Adipsia; Lack of thirst; Absence of thirst
Absence of thirst is a lack of the urge to drink fluids, even when the body is low on water or has an excess amount of salt.
Not being thirsty at various times during the day is normal, if the body does not need fluid replacement. However, a quick change in the need for fluids should prompt a visit to your doctor.
Follow your health care provider's recommendations.
Call for an appointment with your health care provider if you notice any abnormal lack of thirst.
The health care provider will take a medical history and perform a physical examination.
Medical history questions may include the following:
The physical examination may include a detailed nervous system examination if the health care provider suspects a head injury or problem with the hypothalamus. Diagnostic tests will vary depending on the history and physical examination findings.
Necessary fluids may be given through a vein (IV).
