What Are Impaired Blood Glucose Levels?

Impaired Fasting Glucose

Impaired Fasting Glucose

Barbara J. Ehrmann, in A Comprehensive Guide to Geriatric Rehabilitation (Third Edition) , 2014 An elevated fasting glucose is one of several risk factors that is known to increase an individuals risk of developing heart disease, stroke and diabetes. These risk factors, grouped together, are called the metabolic syndrome. Other characteristics include obesity, particularly abdominal fat, hyperlipidemia and hypertension. The criteria for metabolic syndrome are met by having any three of the following risk factors, as recently defined by the American Heart Association and International Diabetes Federation: (i) an elevated waist circumference (abdominal obesity); (ii) an elevated triglyceride level of 150mg/dl or greater; (iii) a reduced high-density lipoprotein (HDL good cholesterol) level of less than 40mg/dl for men and less than 50mg/dl for women; (iv) an elevated blood pressure of 130/85mmHg or higher; and (v) an elevated fasting glucose of 100mg/dl or higher (Alberti et al., 2009). Fifty-two percent of males and 54% of females in the US over the age of 60 met the criteria for metabolic syndrome for the years 20032006 (Ervin, 2009). Karen Z. Walker, Kerin ODea, in Nutritional and Therapeutic Interventions for Diabetes and Metabolic Syndrome , 2012 Individuals with impaired fasting glucose or impaired glucose tolerance are at high risk of progression to type 2 diabetes. This disease can be delayed or prevented through changes to dietary pattern and increased physical activity. Large prospective studies following high-risk individuals for a period of 2.56 years indicate that lifestyle change may reduce the incidence of type 2 diabetes by 2868%. Moreover, diabetes incidence rates continue to be depressed many years after completion of the supervised phase of a lifestyle Continue reading >>

Impaired Fasting Glycaemia

Impaired Fasting Glycaemia

This factsheet is for people who have impaired fasting glycaemia, or who would like information about it. Impaired fasting glycaemia (IFG) is sometimes called pre-diabetes. This is when blood glucose levels in the body are raised, but are not high enough to mean that the person has diabetes. IFG means that the body isn't able to use glucose as efficiently as it should. Impaired fasting glycaemia (IFG) means that your body isn't able to regulate glucose as efficiently as it should. Glucose is a simple form of sugar found in foods and sugary drinks it's absorbed as a natural part of digestion. One function of your blood is to carry glucose around your body. When glucose reaches body tissues, such as muscle cells, it's absorbed and converted into energy. The glucose concentration in your blood is automatically regulated by a hormone called insulin. The amount of glucose in your blood changes throughout the day. Its higher and lower depending on what youre eating and drinking. Blood glucose levels can be measured in a laboratory by testing a blood sample. This is usually done when you have not eaten for eight hours and is called a fasting blood glucose test. Its estimated that seven million people in the UK have IFG. IFG has no symptoms and can often go undiagnosed for years. Although there are no symptoms, many people diagnosed with IFG are overweight. Nine out of 10 people with IFG have high blood pressure, raised cholesterol levels or a family history of the condition. IFG can increase your risk of type 2 diabetes. Many people with type 2 diabetes have no symptoms, but if you do have symptoms they might include: If you have any of these symptoms, you should talk to your GP. Complications of impaired fasting glycaemia IFG can lead to the development of type 2 diabetes. P Continue reading >>

Pre-diabetes Impaired Glucose Tolerance

Pre-diabetes Impaired Glucose Tolerance

In pre-diabetes (impaired glucose tolerance), your blood sugar (glucose) is raised beyond the normal range. Whilst this raised glucose level is not so high that you have diabetes, you are at increased risk of developing diabetes when you have pre-diabetes. You are also at increased risk of developing conditions such as heart disease, peripheral arterial disease and stroke (cardiovascular diseases). If pre-diabetes is treated, it can help to prevent the development of diabetes and cardiovascular disease. The most effective treatment is lifestyle changes, including eating a healthy balanced diet, losing weight if you are overweight, and doing regular physical activity. What is pre-diabetes?

