The symptoms of esophageal reflux are varied, the most typical of which is acid reflux, which is called acid swallowing in traditional Chinese medicine. This symptom is not only food regurgitation, but in severe cases, it can even cause the newly eaten food to flow backwards. This condition mostly occurs during nighttime sleep because when you lie flat, the contents of the stomach are prone to reflux due to the reduced position.
Esophageal reflux may also cause discomfort such as heartburn, chest tightness, chest pain, and even a foreign body sensation in the throat in some patients. If you look closely, you will see that this is sometimes associated with pharyngitis in the throat. Sometimes, coughing can be mistaken for chronic bronchitis, but it can actually be caused by esophageal reflux. This is because acid reflux irritates the bronchial tubes, which triggers a cough.
In addition, there may be fullness, dull pain in the stomach, and even back pain and chest pain in severe cases. Pain may also occur around the navel, in the left upper quadrant, or in the right upper quadrant. Overall, symptoms of esophageal reflux include acid reflux, heartburn, sore throat, and a foreign body sensation, as well as nausea, belching, and hiccups, among others.
