What is the reason for not taking a shit?

1. Dietary factors such as

lack of dietary fiber in diet, eating less, insufficient drinking water, etc., can easily lead to insufficient stool generation, which can lead to difficult defecation.

2. Mental psychological factors such as

anxiety, depression or mental stress, etc., may lead to autonomic nervous dysfunction, which may affect normal intestinal movement rhythm and difficult defecation.

3. Nervous system diseases

. Diabetic peripheral neuropathy, multiple sclerosis, spinal cord injury and other diseases may affect the function of the nervous system responsible for controlling intestinal motility, and thus affect defecation.
