Risk factors

Factors that might increase your risk of autonomic neuropathy include:

• Diabetes. Diabetes, especially when poorly controlled, increases your risk of autonomic neuropathy and other nerve damage. You're at greatest risk if you have difficulty controlling your blood sugar.
• Other diseases. Amyloidosis, porphyria, hypothyroidism and cancer (usually due to side effects from treatment) also can increase the risk of autonomic neuropathy.
