GERD
GERD or gastroesophageal reflux disease is a common digestive issue. Although it does not actually cause postnasal drip, the condition can mimic the symptom and lead to misdiagnosis. In addition, there are other possible symptoms, such as abdominal pain, chest discomfort, or heartburn. To diagnose GERD, direct laryngoscopy is needed. The result can indicate irritation in your upper throat due to stomach acid. Esophagogastroduodenoscopy and a 24-hour pH probe are other diagnostic options. If left untreated, GERD can lead to serious complications over time. [4]
