When you are ill with something such as an infection, flu, or cold, your diabetes can be affected. Your blood sugar may go up, and you may begin to have ketones in you urine. For these reasons, it is important that you check your blood sugar more often when you are sick. Never avoid doing this, even if you are not able to eat. Drinks that contain sugar will help you get the calories your body needs for energy while you are sick.
Fluids are important to prevent dehydration.
C. Test your blood sugar and test your urine for ketones four time a day while you are sick. Re- check in 4 hours. If ketones are moderate or large, you need extra regular insulin. Add the total number of units you take a day. Divide this number by four.
