What is Dysautonomia or Autonomic Dysfunction?
Dysautonomia or Autonomic Dysfunction is an umbrella term used to describe several different medical conditions that cause a malfunction of the Autonomic Nervous System. The Autonomic Nervous System controls the "automatic" functions of the body that
we do not consciously think about, such as heart rate, blood pressure, digestion, dilation and constriction of the pupils of the eye, kidney function, and temperature control.
People living with various forms of dysautonomia have trouble regulating these systems, which can result in lightheadedness, fainting, unstable blood pressure, abnormal heart rates, malnutrition, and in severe cases, death. Dysautonomia is not rare. Over 70 million people worldwide live with various forms of dysautonomia. People of any age, gender or race can be impacted.
2 Parts of the Autonomic Nervous System
The autonomic nervous system, also known as the involuntary nervous system, regulates those facets in the body that occur automatically, such as breathing, blood pressure, digestion, heart beat, bladder function and narrowing or widening of the blood vessels. It is composed of two branches - the parasympathetic nervous system and the sympathetic nervous system.
Sympathetic
The sympathetic nervous system is also known as our stress response system, or the fight or flight system, and it is set into motion when we experience stress. It increases our heart rate and blood pressure, dilates pupils, restricts circulation, slows down digestion, relaxes the bladder, makes us more alert and aware and provides a boost in energy so that we are capable of dealing with the stressful situation effectively. It increases energy and is often referred to as the accelerator of the autonomic nervous system.
Parasympathetic
The job of the parasympathetic nervous system is the exact opposite. Once the stressful event is over, it brings the heart rate and blood pressure back to normal, constricts pupils, improves circulation, enhances digestion, calms us down, contracts the bladder and puts us into a state of rest and relaxation. It conserves energy and is often referred to as the breaks of the autonomic nervous system.
What Causes Dysautonomia or Autonomic Nervous System Dysfunction?
When the autonomic nervous system is functioning as it should, the sympathetic nervous system and the parasympathetic nervous system work in perfect harmony together to maintain balance in the body. The sympathetic nervous system provides us with the tools we need to respond to stress adequately and the parasympathetic nervous system restores us to our normal state of peace and tranquility.
Dysautonomia, or autonomic nervous system dysfunction, occurs when these two systems fail to work together in harmony. The most common scenario is the sympathetic nervous system remains dominant most of the time and the parasympathetic rarely turns on, which is referred to as sympathetic dominance.
When this occurs, then
the body remains in a state of fight or flight most of the time or at all times. The stress response system never or rarely turns off. If the body remains in a state of fight or flight all the time, then many degenerative processes begin to happen and result in a variety of chronic health conditions and overall poor health like those in our list above, because it is only supposed to be used for brief emergencies.
Our assessment services for the Dysautonomia or Autonomic Dysfunction:
EEG biofeedback and autonomic dysfunction (dysautonomia) assessment
The fight-or-flight response activates the sympathetic portion of the autonomic nervous system resulting in numerous physiological and mental alterations. Activation of the sympathetic nervous system was able to be quantitatively measured using EEG biofeeedback.
ES-Teck assessment
The ES-Teck assessment is not a diagnostic tool. This device gives health care providers and their clients invaluable information by allowing them to measure and monitor various characteristics of the body’s physiology. Using a finger “Oximeter” it allows for observation of heart rate, tissue oxygen uptake, arterial stiffness, hemodynamic indicators and autonomic nervous system (ANS) levels of activity. Gives health care providers and patients invaluable information by allowing them to measure and monitor various characteristics of the body’s physiology and autonomic nervous system conduction.
