Heartburn is a common complaint in adults, especially after eating a hearty or spicy meal. Yet, infants and children also can experience that burning sensation in the chest. According to some estimates, about 2% of children ages 3 to 9, and 5% of children ages 10 to 17, have heartburn. Symptoms can even start in infancy.
A few people have GERD that doesn't respond to treatment. Or they may have other concerning symptoms, such as weight loss, difficulty swallowing, anemia, or black stools. If you're one of them, you may need any of the following tests.
Diagnosing Acid Reflux With a Barium Swallow Radiograph
Your doctor may decide to use a special X-ray procedure -- the barium swallow radiograph -- to rule out any structural problems in your esophagus. In this painless acid reflux test, you will be asked to swallow a solution of barium. The barium enables doctors to take X-rays of your esophagus.
Barium swallow isn't a surefire method of diagnosing GERD. Only one out of every three people with GERD has esophageal changes that are visible on X-rays.
