A 57-year-old man presents to his GP

A 57-year-old man presents to his GP. For the past few weeks, he has been suffering from loose stools in the mornings. He feels otherwise well, and has no abdominal pain, and is wondering whether it may be due to one of the new medications he has been recently started on –  which includes aspirin, atorvastatin, bisoprolol and lansoprazole.

For the case above, please select the SINGLE most likely cause of the adverse reaction being described. Select ONE option from the list above.
