Diabetic neuropathy is one of the most common and debilitating complications of diabetes. It occurs when high blood sugar damages nerves throughout the body — particularly in the legs and feet. It affects nearly 50% of people with diabetes at some point in their lives.
Types of Diabetic Neuropathy
Peripheral Neuropathy
The most common type, affecting nerves in the feet and legs (and sometimes hands and arms). It’s the leading cause of diabetes-related leg and foot amputations.
Autonomic Neuropathy
Damages the nerves that control automatic body functions like heart rate, blood pressure, digestion, and bladder function.
Proximal Neuropathy
Causes pain in the thighs, hips, buttocks, and legs, typically on one side of the body.
Mononeuropathy
Damage to a single, specific nerve — often causing sudden weakness or pain in the face, torso, hand, or leg.
Symptoms of Diabetic Neuropathy
- Tingling or burning sensations in feet and hands
- Numbness or reduced ability to feel pain or temperature
- Sharp, jabbing, or electric-like pain
- Extreme sensitivity to touch — even a light sheet can be painful
- Muscle weakness or loss of reflexes
- Balance problems and increased fall risk
- Digestive issues (if autonomic nerves are affected)
- Sexual dysfunction
- Bladder problems or urinary tract infections
What Causes Diabetic Neuropathy?
The primary cause is prolonged high blood sugar, which damages small blood vessels that supply oxygen and nutrients to nerves. Inflammation, inherited factors, and lifestyle choices like smoking and alcohol use all increase risk.
Diagnosing Diabetic Neuropathy
Your doctor may use a variety of tests including: physical and neurological exam, filament test (checking foot sensation), nerve conduction studies, and electromyography (EMG) to assess electrical activity in muscles.
Treatment Options
Blood Sugar Control
The single most important step is keeping blood sugar tightly controlled. This can slow the progression of neuropathy and sometimes reduce symptoms.
Pain Management
Medications for nerve pain include: pregabalin (Lyrica), gabapentin (Neurontin), duloxetine (Cymbalta), and tricyclic antidepressants. Topical treatments like capsaicin cream or lidocaine patches can also help.
Physical Therapy
Exercise improves blood flow to peripheral nerves and can reduce neuropathy symptoms while improving balance and strength.
Foot Care
People with peripheral neuropathy should inspect their feet daily for cuts, blisters, or sores — since reduced sensation means injuries can go unnoticed. Wear well-fitting shoes and see a podiatrist regularly.
