A spinal cord injury can affect the autonomic nervous system (ANS), which is the part of the body that controls involuntary functions like blood pressure, body temperature, heart rate, and digestion. Because communication between the brain and parts of the body can be disrupted below the injury, it can create health challenges and complications.
Some common autonomic nervous system (ANS) complications include cardiovascular instability, such as significant drops in blood pressure or an abnormally slow heart rate. Another serious complication is autonomic dysreflexia, a sudden and potentially dangerous spike in blood pressure. Temperature dysregulation also may occur due to impaired sweating and reduced ability to regulate body temperature. Bowel or bladder dysfunction also can result from disrupted autonomic control.
Rehabilitation helps individuals learn how to recognize changes in their bodies, prevent complications, and safely manage daily activities. Education, therapy, and support are key components of maximizing independence and quality of life.
