Why is it important to have blood glucose levels in the right range?

Our bodies are designed to operate at its best when our blood glucose levels are in a specific range.

When blood glucose levels become too low

If our blood glucose levels are too low, our ability to carry out mental and physical tasks becomes compromised.

For people who take insulin or certain medication that can cause low blood sugar levels (such as sulfonylureas and prandial glucose regulators), it is particularly important to prevent blood glucose levels going too low and causing hypoglycemia

When blood glucose levels become too high

If our blood glucose levels rise too high, this can have health implications in the short term and the long term.

If our blood sugar levels are consistently too high, it increases the risk of suffering the long term complications of diabetes including:

If blood glucose levels go very high, it can become dangerous in the short term.

People with type 1 diabetes may be at risk of developing a serious condition called ketoacidosis if blood glucose levels stay above 14 mmol/l for too long.

People with type 2 diabetes may be at risk of dangerous condition called Hyperosmolar Hyperglycemic Nonketotic Syndrome if blood glucose rise above 40 mmol/l.
