What is the most common age group affected by diverticulitis?

Diverticulitis is primarily a condition that affects adults, particularly those aged 50 to 70. This age group is more prone to developing diverticular disease due to age-related changes in the colon, including muscle weakening and changes in colonic pressure dynamics. The prevalence increases with age, as diverticulosis, the precursor to diverticulitis, often develops silently prior to inflammation or infection. Consequently, by the time individuals reach their 50s and beyond, many may have diverticular disease, increasing the likelihood of diverticulitis as they age further.

While diverticulitis can occur in younger adults, it is considerably less common compared to older adults. Children and younger adults generally have lower rates of gastrointestinal disorders like diverticulitis. Thus, the 50 to 70 age range reflects the demographics most affected by this condition, making it the most accurate choice.
