Can a Cold Affect Blood Sugar

Why can a cold cause blood sugar rise in diabetes patients?

If you catch a cold, you are likely to have blood sugar rise. When you get a cold, the body will send out hormones to fight against the foreign invaders to help battle the cold. However, the hormone to regulate the blood sugar decreases. As a result, the fluctuation of blood sugar occurs in diabetics. When you get a cold and meanwhile, it is very hard to control your blood sugar, you are at the high risk of ketoacidosis in type 1 diabetes, or hyperosmolar in type 2 diabetes.

What should you do with blood sugar when you catch a cold?

Regularly check your blood sugar at least four times one day. If your blood sugar level is too high, you need to increase the dose of insulin or medicines on high blood sugar. You need to alter your diabetes management strategy if your levels aren’t near your target blood sugar level.

Besides the insulin dose regulation, a diet change is necessary. The American Diabetes Association recommends trying to eat a food with about 15 grams of carbohydrates every hour or so. You might eat a 3-ounce fruit juice bar, 1/2 cup frozen yogurt, or 1/2 cup cooked cereal. If you don’t eat, your blood sugar might actually fall too low.

If you have a serious fever, drink more water in case of dehydration. But you remember that you can sip the liquid instead of drinking it all at once.
