Bowel: routine over chance.
Much is written about bladder management. Less about the bowel — even though it affects daily life just as much. This page covers the basics of neurogenic bowel dysfunction and what helps in practice.
What is a neurogenic bowel?
With a spinal cord injury, voluntary bowel control is impaired. The bowel itself still works — but communication between bowel and brain is disrupted. This affects both the sensation of needing to go and control of the sphincter.
Depending on injury level, there are two types:
Reflex bowel (upper motor neuron)
With a lesion above the conus medullaris, sphincter tone is preserved or increased. The bowel responds to stretch with reflex activity — useful for planned emptying (digital stimulation, suppositories, mini enemas). Most people with thoracic or cervical SCI have a reflex bowel.
Flaccid bowel (lower motor neuron)
With a lesion at conus medullaris or cauda equina level, sphincter tone is reduced. Reflex activity is absent — emptying relies more on abdominal pressure, manual evacuation and stool regulation. The risk of incontinence is often higher.
How often should the bowel be emptied?
Most people find a rhythm of one to three days. What matters is regularity: fixed times, a consistent sequence, no rush. A bowel plan is developed in rehab with the spinal cord centre and then adapted in daily life.
Rule of thumb: Judge a change in bowel management only after 3–5 bowel movements or one week. The gut responds slowly — hasty changes make things worse, not better.
What helps in daily life
Diet
Fibre (target: 25–30 g per day, increase gradually from 15 g), adequate fluids (1.5–2 litres, see fluid intake) and regular meal times. The gastrocolic reflex — eating or drinking stimulates bowel activity — can be used deliberately by planning bowel care shortly after a meal.
Movement
Any form of movement supports gut motility. Wheelchair sports, transfers, physiotherapy — anything beats sitting still.
Documentation
Record stool frequency, consistency (the Bristol Stool Scale helps), duration and anything unusual. Two weeks of documentation shows whether the routine is working — and gives the doctor a basis far better than "it's been more or less okay".
The Bladder & Bowel Manager app logs bowel movements with Bristol type, amount (from 🐜 to 🐘) and time. Statistics show average intervals and consistency distribution. A PDF report summarises everything for the next appointment.
When there is no time to wait
See a doctor promptly: Faecal incontinence that suddenly worsens. No bowel movement for more than three days despite all measures. Abdominal pain or bloating with nausea. Blood in stool. With SCI at T6 or above: pounding headache and sweating — signs of autonomic dysreflexia, which can also be triggered by a full bowel.
