

What Is The Difference Between Hyperglycemia And Hypoglycemia?

By Debra A. Sokol-McKay, MS, CVRT, CDE, CLVT, OTR/L, SCLV What Is Hyperglycemia? In relation to diabetes, hyperglycemia refers to chronically high blood glucose levels. Most medical professionals define hyperglycemia by using the blood glucose goals that you and your physician have established and combining those goals with the blood glucose target ranges set by the American Diabetes Association. It's important to understand that you'll probably experience high blood glucose levels from time to time, despite your best efforts at control. As with any chronic disease, talk with your physician and diabetes care team if the pattern of your blood glucose readings is consistently higher or lower than your blood glucose goals. Complications from Hyperglycemia Persistent hyperglycemia can cause a wide range of chronic complications that affect almost every system in your body. When large blood vessels are affected, it can lead to: Stroke (cerebral vascular disease) Heart attack or Congestive Heart Failure (coronary heart disease) Circulation disorders and possible amputation (peripheral vascular disease) When smaller blood vessels are affected, it can lead to: Kidney disease (nephropathy) Nerve damage (neuropathy) Diabetic eye disease (retinopathy) Joseph Monks: Writer, Producer, and Film Director Joseph Monks, who has diabetic retinopathy, creates and produces films for his production company Sight Unseen Pictures. He is also the first blind filmmaker to direct a feature film. Says Joe, "I'm not uncomfortable with the term 'blind.' I'm not thrilled about it, of course, but it's accurate. The lights went out for me in early 2002 as a result of diabetic retinopathy—the death of my retinas. It is what it is, so when it happened, I decided that I wasn't going to let it put an en Continue reading >>

Hypoglycemia In An Individual With Diabetes

Hypoglycemia In An Individual With Diabetes

Hypoglycemia (low blood sugar) is a frequent event that can harm the quality of life of people with diabetes and their families. It is important to know the symptoms and how to treat it, as well as its causes and what to do to prevent it. Definition Hypoglycemia is defined as a blood glucose (sugar) level below 4 mmol/L, with or without symptoms. People at risk Some people with diabetes are at greater risk of hypoglycemia than others: *Gliclazide (Diamicron® and Diamicron®), Glimepiride (Amaryl®), Glyburide (Diabeta®), Nateglinide (Starlix®), Repaglinide (GlucoNorm®). Symptoms The symptoms of hypoglycemia fall into two categories. Symptoms caused by adrenaline secretion (adrenergic) These symptoms are usually the first to appear and should be considered "alarm bells": Trembling Palpitations Sweating Anxiety Hunger Nausea Tingling Pallor Symptoms caused by a lack of glucose in the brain (neuroglycopenic) If nothing is done, the following symptoms may occur: Difficulty concentrating Mood swings Confusion Weakness Drowsiness Blurred vision Difficulty speaking Headache Dizziness Moreover, if hypoglycemia occurs during the night, a person could experience: Profuse sweating Nightmares Restless sleep Headache upon awakening The symptoms can vary from person to person and from one episode to another. Sometimes no symptoms appear, particularly in people who have been diabetic for a long time or if blood glucose levels drop slowly. 3 levels of severity Mild hypoglycemia Symptoms caused by the production of adrenaline; The person is able to self-treat. Moderate hypoglycemia Symptoms caused by the production of adrenaline and a lack of glucose to the brain; The person is able to self-treat. Severe hypoglycemia Blood glucose usually less than 2.8 mmol/L; The individual require Continue reading >>

The animals were maintained in a hyper- or hypoglycemic state by treatment with insulin for 3 months. Nondiabetic siblings served as controls. Qualitative analysis of the gastrocnemius and sural nerves by light and electron microscopy revealed signs of Wallerian-type axonal degeneration and regeneration of large myelinated fibers in the hypoglycemic but not the hyperglycemic animals. Degeneration was more common in the gastrocnemius nerve than in the sural nerve. In hypoglycemic rats, myelinated fibers in both the gastrocnemius and sural nerves had significantly shorter internodes and smaller diameters. The decreased fiber diameter was related (r = 0.9) to the duration of severe hy Continue reading >>

