Diabetes is contagious is a myth, diabetes is not like a cold, flu or disease that can be passed from one human being to another. Diabetes is a disease in which the pancreas does not produce the insulin that is needed to keep the blood glucose level in a normal range.

The person that is diagnosed with diabetes has factors that cause their blood sugar level to be uncontrollable naturally. This can be from a combination of things, like family history and lifestyle, because diet can play a role in this diagnosis for people that have genetic factors. What this means is it is blood relatives that can be diagnosed with a form of diabetes, not spouses, friends or strangers that come in contact with the diabetic.
