Blood sugar is the amount of glucose in your blood. Your blood sugar level rises after you eat, and then it goes back down as your body uses the glucose for energy.

There is a range of blood sugar levels that are considered safe. This range varies depending on your age, health status, and whether or not you have diabetes.

Normal Blood Sugar Levels

For people without diabetes, the following blood sugar levels are considered normal:

  • Fasting blood sugar: 70 to 99 mg/dL
  • 2 hours after a meal: 80 to 130 mg/dL

Blood Sugar Levels in People with Diabetes

People with diabetes need to keep their blood sugar levels within a narrower range than people without diabetes. The target blood sugar levels for people with diabetes vary depending on the type of diabetes and the individual’s health goals.

For people with type 1 diabetes, the target blood sugar levels are usually:

  • Fasting blood sugar: 80 to 130 mg/dL
  • 2 hours after a meal: 100 to 180 mg/dL

For people with type 2 diabetes, the target blood sugar levels are usually:
