Managing Hyperglycemia

When blood glucose levels are higher than your target range, it's called hyperglycemia.


It can be caused by:

  • Overeating, or eating more than usual
  • Missing a dose of medication or insulin
  • An out-of-the-ordinary event (for example, illness, stress, excitement)
  • A sudden mood change (for example, extreme fright, anger or sadness)
  • Pregnancy
  • Less activity than normal

If you experience hyperglycemia, you might experience:

  • Extreme thirst
  • More frequent urination
  • Dry and flushed skin
  • Mood swings
  • Unusual fatigue
  • Weight loss

When your blood glucose levels are very high, your body tries to get energy from the fat and muscle in your body. When this happens, and the body starts to break down fat and muscle, it produces something called ketones. Your body tries to get rid of ketones by passing them through your kidneys and out in the urine. Ketones in combination with high blood glucose can cause something called diabetic ketoacidosis (or DKA, for short), which is a medical emergency. It's very rare for people with type 2 diabetes to develop DKA, but you should be aware of the signs, just in case.

Symptoms of DKA can include:

  • Frequent urination or thirst for more than a day
  • Fatigue
  • Nausea and vomiting
  • Stiffness or aching in the muscles
  • Confusion
  • Rapid breathing
  • Breath that smells "fruity"
  • Headache
  • Loss of consciousness
  • Difficulty breathing when lying down
  • Abdominal pain

People with type 1 diabetes should be able to test for ketones at home. This can be done by testing your urine or using a blood glucose monitor that can measure ketones

DKA is a medical emergency, so if you suspect that you have symptoms, ask someone take you to the nearest hospital emergency room or call an ambulance immediately.
