Autonomic nervous system dysfunction


Last month, I experienced severe dizziness, heart arrhythmia with a heart rate of 140 beats per minute, shortness of breath, chest tightness, nausea, numbness in both hands, and elevated blood pressure.
I felt extremely unwell, restless, and was hospitalized for 8 days.
The doctor initially suspected a myocardial infarction, but blood tests and cardiac and abdominal ultrasounds did not reveal any signs of myocardial infarction or other issues.
However, after the incident, I developed symptoms such as abdominal bloating, excessive gas, shoulder pain, and extreme fear (fear of recurrence), along with a general feeling of being unwell.
After being discharged, I consulted a traditional Chinese medicine practitioner who diagnosed me with autonomic nervous system dysfunction.
Now, I occasionally experience episodes with brief shortness of breath, chest tightness, fear, abdominal bloating, and excessive gas, but the symptoms are milder.
However, I am still worried whether there is an issue with my internal organs or heart.
Doctor, could you please confirm if I have autonomic nervous system dysfunction? If not, which specialty should I consult? Thank you.

Many diseases can potentially present with what is known as autonomic nervous system dysregulation.
Based on the symptoms you have described, it does appear that you are in a state of anxiety.
Therefore, if your physical examination does not reveal any corresponding pathological signs, you may want to seek assistance from a psychiatrist to address your anxiety issues.
Wishing you well.

Based on your description, it sounds like you are experiencing a range of distressing symptoms that could indeed be associated with autonomic nervous system (ANS) disorders. The autonomic nervous system regulates involuntary bodily functions, including heart rate, blood pressure, digestion, and respiratory rate. When this system is out of balance, it can lead to a variety of symptoms, many of which you have mentioned.

Your symptoms, such as severe dizziness, palpitations (heart rate of 140 beats per minute), shortness of breath, chest tightness, nausea, and numbness in your hands, are concerning and can be indicative of an ANS disorder. The fact that you were hospitalized and initially suspected of having a myocardial infarction (heart attack) underscores the seriousness of your symptoms. However, since tests ruled out significant cardiac issues, it is plausible that your symptoms may be related to anxiety and autonomic dysregulation rather than a primary cardiac or gastrointestinal problem.

The symptoms you describe, including abdominal bloating, excessive gas, shoulder pain, and feelings of extreme fear or anxiety, can be manifestations of a condition known as panic disorder or generalized anxiety disorder, which can also lead to autonomic dysregulation. The fear of having another episode can perpetuate a cycle of anxiety, leading to further physical symptoms.

In terms of management, it is essential to address both the physical and psychological aspects of your condition. Here are some recommendations:
1. Consult a Specialist: Since your symptoms are multifaceted, it would be beneficial to consult with a neurologist or a specialist in autonomic disorders. They can conduct further evaluations to rule out any underlying neurological conditions.

2. Psychological Support: Given the anxiety component, working with a mental health professional, such as a psychologist or psychiatrist, can be very helpful. Cognitive-behavioral therapy (CBT) is particularly effective for anxiety disorders and can help you develop coping strategies to manage your fears and symptoms.

3. Lifestyle Modifications: Incorporating stress-reduction techniques such as mindfulness, meditation, yoga, or tai chi can be beneficial. Regular physical activity can also help regulate the autonomic nervous system and improve overall well-being.

4. Dietary Considerations: Since you mentioned gastrointestinal symptoms, consider keeping a food diary to identify any potential food triggers. Eating smaller, more frequent meals and avoiding caffeine and alcohol may also help alleviate some symptoms.

5. Medication: If anxiety is a significant component of your symptoms, medications such as SSRIs (selective serotonin reuptake inhibitors) or benzodiazepines may be prescribed by a psychiatrist to help manage anxiety levels.

6. Follow-Up Care: Regular follow-ups with your healthcare providers are crucial to monitor your symptoms and adjust treatment as necessary. If you experience any new or worsening symptoms, seek medical attention promptly.

In conclusion, while it is possible that you are experiencing autonomic nervous system dysregulation, it is essential to approach your symptoms holistically. By addressing both the physical and psychological aspects of your health, you can work towards finding relief and improving your quality of life. Always consult with healthcare professionals who can provide personalized advice and treatment options based on your specific situation.
