Lifting someone, especially a frail person, can result in injuries for all the people involved, and that is outside of the main story anyway. As a nurse, when medicated laxatives don’t work, we use pear juice, and that works wonders. There are ways to ‘help’ the removal of stool, apart from medications, without using things like a spoon, these include such things as surgery as well as pushing on the muscles around the anus gently. OP obviously has no training and is dangerous to the person they are taking care of, this should have been dealt with long before it came to this point. In hospital or care facility setting, 3 days for the average person before intervention, and if the interventions don’t work it is off for surgery and a colon cleanse. The risk of tearing and leaking dangerous bacteria into the abdominal or pelvic cavity are insanely high.
