Editing Autonomic neuropathy (section)

== Causes ==
Many health conditions can cause autonomic neuropathy. Some common causes of autonomic neuropathy include:
* [[Diabetes]], which is the most common cause of autonomic neuropathy, can gradually cause nerve damage throughout the body.
* [[Vitamin B12 deficiency|Vitamin B<sub>12</sub> deficiency]] ([[pernicious anemia]])
* Injury to nerves caused by surgery or radiation to the neck.
* Treatment with certain medications, including some drugs used in cancer [[chemotherapy]].
* Abnormal protein buildup in organs ([[amyloidosis]]), which affects the organs and the nervous system.
*  An abnormal attack by the immune system ([[autoimmune autonomic ganglionopathy]]), sometimes as part of a [[paraneoplastic syndrome]] which can occur even when cancer has not yet been diagnosed.
* Certain infectious diseases. Some viruses and bacteria, such as [[botulism]], [[Lyme disease]] and [[HIV]], can cause autonomic neuropathy.
* Inherited disorders. Certain [[hereditary disorder]]s can cause autonomic neuropathy.
* [[Autoimmune disease]]s, in which the immune system attacks and damages parts of the body, including the nerves. Examples include [[Sjögren syndrome]], [[systemic lupus erythematosus]], [[rheumatoid arthritis]] and [[celiac disease]]. [[Guillain–Barré syndrome]] is an autoimmune disease that happens rapidly and can affect autonomic nerves.
