Maintaining healthy blood glucose

A healthy blood glucose level (BGL) is something everyone should aim for.

The ‘normal’ range of blood glucose levels for a person who does not have diabetes is between 4mmol/L and 7.8mmol/L.

If you have diabetes, you should still aim to have BGLs close to this range, however, it is very important that you discuss this with your doctor or healthcare team.

Your target BGL range may vary from the normal range depending on a range of factors, including your age, how long you have had diabetes, the type of medication you are taking and whether you have other health conditions.

Your healthcare team will help you set a BGL target range that is right and safe for you.

How can I keep my blood glucose in my target range?

There are several common factors that will cause your BGLs to increase or decrease. If your BGLs are outside your target range it may be due to:

  • the foods you eat, especially the amount of carbohydrates you eat
  • your level of physical activity
  • any illness or pain
  • emotional stress
  • alcohol consumption
  • medication for diabetes and any other health condition.

You should also make sure that any unexplained increases or decreases in your BGLs are not due to testing techniques. Read our blood glucose testing checklist.

If your BGL is going up and down more than usual, you should seek advice from your doctor or healthcare team.
