Blood Sugar Levels for Adults With Diabetes

Chart Normal Blood Sugar Level Adults

Each time you test your blood sugar, log it in a notebook or online tool or with an app. Note the date, time, results, and any recent activities:

  • What medication and dosage you took
  • What you ate
  • How much and what kind of exercise you were doing

That will help you and your doctor see how your treatment is working.

Well-managed diabetes can delay or prevent complications that affect your eyes, kidneys, and nerves. Diabetes doubles your risk for heart disease and stroke, too. Fortunately, controlling your blood sugar will also make these problems less likely.

Tight blood sugar control, however, means a greater chance of low blood sugar levels, so your doctor may suggest higher targets.
