Mucus in stool is a common occurrence and can be caused by various factors ranging from minor irritations to more serious medical conditions. Mucus is normally produced by the intestines to keep the lining moist and protect it, but excess mucus in stool can occur due to inflammation, infections, or irritation.
Common Causes
- Minor intestinal irritation caused by certain foods, dehydration, or lack of fiber.
- Food allergies or intolerances (e.g., lactose, gluten).
- Infections of the digestive tract by bacteria, viruses, or parasites.
- Hemorrhoids or anal fissures causing mucus discharge.
Medical Conditions
- Inflammatory bowel diseases (IBD) such as Crohn’s disease and ulcerative colitis where the intestines are chronically inflamed.
- Irritable bowel syndrome (IBS), a functional disorder causing mucus production with symptoms like cramping, diarrhea, or constipation.
- Proctitis, an inflammation of the rectum lining.
- Colorectal cancer in rare cases, especially if mucus is accompanied by bleeding, pain, or unexplained weight loss.
When to Seek Medical Help
- If mucus is accompanied by blood, abdominal pain, fever, diarrhea, or significant changes in bowel habits.
- If there is sudden weight loss or family history of colorectal cancer.
- Persistent or worsening symptoms require consultation with a healthcare professional for testing and treatment.
In summary, occasional mucus in stool can be normal, but frequent or large amounts especially with other symptoms may indicate an underlying health issue that needs evaluation.
