diabetes
A chronic disease in which the body is either unable to produce enough of the hormone insulin or unable to use insulin efficiently. This results in high levels of sugar (glucose) in the blood and can lead to heart and kidney disease, nerve damage, vision loss and other complications. Insulin-dependent diabetes (type 1) usually appears before age 30; non-insulin-dependent diabetes (type 2) develops later and accounts for 90% of cases.
