Autonomic Dysreflexia

Autonomic dysreflexia is a condition that can affect people with spinal cord injuries at or above the T6 level. It’s a serious medical emergency that can lead to life-threatening complications if not treated promptly. In this article, we’ll break down everything you need to know about autonomic dysreflexia, using simple language to ensure accessibility and understanding.

Types of Autonomic Dysreflexia:

1. Complete Autonomic Dysreflexia: This type occurs when the body’s autonomic nervous system overreacts to a stimulus, causing a sudden spike in blood pressure. It’s a severe form of the condition.
2. Partial Autonomic Dysreflexia: In this type, the response of the autonomic nervous system is not as extreme as in complete autonomic dysreflexia. The symptoms may be milder but still require attention.

Causes of Autonomic Dysreflexia:

1. Bladder Problems: A full bladder is a common trigger. It can be caused by urinary tract infections, catheter blockages, or simply the need to urinate.
2. Bowel Issues: Constipation or impaction can lead to autonomic dysreflexia.
3. Pressure Sores: Any pressure sore or skin irritation can set off the autonomic nervous system.
4. Tight Clothing: Wearing tight clothes can cause discomfort and trigger autonomic dysreflexia.
5. Skin Irritations: Anything that irritates the skin, like burns or insect bites, can be a cause.
6. Extreme Temperatures: Both hot and cold temperatures can trigger this condition.
7. Sexual Activity: Engaging in sexual activity can cause autonomic dysreflexia in some cases.
8. Ingrown Toenails: Even minor foot problems can lead to autonomic dysreflexia.
9. Bone Fractures: A broken bone can stimulate the autonomic nervous system.
10. Surgery: Certain surgical procedures can trigger autonomic dysreflexia as a response to the body’s stress.
11. Pregnancy: Pregnancy can cause changes in blood pressure and trigger autonomic dysreflexia in some women with spinal cord injuries.
12. Menstruation: Some women may experience autonomic dysreflexia during their menstrual cycle.
13. Infections: Any infection in the body, such as pneumonia or urinary tract infections, can be a cause.
14. Medications: Some medications can affect blood pressure and trigger autonomic dysreflexia as a side effect.
15. Bladder Stones: These can cause discomfort and stimulate the autonomic nervous system.
16. Kinked Catheter Tubing: A kink or blockage in a catheter can lead to autonomic dysreflexia.
17. Kidney or Bladder Stones: The presence of stones in the urinary system can be a trigger.
18. Pressure on the Body: Pressure on any part of the body can lead to skin irritation and trigger autonomic dysreflexia.
19. Friction: Excessive friction from activities like wheelchair use can cause skin irritation.
20. Stress: High levels of stress or anxiety can also trigger autonomic dysreflexia.

Symptoms of Autonomic Dysreflexia:

1. Sudden High Blood Pressure: Blood pressure can rise dramatically, leading to a severe headache.
2. Severe Headache: The intense headache is a hallmark symptom.
