An illness plan for people with diabetes usually covers things like:

• How often to test blood sugar and what the target range is.
• Whether and how to adjust the dose and timing of insulin or other diabetes medicines.
• What to do if you have trouble keeping food or fluids down.
• When to call your doctor.

The plan is designed to help keep your diabetes in control even though you are sick. When you have diabetes, even a minor illness can cause problems.
