Polyneuropathy is the most common type and starts by affecting the longest nerves first, so symptoms typically begin in the feet. all the nerves in the body (polyneuropathy).several nerves (mononeuritis multiplex).You may need treatment to increase your blood pressure or, in rare cases, a pacemaker.įind out more about complications of peripheral neuropathy Different types of peripheral neuropathy Peripheral neuropathy may affect the nerves controlling the automatic functions of the heart and circulation system (cardiovascular autonomic neuropathy). This can lead to gangrene if untreated, and in severe cases may mean the foot has to be amputated.

If the underlying cause of peripheral neuropathy is not treated, you may be at risk of developing potentially serious complications, such as a foot ulcer that becomes infected. Some cases may improve with time if the underlying cause is treated, whereas in some people the damage may be permanent or may get gradually worse with time. The outlook for peripheral neuropathy varies, depending on the underlying cause and which nerves have been damaged. If you have other symptoms associated with peripheral neuropathy, these may need to be treated individually.įor example, treatment for muscle weakness may involve physiotherapy and walking aids. Nerve pain may be treated with prescribed medicines called neuropathic pain agents, as standard painkillers often do not work. Not all of the underlying causes of neuropathy can be treated.įor example, if you have diabetes, it may help to gain better control of your blood sugar level, stop smoking and cut down on alcohol. Treatment for peripheral neuropathy depends on the symptoms and underlying cause. People who are known to be at an increased risk of peripheral neuropathy may have regular check-ups so their nerve function can be assessed. a side effect of certain medicines or drinking too much alcohol.Peripheral neuropathy can also have a wide range of other causes. This type of nerve damage is known as diabetic polyneuropathy. Over time, the high blood sugar levels associated with diabetes can damage the nerves. In the UK diabetes (both type 1 and type 2) is the most common cause of peripheral neuropathy. Generally, the sooner peripheral neuropathy is diagnosed, the better the chance of limiting the damage and preventing further complications.įind out more about diagnosing peripheral neuropathy Causes of peripheral neuropathy You may be referred to hospital to see a neurologist, a specialist in health problems affecting the nervous system. It's also recommended that people at highest risk of peripheral neuropathy, such as people with diabetes, have regular check-ups.Ī GP will ask about your symptoms and may arrange some tests to help identify the underlying cause. a cut or ulcer on your foot that's not getting better.pain, tingling or loss of sensation in the feet.It's important to see a GP if you experience the early symptoms of peripheral neuropathy.

These symptoms are usually constant, but may come and go.

muscle weakness, especially in the feet.

burning, stabbing or shooting pain in affected areas.

numbness and tingling in the feet or hands.

The main symptoms of peripheral neuropathy can include:

autonomic nerves – responsible for regulating automatic functions of the body, such as blood pressure and bladder function.

motor nerves – responsible for controlling muscles.

sensory nerves – responsible for transmitting sensations, such as pain and touch.

It includes different types of nerves with their own specific functions, including: The peripheral nervous system is the network of nerves that lie outside the central nervous system (the brain and spinal cord). In the UK it's estimated almost 1 in 10 people aged 55 or over are affected by peripheral neuropathy. The symptoms depend on which nerves are affected.

Peripheral neuropathy develops when nerves in the body's extremities, such as the hands, feet and arms, are damaged.
