Before we begin: Dysautonomia is a disorder of the autonomic nervous system, which controls.

This tutorial walks you through everything you need to know about autonomic nervous system disorders. We explain it in plain language, step by step, so whether you are a student, a patient, or simply curious, you will come away with a solid understanding.

We cover what it is, why it matters, how it is diagnosed, and what you can do about it. Key facts are called out along the way.

Your autonomic nervous system is the part of your nervous system that controls involuntary actions, such as the beating of your heart and the widening or narrowing of your blood vessels. When something goes wrong in this system, it can cause serious problems, including:

Blood pressure problems

Heart problems

Trouble with breathing and swallowing

Erectile dysfunction in men

Autonomic nervous system disorders can occur alone or as the result of another disease, such as Parkinson’s disease, alcoholism and diabetes. Problems can affect either part of the system, as in complex regional pain syndromes, or all of the system. Some types are temporary, but many worsen over time. When they affect your breathing or heart function, these disorders can be life-threatening.

Some autonomic nervous system disorders get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms.
