What are the causes of abdominal pain and bloody stools?

Abdominal pain and bloody stools may be related to improper diet, bacterial dysentery, acute gastroenteritis, gastric ulcers, or intestinal polyps. It is important to seek timely medical evaluation at a hospital and follow medical advice for improvement through general management, medication, or surgical treatment as appropriate. Specific causes are analyzed as follows:

1. Improper diet: Consuming excessive spicy or cold foods, such as hot pot or ice cream, can easily damage the gastrointestinal mucosa, leading to symptoms such as abdominal pain and bloody stools. It is recommended to adjust the diet appropriately, avoid overconsumption of irritating foods, and maintain a light and balanced diet.

2. Bacterial dysentery: This condition is usually caused by Shigella infection, which may lead to ulcers in the rectum and colon, resulting in symptoms such as abdominal pain, diarrhea, and mucus-containing bloody stools. It is recommended to take medications such as Enteritis Ning Granules, Compound Berberine Tablets, or Belladonna Tablets under medical guidance to alleviate symptoms.

3. Acute gastroenteritis: This condition is commonly associated with overeating or bacterial infection. Inflammation can cause congestion and edema of the intestinal mucosa, which may bleed upon contact with stool, leading to abdominal pain and bloody stools. It is recommended to follow medical advice and use medications such as montmorillonite powder, cefixime granules, or amoxicillin capsules to improve symptoms.

4. Gastric ulcer: Gastric ulcers are often associated with Helicobacter pylori infection, certain medications, or high levels of psychological stress, and may cause symptoms such as abdominal pain and nausea. In severe cases, symptoms may include vomiting blood, black tarry stools (melena), and cold sweats. It is recommended to take proton pump inhibitors such as esomeprazole magnesium enteric-coated tablets, rabeprazole sodium enteric-coated tablets, or lansoprazole tablets as directed by a physician to manage the condition.

5. Intestinal polyps: These may result from genetic factors or chronic inflammation. Common symptoms include abdominal pain and bloating. Larger polyps may bleed due to friction with passing stool, causing bloody stools. When necessary, polyps can be surgically removed under medical supervision via procedures such as endoscopic polypectomy or endoscopic mucosal resection.

During treatment, patients should ensure adequate rest and avoid excessive fatigue to prevent undue strain on the body.
