Stomach cramping pain may be a precursor of gastric cancer, but acute gastritis, gastroduodenal obstruction and other gastric diseases may also cause stomach cramping pain. Patients are advised to actively consult a gastroenterologist for a clear diagnosis and treatment for the cause. Gastric cramps are muscle convulsions in the stomach, indicating that the stomach is in a state of strong contraction, mostly caused by abnormal nerve function, but also caused by organic diseases of the stomach, such as gastric cancer. Most patients with gastric cancer have no symptoms in the early stage, but some of them may have symptoms such as heartburn, belching and upper abdominal discomfort, and some of them may also have gastric spasm. It is recommended that patients should go to gastroenterology department for consultation after the symptoms appear, and after the cause of the disease is clear, they should be treated accordingly under the guidance of doctors to avoid delaying the disease. In addition, patients are advised to go to the hospital regularly for gastroscopy, especially for patients over 40 years of age, in order to clarify their physical condition and achieve early detection and treatment.
