Diabetes Overview - Complications
Neuropathy
Diabetes can cause nerve damage, called neuropathy - a loss of sensation in your feet. Many people suffer from neuropathy caused by their diabetes and there are different types of neuropathy depending on which type of nerve has been affected.

Symptoms 
Tingling -
one of the most common symptoms, often described as pins and needles. This can affect the toes and feet and sometimes the lower leg as well

Numbness -
the loss of feeling in the feet

Pain -
some people have very severe pain from neuropathy. This is usually felt in both feet - sometimes extending up both legs - or one or both thighs. People often feel a burning sensation, pins and needles and shooting pains. Contact with the skin is very uncomfortable so that the lightest touch, even from bed clothes is unpleasant.
Diagnosis
There are some other medical conditions which can cause similar symptoms to diabetic neuropathy but which need different treatment. For example, as a result of poor circulation, you may also suffer from cramp and pain in your legs and/or feet, which need different treatment.

It is very important that you are examined by a diabetes specialist or by a neurologist to confirm a diagnosis of neuropathy.

If diabetic neuropathy is confirmed it is important to remember that:

• the worst of the pain will end although this can take 6 to 18 months, in the meantime there are many treatments for pain
• better diabetes control should eventually help the pain
• recovery is usually complete with the symptoms eventually disappearing
• the pain, no matter how bad, does not lead to amputation or paralysis

 
Sensory neuropathy
Sensory neuropathy is the most common type of neuropathy affecting people with diabetes and mainly affects the nerves in the feet and the legs.

Occasionally people also develop this type of neuropathy in their arms and hands.

Sensory nerves carry messages of touch, temperature, pain and other sensations from the skin, bones and muscles to the brain. The main danger of sensory neuropathy is loss of feeling in the feet, especially if you do not realise that this has happened.

This is because you may not notice minor injuries, which may be caused by:

• nails or stones in shoes
• friction from badly fitting shoes
• burns from radiators or hot water bottles
• walking around barefoot.

If ignored minor injuries may get worse and cause infections or ulcers.

People with diabetes are more likely to be admitted to hospital with a foot ulcer than with any other complication of diabetes.
 
What causes sensory neuropathy?
It is still not known exactly how diabetes damages the nerves. One possibility is that nerve damage is a result of damage to the small blood vessels, which prevents essential nutrients reaching the nerves. The nerve fibres then become damaged or disappear altogether.

Good blood glucose control can reduce the risk of developing neuropathy.
 
Treatment
Although neuropathy cannot be cured, there are now many treatments available and with the help of your diabetes team, symptoms can be relieved and your quality of life greatly improved. Treating the pain from diabetic neuropathy takes patience and persistence. The most important thing to remember is to take the treatment regularly even if the pain has lessened. Preventing pain is much easier than waiting until the pain has returned and then treating it.

The pain can be treated in a number of different ways -simple painkillers, creams and even some tablets that are usually used for treating depression as they have a calming effect on the nerves. They also have the added advantage of improving the quality of improving the quality of sleep. Good control of your diabetes does reduce the progression of the nerve damage, so good diabetes control is the key to reducing the risk of neuropathy.
 
And finally...
The most important thing to remember is to protect the feet from injury, which can occur in people who are unaware that they have lost some feeling in their feet. This is why the annual medical check-up is so important - it allows your diabetes team to spot any problems that you may be unaware of. And remember: seek help as soon as possible if any problems arise.
