What is the primary purpose of a pH probe in diagnosing gastroesophageal reflux (GERD)?

• A. To measure alkaline levels of reflux
• B. To measure acidity over a 24-hour period
• C. To evaluate event of vomiting
• D. To assess swallowing reflex

Answer: (B)

The primary purpose of a pH probe in diagnosing gastroesophageal reflux disease (GERD) is to measure acidity over a 24-hour period. This procedure provides valuable information about the frequency and duration of acid exposure in the esophagus, which is crucial in diagnosing GERD. During the test, a thin tube with a sensor is placed in the esophagus, and it continuously monitors pH levels. Understanding the acidity levels helps health professionals identify whether reflux episodes are occurring and whether they are associated with the symptoms experienced by the patient. A higher frequency of acidic reflux can indicate GERD, allowing for more effective treatment options to be explored. Other methods mentioned may have roles in gastrointestinal assessments but do not specifically focus on measuring the acid levels associated with GERD. For instance, evaluating the event of vomiting or assessing the swallowing reflex are important for different clinical considerations but do not directly correlate with the diagnosis and management of gastroesophageal reflux in the way that pH monitoring does.
