If the patient has been gurgling inside the stomach, if this symptom appears after drinking milk or soy milk, it is mostly considered that milk and soy milk contain fermentable gas-producing ingredients, which will lead to this symptom in the stomach and intestines, which is a normal phenomenon and can be left untreated. If the patient has abdominal distension and abdominal pain in addition to rumbling inside the stomach, functional gastrointestinal disease or intestinal obstruction will be considered, and the latter will often show that exhaustion has stopped for more than a day. After excluding the intestinal obstruction, it can be considered as functional gastrointestinal disease, which needs to be treated with drugs such as trimebutine maleate plus rectified intestine or pefixan to induce bowel movement or exhaustion. The diet should temporarily refrain from drinking milk, soy milk and other easily fermented foods, pay attention to keeping the abdomen warm, and temporarily refrain from drinking alcohol.
