Yes: in some people, especially those not used to drinking coffee.

No: It can not be caused by coffee beans but most probably caused by cream or milk in the coffee if you have lactose intolerance In some people drinking morning coffee makes them go to bathroom to move bowel,but it is not diarrhea and not much bloating,it is just a reflex activity which some like as it keeps them regular
