Nerve damage, medically referred to as neuropathy, occurs when nerves are injured or impaired, disrupting their ability to transmit signals between the brain, spinal cord, and the rest of the body. It can result from conditions such as diabetes, infections, physical trauma, autoimmune disorders, exposure to toxins, or vitamin deficiencies. Symptoms vary depending on the type of nerves affected and may include numbness, tingling, burning pain, muscle weakness, loss of coordination, or heightened sensitivity to touch. In some cases, autonomic nerve damage can affect internal functions such as digestion, blood pressure regulation, or heart rate. Treatment focuses on addressing the underlying cause, relieving symptoms, and preventing further nerve injury, often through medications, physical therapy, nutritional support, and lifestyle modifications.
