Which item is not listed as an IBS trigger?

• A. Caffeine intake
• B. Lack of fiber
• C. Food allergies
• D. Stress

Answer: (A)

Triggers for IBS symptoms can vary, but they are often tied to how the gut responds to stress and what we eat. Stress is a well-known factor that can flare IBS symptoms through the gut–brain connection, making abdominal pain, bloating, and changes in bowel habits worse. A lack of dietary fiber can alter stool form and movement, potentially worsening IBS symptoms for some individuals. Food-related reactions, such as intolerances or sensitivities, can also provoke symptoms in those who are susceptible. Caffeine intake, while it can irritate the gut for some people, isn’t typically listed as a standard IBS trigger in foundational nutrition materials, so it’s the item not listed as a trigger in these contexts.
