What is neuropathy?
Neuropathy is the disease of the nervous system. Neuropathy is a disturbance in the function of a nerve or particular group of nerves. Many people who have had diabetes for a while have nerve damage. The three major forms of nerve damage are: peripheral neuropathy, autonomic neuropathy, and mononeuropathy. The most common form is peripheral
neuropathy, which mainly affects the feet and legs.
Neuropathy can lead to disability, amputation, decreased ambulation as well as foot and leg ulceration because of loss or damage to nerves which feel sensation in the lower limbs. Another reason for the disability is due to the changes that can occur in the biomechanics of feet and legs, leading to an increased risk of ulcers. A diabetic person that has neuropathy increases their risks of amputation of an extremity 2 fold.
Peripheral neuropathy is a general term referring to disorders of peripheral nerves. The peripheral nervous system is made up of the nerves that branch out of the spinal cord to all parts of the body. Peripheral nerve cells have three main parts: cell body, axons, and dendrites. Any part of the nerve can be affected, but damage to axons is most common. The axon transmits signals from nerve cell to nerve cell. Most axons are surrounded by a substance called myelin, which facilitates signal transmission. Peripheral neuropathy can be associated with poor nutrition, a number of diseases, and pressure or trauma. Many people suffer from the disorder without ever identifying the cause.
Mononeuropathy involves damage or destruction of an isolated nerve or nerve group. It is a type of peripheral neuropathy (damage to nerves outside the brain and spinal cord). Mononeuropathy is most often caused by damage to a local area resulting from injury or trauma, although occasionally systemic disorders may cause isolated nerve damage (as with mononeuritis multiplex). The usual causes are direct trauma, prolonged pressure on the nerve and compression of the nerve by swelling or injury to nearby body structures. The damage includes destruction of the myelin sheath (covering) of the nerve or of part of the nerve cell (the axon). This damage slows or prevents conduction of impulses through the nerve.
Autonomic neuropathy effect nerves of body parts that we cannot consciously control. The digestive system is most often affected, especially the intestine and stomach, blood vessels and heart, urinary system. It can affect the nerves that control you tiny muscles of the eyes and sex organs. It can also affect the return of normal blood sugars when an episode of hypoglycemia occurs. This type of nerve damage frequently results in damage that causes the inability to sense low blood sugars. To prevent autonomic neuropathy, you need to continuously keep your blood glucose levels well controlled.
In all neuropathy and neuropathic pain, there is abnormal conduction of nerve impulses from the input (usually peripheral in the extremities) to the spinal cord and brain. The pain of neuropathy is a result of the abnormal processing of nerve impulses that originate in these peripheral nerves. The terms neuropathy and peripheral neuropathy are often used interchangeably to describe the same process. Neuropathy can cause strange and extremely unpleasant sensations to arise in the affected area, including paresthesia (tingling or numbness), causalgia (burning sensations), and dysesthesia (unpleasant, burning, crawling, itchy, tingling or numb sensations)--or just plain pain.
Pain associated with neuropathy can be very intense and may be described as cutting, stabbing, crushing, burning, shooting, gnawing, or grinding. In some cases, a nonpainful stimulus (such as a feather drawn across the skin) may be perceived as excruciating, or pain may be felt even in the absence of a stimulus. If a problem with the motor nerve has continued over a length of time, muscle shrinkage (atrophy), or lack of muscle tone, may be noticeable. Autonomic nerve damage can also occur and is most noticeable when an individual stands upright and experiences difficulties such as light-headedness or changes in blood pressure. Other indicators of autonomic nerve damage are lack of sweat, tears, and saliva; urinary retention; and impotence. In some cases, heart beat irregularities and respiratory problems can develop.
Neuropathy often results in numbness, abnormal sensations called dysthesias and allodynias that occur either spontaneously or in reaction to external stimuli, and a characteristic form of pain, called neuropathic pain or neuralgia, that is qualitatively different from the ordinary nociceptive pain one might experience from stubbing a toe or hitting a finger with a hammer. Neuropathic pain is usually perceived as a steady burning and/or "pins and needles" and/or "electric shock" sensations. The difference is due to the fact that "ordinary" pain stimulates only pain nerves, while a neuropathy often results in the firing of both pain and non-pain (touch, warm, cool) sensory nerves in the same area, producing signals that the spinal cord and brain do not normally expect to receive.