Hypoglycemia (diabetic) & Hyperglycemia

Hypoglycemia (diabetic) & Hyperglycemia

Definition Hypoglycemia is defined as a low blood sugar (glucose) level. Hyperglycemia is defined as too high a blood sugar (glucose) level. Description As you regulate your blood glucose and keep your diabetes record, there are two problems that you need to be able to recognize and treat (with your personal physician’s advice): hypoglycemia and hyperglycemia. Hypoglycemia: Hypoglycemia, or an insulin reaction, can happen if you are taking insulin or oral medications. Hypoglycemia means low blood glucose. This reaction happens when there is not enough glucose in your blood. A hypoglycemic reaction usually comes on very suddenly. It often happens at the time when insulin action is at its peak, during or after strenuous exercise or when a meal is delayed. Most people learn to recognize their own symptoms to an insulin reaction. If you begin feeling any symptoms or think your blood glucose may be too low, the best way to be sure is to check your blood level using a blood glucose test strip. If your blood glucose is less than 70 mg/dl, then you are probably having a hypoglycemic reaction. Hyperglycemia: Hyperglycemia, or high blood glucose, is the condition found in individuals with diabetes, either insulin-dependent or non-insulin-dependent. Causes The most common causes of hypoglycemia are: 1. too much insulin, 2. too much exercise, or 3. not enough food Hyperglycemia usually occurs slowly, over several hours or days. It may be caused by: 1. not taking enough insulin 2. illness (such as a cold or flu) 3. infection 4. eating too much 5. stress 6. certain medications Symptoms Symptoms that you may notice with hypoglycemia are: sweating weakness anxiety trembling fast heartbeat inability to think straight irritability grouchiness hunger headache sleepiness Signs and sympto Continue reading >>

Hyperglycemia And Hypoglycemia In Type 2 Diabetes

Hyperglycemia And Hypoglycemia In Type 2 Diabetes

Hyperglycemia can occur when blood sugar levels are too high. People develop hyperglycemia if their diabetes is not treated properly. Hypoglycemia sets in when blood sugar levels are too low. It is usually a side effect of treatment with blood-sugar-lowering medication. Diabetes is a metabolic disease with far-reaching health consequences. In type 2 diabetes, not enough insulin is released into the bloodstream, or the insulin cannot be used properly. In type 1 diabetes, the body only produces very little insulin, or none at all. We need insulin to live. Without it, sugar (glucose) builds up in the blood because it cannot be taken out and used by the body. Very high blood sugar, known as hyperglycemia, leads to a number of symptoms. If blood sugar levels are too low, it is called hypoglycemia. When is blood sugar considered to be too high or too low? Slight fluctuations in blood sugar levels are completely normal and also happen on a daily basis in people who do not have diabetes. Between around 60 and 140 milligrams of sugar per deciliter of blood (mg/dL) is considered to be healthy. This is equivalent to between 3.3 and 7.8 mmol/L. “Millimole per liter” (mmol/L) is the international unit for measuring blood sugar. It indicates the concentration of a certain substance per liter. If type 1 diabetes is left untreated, people’s blood sugar levels can get very high, even exceeding 27.8 mmol/L (500 mg/dL). Such high levels are rather uncommon for type 2 diabetes. Blood sugar concentrations below 3.3 mmol/L (60 mg/dL) are considered to be too low. As you can see in the illustration below, there are no clear-cut borders between the normal range of blood sugar and high and low blood sugar.

Hyperglycemia In Diabetes

Hyperglycemia In Diabetes

Print Overview High blood sugar (hyperglycemia) affects people who have diabetes. Several factors can contribute to hyperglycemia in people with diabetes, including food and physical activity choices, illness, nondiabetes medications, or skipping or not taking enough glucose-lowering medication. It's important to treat hyperglycemia, because if left untreated, hyperglycemia can become severe and lead to serious complications requiring emergency care, such as a diabetic coma. In the long term, persistent hyperglycemia, even if not severe, can lead to complications affecting your eyes, kidneys, nerves and heart. Symptoms Hyperglycemia doesn't cause symptoms until glucose values are significantly elevated — above 200 milligrams per deciliter (mg/dL), or 11 millimoles per liter (mmol/L). Symptoms of hyperglycemia develop slowly over several days or weeks. The longer blood sugar levels stay high, the more serious the symptoms become. However, some people who've had type 2 diabetes for a long time may not show any symptoms despite elevated blood sugars. Early signs and symptoms Recognizing early symptoms of hyperglycemia can help you treat the condition promptly. Watch for: Frequent urination Increased thirst Blurred vision Fatigue Headache Later signs and symptoms If hyperglycemia goes untreated, it can cause toxic acids (ketones) to build up in your blood and urine (ketoacidosis). Signs and symptoms include: Fruity-smelling breath Nausea and vomiting Shortness of breath Dry mouth Weakness Confusion Coma Abdominal pain When to see a doctor Call 911 or emergency medical assistance if: You're sick and can't keep any food or fluids down, and Your blood glucose levels are persistently above 240 mg/dL (13 mmol/L) and you have ketones in your urine Make an appointment with your Continue reading >>

