Introduction to the respiratory system organs: The respiratory system is the system of the human body by which it produces energy needed for life processes. 1  This energy is produced by the breaking down of glucose molecules in all living cells of the human body.
The most susceptible organs and systems effected by diabetes are the eyes, the kidneys, the nerves, the cardiovascular system. The only system I recall not being effected by diabetes is the respiratory system but I can't be 100% on that.
Diabetes does not directly affect the respiratory system. Complications from diabetes specifically are usually cardiac, resulting in heart disease, high blood pressure and strokes. However, due the the disease's deterioration of the body, eventually respiratory symptoms can arise, but they are not seen as official and direct symptoms.
