Pain from the stomach to the abdomen is mainly caused by acute gastroenteritis and indigestion. During the attack of acute gastroenteritis, the mucous membrane of the gastrointestinal system of the patient will not only appear congestion and edema due to the stimulation of inflammation, but will also be affected by the action of bacteria and cause gastrointestinal spasm resulting in pain, accompanied by nausea, diarrhea, abdominal distension and other manifestations. Patients with acute gastroenteritis can be improved by taking medications that protect the gastric mucosa, anti-inflammatory, and inhibit acid secretion, and avoiding irritating foods during medication. The digestive system will be affected during the attack of dyspepsia, resulting in peristaltic dysfunction of the gastrointestinal system, and the digestion process of food will be relatively longer, and the digestion process will cause stimulation of the mucous membrane of the gastrointestinal wall and produce a lot of gas, so the patient will show the symptoms of distension and pain in the digestive system.
