Patient Information: Timed Barium Esophagogram

A timed barium esophagogram is a safe, non-surgical imaging test that helps assess how well your esophagus (food pipe) empties and can help diagnose swallowing problems or monitor the effect of treatment for esophageal conditions such as achalasia.

Purpose of the Test

• Assess esophageal emptying.

• Diagnose or monitor esophageal motility disorders, especially achalasia.

• Evaluate symptoms like difficulty swallowing (dysphagia).

Preparation Instructions

• Fast overnight: Do not eat or drink anything from the night before the test.

• Follow any additional instructions provided by your healthcare provider.

What Happens During the Test

• Stand upright for the procedure.

• Swallow a fixed amount (usually 100–250mL) of low-density barium liquid in 15–20 seconds.

• Sequential X-ray images are taken at 1, 2, and 5 minutes after swallowing (sometimes just 1 and 5 minutes).

• You will be asked not to move while the X-rays are obtained.

What to Expect

• You may feel the barium is chalky but it is usually well tolerated.

• The procedure is not painful.

• After the test, you might notice lighter-colored stools for 1–2 days as the barium passes.

Post-Test Advice

• Resume normal diet unless instructed otherwise.

• Drink extra fluids to help clear the barium from your system.

• If you have constipation or notice unusual symptoms after the test, contact your healthcare provider.

Understanding Results

• The height and width of the barium column on X-ray give an objective measure of esophageal emptying; improvement after treatment indicates success.

• Your doctor will explain what your results mean and next steps.
