Old hiccups may be caused by gastritis, gastric ulcer and gastric cancer and other stomach diseases. 1. Gastritis: it is caused by inflammation of gastric mucosa. During the onset of gastritis, the stomach wall will become sensitive, and when stimulated, it will have abnormal spasm and contraction, which will stimulate the phrenic nerve to a certain extent, leading to the symptoms of hiccups in patients. 2. Gastric ulcer: it is caused by Helicobacter pylori infection, excessive secretion of gastric acid, long-term use of gastrointestinal stimulation drugs such as aspirin and other causes of gastric mucous membrane damage, which can lead to digestive dysfunction, and then lead to hiccups in patients. 3. Gastric cancer: it is due to the increasing expansion of stomach caused by the tumor, which invades the vagus nerve and leads to frequent hiccups. Note that frequent hiccups are not necessarily caused by gastric disease, but may also be caused by physiological factors such as eating too fast, position change, nerve stimulation and other diseases, such as esophagitis, pancreatitis and so on. It is recommended that the patient go to a professional hospital, under the guidance of a professional physician to identify the cause of the disease and treatment.
