Understanding Hypoglycemia
Hypoglycemia occurs when your blood sugar drops too low, causing symptoms like dizziness, confusion, and weakness. In non-diabetics, it can happen due to various reasons, such as skipping meals or strenuous physical activity. Whipple's triad is key in diagnosing hypoglycemia: symptoms, low blood sugar levels, and symptom relief after sugar intake.
Common Triggers for Hypoglycemia
For healthy individuals, the main causes of hypoglycemia can be endogenous hyperinsulinism or factitious hypoglycemia. In contrast, those with existing health issues might experience it due to medications, alcohol, or underlying illnesses like adrenal insufficiency. Identifying these triggers is crucial for effective management.

The Role of Whipple's Triad
Whipple's triad plays a vital role in hypoglycemia diagnosis. It consists of three criteria: experiencing symptoms that align with hypoglycemia, having a low blood glucose level confirmed by lab tests, and the resolution of symptoms once blood sugar levels are corrected. Meeting these criteria helps distinguish true hypoglycemia from other conditions.
