There are no three clinical tricks to determine whether it is stomach cramps. In general, you can determine whether it is stomach cramps by observing the symptoms of the disease, physical examination, gastroscopy and other ways. 1. Symptoms of the disease: When a patient with stomach cramps has an attack of the disease, the epigastric region may experience pinprick-like paroxysmal pain as well as a feeling of constriction. If the situation is serious, the patient’s left shoulder blade, left chest and other parts of the body may also experience pain. 2. Physical examination: patients with stomach cramps may have tense upper abdominal muscles and increased bowel sounds. During the examination, the patient’s umbilicus may also be found to have a feeling of pressure and pain in the upper part of the umbilicus. 3. Gastroscopy: Gastroscopy in patients with gastroparesis shows normal gastric mucosa if the disease has not attacked; if the disease has attacked, the folds of the gastric mucosa can be observed to increase and thicken without edema. When it is suspected that the discomfort is caused by gastroparesis, it is recommended that the patient go to the hospital for examination and treatment in time.
