Acidic poop

I am waiting (on funding) to start a new biologic - I think it's going to be Stelara.

I asked my GI if I could just consume clear fluids as needed to calm down my bleeding. He thought it would be ok- I'm an overweight person so dropping a few pounds would actually be good).

By the end of day one, of consuming mostly chicken or turkey broth (made myself with bones, meat, veggies and plenty of salt) I stopped bleeding!

On day 4, the 'stool' I was passing turned greenish and felt like fire and glass as I passed it.

I've had that same problem when I do a bowel prep (my clear fluids for bowel prep don't include homemade broth). I assumed it was the caustic stuff in the prep but this 'acid' came from me!

The pain has eased up when I started eating food and I think I'd rather bleed than have that pain again.

I frequently have fatty stools but my GI never comments/kinda just ignores it when I tell him that.

Sure scared me! Does anyone know what I did to myself, what happened?

Thanks...I've had this for 8 years now and there's so much I don't know.

I wish you the best too!
