I am having recurring bouts of diarrhea with smelly stool every 10-15 days since 4 January . It gets okay by itself in 1-2 days and then reccurs .I've lost 8 kgs weight in two months. There are no other symptoms but I feel low on energy after diarrhea..gone through all allergy tests and those were negative..I've taken 14 day course of rifaximin and 8 day course of ofloxacin and ornidazole twice but in vain...stress doesn't seem to be the problem as the diarrhea occurs unexpectedly
