Psychogenic polydipsia must be differentiated from other causes of polyuria and polydipsia.

Disease Causes Symptoms Diagnosis and treatment
SIADH SIADH is a syndrome characterized by excessive release of antidiuretic hormone (ADH or vasopressin) from the posterior pituitary gland or another source. The result is hyponatremia, and sometimes fluid overload
  • Urine sodium concentration>40mmol/litre
Cerebral salt wasting syndrome Cerebral salt wasting syndrome is defined as therenal loss of sodium during intracranial disease leading to hyponatremia and a decrease in extracellular fluid volume The patient is Treatment is
Adrenal insufficiency Adrenal insufficiency

Adrenal insufficiency can be

Common causes of primary adrenal insufficiency:

Chronic disease is characterized by

Acute addisonian crisis is characterized by:

The diagnosis of Addisons disease is made through rapid ACTH administration and measurement of cortisol.

The definitive diagnosis is the cosyntropin or ACTH stimulation test. Acortisol level is obtained before and after administering ACTH. A normal person should show a brisk rise in cortisol level after ACTH administration.


Management: The management of Addison disease involves:

Adrenal crisis:

Hypopituitarism Abnormality in anterior pituitary function

Etiology is as follows:

Signs and symptoms ofhypopituitarism vary, depending on the deficient

hormone and severity of the disorder,some of the symptoms may be as follows:

The treatment of permanent hypopituitarism consists of replacement of the peripheral hormones

Hypothyroidism Hypofunctioning of the thyroid gland due to multifactorial etiology ranging from congenital to autoimmune causes described below: Diagnosis of hypothyroidism is based on blood tests:
Psychogenic polydipsia Also called as primary polydipsia is characterized bypolyuria and polydipsia. Causes are: Evaluation ofpsychiatric patients with polydipsia requires an evaluation for other medical causes of polydipsia, polyuria,hyponatremia, and the syndrome of inappropriate secretion of antidiuretic hormone.
  • The management strategy inpsychiatric patients should include:
