Each grain of starch that is taken as food, when acted on by the saliva or pancreatic fluid, is converted into sugar, and becomes a source of fuel or power, and ultimately passes out of the body as carbonic acid and water. In diabetes the starch is still changed into sugar; but in the circulation and in the extravascular or parenchymatous structures the further change is partly or wholly stopped; more or less of the sugar remains as sugar, part reaches the kidneys and is thrown out in the urine, part exists in the structures unchanged; and thus the system is deprived of one part of that conversion of latent into active force on which the nutrition and power of the organs depends. In the body or out of the body, when once a series of chemical actions is set up, the series tends to become continu- ous; it propagates itself, unless a change of conditions occurs.
