At the unspecified diagnosis and complaints to a polydipsia the following diagnostic algorithm is used:
Adequacy of a diuresis is estimated and is defined whether there are no losses of water exceeding physiological norm, for example with a liquid chair.
The electrolytic composition of blood is estimated, blood glucose level is defined, if necessary biochemical analysis of blood is made.
The filtering function of kidneys is estimated.
The examinations allowing to confirm the preliminary diagnosis are conducted.

So, for example, at active loss of water with then or at a considerable exercise stress water requirement can increase considerably. It is possible to refer increase in concentration of any substance in blood of the person to the pathological reasons of a similar state. For example, increase in level of glucose at a diabetes mellitus. Distinguish primary polydipsia and secondary. Primary arises at direct activation of the drinking center, for example at a pituitary gipotalomicheskoy of pathology, or as a result of mental disorders. Secondary is reaction to change of composition of the circulating blood.

The polydipsia at the expressed current leads to emergence of water and electrolytic disturbances in a human body. As a rule hypostases, ascites develop, at the kidneys expressed disturbances in combination with pathologies emergence of a convulsive syndrome is possible.
