Keep close track of your blood sugar and urine ketone levels
Continue taking your diabetes medication when you're sick, and remember to test your blood sugar often. You may need to adjust your insulin doses or other medications. If your blood sugar is higher than 300 milligrams per deciliter (mg/dL) or you're unable to keep fluids down, consult your doctor.
Here are some general guidelines:
- Type 1 diabetes. Check your blood sugar and urine ketone levels every four hours.
- Type 2 diabetes. Check your blood sugar levels four times a day. If your blood sugar is higher than 300 mg/dL, check your urine for ketones. Make sure your test strips haven't expired.
Excessively high blood sugar can lead to ketoacidosis, especially in people who have type 1 diabetes. People who have type 2 diabetes — particularly older adults — may develop a similar condition called hyperosmolar nonketotic coma. Both conditions can cause confusion, difficulty breathing or coma. Sometimes these conditions can be fatal.
Stick to your diabetes meal plan
With a minor illness such as a cold, you may be able to stick to your diabetes meal plan — which will help ensure blood sugar stability. Remember to check the sugar content of any over-the-counter medications you take. Many cough syrups and other liquid cold preparations are high in sugar.
If you have nausea, vomiting or diarrhea, you may not be able to eat your regular foods. But it's still important to get enough carbohydrates. Try these foods, which contain about 10 to 15 grams of carbohydrates:
- 1 double-stick frozen fruit pop
- 1 cup milk
- 1/2 cup fruit juice
- 1/2 cup regular soda (not diet)
- 6 saltine crackers
- 3 graham crackers
- 1 slice dry toast
- 1/2 cup regular (not artificially sweetened) gelatin
In addition to sipping fruit juice or sweetened beverages, drink at least 8 ounces of water or other calorie-free liquid every hour you're awake. If you're not able to keep anything down, remember to monitor your blood sugar closely and consult your doctor.
Know when to contact your doctor
Diabetes complications can quickly become dangerous. Contact your doctor if:
- Your blood sugar is higher than 300 mg/dL
- Your blood sugar is higher than 240 mg/dL for more than 24 hours
- Your urine ketone level is moderate to large
- You feel sleepier than usual or can't think clearly
- You vomit for more than six hours
- You have diarrhea for more than six hours
- You feel confused and can't think clearly
- Your lips and tongue appear dry and cracked
Think prevention
High blood sugar can weaken your immune system. This makes you more likely to get a cold or the flu — and more vulnerable to serious effects of common illnesses. To reduce the risk of getting sick:
- Get vaccinated against pneumococcal pneumonia and the flu.
- Wash your hands often.
- Don't touch your eyes or nose with your fingers.
- Avoid crowds during flu season.
- Wear a mask if you must be around someone with an upper respiratory infection.
No one plans to get sick, but it happens. Feel confident and secure in your ability to manage your diabetes by following your sick-day plan.