Diabetic Coma

Diabetic Coma

Print Overview A diabetic coma is a life-threatening diabetes complication that causes unconsciousness. If you have diabetes, dangerously high blood sugar (hyperglycemia) or dangerously low blood sugar (hypoglycemia) can lead to a diabetic coma. If you lapse into a diabetic coma, you're alive — but you can't awaken or respond purposefully to sights, sounds or other types of stimulation. Left untreated, a diabetic coma can be fatal. The prospect of a diabetic coma is scary, but fortunately you can take steps to help prevent it. Start by following your diabetes treatment plan. Symptoms Before developing a diabetic coma, you'll usually experience signs and symptoms of high blood sugar or low blood sugar. High blood sugar (hyperglycemia) If your blood sugar level is too high, you may experience: Increased thirst Frequent urination Fatigue Nausea and vomiting Shortness of breath Stomach pain Fruity breath odor A very dry mouth A rapid heartbeat Low blood sugar (hypoglycemia) Signs and symptoms of a low blood sugar level may include: Shakiness or nervousness Anxiety Fatigue Weakness Sweating Hunger Nausea Dizziness or light-headedness Difficulty speaking Confusion Some people, especially those who've had diabetes for a long time, develop a condition known as hypoglycemia unawareness and won't have the warning signs that signal a drop in blood sugar. If you experience any symptoms of high or low blood sugar, test your blood sugar and follow your diabetes treatment plan based on the test results. If you don't start to feel better quickly, or you start to feel worse, call for emergency help. When to see a doctor A diabetic coma is a medical emergency. If you feel extreme high or low blood sugar signs or symptoms and think you might pass out, call 911 or your local emergency nu Continue reading >>

Signs & Symptoms Hypoglycemia & Hyperglycemia

Signs & Symptoms Hypoglycemia & Hyperglycemia

More than 23 million children and adults in the United States have diabetes, and each year 1.6 million people receive a new diagnosis of this disease, according to the American Diabetes Association. People with diabetes must carefully manage their blood sugar, or blood glucose, levels with diet, physical activity and medication to prevent diabetes complications and avoid hypoglycemia and hyperglycemia. Video of the Day When blood sugar levels drop below normal levels, a person may experience symptoms of hypoglycemia, such as nervousness, shakiness and hunger. He may sweat and feel dizzy, lightheaded and confused. Sleepiness, anxiety, confusion and difficulty talking are also signs that a person has hypoglycemia. A person who has hypoglycemia while sleeping may sweat profusely during sleep, experience nightmares or wake feeling tired and irritable. If hypoglycemia isn’t treated, the condition can worsen, causing more-severe symptoms such as fainting, confusion, clumsiness, seizures, coma and even death. According to the National Diabetes Information Clearinghouse, most cases of hypoglycemia are mild, and consuming food or drink rich in carbohydrates helps bring blood sugar levels back to normal. People with diabetes may need to take glucose tablets to raise their blood sugar levels quickly and avoid hypoglycemia's complications. Hyperglycemia, or high blood sugar levels, occur when the body lacks insulin or cannot use insulin properly. High levels of sugar in the urine indicate hyperglycemia; frequently feeling thirsty and having to urinate often are also indicators of high blood sugar levels. According to the American Diabetes Association, checking blood sugar levels often can help alert you to hyperglycemia before you feel symptoms. In many cases, reducing food intak Continue reading >>

