What are the two nervous systems?
The body has two nervous systems: the central nervous system and the peripheral nervous system. The central nervous system is composed of the brain and spinal cord. The peripheral nervous system includes the nerves that branch out from the brain and spinal cord and extend to other parts of your body (your arms, legs, face, chest, and abdomen to name a few). Nerve damage generally refers to the peripheral nervous system.

What are the complications of peripheral neuropathy?
Peripheral neuropathy can give rise to the following complications: 1 Loss of sensation: Nerve damage can cause gradual numbness in certain parts of your body, such that you are unable to feel temperature changes or pain. As a result, you become more vulnerable to burns and skin trauma that the body is unable to detect at the time of its occurrence. 2 Falls. Nerve damage often renders your body too weak, numb, and out of balance, which is associated with an increased incidence of falling accidents. 3 Infection: People with peripheral neuropathy, particularly those with prolonged diabetes, experience reduced sensitivity in areas of the body that are susceptible to injuries such as the feet. Because they remain unaware of the pain and irritation on account of the numbness, wounds, and injuries often go untreated for a long time, paving the way for ulcers and infections. In addition, people with prolonged diabetes already have compromised wound healing ability. [18]
