2. Pathologic
(1) diabetes: diabetes mellitus patients due to insulin secretion is insufficient, so that the blood glucose concentration in the blood significantly higher, resulting in increased plasma osmolality, the body in order to reduce osmolality will be over-absorption of intracellular water, and then there is the phenomenon of thirst, can be accompanied by more food, drink, urinate and other symptoms.
