What Is Blood Sugar?

Blood sugar refers to the current level of glucose in your bloodstream, typically measured in a fasting state. Depending on the result, it can be categorized as:

• Normal: 70–99 mg/dL
• Prediabetes: 100–125 mg/dL
• Diabetes: 126 mg/dL or higher

Blood sugar levels fluctuate throughout the day, influenced by factors such as meals, exercise, and stress.

What Is HbA1c?

HbA1c reflects the average blood sugar levels over the past 2–3 months. It measures the percentage of hemoglobin in your blood that is glycated (bound to glucose).

• Normal: Below 5.6%
• Prediabetes: 5.7–6.4%
• Diabetes: 6.5% or higher

Unlike blood sugar, HbA1c provides a long-term overview of your glucose control.

Metric	Measurement Timing	Timeframe Covered	Primary Use
Blood Sugar	Immediate	Current levels	Short-term glucose levels
HbA1c	Blood test	2–3 months	Long-term glucose trends

For example, even if your fasting blood sugar is within the normal range, a high HbA1c may indicate frequent post-meal spikes or other periods of high blood sugar.
