A Dysautonomia symptom checklist is important because it helps to identify the symptoms of dysautonomia, which is a disorder of the autonomic nervous system. The autonomic nervous system controls involuntary functions of the body, such as heart rate, blood pressure, and digestion. Dysautonomia can cause a wide range of symptoms, including lightheadedness, fainting, and fatigue. Having a checklist of symptoms can help to identify the disorder and get the appropriate treatment.
