iverticulosis is one of the most common findings seen during colonoscopy, especially in adults over 50. It refers to small pouch-like outpocketings that form along the wall of the colon. Most people with diverticulosis feel perfectly well and may never experience symptoms throughout their lifetime.
The problem begins when these pouches become inflamed or infected—a condition known as diverticulitis. This can cause abdominal pain (often on the lower left or right side), fever, nausea, or changes in bowel habits. In some cases, diverticula can also bleed, leading to painless but sometimes significant rectal bleeding.
What causes diverticulosis? Aging plays a major role, but lifestyle factors matter. Low dietary fiber intake, physical inactivity, excess weight, smoking, and frequent use of certain pain relievers (such as non-steroidal anti-inflammatory drugs) increase the risk of complications. In Asian populations, including Filipinos, diverticula are more commonly found on the right side of the colon, which can sometimes confuse diagnosis.
The reassuring news is this: most people with diverticulosis will never develop diverticulitis. For those who do, modern medical care has evolved. Mild, uncomplicated diverticulitis can often be managed conservatively, sometimes without antibiotics, under close medical supervision. Severe cases, however, require prompt medical attention and may need hospitalization.
Prevention remains the cornerstone of care. A fiber-rich diet, adequate hydration, regular physical activity, smoking cessation, and weight control significantly reduce the risk of complications. Old advice to avoid nuts, seeds, and popcorn has been disproven and is no longer recommended.
The key message is balance—not fear. Diverticular disease is common, manageable, and largely preventable. With informed lifestyle choices and early medical evaluation of warning signs, most people can live full, active lives without major disruption from this condition.
In this issue, we are also pleased to welcome Dr. Anthony “Tony” Leachon as a regular columnist of H&L. A highly respected internist-cardiologist, former president of the Philippine College of Physicians, and a steadfast advocate for health reform, Dr. Leachon brings a courageous and principled voice to today’s most pressing health issues. His insights do more than inform—they challenge, inspire, and call readers to action, as he fearlessly confronts corruption and unacceptable practices that undermine the fundamental right of every Filipino to accessible and adequate healthcare.
