I had throat surgery on March 25th and I’m still recovering. I finally started eating somewhat substantial food on Saturday (like soup, mashed potatoes, etc) and similar stuff since then. But since then, I’ve also had wicked GI distress (including a big bout of diarrhea each morning and each night). why is this happening now after I’ve started eating non-liquid food again? I was on Ensure and slurpees for the week before, if it matters.

I’ve been sick after having surgery. Why?
