Sick days

It is important to be prepared and to know what to do if you get sick.

This includes having a personalised sick day action plan, and a sick day kit ready to use at the earliest sign of illness.

Being unwell can make it more challenging to keep glucose levels in your target range. This is because of the stress hormones your body releases when you are sick. Stress hormones increase the amount of glucose the liver releases into the bloodstream. They can make it difficult to keep your blood glucose levels from rising too high.

Start following your sick day action plan immediately if you feel unwell or have any signs of illness.

Let a friend or family member know that you are unwell.

Make sure you keep a list of contact numbers by the phone of your:

  • support people
  • doctor
  • diabetes nurse practitioner
  • diabetes educator
  • local hospital or medical centre.

Be prepared before you get sick. Read more about sick days.

A sick day action plan is step-by-step written instructions on how to manage your diabetes when you are unwell.

Your doctor, diabetes nurse practitioner or diabetes educator can work with you to develop your personalised sick day action plan. Talk with family and friends about your sick day action plan and the help and support you might need when unwell.

The plan should be reviewed every 1–2 years.

A sick day kit will contain additional items you might need when feeling unwell, which means you don’t have to organise them when feeling unwell.

Check your sick day kit every three months to make sure it is up to date and restock your kit if you have used it.

Our fact sheets have a list of items to include in your sick day kit.

Talk to your doctor, diabetes nurse practitioner or diabetes educator for advice on making changes to your insulin. They will work with you to develop your personalised sick day action plan. Your sick day action plan should tell you how to manage your insulin doses when you are unwell.

It is very important to keep up your fluid intake. This will reduce your risk of you becoming dehydrated. It is also very important to keep up your carbohydrate (carb) intake when you feel unwell to reduce your risk of a hypoglycaemia (also known as hypo or low blood glucose levels).

If you have type 1 diabetes and your blood glucose levels are higher than 15 mmol/L, make sure you check for ketones before you exercise. It can be dangerous to exercise when blood glucose levels are high and/ or ketones are present. This means you do not have enough insulin in your bloodstream for your muscles to use glucose for energy. It can lead to rising blood glucose levels, a build-up of ketones and diabetic ketoacidosis (DKA). Ask your doctor or diabetes nurse practitioner about extra insulin doses to help bring your blood glucose levels back into the target range.
