Which item is NOT listed as a cause of IBS in the material?

• A. Gluten sensitivity
• B. Suppression of natural urges
• C. Coffee
• D. Raw fruit/veg

Answer: (A)

The main idea here is how IBS symptoms are triggered by things that affect gut movement and sensation. In the material, suppression of natural urges, coffee, and raw fruit/vegetables are cited as factors that can provoke or worsen IBS symptoms. Suppressing the urge to defecate can disrupt normal bowel reflexes, leading to stool withholding, increased stool load, and heightened abdominal discomfort. Coffee stimulates gut motility and can increase urgency, rushing the bowel and triggering symptoms in sensitive individuals. Raw fruit and vegetables bring high fiber and fermentable components that can boost gas production and distension, often aggravating IBS symptoms like bloating and pain.

Gluten sensitivity isn’t listed as a cause in that material, even though some people report gluten-related symptoms. The distinction is that IBS triggers in that context come from behavioral and dietary irritants affecting motility and sensitivity, rather than a gluten-driven autoimmune process.
