What Diabetic Neuropathy Is
Diabetic neuropathy refers to a group of nerve disorders that occur in people with diabetes, affecting sensory, motor, and autonomic nerves. Over time, high glucose levels damage blood vessels and the metabolic pathways that support nerves, leading to progressive dysfunction.
The American Diabetes Association describes diabetic neuropathies as the most prevalent chronic complications of diabetes, encompassing diffuse forms like DSPN (symmetrical, length-dependent sensorimotor polyneuropathy due to chronic hyperglycemia and cardiovascular risks) and autonomic neuropathies affecting cardiovascular, gastrointestinal, or urogenital systems.
Main Types of Diabetic Neuropathy
Peripheral neuropathy:
The most common form. It affects the feet and legs first and sometimes the hands, causing pain, tingling, numbness, or loss of sensation in a “stocking-glove” pattern.
Autonomic neuropathy:
Affects automatic body functions such as heart rate, blood pressure, digestion, bladder control, and sexual function.
Proximal (radiculoplexus) neuropathy and focal neuropathies:
Causes sudden pain or weakness in specific areas such as the thighs, hips, chest wall, or eye muscles.
Common Symptoms
Symptoms depend on which nerves are affected, but may include:
• Burning, stabbing, or electric-like pain
• Numbness or tingling in feet or hands
• Reduced ability to feel heat, cold, or injuries
• Balance and walking difficulty
• Foot ulcers that may not cause pain
• Digestive issues such as nausea, bloating, or diarrhea
• Dizziness when standing up (orthostatic hypotension)
• Bladder control issues
• Sexual dysfunction in men and women
Loss of protective sensation is especially dangerous because it increases the risk of unnoticed injuries, infections, and amputations.
Causes and Risk Factors
The primary cause is prolonged high blood sugar, which damages nerves and the small blood vessels that supply them.
Additional risk factors include:
• Long duration of diabetes
• Poor glucose control
• High cholesterol
• High blood pressure
• Kidney disease
• Smoking
• Obesity
• Heavy alcohol use
The more risk factors present, the faster nerve damage can progress.
Prevention and Self-Care Strategies
Preventing or slowing diabetic neuropathy focuses on protecting nerves through comprehensive diabetes management:
• Keep blood sugar levels within the target range using medication, nutrition, and physical activity
• Maintain healthy cholesterol and blood pressure
• Avoid smoking and limit alcohol
• Maintain a healthy weight
• Perform daily foot checks for cuts, redness, or swelling
• Wear comfortable, well-fitting shoes
• Schedule regular podiatry visits to prevent ulcers and infections
Good foot care is critical to reducing the risk of complications.
Treatment Basics
Good blood glucose management is the most important treatment to slow nerve damage and may improve symptoms, especially in the early stages.
Painful diabetic neuropathy can be managed with:
• Certain antidepressants or anticonvulsants
• Topical treatments such as capsaicin or lidocaine
• Physical therapy
• Exercise programs
• Non-drug therapies such as TENS (nerve stimulation)
Treatment plans are personalized based on symptom severity, medical history, and patient goals.
Statistics and Key Facts
• Over 50% of people with diabetes develop some form of neuropathy
• About 25% experience painful diabetic peripheral neuropathy
• Neuropathy increases the risk of foot ulcers and amputations
• Early management dramatically reduces complications
