Patient discussion about dysautonomia.

Q. What is dysautonomia? My friend has dysautonomia. What does it mean? What are the symptoms? Is it curable?

A. Dysautonomia is a medical term often used to describe a group of complex conditions that are caused by a dysfunction of the autonomic nervous system (ANS). The ANS regulates all of the unconscious functions of the body, including the cardiovascular system, gastrointestinal system, metabolic system, and endocrine system. Symptoms of dysautonomia may include: Tachycardia (extremely fast heart rate), bradycardia (slow heart rate), palpitations, chest pain, dangerously low blood pressure, wide swings/sudden drops in blood pressure, orthostatic intolerance (the inability to remain upright), excessive fatigue, exercise intolerance, dizziness, fainting/near fainting, gastrointestinal problems, nausea, insomnia, shortness of breath, anxiety, tremulousness, frequent urination, convulsions, cognitive impairment, visual blurring or tunneling, and migraines. It is a chronic disease and is not curable.
