Adipsia; Lack of thirst; Absence of thirst

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:

• When did you first notice this problem?
• Did the absence of thirst develop suddenly or slowly?
• Is the thirst decreased or totally absent?
• Can you drink fluids?
• Did the loss of thirst follow a head injury?
• What other symptoms do you have?
• Do you have abdominal pain?
• Do you have headaches?
• Do you have difficulty swallowing?
• Do you suddenly dislike drinking fluids?
• Do you have difficulty breathing?
• Do you have a cough?
• Do you have any changes in appetite?
• Do you urinate less than usual?
• Do you have any changes in skin color?
• What medications are you taking?

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).
