If you experience hyperglycaemia regularly, you should speak to your doctor or diabetes care team.

It can affect people with type 1 diabetes and type 2 diabetes, as well as pregnant women with gestational diabetes. Hyperglycaemia can be potentially dangerous if blood sugar levels become very high or stay high for long periods.

Your blood sugar levels, also known as blood glucose levels, are a measurement that show how much glucose you have in your blood.

Diabetes UK says: “Your blood sugar levels go up and down throughout the day and for people living with diabetes these changes are larger and happen more often than in people who don't have diabetes.”

The NHS notes that if you have diabetes, “no matter how careful you are, you're likely to experience hyperglycaemia” at some point - the Express reports.

It adds: “Occasional mild episodes are not usually a cause for concern and can be treated quite easily or may return to normal on their own.

“But hyperglycaemia can be potentially dangerous if blood sugar levels become very high or stay high for long periods.”

In some cases, there may be no symptoms until the blood sugar level is very high, though you may spot some when you go to the toilet.

Symptoms of hyperglycaemia include needing to pee frequently and bladder infections.

Other symptoms of hyperglycaemia include increased thirst and a dry mouth, tiredness, blurred vision, unintentional weight loss and tummy pain.

You may also find that you are feeling or being sick, or that your breath smells fruity.

Diabetes UK says that if you take certain medication, like insulin or sulphonylureas, checking your blood sugars is a “vital part of living with diabetes”.

It adds that routine checks can help you know when you might be starting to go too low, called a hypo, or too high, called a hyper.

The charity adds that more and more people with diabetes are choosing to use a flash glucose monitor to check their sugar levels, which is a sensor you wear on your skin and that you don’t have to prick your finger to use.

It is normal for blood glucose levels to go up and down slightly throughout the day. Nonetheless, there are a number of ways you may be able to treat hyperglycaemia.
