It is very common to see that blood sugar rises during illness and infection. This rise in blood sugar is difficult to control. Why?
Some reasons:
1.) The body releases extra glucose in circulation, during illness or infection. This can lead to rise in blood sugar.
2.) The hormones produced to fight infection or illness, specially cortisol also increases the blood sugar levels.
What to do during these times:
1.) Keep hydrated- High blood glucose levels can lead to dehydration. So, make sure you are regularity drinking fluid to stay hydrated.
2.) Keep eating- When sick, it is difficult to eat but this will lead to more ketones as the body may need to breakdown fat to make fuel. So, if eating is difficult, or there is vomiting, unable to retain, it is advisable to have drinks with carbohydrate.
3.) Keep taking medicines- If you can self manage adjust the dose of insulin.
If you are a type 1 diabetic, keep testing for ketones with each blood sugar test. Hyperglycemia in critically ill patients should always be treated in a hospital.
