Diverticulosis is a condition where small, bulging pouches (diverticula) develop in the lining of the digestive system, usually in the colon. The exact causes of diverticulosis are not fully understood, but there are two main theories:
- Weakness in the colon wall: One theory is that diverticula form due to weakness in the muscular wall of the colon. As people age, the colon wall may weaken, and pressure from within the colon can push out pockets or pouches in the lining.
- Low-fiber diet: Another theory is that a low-fiber diet is a major contributor to the development of diverticulosis. A diet low in fiber can cause constipation, which increases the pressure inside the colon and makes it harder to pass stool. Over time, the increased pressure can lead to the formation of diverticula.
It’s important to note that while these are the two main theories behind diverticulosis, there are likely other factors involved in the development of this condition, such as genetics and lifestyle factors.
