The possibility of intestinal spasm is more likely, especially if the patient is accompanied by fever, nausea and other symptoms of gastrointestinal irritation, which also need to be further combined with abdominal ultrasound, standing abdominal plain film and other related examinations. In the summer and autumn, the prevalence of gastroenteritis is related to diet, and the patient may also have diarrhea. Severe diarrhea can lead to fluid loss and imbalance of the internal environment, and intravenous fluid supplementation and anti-infective treatment are needed if necessary. Other patients are suffering from occupational lesions of the intestinal tract, which are chronic in course and are associated with abnormal bowel movements, including black stools, or unformed stools, as well as significant loss of appetite and weight loss, and if necessary, further examination with colonoscopy or abdominal CT.
