What is the Normal Variance in Blood Sugar During the Day?


Controlling blood sugar levels is an important part of life for people with Type 2 Diabetes. The first step is knowing what's normal. So what is the normal variance in blood sugar during the day?

  • Fasting blood sugar: this is the level that's measured after fasting (not eating) for 8 hours. Fasting sugar levels should normally be between 70-100 mg/dl.

  • After a meal, blood sugar shouldn't normally rise higher than 200 mg/dl. Good control for diabetics, two hours after a meal, should be somewhere around 120-150 mg/dl.

So the normal variance in blood sugar during the day is around 70-200 mg/dl. (see Type 2 Diabetes - What do the Test Results Mean? for more about blood sugar tests)

Diabetics should regularly test their blood sugar to ensure they stay within normal range. A diabetes treatment plan includes a healthy diet, regular exercise, and in some cases, medication to help manage the disease.
