Diabetes is not an infectious or contagious disease. Scientists don't know for sure exactly what causes the disorder, but it can't be caught from another person, like a cold or the flu. There, does, however, appear to be a genetic link with type 2 diabetes: If a family member has the condition, you're at higher risk for the disease.

Myth #5: There's only one dangerous kind of diabetes.
