Reactive hypoglycemia (RH) is the condition of postprandially hypoglycemia occurring 2-5 hours after food intake. RH is clinically seen in three different forms as follows: idiopathic RH (at 180 min), alimentary (within 120 min), and late RH (at ...

IGT is defined on the basis of an abnormal oral glucose tolerance test (OGTT). Persons without diabetes but with an OGTT 2-hour value of 140-199 mg/dl are considered to have IGT. Recent national and international randomized controlled trials have shown that diabetes can be delayed or prevented among persons with IGT.

2023年4月23日 · A glucose tolerance test (GTT) is a procedure that determines whether a patient can use and store glucose normally. [1] The test is usually used to test for diabetes mellitus, insulin resistance, impaired pancreatic beta cell function, and sometimes reactive hypoglycemia or acromegaly, or rarer disorders of carbohydrate metabolism. [2]

The diagnosis was based upon reproduction of the patient's hypoglycemia symptoms in association with a blood glucose value of <50 mg/dL (2.8 mmol/L) after an oral glucose tolerance test (OGTT) [7].

2023年2月28日 · However, if any parts of the system do not work, glucose can build up fast and lead to high blood sugar levels (hyperglycemia) and diabetes. Lack of insulin or insulin resistance causes higher than normal levels of glucose in the blood. The oral glucose tolerance test is can spot imbalances in this process that other tests can miss.

Despite this, there has been a steadfast global consensus of the 2-h PG for defining dysglycemic states during the OGTT. This article reviews the history of the OGTT and recent advances in its application, including the glucose challenge test and mathematical modeling for determining the shape of the glucose curve.

2021年11月18日 · Hypoglycemia during OGTT was defined as at least one glucose value below 60 mg/dl. Maternal characteristics and perinatal outcomes were compared between three groups: Hypoglycemia on OGTT, Normal OGTT and Abnormal OGTT. Univariate followed by multivariate analyses were used to control for confounders.

1988年3月1日 · From a practical standpoint, however, it has limited applicability. The test should never be done to evaluate reactive hypoglycemia. It can be used in the patient whose fasting plasma glucose level is less than 140 mg/dl but who manifests symptoms compatible with complications of diabetes.

2023年12月19日 · 口服葡萄糖耐量试验（oral glucose tolerance test, OGTT）是一种葡萄糖负荷试验，用以了解胰岛β细胞功能和机体对血糖的调节能力，是临床常用的用于诊断糖尿病的确诊试验。 OGTT 该怎么做？ 常于上午8～10时开始，受试者空腹（8～10h）后口服溶于300ml水内的无水葡萄糖粉75g，如用1分子水葡萄糖则为82.5g。 从服糖第1口开始计时，于服糖前和服糖后30min、1 h、2h、3h （一般不采）分别静脉取血测血糖. OGTT该怎用葡萄糖？ 有一个问题被绝大多数 …

2022年3月7日 · Thus “glucose tolerance test” is a valuable diagnostic aid in the diagnosis of diabetes mellitus, insulin resistance, impaired beta-cell functionnand sometimes reactive hypoglycemia and acromegaly. GTT is of two types depending upon the route of glucose administration : OGTT is mostly preferred and is explained in detail here.
