Mucus in your stool can be alarming, but it’s often a temporary issue caused by minor digestive problems. While a little mucus is usually normal, excessive or persistent mucus can indicate an underlying health condition. This article will explore the common causes of mucus in stool.
Common Causes of Mucus in Stool
Several factors can contribute to the presence of mucus in your bowel movements. These include:
Food Poisoning
Certain foodborne illnesses, such as salmonella and shigella, can trigger diarrhea containing mucus and blood. Accompanying symptoms may include stomach cramps, fever, and vomiting. These infections inflame the intestines, leading to increased mucus production.
Bacterial Infections
Bacterial infections like C. diff, shigella, and salmonella can cause mucus in stool. Other culprits include campylobacter, often contracted from undercooked poultry or contaminated water, and Yersinia enterocolitica, linked to undercooked pork. These infections disrupt the gut’s natural balance, resulting in excess mucus.
Parasitic Infections
Intestinal parasites, such as protozoa and helminths, can lead to dysentery. This condition causes severe diarrhea with blood or mucus, accompanied by nausea, vomiting, fever, cramps, and weight loss. The parasites irritate the intestinal lining, prompting increased mucus production.
Colorectal Cancer and Polyps
Adenocarcinoma, the most common type of colorectal cancer, originates in the mucus-producing cells of the mucosa. Polyps, growths on the mucosa, can sometimes become cancerous. While excess mucus is rarely a sign of polyps or cancer, it’s crucial to discuss any concerns with your doctor. Other potential indicators include blood in stool and persistent changes in bowel habits. Regular colorectal cancer screenings are essential for early detection.
Anal Fistulas and Rectal Ulcers
Anal fistulas are infected tunnels connecting the skin and anus, often arising from abscesses or complications of inflammatory bowel disease (IBD). They can cause mucus, pus, and blood to drain. Rectal ulcers, open sores in the rectum lining, can also result in mucus or blood in stool.
When to See a Doctor
While occasional mucus in stool is usually harmless, consult a doctor if you experience:
- Persistent mucus in stool
- Bloody stool
- Severe abdominal pain
- Fever
- Unexplained weight loss
- Changes in bowel habits
Early diagnosis and treatment are essential for managing underlying conditions and ensuring optimal digestive health. Don’t hesitate to seek medical advice if you’re concerned about mucus in your stool.
