Diagnosing Acid Reflux (Heartburn) in Children
Acid reflux in children, also known as gastroesophageal reflux (GER), is a condition where the contents of the stomach flow back into the esophagus—a muscular tube that connects your throat to your stomach—causing irritation and discomfort.
To diagnose acid reflux in children, doctors use a combination of reviewing the child's symptoms and medical history, as well as conducting various examinations, tests, and procedures. These help confirm the diagnosis and determine the type, severity, or stage of acid reflux. Specialists who may be involved in diagnosing acid reflux in children include gastroenterologists, surgeons, or other healthcare professionals.
Here are the examinations, screening tests, and procedures used to diagnose acid reflux in children:
- Upper Gastrointestinal (GI) Endoscopy: A flexible tube with a camera is used to look at the esophagus and stomach. This allows doctors to check for any inflammation or damage from acid reflux.
- Esophageal pH Monitoring: This test measures acid levels in the esophagus over 24 hours. A thin tube is placed in the esophagus to monitor if too much acid is present.
- Upper GI Series: This X-ray test uses a chalky liquid called barium to help show the shape of the esophagus, stomach, and small intestine. It can reveal any structural issues or blockages that may be causing acid reflux.
Additionally, doctors may perform other tests to rule out different causes for the symptoms. These may include stool tests, urine tests, blood tests, or breath tests to check for infections, stomach ulcers, or food intolerances.
To determine the type, severity, or stage of acid reflux in children and identify factors or indicators related to it, doctors may use additional examinations and procedures such as:
- Biopsy: During an upper GI endoscopy, a doctor may take a tissue sample (biopsy) from the esophagus or stomach to examine any issues more closely.
- 24-hour pH Monitoring: This test uses a thin tube placed in the esophagus for a full day to track acid levels, providing detailed information on acid patterns over time.
- Bravo wireless esophageal pH monitoring: A small capsule is placed in the esophagus during an endoscopy, which measures acid levels and sends data wirelessly to a receiver worn by the patient. This allows extended monitoring wirelessly without a nasal tube.
- Esophageal Manometry: This test measures muscle movements in the esophagus to check for any issues that might lead to acid reflux.
These exams and tests help doctors understand how severe a child’s acid reflux is and to create a treatment plan that fits their specific needs. If you think your child might have acid reflux, consulting a doctor is important for an accurate diagnosis and advice on managing the condition.
