What is the main cause of diverticulitis?


Diverticulitis is a condition where small pockets or pouches called diverticula in the lining of the colon become inflamed or infected. The exact cause of diverticulitis is not fully understood, but it is thought to be related to a combination of factors, including:

  1. Increased pressure in the colon: When the colon is under strain to move stool through it, it can create pressure on the walls of the colon. This pressure can cause small pockets or pouches to form in the lining of the colon, which can then become inflamed or infected.
  2. Low-fiber diet: A diet that is low in fiber can cause constipation, which can also create pressure on the colon walls. Additionally, a low-fiber diet can lead to harder, smaller stools, which can also contribute to the development of diverticula.
  3. Aging: Diverticulitis is more common in older adults, and it is thought that the weakening of the colon walls that occurs with age may make it more susceptible to the formation of diverticula.
  4. Genetics: Some studies suggest that there may be a genetic component to the development of diverticulitis, although more research is needed to fully understand this link.

Other factors that may increase the risk of developing diverticulitis include obesity, smoking, lack of exercise, and certain medications.
