Insulin is made in the pancreas. If no or insufficient insulin is made, or when the body no longer responds to insulin, the body has trouble to get glucose from the blood. The blood flows remains around and can not be used for energy. The result is very thirsty and urinating a lot. Because the body tries to glucose in a different way to lose. As someone not glucose, so no power can take, he feels tired.
