When a patient presents with headache and nausea symptoms, doctors will typically begin with a thorough medical history and physical examination to help diagnose the underlying cause of the symptoms. Some diagnostic tests that may be ordered include:
Blood tests to check for infection, inflammation, or other medical conditions.
Imaging tests such as CT scan or MRI to check for tumors, brain injury or other structural issues.
Electroencephalogram (EEG) to check for seizures or abnormal electrical activity in the brain.
Lumbar puncture (spinal tap) to check for meningitis or other inflammatory conditions.
Gastrointestinal tests such as endoscopy or colonoscopy to check for gastrointestinal issues.
Pregnancy test for women of childbearing age.
Doctors may also ask about the patient's symptoms, including when the headaches and nausea occur, what triggers them, and what medications or treatments have been tried. They may also ask about the patient's sleep patterns, dietary habits, and exposure to environmental toxins.
Based on the results of the examination, diagnostic tests and patient's history, doctors will make a diagnosis and develop a treatment plan for the patient. In some cases, the cause of the headache and nausea symptoms may not be immediately apparent, and further testing and monitoring may be needed. It is important to follow the doctor's recommendations and seek medical attention if symptoms worsen or persist.
