The exact cause of diverticulitis is not known, but it is thought to be due to a combination of factors, including diet, age, smoking, obesity, physical inactivity and some medications.
The exact cause of diverticulitis is not fully understood, but several factors are thought to play a role.
One major factor is the formation of diverticula, which are small pouches that protrude through weak spots in the colon wall. These pouches develop over time due to increased pressure on the colon wall, often associated with a low-fiber diet. A low-fiber diet can lead to harder stools, requiring increased muscular contractions during bowel movements, which in turn increases pressure on the colon wall.
When diverticula become inflamed or infected, diverticulitis occurs. It is believed that food particles or bacteria can become trapped in the diverticula, leading to inflammation and infection. This can cause various symptoms and complications associated with diverticulitis.
Other factors that may contribute to diverticulitis:
- Diet: A low-fiber diet is a major risk factor for diverticulosis, which is the condition in which diverticula form in the colon. Fiber helps to keep stools soft and bulky, which makes it easier for them to pass through the colon. When stools are hard and small, they can put more pressure on the colon wall, which can weaken the wall and cause diverticula to form.
- Age: Diverticulosis is more common in people over the age of 40. This is thought to be because the colon wall becomes weaker with age.
- Smoking: Smoking increases the risk of diverticulosis and diverticulitis.
- Obesity: Obesity is a risk factor for diverticulosis and diverticulitis.
- Physical inactivity: Physical inactivity increases the risk of diverticulosis and diverticulitis.
- Certain medications: Some medications, such as steroids and nonsteroidal anti-inflammatory drugs (NSAIDs), can increase the risk of diverticulosis and diverticulitis.
It’s important to note that individual susceptibility to diverticulitis can vary, and not everyone with diverticula will develop diverticulitis. The interplay of these factors and the complex mechanisms underlying diverticulitis development are still subjects of ongoing research.
If you think you may have diverticulitis, talk things over with a doctor.