可否听说过自律神经失调？通常有自律神经失调症状的人，在經過各種儀器檢查出來都很正常并查不出病因的。
面对自律神经失调的人，严重者甚至会有“逛医院或诊所（即不停的找寻病源但无法找着）”的问题。
自律神經失調
並不是一種病，而是一系列的症狀，也就是症候群，病因可能有許多種，也有許多種疾病會出現這些症狀，例如抑郁症depression、恐慌症panic attack or anxiety disorder等等。因為針對的器官不同，可能出現以下某些症狀：
1)倦怠、
2)口乾、
3)心悸、
4)頭暈頭痛、
5)焦慮恐慌、
6)心律不整等、
7)姿態性低血壓、
8)呼吸急促、
9)胃痛、
10)头疼、
11)腹脹、腹鳴、腹瀉、泻肚子或便秘等不止。
基本上，幾乎全身都有自律神經分布，所以症狀也相當多樣。
這裡將自律神經失調分成2種，快快了解成因，改善自律神經失調，告別沒有朝氣的自己！
交感神經讓你活動：
當身體需要活動、抗壓時，就是交感神經活躍的時候。這時心臟、肺的作用力大幅提升，體溫與血壓也跟著上升，調整身體狀態，使你精神飽滿，又能燃燒體脂肪！此時消化與排泄作用則會進入休息狀態。
交感神經活躍時的狀態：
★大腦活動旺盛 - 快速處理接收的情報，掌管心臟與肺臟。
★不易有睡意 - 腎上腺素分泌抗壓荷爾蒙，提高大腦與身體的活動量，不易有睡意。
★心跳加快，血壓上升 - 加速心臟跳動，將身體活動所需的充足血液，送到身體各器官。
★消耗熱量 - 交感神經運作，消耗熱量，燃燒體脂肪！
★支氣管擴張 - 支氣管擴張，呼吸次數增加，將大量空氣送入肺中，提供新鮮酵素。
★子宮收縮 - 交感神經活躍時，子宮會收縮，例如生產時收縮子宮，將小Baby順利產出。
★抑制胃酸分泌 - 心與肺活動時，腸胃不須有太大活動，所以會抑制胃酸分泌，以利能量釋放。
★腸胃蠕動變慢 - 使排便暫緩、腸胃蠕動變慢，持續強烈緊張而便秘時，就是交感神經過度興奮。
★不易排尿 - 身體活動時，必須讓環境穩定，抑制排尿則可以變得更有效率。
副交感神經讓你放鬆：
副交感神經會舒緩緊張，放鬆身體，受到交感神經的刺激，減緩心臟與肺的活動力，使胃腸活動旺盛，促進消化吸收，將不需要的物質以尿液或汗排出。
尤其在睡眠時，活動力更是旺盛！
副交感神經活躍時的狀態：
★大腦呈休息狀態 - 大腦進入休息狀態，使全身放鬆。
★心臟跳動減緩，血壓下降 - 休息時不需要太多血液，所以心跳減緩，血壓下降。
★支氣管收縮 - 在休息狀態中，身體不需做劇烈活動，所以也不須要太多空氣。
★腸胃蠕動旺盛 - 腸胃蠕動旺盛，就能將老廢物質排出體外，在放鬆狀態容易想要排便，就是這個緣故呢！
★刺激生長激素 - 副交感神經活躍，刺激肌膚等的新陳代謝，使生長激素分泌旺盛。
★舒緩子宮緊張 - 使肌肉休息，舒緩子宮緊張，例如抑制子宮收縮，讓小Baby可以在子宮中長大。
★分泌胃酸 - 副交感神經活躍，是為了儲存能量，於是胃的活動大增，胃酸分泌增多。
★容易排尿 - 副交感神經活躍，膀胱收縮，刺激排尿作用，將老廢物質排出體外。
交感神經與副交感神經，為使每天的必要性活動能執行，不斷地做轉換，使身體保持最佳狀態！
不過，壓力過大，交感神經會持續過度興奮狀態；過度疲勞，副交感神經同樣也會有過度興奮情形產生，当2種神經無法順利轉換，平衡失調。失調的情況持續下去，副交感與交感神經都會因為活動過盛，而感到疲倦，到最後一點幹勁也沒有，身心俱疲，便會產生抑郁depressed狀態。
