Elevated blood sugars over long periods lead to damage to many organs. Involvement of retina leads to blindness in some people; involvement of kidney is one of the most common cause for kidney failure; involvement of nerves lead to neuropathy leading to numbness; involvement of heart may lead to heart failure; involvement of blood vessels due to atherosclerosis will lead to heart and brain strokes and leg amputations. High blood sugars reduce immunity and encourage opportunistic infections.
