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.

A. "IBS is primarily caused by structural abnormalities in the intestines." B. "The exact cause of IBS is unknown, but it's believed to involve a combination of factors, including abnormal gut motility and sensitivity." C. "IBS is exclusively caused by psychological stress and anxiety." D. "IBS is primarily caused by bacterial infections in the intestines."

Correct Answer is B

Explanation

A) Incorrect. While structural abnormalities can contribute to gastrointestinal disorders, IBS is not primarily caused by such abnormalities.

B) Correct. The exact cause of IBS is unknown, but it is believed to be a multifactorial condition involving abnormal gut motility, heightened visceral sensitivity, and other factors. Psychological and genetic factors may also play a role.

C) Incorrect. While psychological factors can exacerbate symptoms in some individuals with IBS, they are not the sole cause of the condition.

D) Incorrect. While bacterial infections can lead to similar symptoms, IBS is not primarily caused by infections.
