Can Diverticula Cause Constipation?

Diverticula are common small pouches that can form in the lining of the digestive tract. Many individuals wonder about the connection between these pouches and the digestive issue of constipation. Understanding this relationship is important for those experiencing discomfort or changes in bowel habits. This article explores how diverticula develop and their potential association with constipation.

Understanding Diverticula

These small, bulging pouches develop most frequently in the large intestine or colon. They form when increased pressure within the colon pushes the inner lining through naturally weak spots in the muscular wall. Diverticula are quite common, especially as people age; over half of individuals in the United States over 60 years old have diverticulosis.

The presence of these pouches is known as diverticulosis, which often causes no symptoms and may go undetected. However, if one or more of these diverticula become inflamed or infected, the condition is then termed diverticulitis. Diverticulitis can lead to more noticeable symptoms and complications. While diverticulosis itself is not considered a disease, diverticulitis indicates an active inflammatory process.

The Link to Constipation

The relationship between diverticula and constipation is complex, involving both cause and effect. Chronic constipation has long been considered a contributing factor to the development of diverticula. The increased pressure and straining during difficult bowel movements can force the colon’s inner lining through weak points, leading to pouch formation.

While constipation can promote the formation of diverticula, the reverse relationship—whether diverticula directly cause constipation—is less straightforward. Some individuals with diverticulosis do experience constipation, along with other symptoms like mild cramps or bloating. However, current research suggests that constipation is not a direct cause of diverticulitis, and some studies even indicate an inverse relationship between low bowel movement frequency and diverticulosis.

The presence of diverticula, especially when inflamed during diverticulitis, can indirectly affect bowel function. Inflammation can alter gut motility and lead to symptoms such as constipation, diarrhea, or changes in stool habits. In chronic diverticulitis, persistent inflammation and scarring can potentially lead to a bowel obstruction, which may cause constipation, thin stools, and abdominal pain. While constipation might be a symptom for some with diverticulosis or diverticulitis, it is not universally experienced; others report diarrhea or no bowel changes.

Managing Diverticula and Bowel Health

Managing diverticula and promoting regular bowel movements involves lifestyle and dietary adjustments. A diet rich in fiber plays a central role, as fiber adds bulk to stool and helps it pass more easily, thereby reducing pressure in the colon and potentially preventing further diverticula formation. High-fiber foods include whole grains, fruits, vegetables, beans, and legumes. Gradual increases in fiber intake are recommended to avoid bloating and discomfort.

Adequate fluid intake is also important, as water helps to soften stools and supports the effectiveness of dietary fiber in preventing constipation. Regular physical activity further contributes to bowel health by promoting normal bowel movements and reducing the risk of constipation.

When to Seek Medical Advice

Consult a healthcare professional for an accurate diagnosis and personalized management plan if you suspect diverticula or experience persistent bowel issues. Certain symptoms warrant immediate medical attention to prevent serious complications. These include severe, constant abdominal pain, especially on the lower left side, which might intensify over several days.

Other concerning signs are a high temperature or fever, chills, persistent nausea or vomiting, and noticeable blood in your stool. Any sudden or significant changes in bowel habits that are new or worsening should also prompt a medical evaluation. Self-diagnosis and self-treatment are not recommended, as symptoms of diverticular disease can overlap with other conditions, requiring professional assessment.
