Autonomic neuropathy
Neuropathy - autonomic; Autonomic nerve disease
Autonomic neuropathy is a group of symptoms that occur when there is damage to the nerves that manage every day body functions. These functions include blood pressure, heart rate, sweating, bowel and bladder emptying, and digestion.
Causes
Autonomic neuropathy is a group of symptoms. It is not a specific disease. There are many causes.
Autonomic neuropathy involves damage to the nerves that carry information from the brain and spinal cord. The information is then carried to the heart, blood vessels, bladder, intestines, sweat glands, and pupils.
Autonomic neuropathy may be seen with:
- Alcohol abuse
-
Diabetes
(diabetic neuropathy)

Nerve damage that occurs in people with diabetes is called diabetic neuropathy. This condition is a complication of diabetes.
- Disorders involving scarring of tissues around the nerves

Exams and Tests
Signs of autonomic nerve damage are not always seen when your doctor examines you. Your blood pressure or heart rate may change when lying down, sitting, or standing.
Special tests to measure sweating and heart rate may be done. This is called autonomic testing.
Other tests depend on what type of symptoms you have.
Treatment
Treatment to reverse nerve damage is most often not possible. As a result, treatment and self-care are focused on managing your symptoms and preventing further problems.
Your health care provider may recommend:
- Extra salt in the diet or taking salt tablets to increase fluid volume in blood vessels
- Fludrocortisone or similar medicines to help your body retain salt and fluid
- Medicines to treat irregular heart rhythms
- Pacemaker
- Sleeping with the head raised
-

Outlook (Prognosis)
How well you do will depend on the cause of the problem and if it can be treated.
When to Contact a Medical Professional
Call your provider if you have symptoms of autonomic neuropathy. Early symptoms might include:
- Becoming faint or lightheaded when standing
- Changes in bowel, bladder, or sexual function
- Unexplained nausea and vomiting when eating
Early diagnosis and treatment may control symptoms.
Autonomic neuropathy may hide the warning signs of a heart attack. Instead of feeling chest pain, if you have autonomic neuropathy, during a heart attack you may only have:
- Sudden fatigue
- Sweating
- Shortness of breath
- Nausea and vomiting
Prevention
Prevent or control associated disorders to reduce the risk of neuropathy. For example, people with diabetes should closely control blood sugar levels .
Control blood sugar levels
Hyperglycemia - control; Hypoglycemia - control; Diabetes - blood sugar control; Blood glucose - managing
