The number one risk factor today for peripheral neuropathy is having uncontrolled blood sugar levels caused by type II diabetes over a prolonged period of time.
Diabetes is the number one cause of peripheral neuropathy today and is attributable to causing over one third of all new cases of neuropathy.
Diabetes is called the silent killer because not only does high blood sugar damage internal organs such as the liver and kidneys, but it also damages nerve endings and impedes the proper transmission of electrical signals from the central nervous system to the peripheral nervous system.
Another risk factor for peripheral neuropathy is how much deep water fish a person eats in his diet. This is because heavy metal poisoning is another major cause of peripheral neuropathy.
Deep water fish such as blue fin tuna contain high amounts of mercury, due to rising levels of mercury in the open ocean caused by pollution.
Another risk factor that is highly correlated with peripheral neuropathy is age. Damage to nerves does not happen overnight and it can take years for nerves to be impaired enough to cause symptoms of peripheral neuropathy.
In addition, alcoholism is another great risk factor for peripheral neuropathy. Like high blood glucose, alcohol in the blood is a poison to our nerves and can cause nerve damage over a period of many years.
