Dr. Shen Yonghua
The presence of red mucus in the stool may be caused by various factors, mainly including:
1. Inflammatory conditions: such as bacterial dysentery, ulcerative colitis, etc. These diseases can cause damage to the gastrointestinal mucosa due to inflammation, leading to the appearance of red mucus.
2. Malignant tumors: such as colon cancer, rectal cancer, etc. Cancer cells invading the intestinal mucosa may cause bleeding, manifested as blood in the stool accompanied by red mucus.
3. Other conditions: rectal polyps, hemorrhoids, etc. may also cause rectal bleeding, where blood mixes with digestive fluids and food residue to form red mucus.
Dietary factors, such as excessive consumption of animal blood or blood-based processed foods, may also lead to a positive fecal occult blood test. If this symptom is observed, timely medical consultation and relevant examinations are recommended for accurate diagnosis and treatment.
