Finished antibiotics. now very soft stool , heavy, lying in ground of loo. started w/ antib. still happening, 1+ week. what to do to make normal?

Probiotics: This is probably caused by the antibiotic. Many antibiotics can kill off helpful intestinal bacteria that keep us regular. This can lead to abnormal stools, and/or diarrhea. This is most often helped with a probiotic tablet, or an active culture yogurt. If the problem persists, fever occurs you should see your doctor to be screened for Clostridium difficile.
