The time of bowel cleansing before death is relatively fast, but it is not fixed, and the time of bowel cleansing is not the same for each person, so it cannot be generalized.
Before dying, people cleanse their bowels because the body is functioning in a state of complete lack of self-control, which is known as exhaustion. This is also a common sign that older people are dying.
Bowel cleansing before dying in the elderly is usually associated with a loss of rectal sphincter function, which usually results in a gradual abnormality or loss of control of normal bowel function, and the patient may exhibit fecal incontinence, with unconscious bowel movements.
There is also a gradual loss of systemic function before death, accompanied by abnormal neurological function, which may be characterized by sudden mental vigor and sudden anger, followed by gradual delirium.
