Swallowing examination

The swallowing examination under fluoroscopy observes the real-time function and structure of your throat to diagnose deglutition (swallowing) problems such as:

  • Difficulty chewing or controlling food or liquids in your mouth
  • Any choking caused by food or liquid entering your airways (aspiration)
  • Food lodging in your throat when you eat
  • Pain when swallowing

Examination procedure

For the procedure, you must:

  • Wear a hospital gown and remove jewelry and any metal object that might adversely affect image quality
  • Drink barium, a liquid contrast agent with a slight flavour or vanilla or strawberry

The radiologist will view your deglutition mechanism in real time as you swallow (progression from mouth to esophagus)

Please note that the total duration of your visit for this examination can be between 30 and 60 minutes, even though the examination procedure itself will only last between 5 and 10 minutes.

Preparing for the Examination (for adults)

To properly prepare for the examination, please follow the procedure below:

  • If your appointment is in the morning, no solid food should be eaten after 8:00 p.m. the evening before the exam. However, you may drink water until midnight. If your appointment is in the afternoon, you must adhere to an 8 hour fast.
  • On the day of the examination, you should be fasting. You should not smoke or chew gum.
  • If you need to take any medicine, it should be taken after your test.

A medical prescription is required to perform this examination.
