What is the first line treatment for uncomplicated diverticulitis?

The first-line treatment for uncomplicated diverticulitis is conservative management with antibiotics. In the case of uncomplicated diverticulitis, which typically presents with mild symptoms, the approach primarily focuses on symptom relief and elimination of the infection while allowing the colon to heal.

Antibiotics play a key role in addressing the underlying infection that can occur with diverticulitis. By using antibiotics, the inflammation can be reduced, leading to symptom improvement. Additionally, conservative management may include dietary changes, typically a low-fiber diet immediately after diagnosis transitioning to a high-fiber diet once symptoms improve, as fiber helps to decrease the risk of recurrences and complications.

Surgical intervention is generally reserved for complicated cases of diverticulitis, such as abscess formation, perforation, or recurrent episodes. Dietary modification alone, while important for long-term management, does not address the acute infection associated with the initial episode of diverticulitis. Intravenous fluid therapy may be needed in cases of severe symptoms or inability to tolerate oral intake but is not a standard first-line treatment for uncomplicated cases.

Thus, the use of antibiotics as part of the conservative management strategy is essential for treating uncomplicated diverticulitis effectively and safely.
