diabetes-related changes in the CNS and the changes seen commonly with age is remarkable. On the other hand, tissues with high replicative capacity such as intestinal epithelium and bone marrow do not demonstrate a high level of concordance between the changes in diabetes and those seen with age (see Table 56.2). These tissues do not appear to undergo premature aging in diabetes. It is likely that accelerated aging in diabetes is tissue-specific, and it may be limited to tissues without a high capacity of replication.

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
