What is Diabetes? - UPSC Science And Technology
What is What is Diabetes? in UPSC Science And Technology?
What is Diabetes? is a key topic under Science And Technology for UPSC Civil Services Examination. Key points include: Diabetes Mellitus (DM) is a disorder of elevated blood sugar (glucose) due to insufficient insulin or abnormal insulin response.. Insulin is a hormone produced by the pancreas, crucial for glucose uptake by cells.. Fasting blood glucose levels define normal (70-110 mg/dL), prediabetes (100-125 mg/dL), and diabetes (≥126 mg/dL).. Understanding this topic is essential for both UPSC Prelims and Mains preparation.

📖 Introduction
Understanding Diabetes Mellitus (DM)
Diabetes, also known as Diabetes Mellitus (DM), is a prevalent medical condition characterized by the body's inability to effectively manage blood sugar (glucose) levels.
This disorder stems from two primary issues: either the body produces an insufficient amount of insulin, or it exhibits an abnormal response to the insulin it produces.
The core problem in Diabetes Mellitus is the dysregulation of blood glucose, leading to persistently high levels in the bloodstream. Insulin is the crucial hormone responsible for allowing glucose to enter cells for energy.
Blood Glucose Level Classifications
To diagnose and categorize an individual's glucose metabolism, specific blood glucose level thresholds are used, particularly for fasting blood glucose measurements.
These levels help differentiate between a normal state, a pre-diabetic condition, and confirmed diabetes.
- Normal Fasting Blood Glucose: Levels between 70–110 mg/dL are considered healthy.
- Prediabetes: Blood glucose levels ranging from 100 mg/dL to 125 mg/dL indicate prediabetes, a warning stage.
- Diabetes: A fasting blood glucose level of 126 mg/dL or higher is officially diagnosed as diabetes.
For UPSC Prelims, remember the exact numerical ranges for normal, prediabetes, and diabetes. For UPSC Mains, understand the underlying mechanisms of insulin insufficiency and abnormal insulin response.
