High blood sugar is known medically as hyperglycaemia and occurs commonly in people with diabetes. It’s important to learn how to manage high blood sugar levels as it can have serious implications if left untreated over a long period of time, causing damage to the kidneys, nerves and eyes. Let’s take a look at some of the symptoms of high blood sugar and what you can do to manage it. 

Symptoms of High Blood Sugar

Symptoms of hyperglycaemia include:


  • Nausea or vomiting 
  • Dry mouth and fruity-smelling breath
  • Increased thirst
  • Needing to go to the toilet a lot

It’s important to note that you can experience symptoms other than these or even have no symptoms at all until you’ve had high blood sugar for a prolonged period of time. 

Causes of High Blood Sugar Levels

There are many causes of high blood sugar levels; these can include:

  • Missing a dose or taking an incorrect dose of your diabetes medication

How to Monitor Your Blood Sugar Levels

If you want to monitor your blood sugar levels yourself, an at-home testing kit is very useful. These work by pricking your finger and applying a drop of blood to a test strip before inserting it into the monitor for reading. Remember to keep track of your results, so you learn what’s normal for you. 

Alternatively, you can ask your doctor to check your blood sugar levels for you.
