What are blood sugar levels?

The correct terminology for blood sugar levels is glycaemia, but is also known as blood sugar concentration or blood glucose level. Glycaemia is the concentration of glucose at any one time that a person has in their bloodstream.

Glucose is a type of sugar used by the body to provide energy and circulates in your bloodstream.

The hormone in your body, insulin produced in the pancreas regulates your blood sugar levels by releasing into the bloodstream to maintain normal levels.

Keeping your blood sugar levels within a safe range will ensure that it reduces the risk of diabetes or other illnesses, such as heart disease or stroke.

Normal blood sugar levels for the elderly and seniors (over 65)

Normal blood sugar levels for the elderly and seniors over the age of 65 are different from those of younger adults.

As we age muscle loss, disability, and frailty are more prevalent in men and women with diabetes and may be related to the presence of hyperglycemia or insulin resistance.

For those elderly and seniors who struggle to maintain healthy blood sugar levels should monitor what they eat and drink, their daily routines and do regular checks.

How is it best to monitor your blood sugar levels

You can use a device called a continuous glucose monitor (CGM) if you treat your diabetes with insulin. Or you can test your blood sugar at home with a portable electronic device called a blood sugar meter using a small drop of your blood.

A continuous glucose meter (CGM) is one way to check your blood sugar and you should already have one if you treat your diabetes with insulin.

Alternatively, you can test your blood sugar at home with the finger test prick method by using a portable electronic device ( the kit should have a needle (lancet) to prick your finger to extract blood, a digital display and somewhere you can insert a test strip.

The device should register a reading after a few seconds.

Tips on managing your blood sugar levels

If you are manually logging readings –

  • Record date of reading
  • Time
  • Result of test
  • Medication and dose
  • Dietary information
  • Exercise information

If recording electronically –

  • Many devices will allow you to download directly onto your phone or computer

Regular readings taken will show you what, if any, there is to pattern of results.

If you don’t get frequent results that fall within your target range goals, then contact your general practitioner (GP), or other suitable health care provider to discuss further.
