Does anyone have chronic diarrhea?

My husband was diagnosed with acinar cell pancreatic cancer of the head Oct 11 2024 he started with diarrhea prior to diagnosis May 2024 with c diff since then to loose stools have not gone away Tried creon Zenpep now protonix with viokase
Makes no difference they tested him for sibo and he was positive waiting for insurance to approve expensive antibiotic Takes Imodium lomotil and tincture of opium day 4-8 has 11-12 liquid stools talked to gastro today and he said 100 percent his pancreatic cancer but why isn’t enzymes working tried increasing dose does nothing Just wondering if others have this problem thanks
