What are diverticula?

Diverticula are small pouches that can form in the lining of the colon, specifically in areas where the muscle layer of the colon is weakened. This can occur due to increased pressure inside the colon, typically related to dietary factors, such as low fiber intake, which leads to constipation. As the intestines contract to push stool through, these weak spots can bulge out and result in the formation of diverticula.

The presence of diverticula is commonly associated with a condition known as diverticulosis, where many of these pouches form, often without causing symptoms. However, if diverticula become inflamed or infected, this can lead to diverticulitis, which can involve abdominal pain, fever, and changes in bowel habits. Understanding the nature of diverticula is critical in recognizing their potential health implications.
