Dysautonomia, high blood pressure

During the 19th century doctors discovered a specific medical condition and called it neurasthenia. Patients suffering from neurasthenia used to complain about fatigue, weakness, odd pains, dizziness and they were prone to passing out. Since there was nothing to be done for such patients doctors simply classified the condition as a 'weak nervous system' and patients were bed ridden until they recover or eventually die.

What about Today?

Today we still have people complaining about the same symptoms. However, their illness is not called neurasthenia any more but can be classified as chronic fatigue syndrome, vasovagal or neurocardiogenic syncope, anxiety, panic attacks, postural orthostatic tachycardia syndrome or fibromyalgia. All the mentioned conditions are actually closely related to volatility of the autonomic nervous system.

Dysautonomia and the Autonomic Nervous System

The autonomic nervous system is a part of the nervous system in charge with all the 'unconscious' body functions such as heart rate and breathing. The autonomic nervous system consists of the sympathetic and the parasympathetic system. While the first one acts as a powerful contributor of the 'fight or flight' reactions of the body such as rapid heart rates, increased breathing and intensive blood flow to muscles, the parasympathetic nervous system is connected with 'quiet' functions in the body (e.g. functions of the digestive system).

It is expected from these two systems to remain in a perfect balance. However, in people suffering from dysautonomia, one of these systems becomes predominant and this significantly interferes in proper functioning of certain body organs and organ systems.

There is a whole variety of symptoms and signs of this disorder and disturbing aches and pains, fatigue, inertia, anxiety attacks, tachycardia, hypotension, low exercise tolerance, irritable bowel syndrome, sweating, dizziness and blurred vision are only some of them.

The symptoms cannot be predicted and can vary from one attack to another.

Causes of Dysautonomia

There are many underlying causes of dysautonomia. The condition seems to be closely related to heritage. Namely, many of patients inherit the propensity to develop the condition. Furthermore, dysautonomia may be triggered by different viral illnesses or develop after exposure to certain chemicals. In some cases dysautonomia may occur due to trauma.

Prognosis

Today prognosis of dysautonomia is much better comparing to the 19th century. The explanation is simple. Today people are not simply bedridden and left to recover on their own. In some cases the symptoms may go away spontaneously while other patients simply get used to them and try to live their lives as normal as possible.
