Diagnosing the Cause of Nausea: From Simple Tests to Advanced Procedures

Initial Evaluation

Your doctor will start with a thorough medical history and physical examination. They'll ask about the timing and duration of your symptoms, associated factors, and any other health issues. A basic neurological exam may be performed to check for signs of inner ear or brain involvement. Blood tests and urinalysis are often ordered to check for infections, electrolyte imbalances, or other systemic issues.

Imaging Studies

If the cause isn't clear from initial tests, imaging may be recommended. An abdominal ultrasound can check for gallbladder issues or other abdominal organ problems. CT scans provide detailed images of your internal organs and can detect tumors or obstructions. For suspected neurological causes, an MRI of the brain might be ordered. In some cases, X-rays are used to look for intestinal obstructions.

Endoscopic Procedures

An upper endoscopy allows doctors to visually examine your esophagus, stomach, and upper small intestine using a flexible tube with a camera. This can detect ulcers, inflammation, or tumors. In some cases, a colonoscopy might be recommended to examine the large intestine. These procedures are usually performed under sedation for your comfort.
