Absence of thirst is a lack of the urge to drink fluids.
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. Drink enough fluids, even if you do not feel thirsty (6 - 8 glasses each day may be advised).
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).
