To determine if your heartburn is a symptom of GERD, your doctor may recommend:

  • X-ray, to view the shape and condition of your esophagus and stomach.
  • Endoscopy, to check for abnormalities in your esophagus. A tissue sample (biopsy) may be taken for analysis.
  • Ambulatory acid probe tests, to identify when, and for how long, stomach acid backs up into your esophagus. An acid monitor that is placed in your esophagus connects to a small computer that you wear around your waist or on a strap over your shoulder.
  • Esophageal motility testing, to measure movement and pressure in your esophagus.
