Gallbladder: Chalky stool could be a liver/gallbladder issue, ibs or mucus or some other issue. I would really get to the doc sooner than later.

Mucus on stool: Mucus discharge occurs in up to 50% of patients with irritable bowel syndrome, with or without pain. Mucus may also be produced in response to partial obstruction, chronic constipation, rectal dysfunction, infection, ; even from secretory villous tumors of the rectum. At the very least stool studies ; probably a sigmoidoscopy should be considered, but a more extensive evaluation may be warranted.
