Whilst diabetes does not increase your risk of catching Covid-19 it can make the infection. When diabetics get an infection their BG (blood glucose) can rise rapidly - a state known as hyperglycemia. As the BG rises ketoacidosis (ketones in the blood). This is more common insulin dependant diabetes. This usually occurs as BG passes 14. However, with a Covid-19 infection this occurs earlier at around 10 or even below. Therefore if you are diabetic and develop a fever or continuous cough it is important to check for ketones as well as well as your BG. Fully blown ketoacidosis is very unpleasant and potentially fatal.
Test strips can be prescribed by your GP or DSN (diabetes specialist nurse).