Diabetes mellitus (DM) and its associated disease outcomes are a growing concern worldwide. The current global prevalence of DM for all ages has been estimated at 2.8 percent and is predicted to reach 4.4 percent by 2030. 1 There is intense interest in identifying and treating risk factors that may prevent the onset of this disease and minimize morbidity. Impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) are the intermediate metabolic states between normal and diabetic glucose homeostasis. These conditions are thought to be the precursors of DM, but the progression to overt disease is not straight-forward. The risk for both macrovascular and microvascular complications increases across the distribution of blood glucose concentrations well below the overt DM, and the risk is more strongly associated with post-challenge hyperglycemia than fasting glucose levels. However, it is unclear whether this glucose effect is independent of classical risk factors, such as blood pressure and lipids, or occurs due to abnormalities of other metabolites, such as free fatty acids. The goal of this systematic review is to evaluate the state of the evidence in the areas of the diagnosis Continue reading >>

Managing Impaired Glucose Tolerance In Primary Care

Managing Impaired Glucose Tolerance In Primary Care

Managing Impaired Glucose Tolerance in Primary Care This article is for Medical Professionals Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use. You may find the Pre-diabetes (Impaired Glucose Tolerance) article more useful, or one of our other health articles . Managing Impaired Glucose Tolerance in Primary Care Impaired glucose tolerance is defined as a fasting plasma glucose concentration of less than 7.0 mmol/L with a two-hour oral glucose tolerance test value of 7.8 to 11.1 mmol/L[ 1 ]. Impaired fasting glycaemia is defined as a fasting glucose of 6.1 to 6.9 mmol/L. The World Health Organization (WHO) has recommended that people with an HbA1c of 4247 mmol/mol (6.0-6.5%) are at high risk of diabetes[ 2 ]. Impaired glucose tolerance, typically characterised by hyperglycaemia and insulin resistance, is considered to be a stage in the development of type 2 diabetes mellitus and a risk factor for cardiovascular disease[ 3 ]. Therefore, impaired glucose tolerance is often referred to as pre-diabetes. The prevalence of impaired glucose tolerance increases linearly from about 15% in middle age to 35-40% in the elderly[ 4 ]. Evidence suggests that a 1 kg/m2 increase in body mass index (BMI) increases the risk of developing new-onset type 2 diabetes by 8.4%. The risk of impaired fasting glucose rises by 9.5%[ 2 ]. Other investigations similar to those for people with type 2 diabetes may be indicated. Several cardiovascular findings are more prevalent, including hypertension , angina and medical history of atherosclerosis and stroke . Hyperlipidaemia is also often associated. Intervention can favourably influence the clinical course of impaired glucose to Continue reading >>

Prediabetes

Prediabetes

What Is Prediabetes? Prediabetes is a “pre-diagnosis” of diabetes—you can think of it as a warning sign. It’s when your blood glucose level (blood sugar level) is higher than normal, but it’s not high enough to be considered diabetes. Prediabetes is an indication that you could develop type 2 diabetes if you don’t make some lifestyle changes. But here's the good news: . Eating healthy food, losing weight and staying at a healthy weight, and being physically active can help you bring your blood glucose level back into the normal range. Diabetes develops very gradually, so when you’re in the prediabetes stage—when your blood glucose level is higher than it should be—you may not have any symptoms at all. You may, however, notice that: you’re hungrier than normal you’re losing weight, despite eating more you’re thirstier than normal you have to go to the bathroom more frequently you’re more tired than usual All of those are typical symptoms associated with diabetes, so if you’re in the early stages of diabetes, you may notice them. Prediabetes develops when your body begins to have trouble using the hormone insulin. Insulin is necessary to transport glucose—what your body uses for energy—into the cells via the bloodstream. In pre-diabetes, your body either doesn’t make enough insulin or it doesn’t use it well (that’s called insulin resistance). If you don’t have enough insulin or if you’re insulin resistant, you can build up too much glucose in your blood, leading to a higher-than-normal blood glucose level and perhaps prediabetes. Researchers aren’t sure what exactly causes the insulin process to go awry in some people. There are several risk factors, though, that make it more likely that you’ll develop pre-diabetes. These are Continue reading >>

Impaired Fasting Glycaemia

Impaired Fasting Glycaemia

This factsheet is for people whose blood test has shown a marginally high fasting glucose (blood sugar) level or who would like information about impaired fasting glycaemia. Impaired fasting glycaemia (IFG) means that your body isn't able to regulate glucose as efficiently as it should. About impaired fasting glycaemia Complications Causes Diagnosis Treatment Further information Sources Related topics About impaired fasting glycaemia Glucose enters the blood from your intestines, where it's absorbed from food and drinks as a natural part of digestion. When glucose reaches your body tissues, such as muscle, it's made available to cells where it is needed for energy by the hormone insulin. Insulin regulates the level of glucose in the blood so that it doesn't go too high or too low. What is the normal range for blood glucose? Blood glucose concentrations change throughout the day. They are typically higher after eating and lower during fasting. A fasting blood glucose level lower than 6mmol/l is normal. A fasting blood glucose of 7mmol/l or higher may indicate diabetes. Diabetes is a long-term condition where the body is not able to control the amount of glucose in the blood. If your fasting blood glucose level is below 7mmol/l but above 6mmol/l you may have IFG or impaired glucose tolerance (IGT). IFG and IGT are not diabetes but suggest that your body is not converting glucose to energy as efficiently as it should. For the range of blood glucose concentrations associated with IFG, see Diagnosis. Complications Some people with IFG will go on to develop type 2 diabetes. Others may develop diabetes only if they don't take steps to reduce the chances of this happening (see Self-help). Diabetes is 10 to 20 times more likely in those with IGT or IFG. Since IFG can be an early Continue reading >>

