Blood sugar levels chart for adults with diabetes
Your diabetes care team will set individual blood sugar targets, but as a general guide, the NHS recommends:
Each time you test your blood sugar, log it in a notebook, an online tool, in an app or connect your meter to a computer to download readings if it supports this.
Note the date, time, results, and any recent activities:
- Medication and dosage taken
- 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 could affect your eyes, kidneys and nerves. Diabetes doubles your risk of 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 different targets.
