Dysautonomia - Definition

February 2017


Definition


Dysautonomia, also called autonomic dysfunction, is a dysfunction of the autonomic nervous system, which regulates involuntary organ function control, such as those of digestion. Nerves associated with the autonomic nervous system include two types, called sympathetic and parasympathetic, and have opposite functions. Dysautonomia can independently affect either of these systems, in one or more organs, resulting in clinical symptoms that are very different from one individual to another. Dysautonomia can cause an acceleration or deceleration in the activity of target organs: this can lead, for example, to diarrhea or constipation when the digestive tract is affected.
