Welcome to HealingWell!
When your doc started you on antibiotics did s/he mention you might want to take probiotics as well? The antibiotics kill off both the good and the bad bacteria in your intestines. This, in turn, can cause bowel changes - in particular, diarrhea. Anyone on antibiotics should be taking some type of probiotic in conjunction. Eating yogurt or taking probiotics pills or powder can help your gut tremendously. Have you heard of the yogurt Dannon Activia?
