Tests and diagnosis

By Mayo Clinic Staff

During the physical exam, your doctor may perform a neurological exam, to check your:

  • Reflexes
  • Muscle strength
  • Muscle tone
  • Sight and sense of touch
  • Coordination
  • Balance

If 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.
