What common lifestyle factor can precipitate flare-ups of diverticulitis?

Smoking is recognized as a common lifestyle factor that can precipitate flare-ups of diverticulitis. Smoking has been shown in various studies to be associated with an increased risk of diverticular disease and its complications. The inflammatory process that smoking promotes can exacerbate gastrointestinal conditions, contributing to episodes of diverticulitis. Moreover, smoking can lead to decreased blood flow to the colon and promote changes in the gut microbiome, both of which may play a role in the development and worsening of diverticular disease.

In contrast, a high-fiber diet is generally recommended to prevent diverticulitis and its flare-ups because fiber helps to maintain bowel regularity and decreases intracolonic pressure. Excessive hydration is beneficial for overall digestion and does not contribute to diverticulitis flare-ups. Regular exercise is also favorable for gastrointestinal health and can help prevent diverticular diseases by promoting regular bowel movements. Thus, smoking stands out as a lifestyle factor that directly contributes to the exacerbation of diverticulitis.
