Telling somebody that you are suffering from borborygmus might make it sound like you are coping with something really horrible and that they might want to start putting together your final plans. In reality, virtually everybody deals with borborygmus on a daily basis. What is this mysterious affliction? Your tummy rumbling. The sound of gurgling or growling that comes from your stomach occasionally can be caused by food digesting or the gas in an empty belly being forced through your intestines.
