When You’re Sick and Have Diabetes
Take care of yourself when you’re sick. Being sick can make your blood glucose go too high. Here are some tips on what to do:
* Check your blood glucose level every 4 hours. Write down the results.
* Keep taking your diabetes medicine. You need it even if you can’t keep food down.
* Drink at least one cup (8 ounces) of water or other calorie-free, caffeine-free liquid every hour while you’re awake.
* If you can’t eat your usual food, try drinking juice or eating crackers, popsicles, or soup.
* If you can’t eat at all, drink clear liquids such as ginger ale. Eat or drink something with sugar in it if you have trouble keeping food down, because you still need calories. If you can’t eat enough, you increase your risk of low blood glucose (hypoglycemia).
* In people with type 1 diabetes, when blood glucose is very high, the body produces ketones. Ketones can make you very sick. Test your urine for ketones if
o your blood glucose is over 24 o you can’t keep food or liquids down
* Call your health care provider right away if
o your blood glucose has been over 240 for longer than a day
o you have moderate to large amounts of ketones in your urine
o you feel sleepier than usual
o you have trouble breathing
o you can’t think clearly
o you throw up more than once
o you’ve had diarrhea for more than 6 hours
