Also known as: Neuropathy - metabolic
- A problem with the body's ability to use energy, often due to a lack of enough nutrients (nutritional deficiency)
- Dangerous substances (toxins) that build up in the body
- Those with damage to the kidneys or eyes
- Those with poorly controlled blood sugar
- Low blood sugar (hypoglycemia)
- Kidney failure
- Severe infection throughout the body (sepsis)
- Thyroid disease
- Difficulty feeling in any area of the body
- Difficulty using the arms or hands
- Difficulty using the legs or feet
- Difficulty walking
- Pain, burning feeling, pins and needles feeling, or shooting pains in any area of the body (nerve pain)
- Weakness in the face, arms, legs, or other area of the body
- Decreased feeling (may affect touch, pain, vibration, or position sensation)
- Reduced reflexes (most common in the ankle)
- Muscles becoming smaller (atrophy)
- Muscle twitches (fasciculations)
- Muscle weakness
- Loss of movement (paralysis)
- Blood tests
- Electrical test of the muscles (EMG)
- Electrical test of nerve conduction
- Injury to feet
- Trouble walking
- Avoid excess alcohol use.
- Eat a balanced diet.
- Visit the doctor regularly to find metabolic disorders before neuropathy develops.
Metabolic neuropathies are nerve disorders that occur with diseases that disrupt the chemical processes in the body
Nerve damage can be caused by many different things. Metabolic neuropathy may be caused by:
Diabetes is one of the most common causes of metabolic neuropathies. People who are at the highest risk of nerve damage (diabetic neuropathy) from diabetes include:
Other common causes of metabolic neuropathies include:
Some metabolic disorders are passed down through families (inherited), while others develop due to various diseases.
These symptoms occur because nerves cannot send proper signals to and from your brain:
Usually, these symptoms start in the toes and feet and move up the legs, eventually affecting the hands and arms.
Exams and Tests
An exam may show:
Tests used to detect most metabolic neuropathies:
For most metabolic neuropathies, the best treatment is to correct the metabolic problem.
Vitamin deficiencies are treated with diet or injections. Abnormal blood sugar or thyroid function may need medication to correct the problem. Alcoholic neuropathy is treated with alcohol abstinence.
In some cases, pain is treated with medications that reduce abnormal pain signals from the nerves (duloxetine, gabapentin, pregabalin). Lotions, creams, or medicated patches can provide relief in some cases.
Clinical trials of new medications include antioxidants, neuroprotectants, insulin-like drugs, and aldose reductase inhibitors.
Weakness is often treated with physical therapy. You may need to learn how to use a cane or walker if your balance is affected. You may need special braces on the ankles to walk better.

The outlook mainly depends on the cause of the disorder. In some cases, the problem can easily be treated. In other cases, the metabolic problem cannot be controlled, and nerves may continue to become damaged.
Maintaining a healthy lifestyle can reduce the risk of neuropathy.
If you already have a metabolic problem, regular doctor visits can help control the problem and reduce the chance of further nerve damage.
Patients who already have metabolic neuropathy can reduce the risk of some complications. A foot doctor (podiatrist) can teach you how to inspect your feet for signs of injury and infection. Proper fitting shoes can lessen the chance of skin breakdown in sensitive areas of the feet.
