Symptoms of acid reflux include acid reflux, heartburn, and throat discomfort. 1. Acid reflux: Acid reflux usually manifests itself as an obvious burning sensation in the upper chest, and in severe cases, it can reflux into the mouth. Generally speaking, people who have smoking habit and like to eat salty food are more likely to have GERD. 2. Heartburn: Some patients with severe acid reflux may experience heartburn and nausea, which is often mistaken for heart disease. At the same time, such patients may also experience weakness, chest tightness or even fainting. Therefore, we must pay attention to eat on time, especially for patients with poor stomach and intestines, it is more important to eat on time, do not be overly hungry, but on time and in quantitative terms. 3. Throat discomfort: It is an atypical symptom of acid reflux, mainly because stomach acid refluxes into the mouth through the esophagus in the process of stimulating the throat, which will cause throat discomfort over time. In your daily life, try not to choose to eat late at night, or exercise and work immediately after meals. Smoking can easily cause acid reflux, so quit smoking and drinking. In addition, sleeping with a pillow can also prevent acid reflux. When obvious discomfort occurs, active consultation and treatment are needed.
