Get StartedTests and diagnosis
By Mayo Clinic staffIf your doctor suspects an underlying medical condition may be causing your hiccups, he or she may recommend one or more of the following tests:
Laboratory tests
Samples of your blood may be checked for signs of:
- Infection
- Diabetes
- Kidney disease
Imaging tests
These types of tests may be able to detect anatomical abnormalities that may be affecting the vagus nerve, phrenic nerve or diaphragm. Imaging tests may include:
- Chest X-ray
- Computerized tomography (CT) scan
- Magnetic resonance imaging (MRI)
Endoscopic tests
These procedures utilize a thin, flexible tube containing a tiny camera, which is passed down your throat to check for problems in your esophagus or windpipe.
