Sedated terminal cancer patient, no viable conversation or food in about 4 days. Only minimal water intake for oral meds. Refused most while able to voice such. Sleeps now constantly but has had 2 very overpowering foul bowel movements. Watery to paste consistency, dark brown and now almost gelatinous. The patient is aware of nothing it seems at this point. If no food in 3 to 4 days.....what is causing the foul bowel movements?
