Routine stool examination shows blood.

In general, the presence of blood in a routine stool examination may be caused by factors such as hemorrhoids, chronic enteritis, or intestinal polyps. A detailed analysis is as follows:

1. Hemorrhoids

Unhealthy lifestyle habits or long-term consumption of spicy foods can lead to hemorrhoids, which may result in bleeding during bowel movements.

2. Chronic Enteritis

Chronic inflammation of the intestine can cause rupture of intestinal blood vessels, leading to blood being detected in a routine stool test.

3. Intestinal Polyps

Intestinal polyps are raised lesions on the intestinal mucosa; colloquially speaking, they are small fleshy growths on the intestinal lining. These can also cause bleeding that appears in routine stool examinations.

Besides the common causes mentioned above, other potential causes include inflammatory bowel disease, duodenal ulcers, colorectal cancer, and others. It is recommended to seek timely medical attention to avoid delaying treatment. In daily life, maintain a light diet and avoid spicy or irritating foods to prevent worsening of symptoms.
