Thirst, absent

Alternative names:

absence of thirst; adipsia; lack of thirst

Definition:

A lack of thirst.

Considerations:

The absence of thirst at various times during the day is normal, if the body is not requiring fluid replacement. However, when the body needs fluid replacement and there is still a lack of thirst then see your health care provider right away.

Common causes:

• hypothalamic injury or tumor (the hypothalamus is a small area in the brain; it secretes hormones that control many of the internal body processes including thirst)
• head injury
• bronchial tumor (SIADH conditions)
• cirrhosis
