Diverticulitis Overview

Diverticulitis is the inflammation or infection of small bulging pouches, called diverticula that form in the wall of the colon. These pouches themselves are usually harmless, but when they become inflamed, they can cause significant digestive issues. Diverticulitis is not caused by infection alone, but risk factors include aging, a low-fiber diet, chronic constipation, obesity, and certain lifestyle factors. It can occur at any age but is more common in adults over 40.

The primary symptoms of diverticulitis include sudden lower abdominal pain, often on the left side, fever, nausea, vomiting, and changes in bowel habits such as constipation or diarrhea. In severe cases, complications may develop, including abscess formation, perforation of the colon, fistula, or peritonitis, which can require urgent medical intervention or surgery.

Diverticulitis Diagnosis and Treatment Algorithm

Diagnosing diverticulitis can be challenging due to symptom overlap with other abdominal conditions such as appendicitis, irritable bowel syndrome, or inflammatory bowel disease. Clinicians rely on a combination of clinical signs, including sudden onset of abdominal pain (often in the lower left quadrant), fever, nausea, and changes in bowel habits, along with patient history and known risk factors like age, low-fiber diet, and prior diverticular disease.

Laboratory tests, including elevated white blood cell counts and inflammatory markers like C-reactive protein (CRP), can support the diagnosis but are not specific. Imaging studies, particularly abdominal Computed Tomography (CT) scans, remain the gold standard for confirming diverticulitis, assessing severity, and detecting complications such as abscesses or perforation. Ultrasound or MRI may serve as alternatives when CT is unsuitable. Clinical scoring systems and careful evaluation of risk factors help guide testing, enabling faster, more accurate diagnosis and appropriate management decisions.

Treatment of diverticulitis focuses on controlling inflammation, managing infection, and preventing complications or recurrence. Initial therapy typically involves oral or intravenous antibiotics for mild to moderate cases, with hospitalization, bowel rest, or surgical intervention reserved for severe or complicated cases such as abscess, perforation, or peritonitis. The choice and duration of therapy depend on disease severity, patient comorbidities, and risk of recurrence. Ongoing monitoring, patient education on diet and lifestyle modifications, and timely follow-up are essential to reduce complications, detect recurrence early, and optimize long-term outcomes.

Diverticulitis Epidemiology

The epidemiology section of the diverticulitis market report offers information on the patient populations, including historical and projected trends for each of the seven major markets. Examining key opinion leader views from physicians or clinical experts can assist in identifying the reasons behind historical and projected trends. The diagnosed patient pool, their trends, and the underlying assumptions are all included in this section of the report.

This section also presents the data with relevant tables and graphs, offering a clear and concise view of the incidence of diverticulitis. Additionally, the report discloses the assumptions made during the analysis, ensuring data interpretation and presentation transparency. This epidemiological data is valuable for understanding the disease burden and its impact on the patient population across various regions.

Key Findings

Based on secondary analysis, diverticulitis in the US demonstrates a gender disparity, affecting approximately 58% of females and 42% of males, highlighting a slightly higher burden among women and suggesting potential differences in risk factors, lifestyle, or disease presentation between genders.

In France, diverticulitis shows a marked age-related pattern, with nearly 88% of cases occurring in individuals aged 60 or above, compared to 12% in those aged below 60 years old, highlighting a substantially higher burden among the elderly population.

In Italy, diverticulitis accounts for approximately 19,000 incident cases annually, reflecting a significant clinical burden and underscoring the need for improved awareness, timely diagnosis, and effective management strategies.

In Japan, diverticulitis demonstrates a distinct site-specific distribution, with 10.9% of cases occurring in the left colon compared to 2.8% in the right colon, reflecting a shift toward left-sided disease and suggesting potential variations in risk factors, diet, or age-related colon changes within the population.

The epidemiology of diverticulitis is expected to change during the forecast period (2025–2034).

Diverticulitis Market Outlook

The diverticulitis therapeutics market is further expected to increase by the major drivers, such as the rising incident population, technological advancements, and upcoming therapies in the forecast period (2025–2034).

Management of diverticulitis primarily relies on supportive care and antibiotics for mild to moderate cases, with surgical interventions reserved for complicated cases involving abscess, perforation, or peritonitis. Off-label therapies, including certain anti-inflammatory agents and probiotics, are sometimes utilized to reduce inflammation, prevent recurrence, or manage symptoms, though evidence supporting their use remains limited.

Emerging therapies like MBK-01 aim to address underlying disease mechanisms, representing a first-in-class, and targeted approach in a space with no approved drugs. By potentially reducing recurrence and complications, this novel treatments could transform the management landscape and provide alternatives for patients inadequately served by current care.

With ongoing research and continued dedication, the future holds hope for even more effective treatments and, ultimately, a cure for this challenging condition. According to DelveInsight, the diverticulitis market in the 7MM is expected to change significantly during the study period 2020–2034.
