Your Guide to Normal Blood Sugar Levels: A Simple Blood Sugar Chart
Understanding normal blood sugar levels is crucial for maintaining good health, especially if you have diabetes or are at risk. This guide provides a straightforward blood sugar chart and explains what those numbers mean for you. We'll cover pre- and post-meal ranges, factors that can affect your blood sugar, and tips for keeping your levels within a healthy range.
What are Normal Blood Sugar Levels?
Normal blood sugar levels vary depending on when you last ate and whether you have diabetes. Generally, doctors measure blood sugar levels in milligrams per deciliter (mg/dL). Understanding these ranges can help you monitor your health and take proactive steps to manage any potential issues. Let's look at some general guidelines.

- Postprandial Blood Sugar: This is the level measured one to two hours after eating a meal.
- HbA1c: This test provides an average of your blood sugar levels over the past two to three months.

For people with diabetes, the target ranges may differ. Always consult your doctor or healthcare provider for personalized guidelines. The general guidelines for people with diabetes are:

Several factors can influence your blood sugar levels, making it important to consider these variables when interpreting your readings.
- Diet: Carbohydrates, in particular, have a significant impact on blood sugar. Consuming sugary drinks and processed foods can cause rapid spikes.

- Stress: Stress hormones can increase blood sugar levels.
- Medications: Certain medications, such as steroids and some antidepressants, can affect blood sugar.
- Illness: Infections can temporarily raise blood sugar levels.
- Dehydration: Can increase blood sugar concentration.
- Menstrual Cycle: Hormonal changes can affect insulin sensitivity.
