There are many causes of stomach pain, and stomach pain is one of the most common symptoms in patients with gastric disease. Most of them are caused by local inflammation or stimulation of gastric acid at the site of the lesion, which causes spasm of smooth muscle of the stomach wall, increase of intragastric pressure and tension of muscle fibers, resulting in stimulation of nerve receptors at the site of the lesion, which leads to painful sensation and abdominal pain. Gastric neurosis is a disorder of the plant nervous system due to disorders of higher nerve activity, which leads to stomach discomfort. It is a dysfunction of the motor and secretory functions of the stomach, without histological organic lesions. The clinical manifestations are mainly gastrointestinal symptoms, which may be accompanied by other functional symptoms such as acid reflux, belching, nausea, vomiting, burning sensation under the glabella, fullness after eating, discomfort or pain in the upper abdomen, and may be accompanied by other common symptoms of neurosis such as lethargy, headache, palpitation, chest tightness, and apprehension. Gastroparesis itself is a symptom, not a disease. Gastric cramps are characterized by hysterical, neurological abdominal and chest provoking pain. Sometimes acute allergic reactions can also cause stomach cramps. About 90% of the so-called stomach cramps are not caused by the stomach itself, which does not feel painful. If pain occurs, this is most likely due to gallstone disease or other disorders, and this pain is very difficult to eliminate. The most common cause of stomach cramps is the irritation of food: cold, spicy and irritating, which tends to cause stomach cramps. In addition, mental factors also have a great impact on stomach cramps, some people have stomach pain when they get angry. This is the reason for this. Stomach cramps are also related to unhygienic food, bacterial infection, etc.
