Younger people are also admitted to a hospital if they get diverticulitis than older people.

According to a review of research issued in 2018, different risk factors of diverticulitis include:

Family history

Research has discovered those genetics also responsible for diverticular disease, with some reports estimating that nearly 40-50% of the possible risk of diverticular disease is hereditary.

Low levels of vitamin D

Some studies recommend that people with more vitamin D might get a lower risk of having diverticulitis. More research is required to know the possible link between diverticula and vitamin D.


Different studies have found that people with more BMI and more waists are at high risk of diverticulitis by changing the bacteria balance in the gut, but more research is needed to know the role this plays.

Physical Inactivity

Some studies have discovered that physically active people are less likely than inactive people to grow diverticulitis. However, this link needs extra research.


Using smoking or nonsteroidal drugs (anti-inflammatory) (NSAIDs) or

A common use of aspirin, NSAIDs, or ibuprofen may increase the risk of diverticulitis. People who smoke also have more possibilities than non-smokers to increase diverticular disease.
