Your blood sugar, or glucose, is your body’s primary source of energy. It comes from the food you eat. Insulin, a hormone produced by the pancreas, helps glucose from food get into your cells to be used for energy. When you have diabetes, your body either doesn’t make enough insulin or can’t effectively use the insulin it produces. This can lead to high blood sugar levels, which over time, can cause serious health problems like heart disease, kidney disease, and nerve damage.
Therefore, routinely monitoring your blood sugar levels and maintaining them within the normal range is vital for preventing these complications.
Understanding Blood Sugar Tests
Before we delve into normal ranges, let's briefly discuss the common blood sugar tests:
- Fasting Blood Sugar (FBS): Measured after an overnight fast (at least 8 hours).
- Postprandial Blood Sugar (PPBS): Measured 2 hours after starting a meal.
- A1C Test: Provides an average of your blood sugar control over the past 2-3 months.
- Random Blood Sugar (RBS): Measured at any time of day, regardless of when you last ate.
Each test provides a different snapshot of your blood sugar, and your doctor will likely use a combination of these tests to assess your overall glucose control.
Normal Blood Sugar Ranges: A Detailed Overview
The following ranges are generally accepted, but always consult with your doctor for personalized advice:
| Test | Normal Range (mg/dL) | Prediabetes Range (mg/dL) | Diabetes Range (mg/dL) |
|---|---|---|---|
| Fasting Blood Sugar (FBS) | 70-99 | 100-125 | 126 or higher |
| Postprandial Blood Sugar (PPBS) (2 hours after meal) | Less than 140 | 140-199 | 200 or higher |
| A1C | Less than 5.7% | 5.7%-6.4% | 6.5% or higher |
| Random Blood Sugar (RBS) | Varies; discuss with your doctor | Varies; discuss with your doctor | 200 or higher (with symptoms) |
Note: These values are general guidelines and can vary depending on individual factors. Always consult with your healthcare provider.
