A burst of pain in the stomach is paroxysmal pain in the abdomen, which may be related to cold, gastroenteritis, intestinal obstruction and other reasons. 1. Cold: when the abdomen is cold, the gastrointestinal contraction and peristalsis will be accelerated, which will easily cause intestinal spasm, and the symptom of abdominal paroxysm will appear. 2. Gastroenteritis: after eating unclean food, or overeating, it will increase the burden on the gastrointestinal tract and lead to inflammatory reaction in the gastrointestinal tract, which will lead to paroxysmal pain in the abdomen when the inflammation stimulates the intestinal tract. 3. Intestinal obstruction: it is caused by the obstruction of intestinal contents when passing through, mostly manifested as paroxysmal abdominal cramps, accompanied by abdominal distension, vomiting, and inability to defecate and urinate, etc. The causes of paroxysmal abdominal pain are more complicated. There are many causes of abdominal cramps, which need to be combined with the cause of the disease and other symptoms to make a diagnosis. It is recommended to consult a doctor and undergo relevant tests to identify the cause of the pain and to treat it under the doctor’s guidance.
