When you have diabetes and catch a cold, flu, or stomach bug, it's important to manage your blood sugar levels carefully to avoid complications. Here are some steps you can take: 1. Monitor your blood sugar levels more frequently than usual. Illness can cause your blood sugar to rise. 2. Stay hydrated by drinking plenty of fluids. Opt for calorie-free liquids like water, diet soda, or clear broth. 3. Eat or drink 30 to 50 grams of carbohydrates every 3 to 4 hours to keep your body nourished and prevent your blood sugar from dropping too low. 4. If you have trouble eating, try bland foods such as crackers, toast, or applesauce. 5. Keep taking your diabetes medications, but consult your doctor if you need to adjust the dosage. 6. Check for ketones if your blood sugar is high, as this can be a sign of a serious condition called diabetic ketoacidosis. 7. Contact your doctor if you have persistent vomiting or diarrhea, a fever, or if your blood sugar levels remain high despite taking your medications. By following these steps, you can manage your diabetes effectively even when you're sick.
