Tests for Esophageal Dysphagia
If you experience difficulty swallowing, frequent coughing or gagging while eating, or feel like food is stuck in your throat, your doctor may recommend one or more of the following tests to determine the severity of your dysphagia.
A barium liquid is swallowed and travels the length of your esophagus. X-ray images show how food and liquid travel through your esophagus.
Upper Endoscopy (EGD)
Your doctor inserts a flexible tube into your mouth to view the inside of your esophagus, stomach, and small intestine.
A tiny electronic device is inserted into your nose and guided to your esophagus via a thin, flexible tube called a catheter. It evaluates motility by monitoring strength and patterns of muscle function within the esophagus.
During endoscopy, your gastroenterologist uses a device to measure pressures inside your esophagus and assess esophageal motility.
