The medical decision regarding whether to prescribe them depends on a careful assessment of the severity of the inflammation, the presence of complications, and the patient's general health condition. In mild and uncomplicated cases, physicians may rely solely on recommendations related to lifestyle, rest, and diet, while antibiotics remain a cornerstone of treatment in cases of severe inflammation or when the patient is at high risk of developing serious health complications [\[1\]](). ## Why have medical recommendations regarding antibiotics changed? In recent years, medical protocols have adopted a more conservative approach toward the use of antibiotics. The goal of this shift is to reduce unnecessary use of these medications, particularly in cases where there are no clear signs of severe infection or inflammation spreading beyond the colon wall. This approach contributes to minimizing drug side effects, such as digestive disturbances, and limits the risk of developing antibiotic-resistant bacteria. In simple cases of inflammation, the body may be able to manage localized inflammation on its own by providing rest to the colon through specific dietary measures, which in some cases eliminates the need for intensive pharmacological intervention [\[1\]](). ## When are antibiotics considered a medical necessity? The attending physician determines the need for antibiotics based on a thorough clinical examination and the results of diagnostic tests, such as a CT scan, which reveals the extent of the inflammation. Antibiotics are necessary in the following circumstances: - **Presence of structural complications:** If the inflammation leads to the formation of an abscess (pus collection), a perforation in the colon wall, or the formation of a fistula, antibiotic intervention becomes imperative to prevent the spread of infection [\[1\]](). - **Severe and persistent symptoms:** Patients who exhibit signs of systemic infection, such as persistent fever, chills, or severe pain that does not respond to simple painkillers, often require pharmacological treatment to control the bacterial infection [\[1\]](). - **Health risk factors:** Individuals with a weakened immune system or chronic health conditions that make them more susceptible to worsening infection may receive antibiotics as a preventive and therapeutic measure to reduce the chances of developing complications [\[1\]](). ## Managing uncomplicated cases: Diet and rest In cases where the physician determines that the diverticulitis is mild and does not require antibiotics, the focus is on resting the digestive system to allow the colon to recover. This often involves a short-term clear liquid diet to reduce bowel movements and decrease pressure on the inflamed pouches. As symptoms improve, solid foods are gradually reintroduced. It is essential to pay attention to the type of pain relievers used; doctors typically recommend "paracetamol" while avoiding non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, as they may increase the risk of complications in the colon [\[1\]](). To learn more about the available treatment options, you can review the article [Diverticulitis: Symptoms, Diet, Antibiotics, and Surgery (Arabic)](). ## When does the condition require a medical emergency? Although some cases can be treated at home, the appearance of certain signs requires urgent medical intervention, as they may indicate medical complications that necessitate hospital monitoring or surgical intervention. You should go to the emergency room if you experience: - Severe, sudden pain that worsens in the lower abdomen [\[1\]](). - A high fever with persistent chills [\[1\]](). - Severe nausea and vomiting that prevents the patient from drinking fluids, which may lead to dehydration. - Clear rectal bleeding or bloody stools [\[1\]](). - Inability to pass gas or stool, which may indicate an intestinal obstruction [\[3\]](). ## Medical references - [Diverticulosis and Diverticulitis]() - [Diverticular Disease]() General health education; not a substitute for individualized clinical assessment.
