What causes mucus in stool and what should I do?

Symptom Database

Mucus in stool can be a concerning symptom that may indicate an underlying health issue. While it is normal to have a small amount of mucus in your stool, an excessive amount or persistent presence of mucus can be a cause for concern. In this article, we will explore the causes of mucus in stool, its symptoms, and the available treatment options.

Causes of Mucus in Stool

There are several potential causes of mucus in stool, ranging from minor conditions to more serious underlying health problems. Some common causes include:

  • Intestinal infections: Infections caused by bacteria, viruses, or parasites can lead to increased mucus production in the intestines.
  • Inflammatory bowel disease (IBD): Conditions such as Crohn’s disease and ulcerative colitis can cause chronic inflammation in the digestive tract, leading to mucus in stool.
  • Food intolerances: Certain food intolerances, such as lactose intolerance or gluten sensitivity, can cause mucus in stool.
  • Colon polyps: These are growths that develop on the inner lining of the colon and can sometimes cause mucus in stool.
  • Colon cancer: While less common, colon cancer can cause mucus in stool, along with other symptoms such as blood in the stool and unexplained weight loss.

Symptoms of Mucus in Stool

In addition to the presence of mucus in stool, there may be other accompanying symptoms that can provide further insight into the underlying cause. Some common symptoms include:

  • Diarrhea or loose stools
  • Abdominal pain or cramping
  • Bloating or gas
  • Changes in bowel habits
  • Blood in the stool
  • Unexplained weight loss

If you experience any of these symptoms along with mucus in your stool, it is important to consult a healthcare professional for a proper diagnosis and appropriate treatment.

What Does Mucus in Stool Mean?

The presence of mucus in stool can indicate various underlying conditions, and its meaning can vary depending on the individual and their specific symptoms. It is essential to consider other factors such as the frequency, consistency, and color of the stool, as well as any accompanying symptoms.

In some cases, mucus in stool may be a temporary and harmless occurrence, such as when it is caused by a mild gastrointestinal infection. However, if the mucus persists or is accompanied by concerning symptoms, it may indicate a more serious condition that requires medical attention.

Treatment for Mucus in Stool

The treatment for mucus in stool depends on the underlying cause. In some cases, simple lifestyle changes and home remedies may be sufficient to alleviate the symptoms. However, for more severe or chronic conditions, medical intervention may be necessary.

Home Remedies and Lifestyle Changes

If the mucus in stool is caused by a minor condition or temporary irritation, the following home remedies and lifestyle changes may help:

  • Stay hydrated: Drinking plenty of water can help soften the stool and reduce mucus production.
  • Dietary modifications: Avoiding trigger foods or following a specific diet recommended by a healthcare professional can help manage symptoms.
  • Probiotics: Taking probiotic supplements or consuming probiotic-rich foods may help restore the balance of gut bacteria.
  • Stress management: Stress can worsen digestive symptoms, so finding effective stress management techniques can be beneficial.

Medical Interventions

If the mucus in stool is persistent or accompanied by more severe symptoms, medical interventions may be necessary. These can include:

  • Antibiotics: If an infection is causing the mucus, antibiotics may be prescribed to eliminate the underlying bacteria.
  • Anti-inflammatory medications: In cases of inflammatory bowel disease, medications such as corticosteroids or immunosuppressants may be prescribed to reduce inflammation.
  • Surgery: In certain cases, such as colon polyps or cancer, surgical intervention may be required to remove the growth or affected portion of the colon.

It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan tailored to your specific condition.


Mucus in stool can be a concerning symptom that may indicate an underlying health issue. While it is important to be aware of this symptom and seek medical attention if necessary, it is also essential to consider other factors such as accompanying symptoms and changes in bowel habits. By understanding the potential causes, symptoms, and available treatment options, individuals can take proactive steps towards managing their health and seeking appropriate care when needed.
