What is the normal blood sugar level (BSL) range?

The normal blood sugar level (BSL) range for a healthy individual is typically considered to be between 4.0 and 7.8 mmol/L. This range reflects the values that are generally accepted in clinical practice for fasting and postprandial (after meals) glucose levels. Maintaining blood sugar levels within this range is essential for overall health, as both hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) can lead to serious health implications.

This range is supported by guidelines from various health organizations and reflects the body's typical ability to regulate glucose through insulin and other metabolic processes. Understanding this normal range is crucial for healthcare providers in monitoring and managing patients at risk for diabetes or other metabolic disorders.
