Impaired glucose tolerance (IGT) is diagnosed with an oral glucose tolerance test. According to the criteria of the World Health Organization and the American Diabetes Association, impaired glucose tolerance is defined as: [13] [14] two-hour glucose levels of 140 to 199 mg per dL (7.8 to 11.0 mmol/L) on the 75-g oral glucose tolerance test.
Reactive hypoglycemia, postprandial hypoglycemia, or sugar crash is a term describing recurrent episodes of symptomatic hypoglycemia occurring within four hours [ 1] after a high carbohydrate meal in people with and without diabetes. [ 2] The term is not necessarily a diagnosis since it requires an evaluation to determine the cause of the ...
The glucose tolerance test was first described in 1923 by Jerome W. Conn. [4]The test was based on the previous work in 1913 by A. T. B. Jacobson in determining that carbohydrate ingestion results in blood glucose fluctuations, [5] and the premise (named the Staub-Traugott Phenomenon after its first observers H. Staub in 1921 and K. Traugott in 1922) that a normal patient fed glucose will ...
People with plasma glucose at or above 7.8 mmol/L (140 mg/dL), but not over 11.1 mmol/L (200 mg/dL), two hours after a 75 gram oral glucose load are considered to have impaired glucose tolerance. Of these two prediabetic states, the latter in particular is a major risk factor for progression to full-blown diabetes mellitus, as well as ...
Diabetes management. The term diabetes includes several different metabolic disorders that all, if left untreated, result in abnormally high concentrations of a sugar called glucose in the blood. Diabetes mellitus type 1 results when the pancreas no longer produces significant amounts of the hormone insulin, usually owing to the autoimmune ...
Diabetic retinopathy (also known as diabetic eye disease ), is a medical condition in which damage occurs to the retina due to diabetes. It is a leading cause of blindness in developed countries. Diabetic retinopathy affects up to 80 percent of those who have had both type 1 and type 2 diabetes for 20 years or more.
A level below 5.6 mmol/L (100 mg/dL) 10–16 hours without eating is normal. 5.6–6 mmol/L (100–109 mg/dL) may indicate prediabetes and oral glucose tolerance test (OGTT) should be done for high-risk individuals (old people, those with high blood pressure etc.). 6.1–6.9 mmol/L (110–125 mg/dL) means OGTT should be done even if other ...
Four generations of blood glucose meter, c. 1991–2005. Sample sizes vary from 30 to 0.3 μl. Test times vary from 5 seconds to 2 minutes (modern meters typically require less than 15 seconds). A blood glucose meter is an electronic device for measuring the blood glucose level. A relatively small drop of blood is placed on a disposable test ...
