Dysautonomia
Dysautonomia is the dysfunction of the autonomic nervous system, presenting unique challenges in a person’s health by impacting multiple bodily functions. The nervous system is divided into the central nervous system, which includes all the nerves in the brain and spinal cord, and the peripheral nervous system, which includes all the nerves in the body other than the brain and spinal cord. The peripheral nervous system is further split into two – the somatic and the autonomic divisions. The somatic division is involved in voluntary control of things like skeletal muscle movement as well as conscious sensory processing. The autonomic division is in charge of all involuntary functions, such as regulation of breathing, heart rate, blood pressure, temperature, and digestion. It also has influence over certain glandular secretions, bladder contractility and relaxation, and indirectly, sleep.
Dysautonomia can not only present in a variety of ways across the board, but two people with the same form of dysautonomia may have different symptoms. Some of the more common examples of dysautonomia are orthostatic hypotension, POTS (postural orthostatic tachycardia syndrome), vasovagal syncope, and IST (inappropriate sinus tachycardia).
