What causes stomach pain, diarrhea, and bloody stools?

In general, stomach pain accompanied by diarrhea and bloody stools may be caused by conditions such as gastritis, gastric ulcer, or duodenal ulcer. The details are as follows.

1. Gastritis

Gastritis refers to inflammation of the gastric mucosa. Common symptoms include nausea, vomiting, stomach pain, and indigestion. Inflammatory secretions may irritate the intestinal lining, leading to bleeding of the intestinal mucosa. Under a doctor's guidance, patients may use medications such as omeprazole enteric-coated capsules, rabeprazole sodium enteric-coated capsules, and Yunnan Baiyao for treatment.

2. Gastric Ulcer

Gastric ulcer is a common stomach condition. If the ulcer penetrates the stomach wall and causes perforation, it may lead to intra-abdominal bleeding, resulting in blood in the stool. Under medical supervision, patients may be treated with medications such as potassium citrate bismuth tablets, omeprazole enteric-coated tablets, and injectable omeprazole sodium.

3. Duodenal Ulcer

Duodenal ulcer is a lesion occurring in the mucosal or submucosal layer of the duodenum that leads to local mucosal defects. If the condition worsens and irritates the intestinal mucosa, capillaries may rupture, causing abnormal bowel movements and bloody stools. In severe cases, surgical repair of duodenal perforation may be required.

Besides the above causes, similar symptoms may also result from enteritis, colitis, cholecystitis, biliary ascariasis, liver cirrhosis, and other conditions. It is important to maintain proper dietary habits, avoiding spicy and irritating foods such as chili peppers and ginger. Eating light, easily digestible foods like millet porridge and noodles can aid in recovery.
