Autonomic Nervous System Disorders: Dizziness and Anxiety

Autonomic nervous system dysfunction causing dizziness and lightheadedness?

Hello, Dr.
Jiang.
I apologize for bothering you, but I would like to ask for your advice.
Three years ago, I suddenly experienced autonomic nervous system dysfunction.
Initially, I had occasional premature ventricular contractions (PVCs), which my cardiologist deemed harmless.
However, my anxiety and panic attacks worsened due to stress.
During that time, my heart rate would rise to 100-120 bpm just from walking.
Recently, my heart rate has often been between 60-80 bpm, and sometimes even drops to the 50s.
I consulted a neurologist who indicated that my parasympathetic nervous system is more active, suggesting that my body is in a fatigued state.
Despite sleeping over 9 hours a day, I am wondering what methods I can use to improve my condition.

Additionally, I have been experiencing some dizziness accompanied by neck pain, but doctors have said it is normal.
I am curious if you have heard of "sensory dizziness," as I feel more dizzy in large spaces like supermarkets, sometimes feeling as if the ground is swaying.
I experience a constant sensation of dizziness and pressure in my head.
I am unsure if this is caused by sensory dizziness or if it is related to my autonomic nervous system issues.

Lastly, I would like to know if autonomic nervous system dysfunction poses any dangers.
A previous doctor prescribed Yongkangxu, suggesting it might help, but I am hesitant to take it.
Does this medication provide benefits, or could it cause discomfort? Will my symptoms improve? What should I do? I feel so helpless.
Thank you for your assistance!

Dear Mr.
Hsieh,
You mentioned that "sleeping for 9 hours...
Yongkangxu said it would help." Yongkangxu contains two active ingredients: Flupentixol, which is an antipsychotic that has antidepressant and anxiolytic effects at low doses, and Meltracen, which is a mood stabilizer that exhibits activating effects at low doses.
When these two medications are combined, they provide properties such as antidepressant, anxiolytic, and mood-enhancing effects.
This medication is typically effective in alleviating symptoms during periods of significant emotional fluctuation.
Side effects may include insomnia.
For sleep issues, it is recommended to consider wearing a smartwatch with blood oxygen monitoring capabilities to track sleep and oxygen levels.
Additionally, avoid using electronic devices that emit blue light before bedtime, as they can inhibit melatonin production, making it difficult to fall asleep and leading to physical fatigue.
It is advisable to refrain from using your phone for at least one hour before sleep.
Thank you for your inquiry.
If you have any further questions, feel free to discuss them! Wishing you good health and peace.
Dr.
Jiang Junyi, Taoyuan Medical Center

Hello! Thank you for reaching out with your concerns regarding autonomic nervous system disorders, dizziness, and anxiety. Based on your description, it seems that you are experiencing a complex interplay of symptoms that can be quite distressing. Let’s break down your situation and explore potential solutions.

First, it’s important to understand that the autonomic nervous system (ANS) regulates involuntary bodily functions, including heart rate, blood pressure, and digestion. It consists of two main branches: the sympathetic nervous system (which prepares the body for 'fight or flight' responses) and the parasympathetic nervous system (which promotes 'rest and digest' activities). When there is an imbalance, such as an overactive parasympathetic response, it can lead to symptoms like bradycardia (slow heart rate), dizziness, and fatigue.

You mentioned experiencing episodes of heart palpitations, anxiety, and panic attacks, which can be exacerbated by stress and anxiety. It’s not uncommon for individuals with autonomic dysregulation to feel dizzy, especially in crowded or large spaces, as you described in the supermarket. This sensation, sometimes referred to as "perceptual dizziness," can be linked to anxiety and the body's heightened sensitivity to environmental stimuli.

Regarding your heart rate fluctuations, the fact that your heart rate has decreased to 60-80 beats per minute, and occasionally even lower, can be a sign of increased parasympathetic activity. While a resting heart rate in this range can be normal for some individuals, especially those who are physically fit, it’s essential to monitor how you feel during these episodes. If you experience symptoms like dizziness or faintness, it’s crucial to consult with your healthcare provider.

As for your concerns about the medication "Yongkangxu," which is likely a form of herbal or traditional medicine, it’s essential to discuss with your doctor whether it’s appropriate for your specific symptoms. Some herbal supplements can help with anxiety and autonomic regulation, but they may also have side effects or interact with other medications. If you are hesitant to start this medication, consider discussing alternative treatments or therapies with your healthcare provider.

To improve your symptoms, consider the following strategies:
1. Cognitive Behavioral Therapy (CBT): This form of therapy can help you manage anxiety and panic symptoms by changing negative thought patterns and behaviors.

2. Mindfulness and Relaxation Techniques: Practices such as meditation, deep breathing exercises, and yoga can help calm the nervous system and reduce anxiety.

3. Regular Physical Activity: Engaging in regular, moderate exercise can help regulate your autonomic nervous system and improve overall well-being.

4. Adequate Sleep Hygiene: While you mentioned getting over nine hours of sleep, ensure that your sleep environment is conducive to restful sleep and that you maintain a consistent sleep schedule.

5. Hydration and Nutrition: Staying well-hydrated and consuming a balanced diet can support overall health and may help alleviate some symptoms.

6. Gradual Exposure: If certain environments trigger your dizziness, consider gradually exposing yourself to these situations in a controlled manner to help desensitize your response.

7. Follow-Up with Specialists: If your symptoms persist or worsen, consider seeking a referral to a neurologist or a specialist in autonomic disorders for further evaluation and management.

In conclusion, while autonomic nervous system disorders can be challenging, many individuals find relief through a combination of lifestyle changes, therapy, and, when necessary, medication. It’s essential to work closely with your healthcare provider to develop a personalized treatment plan that addresses your specific symptoms and concerns. Remember, you are not alone in this journey, and there are effective strategies to help you regain control over your health. Take care!
