Why Is Blood Sugar Important?

Blood sugar, or glucose, is the main source of energy for your body's cells. It comes from the food you eat. The hormone insulin, produced by the pancreas, helps glucose from food get into your cells to be used for energy. Problems arise when your body doesn't make enough insulin or can't effectively use the insulin it produces. This can lead to high blood sugar levels (hyperglycemia) or low blood sugar levels (hypoglycemia). Both extremes can have serious health consequences. Maintaining stable blood sugar levels is essential for optimal bodily function.

What Is a Normal Blood Sugar Level?

Normal blood sugar levels vary depending on when you check them. Here are general guidelines:

• Fasting Blood Sugar: Measured after at least eight hours of fasting (typically overnight).
• Before a Meal: Checked right before eating.
• After a Meal (1-2 hours): Measured one or two hours after starting a meal.
• HbA1c: Provides an average blood sugar level over the past 2-3 months. This isn’t a single reading but an overall average.

Let's break down the specific target ranges:

Normal Blood Sugar Levels for Non-Diabetics

| Time of Day | Normal Range (mg/dL) | |-----------------------------|-----------------------| | Fasting | 70-99 | | Before a Meal | 70-99 | | 1-2 Hours After a Meal | Less than 140 | | HbA1c | Less than 5.7% |

Blood Sugar Levels for People with Diabetes

Target ranges may be different for people with diabetes and should be discussed with their healthcare provider. General guidelines often suggest:

| Time of Day | Target Range (mg/dL) | |-----------------------------|-----------------------| | Fasting | 80-130 | | Before a Meal | 80-130 | | 1-2 Hours After a Meal | Less than 180 | | HbA1c | Less than 7.0% |

Important Note: These are general guidelines, and your individual target ranges may vary based on factors like age, overall health, and specific diabetes medications. Always consult with your doctor to determine the most appropriate targets for you.