Diabetes And Hyperglycemia

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 >>

Diabetic Reaction

Diabetic Reaction

A A A There are two main forms of diabetes: Type 1 diabetes: Absent or low insulin levels prevent cells from taking up and using sugar for energy, thus requiring insulin injections Type 2 diabetes: Cellular resistance to insulin reduces glucose uptake, often requiring medication to improve the sensitivity of cells to insulin Low blood sugar (hypoglycemia) is the most common form of diabetic reaction. A low blood sugar reaction is caused by increased exertion or increased demand for glucose. The body may "run out" of stored glucose more quickly, thus bringing on a hypoglycemic attack. Persistent intake of excessive alcohol may cause this reaction, because alcohol decreases glucose stores in the liver. High blood sugar (hyperglycemia) is a common problem for people with diabetes. High blood sugar can be brought on by infections or other significant stresses that cause the body to decrease cell uptake of glucose. A decrease in cell uptake of glucose leads to high blood sugar levels as well as the alternative use of fats by starving cells for energy. Fat breakdown increases the acidity of the blood and worsens symptoms of high blood sugar. Symptoms of diabetic reaction depends on the type of reaction. rapid onset of cool, pale, moist, and clammy skin; dizziness; headache; rapid pulse; and shallow breathing. If untreated, symptoms may progress to confusion, nonsensical behavior, coma, and death. Symptoms occur gradually over several days. The person with high blood sugar develops increasing thirst and urination due to large amounts of unused glucose being lost in the urine. Skin feels warm and dry; respirations may be shallow; pulse is rapid and weak, and breath may have a sweet odor (due to ketoacidosis from fat breakdown). The person with high blood sugar may become confus Continue reading >>

Nondiabetic Hypoglycemia

Nondiabetic Hypoglycemia

What is non-diabetic hypoglycemia? Hypoglycemia is the condition when your blood glucose (sugar) levels are too low. It happens to people with diabetes when they have a mismatch of medicine, food, and/or exercise. Non-diabetic hypoglycemia, a rare condition, is low blood glucose in people who do not have diabetes. There are two kinds of non-diabetic hypoglycemia: Reactive hypoglycemia, which happens within a few hours of eating a meal Fasting hypoglycemia, which may be related to a disease Glucose is the main source of energy for your body and brain. It comes from what we eat and drink. Insulin, a hormone, helps keep blood glucose at normal levels so your body can work properly. Insulin’s job is to help glucose enter your cells where it’s used for energy. If your glucose level is too low, you might not feel well. What causes non-diabetic hypoglycemia? The two kinds of non-diabetic hypoglycemia have different causes. Researchers are still studying the causes of reactive hypoglycemia. They know, however, that it comes from having too much insulin in the blood, leading to low blood glucose levels. Types of nondiabetic hypoglycemia Reactive hypoglycemia Having pre-diabetes or being at risk for diabetes, which can lead to trouble making the right amount of insulin Stomach surgery, which can make food pass too quickly into your small intestine Rare enzyme deficiencies that make it hard for your body to break down food Fasting hypoglycemia Medicines, such as salicylates (such as aspirin), sulfa drugs (an antibiotic), pentamidine (to treat a serious kind of pneumonia), quinine (to treat malaria) Alcohol, especially with binge drinking Serious illnesses, such as those affecting the liver, heart, or kidneys Low levels of certain hormones, such as cortisol, growth hormone, glu Continue reading >>

What Is The Difference Between Hypoglycemia And Hyperglycemia?

What Is The Difference Between Hypoglycemia And Hyperglycemia?

Hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) can both occur in patients who have diabetes. Diabetes occurs when the body does not produce enough insulin (known as ‘Type 1 Diabetes’) or the cells in the body stop responding to insulin (known as ‘Type 2 Diabetes’). So what’s the difference between hypoglycemia and hyperglycemia? And how can a first aider spot the difference? Read on to find out how! Hypoglycemia Hypoglycemia occurs when insulin is in excess of that needed to balance the patient’s food intake and energy expenditure. If untreated it will lead to unconsciousness and if prolonged, irreversible damage can occur. Signs and symptoms can be found for hypoglycemia and hyperglycemia in the table below. Hypoglycemic patients may appear drunk although alcohol may also induce hypoglycemia. You should never discount the possibility that a patient who appears to be drunk may in fact be hypoglycemic. Most patients under the influence of alcohol will have their blood glucose levels recorded at hospital to ensure that they are not hypoglycemic. Hyperglycemia Hyperglycemia is often the presenting feature of diabetes. Patients who have not been diagnosed as diabetics will often go to their doctor complaining of excessive hunger, thirst and urination. On testing their blood glucose levels they are often found to be greater than 20 mmol/l (normal non-diabetics range is 3.0-5.6 mmol/l). Diabetic patients who are hyperglycemic have often been ill for some hours or days and have since deteriorated − most calls for assistance are made when the patient falls unconscious Want to learn more?