Medical Definition Of Impaired Glucose Tolerance

Medical Definition Of Impaired Glucose Tolerance

Amputations. INVOKANA® may increase your risk of lower-limb amputations. Amputations mainly involve removal of the toe or part of the foot; however, amputations involving the leg, below and above the knee, have also occurred. Some people had more than one amputation, some on both sides of the body. Youmay be at a higher risk of lower-limb amputation if you: have a history of amputation, have heart disease or are at risk for heart disease, have had blocked or narrowed blood vessels (usually in leg), have damage to the nerves (neuropathy)in the leg, or have had diabetic foot ulcers or sores. Call your doctor right away if you have new pain or tenderness, any sores, ulcers, or infections in your leg or foot. Your doctor may decide to stop your INVOKANA®. Talk to your doctor about proper foot care Dehydration. INVOKANA® can cause some people to become dehydrated (the loss of too much body water), which may cause you to feel dizzy, faint, lightheaded, or weak, especially when you stand up (orthostatic hypotension). Youmay be at higher risk of dehydration if you have low blood pressure, take medicines to lower your blood pressure (including diuretics [water pills]), are on a low sodium (salt) diet, have kidney problems, or are 65 years of age orolder Yeast infection of the penis (balanitis or balanoposthitis).Men who take INVOKANA® may get a yeast infection of the skin around the penis. Symptoms include: redness, itching, or swelling of the penis; rash of the penis; foul-smelling discharge from the penis;or pain in the skin around penis Before you take INVOKANA®, tell your doctor if you have a history of amputation; heart disease or are at risk for heart disease; blocked or narrowed blood vessels (usually in leg); damage to the nerves (neuropathy) of your leg; diabetic f Continue reading >>

Pre-diabetes

Pre-diabetes

Pre-diabetes describes a condition in which blood glucose levels are higher than normal, although not high enough to be diagnosed with type 2 diabetes. Pre-diabetes has no signs or symptoms. People with pre-diabetes have a higher risk of developing type 2 diabetes and cardiovascular (heart and circulation) disease. Two million Australians have pre-diabetes and are at high-risk of developing type 2 diabetes. Without sustained lifestyle changes, including healthy eating, increased activity and losing weight, approximately one in three people with pre-diabetes will go on to develop type 2 diabetes. There are two pre-diabetes conditions: Impaired glucose tolerance (IGT) is where blood glucose levels are higher than normal but not high enough to be classified as diabetes. Impaired fasting glucose (IFG) is where blood glucose levels are escalated in the fasting state but not high enough to be classified as diabetes. It is possible to have both Impaired Fasting Glucose (IFG) and Impaired Glucose Tolerance (IGT) Risk factors for pre-diabetes are similar to those for type 2 diabetes which are: Being overweight – especially those who have excess weight around the waistline (ie: more than 94cm for men and more than 80cm for women). Being physically inactive. Having high triglycerides and low HDL-C (good cholesterol) and/or high total cholesterol. Having high blood pressure. Having a family history of type 2 diabetes and/or heart disease. Women with Polycystic Ovarian Syndrome*. Women who have had diabetes in pregnancy (gestational diabetes) or given birth to a big baby (more than 4.5kgs). Those from Aboriginal and Torres Strait Islander background. Those from certain ethnic backgrounds such as the Pacific Islands, Asia and the Indian sub-continent. For more information refer to Continue reading >>

