Impaired Glucose Tolerance (IGT) is a pre-diabetic state of dysglycemia, that is associated with insulin resistance and increased risk of cardiovascular pathology. IGT may precede type 2 diabetes mellitus by many years. IGT is also a risk factor for mortality.^[1] The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify diseases and a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances and external causes of injury or disease. ...

Criteria

According to the criteria of the World Health Organization and the American Diabetes Association, impaired glucose tolerance is defined as^[2][3]: In medicine, blood sugar is a term used to refer to levels of glucose in the blood. ... Fructosamine, also known as Glycated Serum Protein (GSP) or Glycated Albumin, is used primarily to identify the plasma glucose concentration over time and so assess diabetic control . ... A glucose tolerance test in medical practice is the administration of glucose to determine how quickly it is cleared from the blood. ... Glycosylated (or glycated) hemoglobin (hemoglobin A1c, Hb1c , HbA1c or HgA1c) is a form of hemoglobin used primarily to identify the plasma glucose concentration over time. ...

• 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. A patient is said to be under the condition of IGT when he/she has an intermediately raised glucose level after 2 hours, but less than would qualify for type 2 diabetes mellitus. The fasting glucose may be either normal or mildly elevated.

From 10 to 15 percent of adults in the United States have one of these conditions.^[4] Oral glucose tolerance test (OGTT) is a medical test that is performed to diagnose (or exclude) diabetes. ... Glucose (Glc), a monosaccharide (or simple sugar), is an important carbohydrate in biology. ... Fasting is primarily the act of willingly abstaining from some or all food, drink, or both, for a period of time. ...

The risk of progression to diabetes and development of cardiovascular disease is greater than for Impaired fasting glycaemia.^{[citation needed]} Diabetes mellitus type 2 or Type 2 Diabetes (formerly called non-insulin-dependent diabetes (NIDDM), obesity-related diabetes, or adult-onset diabetes) is a metabolic disorder that is primarily characterized by insulin resistance, relative insulin deficiency, and hyperglycemia. ... Impaired fasting glycaemia (IFG) is a pre-diabetic state of dysglycemia, associated with insulin resistance and increased risk cardiovascular pathology, although of lesser risk than Impaired glucose tolerance (IGT). ...

Although some drugs can delay the onset of diabetes, lifestyle modifications play a greater role in the prevention of the disease.^[4] Patients identified as having an IGT should exercise regularly and Limit sugar intake. This article is about sugar as food and as an important and widely-traded commodity. ...

Carnitine has been shown to improve glucose uptake, regulation, and oxidation, though temporarily (i.e. only when levels are sustained in the blood). This article or section contains information that has not been verified and thus might not be reliable. ...
