Flu and People with Diabetes

People with diabetes (type 1 or 2), even when well-managed, are at high risk of serious flu complications, which can result in hospitalization and sometimes even death. Pneumonia, bronchitis, sinus infections and ear infections are examples of flu-related complications.

Flu also can make chronic health problems, like diabetes, worse. This is because diabetes can make the immune system less able to fight infections. In addition, illness can make it harder to control your blood sugar. The illness might raise your sugar but sometimes people don’t feel like eating when they are sick, and this can cause blood sugar levels to fall. So it is important to follow the sick day guidelines for people with diabetes.

Diabetes is a chronic (long-lasting) disease that affects how your body turns food into energy. There are three main types of diabetes: type 1, type 2, and gestational diabetes (diabetes while pregnant). More than 100 million Americans are living with diabetes (30.3 million) or prediabetes (84.1 million).
