Correct Answer is B

Explanation

A) Incorrect. Visceral hypersensitivity is not related to an increased susceptibility to bacterial infections.

B) Correct. Visceral hypersensitivity in IBS means that the gut is more sensitive, leading to an increased perception of pain and discomfort from normal gut activities.

C) Incorrect. While inflammation may be present in some cases of IBS, it is not the primary definition of visceral hypersensitivity.

D) Incorrect. IBS has a physical basis, and visceral hypersensitivity is one aspect of its pathophysiology, not solely a psychological condition.

Correct Answer is B

Explanation

A) Incorrect. The brain-gut axis is indeed relevant to IBS and plays a significant role in its pathophysiology.

B) Correct. The brain-gut axis refers to the bidirectional communication between the central nervous system (brain) and the enteric nervous system (gut). In IBS, this interaction is complex and can influence gut motility, sensitivity, and overall symptom experience.

C) Incorrect. While the brain-gut axis is important, its primary impact in IBS is not related to nutrient absorption.

D) Incorrect. The brain-gut axis is relevant in various gastrointestinal disorders, including IBS, and is not limited to severe psychological disorders.
