Autonomic neuropathy (AN) is a condition that results from damage to nerves that assist in organ and organ system functioning. This nerve damage disturbs signal processing between the autonomic nervous system and the brain. When your autonomic nerves are injured, your blood pressure, heart rate, perspiration patterns, bowel movement, bladder emptying, and digestion may be affected.
AN is often a complication associated with other medical conditions and diseases and certain medications. Your symptoms may vary based on the cause of your neuropathy and the location of your nerve damage.
Factors that might cause injury to the autonomic nerves include:
If you have diabetes, being overweight, elderly, and having high blood pressure and high cholesterol may further increase your risk of developing AN.
AN can affect many organs and cause an array of symptoms. Some early symptoms of AN include:
More progressive symptoms may affect specific organ functioning. These include:
Heart and Blood Vessels
Call for an appointment with your physician if you have symptoms of AN. Early diagnosis may improve your prognosis.
Your doctor will make a diagnosis based on your risk factors, observations during a physical examination, and results of medical tests. Your physician may conduct the following tests:
Treatments for AN target the damaged nerves and any underlying condition causing injury to the nerves. Thus, different treatments are available depending on the symptoms you are experiencing.
Digestive and gastrointestinal treatments include:
Bladder and urinary treatments include:
Sexual dysfunction treatments include:
Heart and blood pressure treatments include:
Abnormal sweating treatment includes:
The prognosis varies based on what is causing the nerve damage and how well it can be treated. In some cases, the nerves can repair themselves. In others, symptoms remain the same or even worsen despite treatment.
Addressing conditions that may cause neuropathy might help prevent its development.
Keep your blood sugar stable if you have diabetes. Eating a low-sugar and high-fiber diet might help regulate diabetes.
Stop smoking cigarettes. Talk to your physician about treatments available to assist in quitting.
Stop drinking alcohol. Seeking the services of a counselor may be helpful.
Incorporate exercise into your daily life to help you lose weight and manage certain health conditions.
Prevent high blood pressure by drinking plenty of fluids, exercising regularly, and eliminating stressors.
