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 affects the eye in two ways: The changing blood sugar levels affect the lens of the eye and blood vessels in the retina Changes in the lens cause vision to blur with the changing blood sugar levels. The same fluctuations cause blood vessels to leak, including those in the eye.