Diet For Impaired Fasting Glucose

Diet For Impaired Fasting Glucose

M. Gideon Hoyle is a writer living outside of Houston. Previously, he produced brochures and a wide variety of other materials for a nonprofit educational foundation. He now specializes in topics related to health, exercise and nutrition, publishing for various websites. Fruits and vegetables are important parts of an impaired fasting glucose diet. A fasting glucose test is a procedure designed to measure your blood levels of glucose after you go without eating for at least eight hours. Moderately elevated results from this test indicate the presence of a condition called impaired fasting glucose, which greatly increases your risk for developing diabetes. You can help reverse an impaired glucose finding by making certain changes to your diet. If your doctor suspects that you have dangerously high blood glucose levels, he can order a fasting glucose test to help definitively diagnose your condition, according to the National Diabetes Information Clearinghouse. Typically, you will fast overnight and undergo testing during the morning. If a fasting glucose test reveals levels of glucose between 100 and 125mg per deciliter of blood, or mg/dL, you have impaired fasting glucose. The condition is also commonly known as pre-diabetes. You can help prevent pre-diabetes from progressing to full-blown diabetes by altering several aspects of your everyday lifestyle, the American Academy of Family Physicians reports at FamilyDoctor.org. With respect to your diet, recommended changes to help lower your glucose levels include substituting whole grains for processed products that contain white flour; increasing your intake of vegetables, fruits, poultry, fish and beans; and restricting your intake of sugar and other sweeteners such as molasses and honey. In addition to these general gu Continue reading >>

Impaired Fasting Glycaemia (glucose In The Blood)

Impaired Fasting Glycaemia (glucose In The Blood)

Impaired Fasting Glycaemia (Glucose in the blood) Impaired fasting glycaemia (IFG) is sometimes called pre-diabetes. This is when blood glucose levels in the body are raised, but are not high enough to mean that the person has diabetes. IFG means that the body isnt able to use glucose as efficiently as it should. This is because a layer of fat around the cells of the body, prevents insulin doing its job and taking the glucose into the cells of the body where its needed for energy. This situation is reversible by losing weight and hence the fat around the cells disappears. If you dont lose weight however, is it unlikely that you wont eventually develop Type 2 Diabetes. IFG has no symptoms and can often go undiagnosed for years. Although there are no symptoms, many people diagnosed with IFG are overweight. Nine out of 10 people with IFG have high blood pressure, raised cholesterol levels or a family history of the condition. IFG can lead to the development of type 2 diabetes. People with IFG are five to 15 times more likely to develop type 2 diabetes than people with normal glucose levels. However, this isnt inevitable. You can take steps to reduce the chances of this happening. People with IFG also have a slightly increased risk of heart disease and stroke. If your fasting blood glucose level is between 3.6mmol/l and 6mmol/l, this means that your blood glucose level is normal. If your fasting blood glucose level is 7mmol/l or higher, this is likely to mean that you have diabetes. Diabetes is a long-term condition where the body is not able to control the amount of glucose in the blood. If your fasting blood glucose level is between 6.1mmol/l and 6.9mmols/l, you may have IFG. IFG doesnt need medical treatment, but its important to try and lower your blood glucose levels Continue reading >>

Diagnosing Impaired Glucose Tolerance (igt)

Diagnosing Impaired Glucose Tolerance (igt)

People with IGT have blood glucose levels that are higher than normal but not high enough to say they have diabetes. This condition is diagnosed using the oral glucose tolerance test (OGTT). After a fast of 8 to12 hours, a person's blood glucose is measured before and 2 hours after drinking a glucose-containing solution. In normal glucose tolerance, blood glucose rises no higher than 140 mg/dl 2 hours after the drink. In impaired glucose tolerance (IGT), the 2-hour blood glucose is between 140 and 199 mg/dl. If the 2-hour blood glucose rises to 200 mg/dl or above, a person has diabetes. How does the fasting blood glucose test differ from the oral glucose tolerance test? In the fasting blood glucose test, a person's blood glucose is measured after a fast of 8 to 12 hours: A person with normal blood glucose has a blood glucose level below 100. A person with impaired fasting glucose has a blood glucose level between 100 and 125 mg/dl. If the fasting blood glucose level rises to126 mg/dl or above, a person has diabetes. The OGTT includes measures of blood glucose levels after a fast and after a glucose challenge. In 1997, an American Diabetes Association (ADA) expert panel recommended that doctors use the fasting blood glucose test to screen their patients for diabetes because the test is easier and less costly than the OGTT. Though the fasting glucose test detects most diabetes cases, the OGTT is more sensitive in identifying people with blood glucose problems that may first appear only after a glucose challenge. For a person with IGT, what is the risk of developing type 2 diabetes? As few as 1 to as many as 10 of every 100 persons with IGT will develop diabetes per year. The risk of getting diabetes rises as people become more overweight and more sedentary, have a stronge Continue reading >>

