Could candida overgrowth be a culprit in the loss of peristalsis after intestinal infection treated by antibiotics? Yes, one hundred percent. Fungal elements overgrowth after antibiotics are most common. You can pick up some parasites and other oddball things because the antibiotic probably wouldn't have killed them.
A nice thing about candida overgrowth is that you could do anti-candidal therapies. You work with somebody who does this and gives anticandidal therapies over the course of a month and see if the peristalsis doesn't return.
If you do testing for small intestinal bacterial overgrowth that's negative, the next place we usually look is the fungal elements, yeast, etc and so that makes total sense. Yes.
