G60-G64: Polyneuropathies and other disorders of the peripheral nervous system

G62: Other polyneuropathies

Polyneuropathies are a group of conditions that involve damage or disease affecting peripheral nerves, which are those outside of the brain and spinal cord. This can lead to problems with sensation, movement, or organ function, depending on the specific nerves that are affected. Common symptoms can include numbness or tingling, muscle weakness, and pain, usually starting in the hands and feet. Polyneuropathies can develop due to several causes, including diabetes, certain infections, nutritional deficiencies, or exposure to toxins. Disease progression varies depending on the cause, but symptoms may slowly worsen over time as more nerves are affected. While some forms of polyneuropathy can affect the entire body, others may target specific regions or systems.
