The most typical symptoms of gastroesophageal reflux are also the most familiar symptoms, probably many people have experienced acid reflux and heartburn these two symptoms, as follows: 1. Acid reflux: is the feeling of acid gushing upward from behind the sternum. Acid reflux upward can reach behind the sternum, can reach the throat, can also reach the mouth, some people can even a mouthful of acid can gush to the nasal cavity, will gush to this throat choking, gushing up is acid; another acid reflux relative is anti-food, is anti up is undigested food or mucus, and of course there is anti-gas is burping, burping is also a very common symptom; 2, heartburn: heartburn In fact, as the name implies, it is a burning sensation behind the sternum and under the raphe. Heartburn is actually more widespread and can reach the throat and also the upper abdomen, so heartburn can range from the upper abdomen all the way to the bottom of the throat, and any burning sensation can be called heartburn. There is a difference between the two symptoms of heartburn and acid reflux. Heartburn is more of a sensory nature, while acid reflux and reflux against food can reach the liquid or gas in the mouth, which is an objective condition. So heartburn is relatively subjective and acid reflux and regurgitation are relatively objective. For most patients with GERD, acid reflux and heartburn symptoms are usually present and can be absent in a few patients. If there are typical symptoms of acid reflux and heartburn, they can be used more easily to diagnose GERD. If there are no symptoms of acid reflux and heartburn, we are going to need to further diagnose with other tests and evaluations.
