Can duodenal ulcers cause diarrhea?
If the patient's condition is mild, duodenal ulcers generally do not cause diarrhea; however, in more severe cases, diarrhea may occur. The detailed analysis is as follows:
1. No
Duodenal ulcer is a type of ulcerative disease primarily associated with Helicobacter pylori infection. If patients frequently engage in heavy physical labor, leading to significant fatigue, or consume coarse foods that impair gastric defense mechanisms, Helicobacter pylori may invade and trigger duodenal ulcers. Inflammatory factors continuously stimulate surrounding nerves, causing abdominal pain, which typically improves after eating. Diarrhea usually does not occur in such cases.
2. Yes
If the patient’s condition is more severe, persistent spread of inflammatory factors may disrupt intestinal microbiota balance. After eating, the intestinal contents cannot be properly broken down, resulting in malabsorption of proteins and fats. This alters stool characteristics and leads to diarrhea. Patients are advised to take medications such as aluminum phosphate gel or almagate suspension under medical supervision.
Patients should maintain healthy dietary habits, ensure balanced nutrition, keep emotions stable, and avoid smoking and alcohol consumption to promote recovery. If severe diarrhea occurs, prompt medical attention is essential.
