Does getting a cold or flu affect my Diabetes?

When people are sick, whether it is an infection or virus, the body is under stress. During this time, hormones are released to help fight disease and to deal with the stress. These hormones can raise blood sugar levels and affect the action of insulin. Therefore, when you are sick, you may have a more difficult time keeping your blood glucose levels within target range. During times of illness, it is important to monitor your blood glucose levels and urine ketones more frequently. Ketones are more likely to build up when you are sick and lead to a condition called ketoacidosis.

You should contact your doctor immediately if your blood glucose levels remain high and/or you test positive for ketones in your urine. We recommend talking to your physician about developing a “sick day plan” before you become ill.
