Study Notes
Diabetes Mellitus Overview
- Chronic disorder affecting carbohydrate, fat, and protein metabolism.
- Characterized by insulin deficiency, leading to hyperglycemia.
- Insulin deficiency can be relative or absolute.
Insulin Synthesis
- Primary stimulus for insulin synthesis from pancreatic beta cells is glucose.
- Additional agents also play a role in stimulating insulin release.
- C-peptide levels are used to assess insulin levels in the body.
Diagnosis Criteria
- Random Glucose Test: A reading of ≥ 200 mg/dL (11.1 mmol/L) combined with clinical symptoms indicates diabetes.
- Fasting Glucose Test: A fasting glucose level of ≥ 126 mg/dL (7.0 mmol/L) must be confirmed on multiple occasions for diagnosis.
- Oral Glucose Tolerance Test (OGTT): A 2-hour glucose level exceeding 200 mg/dL (11.1 mmol/L) after a standard 75g glucose load is indicative of diabetes.
