Summary
Early screening for type 2 diabetes in high-risk individuals is recommended. Fasting plasma glucose is the preferred screening test over the oral glucose tolerance test (OGTT).
Area of Science:
- Endocrinology
- Metabolic Diseases
- Preventive Medicine
Context:
- The clinical benefits of preclinical type 2 diabetes screening versus post-symptomatic diagnosis remain unclear.
- The preclinical phase of type 2 diabetes can extend for several years, offering a window for intervention.
- Opportunistic screening targets individuals aged 45+, with BMI ≥ 30, family history, hypertension, dyslipidemia, or cardiovascular disease.
Purpose:
- To evaluate the rationale and methods for preclinical type 2 diabetes screening.
- To provide guidance on screening test selection for type 2 diabetes.
Summary:
- Early intervention in preclinical type 2 diabetes may prevent long-term complications.
- Opportunistic screening is advised for specific high-risk demographics.
- Fasting plasma glucose measurement is the recommended primary screening method.
- The oral glucose tolerance test (OGTT) is no longer recommended for routine screening.
Impact:
- Informs clinical practice guidelines for type 2 diabetes detection.
- Potentially reduces the incidence of diabetic complications through early management.
- Optimizes resource allocation in diabetes screening programs.

Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
Diabetes: Symptoms, Diagnosis, and Complications
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is based on...
Hyperglycemia
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
Carbohydrate Metabolism
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
