Stomach pain from eating cold food is caused by the stimulation of the mucous membrane of the gastrointestinal tract by food after the patient has eaten cold food, resulting in stomach pain due to gastrointestinal spasm. Patients who are prone to this condition have gastrointestinal disorders, such as ulcers and inflammation of the digestive tract. If the pain is in the upper abdomen it is a gastric disease, if the pain is located in the periumbilical area, it usually belongs to intestinal spasm and the patient should go to the hospital for a gastrointestinal endoscopy to clarify the condition and determine the final cause. If the digestive tract has mucosal lesions and ulcer inflammation, the patient’s gastrointestinal mucosa will be very fragile, and after being stimulated by external stimulation and cold stimulation, it will lead to peristaltic disturbance of the gastrointestinal tract, which will easily cause abdominal pain in response to spasm. If the patient’s stomach pain is accompanied by diarrhea, it may be due to acute gastroenteritis caused by bacteria in the food consumed. To sum up, if a patient has frequent stomach pain after eating cold food and the condition is repeatedly not significantly improved, he should go to the hospital for detailed examination to clarify the condition and treatment.
