Celiac gastritis usually does not cause diarrhea, which may be caused by a cold abdomen, intestinal flora imbalance, intestinal inflammation, intestinal malignant tumors and other reasons. Celiac gastritis usually manifests itself as epigastric discomfort, bloating, nausea, vomiting, belching (burping), loss of appetite, acid reflux, and other symptoms, and generally does not cause diarrhea. Diarrhea may be due to the following reasons: 1. Abdominal cold: not pay attention to abdominal warmth or eat cold food, resulting in abdominal cold caused by diarrhea. 2. Intestinal flora imbalance: more harmful bacteria in the intestines can lead to diarrhea, bloating, farting and so on. 3. Enteritis: Eating unhygienic food induces enteritis, which can lead to diarrhea, abdominal pain and other symptoms. 4. Intestinal malignant tumor: the infiltration of tumor cells into local tissues can cause diarrhea, discharge of mucus, pus and blood stools, anemia and other symptoms. It is recommended to consult a doctor in time to find out the cause of the disease and treat it as soon as possible so as to avoid delaying the disease.
