Neuropathy is a condition that results from dysfunction or damage to the nerves outside the brain and spinal cord. It signifies a problem in the peripheral nervous system. Also known as peripheral neuropathy, the condition causes numbness, weakness, pain, and tingling in the affected areas. Symptoms usually begin in the hands and feet but can affect other body areas and functions.
The peripheral nerve system consists of three nerve types, each playing a vital role in keeping the body healthy. They help ensure proper body function and include the sensory, motor, and autonomic nerves.
Sensory nerves carry messages between the five senses and the brain through the spinal cord. Motor nerves carry messages from the brain to the muscles. Autonomic nerves deal with functions beyond the individual's control, such as breathing, heart rate, blood pressure, digestion, and sweating.
Neuropathy occurs when neurons or nerve cells are destroyed or damaged. It disrupts the communication between the neurons and the brain. There are different causes of neuropathy, including:
Diabetes - the most common cause of neuropathy
Trauma or injuries - caused by accidents, falls, sporting activities, and other incidents
Infections and autoimmune disorders
Health conditions - such as hypothyroidism and kidney and liver disorders
Medications - including some antibiotics and anti-seizure drugs
Exposure to toxins - including heavy metals and industrial solvents
Inherited disorders
Vascular disorders
Chronic alcoholism
Abnormal vitamin levels
Neuropathy is a common condition that affects individuals of all ages but is most common among the elderly. Age, diabetes, obesity, high blood pressure, and high cholesterol increase the risk of neuropathy.
Experts estimate that about 25 to 30 percent of Americans will suffer from neuropathy at some point. Individuals in certain professions have a higher likelihood of developing the condition. They include those who perform activities that require repetitive movements.
Symptoms of the condition depend on the location and type of nerves affected. Some symptoms appear suddenly (acute neuropathy), while others develop gradually over time (chronic neuropathy). Common symptoms include:
Tingling sensation or numbness
Sharp, throbbing, stabbing, or burning pain
Loss of coordination or falling
Muscle weakness or difficulty moving the limbs or walking
Changes in sensation, including extreme sensitivity, inability to feel anything, or severe pain
Inability to feel things in the hands or feet
Abnormal heart rate or low blood pressure usually causes fainting or dizziness when standing up
Muscle cramps, spasms, or twitching
Paralysis or inability to move a body part
Loss of muscle tone and muscle control
Excessive sweating or lack of sweat, based on the temperature or exertion
Weight loss
Problems with urination, digestion, and bowel functions
Problems with sexual function
If you have neuropathy, you should begin treatment immediately. Some neuropathies are easier to treat. In some cases, the condition is incurable, but it is possible to manage the symptoms. Progression of the disease will vary greatly depending on the type, but prompt treatment is vital. Long-term results will depend on the cause of the neuropathy.
