What Are the Causes of Diverticulosis and Diverticulitis?

Causes of Diverticulosis and Diverticulitis

Diverticulosis and diverticulitis are conditions related to the formation and inflammation of diverticula, which are small bulging pouches that can form in the lining of the digestive system. Understanding the causes of these conditions is crucial for prevention and management.

Causes of Diverticulosis

Diverticulosis is primarily caused by increased pressure within the colon, which leads to the formation of diverticula. Factors contributing to this increased pressure include a low-fiber diet, which results in harder stools and increased straining during bowel movements. This straining can cause weak spots in the colon wall to bulge out, forming diverticula.

Causes of Diverticulitis

Diverticulitis occurs when one or more diverticula become inflamed or infected. The main cause of acute diverticulitis is the abnormal accumulation of fecal bacteria within the diverticular lumen. This imbalance between normal probiotic microflora and pathogenic species, such as Gram-negative Enterobacteriaceae, including Escherichia coli and Proteus spp, leads to inflammation and infection. These bacteria have the ability to adhere to the intestinal mucosa, triggering the disease-related symptoms1.

Immune Response and Inflammation

The intestine, being the largest human lymphoepithelial organ, plays a significant role in immune response. It produces more antibodies, mainly secretory IgAs, than all other lymphoid tissues combined. These IgAs have various immune and anti-inflammatory properties that help in maintaining a balance between beneficial and harmful bacteria. An imbalance in this immune response can contribute to the development of diverticulitis1.

Conclusion

Diverticulosis is primarily caused by increased pressure in the colon due to a low-fiber diet, while diverticulitis results from bacterial infection and inflammation of the diverticula. Understanding these causes can aid in the prevention and management of these conditions, highlighting the importance of dietary fiber and maintaining a healthy gut microbiome.
