Heartburn is a burning sensation in the upper abdomen or lower chest, accompanied by symptoms of gastric acid reflux. Heartburn is one of the most common symptoms of digestive system. For most people, the most common reason is eating too fast or too much. However, even if some people pay great attention to their diet, they often get heartburn. Some people get heartburn after eating certain foods, such as wine and pepper. These foods can relax your lower esophageal sphincter or increase gastric acid secretion, which can lead to heartburn.

For most people, especially young people, the symptoms of heartburn may be very serious, but they are often short-lived and rarely recur. For many elderly people, because of the decline of digestive system function, even if they are very careful, the symptoms of heartburn will often accompany them. Cold weather, slightly cold food and indigestible food can all cause symptoms of heartburn.
