The health care provider will take a medical history and perform a physical examination.
Medical history questions may include:
- When did you first notice this problem?
- Did the absence of thirst develop suddenly or slowly?
- Is the thirst decreased or totally absent?
- Are you able to 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 medicines 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.
Based on your evaluation and any tests, your health care provider will recommend treatment if needed.
If you are dehydrated, fluids will likely be given through a vein (IV).
