Esophageal manometry is generally safe, and complications are rare. But as with any medical procedure, it does carry a risk of complications.

During esophageal manometry, you may experience:

  • Gagging when the tube passes into your throat
  • Watery eyes
  • Slight nosebleed
  • Discomfort in your nose and throat

After esophageal manometry, you may have some mild side effects, including:

  • Sore throat
  • Stuffy nose
  • Minor nosebleed

Rarely, severe complications may include:

  • Irregular heartbeat
  • Stomach contents flowing back into your esophagus, which you breathe into your lungs (aspiration)
  • A hole in your esophagus (perforation)
