Theautonomic nervous system is responsible for controlling various important processes in the human body: it influences heart function, blood pressure and respiration rate, thermoregulation, pupil width and the secretion of various glands. When the autonomic system becomes dysfunctional, people may experience a variety of symptoms, usually significantly impeding function.

Dysautonomia can be primary or secondary. Primary dysautonomia is said to be caused by diseases of the nervous system (e.g. neurodegenerative diseases), while secondary dysautonomia may occur in the course of coeliac disease, systemic lupus erythematosus, diabetes or rheumatoid arthritis.

Thesymptoms of dysautonomia, like its causes, can be truly diverse and include the following:

• thermoregulatory disorders,
• visual disturbances,
• fainting,
• heart rhythm disturbances,
• dizziness,
• respiratory disorders,
• mood swings,
• weakness,
• impaired concentration,
• feelings of restlessness.

Before treating dysautonomia , it is necessary to find the cause of the dysautonomia - as the necessary treatment interventions may vary depending on what led to the problem. Primary dysautonomias are generally incurable, but when the problem arises in connection with the presence of some other condition (e.g. diabetes mellitus), its proper treatment may lead to a reduction in the severity of dysautonomia symptoms or even to their complete disappearance.