Impaired Glucose Tolerance And Impaired Fasting Glucose

Impaired Glucose Tolerance And Impaired Fasting Glucose

Impaired glucose tolerance and impaired fasting glucose form an intermediate stage in the natural history of diabetes mellitus. From 10 to 15 percent of adults in the United States have one of these conditions. Impaired glucose tolerance is defined as two-hour glucose levels of 140 to 199 mg per dL (7.8 to 11.0 mmol) on the 75-g oral glucose tolerance test, and impaired fasting glucose is defined as glucose levels of 100 to 125 mg per dL (5.6 to 6.9 mmol per L) in fasting patients. These glucose levels are above normal but below the level that is diagnostic for diabetes. Patients with impaired glucose tolerance or impaired fasting glucose have a significant risk of developing diabetes and thus are an important target group for primary prevention. Risk factors for diabetes include family history of diabetes, body mass index greater than 25 kg per m2, sedentary lifestyle, hypertension, dyslipidemia, history of gestational diabetes or large-for-gestational-age infant, and polycystic ovary syndrome. Blacks, Latin Americans, Native Americans, and Asian-Pacific Islanders also are at increased risk for diabetes. Patients at higher risk should be screened with a fasting plasma glucose level. When the diagnosis of impaired glucose tolerance or impaired fasting glucose is made, physicians should counsel patients to lose 5 to 7 percent of their body weight and engage in moderate physical activity for at least 150 minutes per week. Drug therapy with metformin or acarbose has been shown to delay or prevent the onset of diabetes. However, medications are not as effective as lifestyle changes, and it is not known if treatment with these drugs is cost effective in the management of impaired glucose tolerance.

Impaired Fasting Glycemia

Impaired Fasting Glycemia

A person with impaired fasting glycemia isn't able to process glucose as efficiently as they should be able to Impaired fasting glycemia (IFG) may also be known as pre-diabetes or metabolic syndrome. Impaired fasting glycemia occurs when blood glucose levels in the body are elevated during periods of fasting , but not enough to prompt a diagnosis of diabetes. Effectively, a person with impaired fasting glycemia isnt able to process glucose as efficiently as they should be able to. What are the health implications of impaired fasting glycemia? People with impaired fasting glycemia face a greater risk of developing type 2 diabetes, despite having less of a risk than those with impaired glucose tolerance. The risk of developing cardiovascular disease is also lower than for people with impaired glucose tolerance . What does impaired fasting glycemia mean? Impaired fasting glycemia (IFG) means that the body cannot regulate glucose as efficiently as it should be able to. Glucose is usually carried around the body where it is absorbed and made into energy. Insulin regulates the concentration of glucose in the blood. IFG occurs when this process isnt functioning as effectively as it could, and effects millions of people in the UK. What are the symptoms of impaired fasting glycemia? Unfortunately, IFG may exhibit very little in the way of symptoms, meaning diagnosis often takes a long time. Many people diagnosed with IFG are overweight, have high blood pressure, increased cholesterol levels or a family history of IFG. So how do I know if my IFG becomes type 2 diabetes? IFG increases type 2 diabetes risk, so go straight to your doctor or healthcare professional if you feel unnaturally thirsty, pass more urine than usual, have recurrent infections, have blurred vision, or if your Continue reading >>

Impaired Fasting Glucose

Impaired Fasting Glucose

Impaired fasting glucose, or Impaired Fasting Glycemia (IFG) is a type of prediabetes, in which a person's blood sugar levels during fasting are consistently above the normal range, but below the diagnostic cut-off for a formal diagnosis of diabetes mellitus.[1] Together with impaired glucose tolerance, it is a sign of insulin resistance. In this manner, it is also one of the conditions associated with Metabolic Syndrome. Those with impaired fasting glucose are at an increased risk of vascular complications of diabetes, though to a lesser extent. The risks are cumulative, with both higher blood glucose levels, and the total amount of time it spends elevated, increasing the overall complication rate. IFG can eventually progress to type 2 diabetes mellitus without intervention, which typically involves lifestyle modification. Those with impaired fasting glucose have a 1.5 fold increased risk of developing clinical diabetes within 10 years, when compared to the general population. Some studies suggest that without lifestyle changes, IFG will progress to clinically diagnosable diabetes in just under 3 years, on average.[2] Impaired fasting glucose is often, though not always, associated with impaired glucose tolerance, though it may occur in isolation, with such persons having a normal response to a glucose tolerance test. Signs and Symptoms[edit] Impaired fasting glucose is often without any signs or symptoms, other than higher than normal glucose levels being detected in an individual's fasting blood sample. There may be signs and symptoms associated with elevated blood glucose, though these are likely to be minor, with significant symptoms suggestive of complete progression to type 2 diabetes. Such symptoms include:[3] Increased thirst Increased urination, especially wak Continue reading >>
