Upswing: A Bad Cold

Dehydration can elevate your blood sugar so it is wise to stay well hydrated. If you are sick, diarrhea and vomiting for more than two hours, or illness longer than a few days may alter your blood sugar. Moreover, blood sugar rises as your body tries to fight any type of illness. Medications such as antibiotics and decongestants may alter your blood sugar. Check your blood sugar levels during these intermittent special situations so you can help determine how your body will react to these illnesses and treatments.
