Collagenous and Lymphocytic Colitis

Collagenous and lymphocytic colitis are types of inflammatory bowel disease that can cause chronic discomfort and disruption to your daily life. At North Shore Gastroenterology, our team provides expert diagnosis and personalized management for these conditions.

What are Collagenous and Lymphocytic Colitis?

Collagenous colitis and lymphocytic colitis are the two primary forms of a condition known as microscopic colitis. Unlike other forms of inflammatory bowel disease, where inflammation is visible during a colonoscopy, the lining of the colon in microscopic colitis appears normal to the naked eye. The inflammation can only be seen when tissue samples are examined under a microscope.

While the symptoms are similar, the two types are distinguished by their appearance under a microscope:

There is an accumulation of lymphocytes (white blood cells) within the lining of the colon.

A thick layer of collagen (a structural protein) forms under the lining of the colon.

Both conditions prevent the colon from absorbing enough fluid, leading to chronic watery diarrhea. While they are not life-threatening and do not increase the risk of colon cancer, they can significantly impact your quality of life.

Causes and Risk Factors

The exact cause of microscopic colitis is not fully understood, but it is believed to be an immune response to a trigger.

Potential causes and risk factors include:

  • Medications: Certain drugs are strongly linked to the development of these conditions, including non-steroidal anti-inflammatory drugs (NSAIDs like aspirin and ibuprofen), proton pump inhibitors (PPIs), and certain antidepressants (SSRIs).
  • Autoimmune Conditions: People with other autoimmune disorders, such as celiac disease, thyroid disease, or rheumatoid arthritis, are at higher risk.
  • Age and Gender: These conditions are most common in people aged 50 and older, and women are significantly more likely to be affected than men.
  • Smoking: Research suggests a link between cigarette smoking and an increased risk of colitis.
  • Infections: Bacterial or viral infections of the gastrointestinal tract may trigger the condition.

Symptoms of Collagenous and Lymphocytic Colitis

The hallmark symptom of both collagenous and lymphocytic colitis is chronic, non-bloody, watery diarrhea. Symptoms can be continuous or intermittent, with periods of improvement followed by flare-ups.

Common symptoms include:

  • Chronic Watery Diarrhea: This is the most consistent symptom and can occur multiple times a day.
  • Abdominal Pain and Cramping: Discomfort in the belly is common.
  • Weight Loss: Unintentional weight loss may occur due to fluid loss and poor absorption.
  • Nausea: Feeling sick to your stomach.
  • Dehydration: Losing too much fluid through diarrhea can lead to dehydration.
  • Fatigue: Feeling unusually tired or weak.
  • Fecal Incontinence: Difficulty controlling bowel movements due to urgency.

Diagnosing Collagenous and Lymphocytic Colitis

Diagnosing these conditions requires a specific approach because standard imaging and visual exams often look normal.

The diagnostic process typically involves:

Symptoms, lifestyle, and medication use are discussed to identify potential triggers.

To rule out infection or other causes of diarrhea.

This is the definitive test. Since the colon looks normal visually, the doctor must take small tissue samples (biopsies) from different parts of the colon. These samples are analyzed by a pathologist to look for the characteristic signs of increased lymphocytes or collagen thickening.

Treatment Options

The goal of treatment is to stop the diarrhea and improve your quality of life. In many cases, symptoms can be managed effectively with medication adjustments and lifestyle changes.

Treatment strategies include:

If a medication is suspected to be the cause, it may be recommended to stop or switch that drug.

A diet low in fat and fiber, and avoiding caffeine, alcohol, and dairy products, which can worsen symptoms, may be recommended.

Over-the-counter or prescription medications can help control bowel movements.

Medications like budesonide are often prescribed to reduce inflammation in the colon. This specific steroid is released in the gut, minimizing side effects compared to systemic steroids.

In rare, severe cases that do not respond to other treatments, medications to suppress the immune system may be used.
