Sick-Day Guidelines for People With Diabetes

Table of Contents


What happens when you are sick

If you have diabetes, other illnesses can make your blood sugar go up. This can be dangerous. When you're sick with the flu or another illness, your body releases hormones to fight infection. These hormones raise blood sugar levels. They also make it hard for insulin or other medicines to lower your blood sugar.

Sick-day guidelines

Work with your doctor to write a sick-day plan for how to help prevent high blood sugar when you're sick. Keep your plan in a handy place, and let your family know where you keep the plan.

Here are some general sick-day guidelines.
