"Sick days" are short periods of illness such as infections that last a few days (such as flu, viral fever and diarrhoea).

When unwell, your body releases stress hormones, which can raise blood glucose levels, even with minimal food intake. Additionally, ketone levels might increase.

A sick day plan is essential for managing glucose levels during these periods, in order to prevent diabetic ketoacidosis (DKA) and low blood glucose. 

Signs and Symptoms of DKA

Thirst
Increased frequency of urination
Nausea, vomitting and/or stomach pain
Difficulty breathing
Extreme fatigue
Drowsiness

What to do on sick days?

Prepare for sick days by collaborating with your healthcare team and learning what to do on a sick day. Having a sick day plan ensures effective management when unwell. 

During periods of illness, the first step is to check your blood glucose and blood ketone levels more frequently (every two hours).

If you are unable to check your blood ketones and you feel unwell, it is crucial to seek medical attention promptly.

In cases where your blood ketones exceed 3.0 mmol/L, it is imperative to visit the emergency department immediately.
