Spinal cord injury defecation mostly refers to the defecation function, spinal cord injury defecation function is possible to recover, mainly related to the location of the injury and the degree of injury and other factors. For spinal cord concussion, which is a mild spinal cord injury, only the function is damaged, and the bowel function can be recovered gradually. For cervical cord injury, thoracic cord injury and lumbar cord injury resulting in sensory impairment and paralysis below the damaged plane, bowel function is more difficult to recover. For the cauda equina nerve injury caused by spinal cord injury, most of the defecation function can be restored after active and effective treatment after the nerve compression is lifted. Patients with defecation disorders caused by spinal cord injury should consult a doctor in time and follow the doctor’s instructions to avoid delaying the condition.
