Will taking antibiotics cause diarrhea or loose stools?

Patient's Query

Hello doctor,

I took antibiotics about a month ago, and ever since the fourth day of antibiotic treatment, I have been suffering from diarrhea or loose stools. On the fourth day, I had bad cramps and loose stools that lasted from the fourth day to the seventh day. This then returned afterward with even worse pains, but this time, I had yellow stool followed by diarrhea. Ever since I have been having loose stools on and off that is foul smelling and mushy. Is this because of the antibiotics, or is it an infection?

Hello,

Welcome to icliniq.com.

Your diarrhea could be a direct side effect of the antibiotic, in which case, it should resolve after stopping the antibiotic. It could also be due to a condition called Clostridium difficile infection (C. diff for short). C. diff is a bacterium typically found in the intestines of most people. But under certain circumstances (frequent exposure to antibiotics), a couple of strains of this bacteria can multiply and produce toxins (called C diff toxin A and B). This can provide diarrhea-sometimes bloody, with crampy abdominal pain.

I suggest getting tested for C diff. You need to submit a stool sample for C diff toxin. If it is positive, there are treatments for it includes oral Vancomycin, Fidaxomicin, or Metronidazole. I hope this helps.
