"Heartburn" is not necessarily heartburn. Heartburn is a burning pain in the upper abdomen or lower chest, accompanied by acid reflux. Heartburn is one of the most common symptoms of the digestive system, often caused by people eating too fast or too much. However, for those with weak stomach and intestines, even if they pay great attention to diet, they often feel heartburn.
In addition, some people will have heartburn symptoms after eating certain foods, such as wine, chili, sweet potato, etc., because these foods can relax the lower esophageal sphincter or increase the gastric acid secretion, which will cause heartburn. For most people, especially young people, the symptoms of heartburn, even if very serious, happen occasionally or rarely repeatedly. Heartburn may be caused by gastric juice flowing back to the esophagus, resulting in a burning sensation in the chest. Because of the pressure of people's daily life and work, they are usually busy in the daytime and have little free time, so they make do with breakfast and lunch. Only in the evening can they have free time, so people often eat a delicious meal in the evening to reward their hard work for a day, while in the evening, they eat too much, too full (the pressure of stomach is relatively large), and live at night Less movement, plus the change of body position when sleeping at night, it is easy to cause the things in the stomach that are not fully digested to flow back into the esophagus with the gastric juice. Because the gastric acid has a corrosive stimulating effect on the esophagus, and then causes the inflammation of the esophagus, causing the patient to feel the same feeling of burning in the chest, people call it 'heartburn'.
Of course, there are also 'stomach fever' which causes' heartburn '. For example, obese people, or pregnant women, because the abdomen is large, it is easy to put the stomach in the upward position. But when these people have stomach inflammation, in order to return the acid and feel the hot feeling of the heart, people call this situation "heartburn".
