Neuropathy is a condition that affects the nerves of the body, causing symptoms such as numbness, tingling, and weakness. It is a disorder that arises due to damage or dysfunction in the nerves, which can be caused by a variety of underlying conditions, such as diabetes, infections, autoimmune disorders, alcoholism, and certain medications. The damage can occur in the peripheral nerves, which connect the brain and spinal cord to the rest of the body, or in the autonomic nerves, which control involuntary bodily functions such as blood pressure, heart rate, and digestion.
