Understanding Diabetic Neuropathy

Diabetic neuropathy is a type of nerve damage that can occur as a complication of diabetes. High blood sugar (glucose) can injure nerves throughout your body, but diabetic neuropathy most often damages nerves in your legs and feet. Depending on the affected nerves, symptoms can range from pain and numbness in your legs and feet to problems with your digestive system, urinary tract, blood vessels, and heart. This quiz covers key aspects of its causes, types, symptoms, and management.

Types of Diabetic Neuropathy

There are four main types of diabetic neuropathy. It’s possible to have more than one type.

Peripheral neuropathy: This is the most common type. It affects the feet and legs first, followed by the hands and arms. Symptoms are often worse at night.
Autonomic neuropathy: This type affects the autonomic nervous system, which controls your heart, bladder, stomach, intestines, sex organs, and eyes. It can cause issues with blood pressure, digestion (gastroparesis), and bladder control.
Proximal neuropathy (diabetic amyotrophy): This type affects nerves in the thighs, hips, or buttocks. It usually affects one side of the body and is more common in older adults with type 2 diabetes.
Mononeuropathy (focal neuropathy): This involves damage to a single, specific nerve in the face, torso, or leg. It often comes on suddenly and can cause severe pain but typically improves on its own over a few weeks or months.

Key Takeaway: The most critical factor in preventing or slowing the progression of diabetic neuropathy is strict, consistent blood sugar control.

Common Symptoms and Signs

Symptoms vary based on the type of neuropathy and which nerves are affected. Common signs of peripheral neuropathy include:

Numbness, tingling, or a “pins and needles” sensation.
Burning pain, often worse at night.
Loss of sensation, which increases the risk of foot injuries going unnoticed.
Extreme sensitivity to touch.
Muscle weakness and difficulty walking.

Diagnosis and Treatment Approaches

Diagnosis usually involves a physical exam, a review of symptoms, and tests like a comprehensive foot exam to check for sensation. Nerve conduction studies or electromyography (EMG) may also be used. While there is no cure, treatment focuses on three areas: slowing the progression of the disease, relieving pain, and managing complications.

The Importance of Foot Care

Because peripheral neuropathy can cause a loss of feeling in the feet, minor injuries like cuts or blisters can go unnoticed and develop into serious infections or ulcers. Daily foot inspection, proper footwear, and regular checkups with a healthcare provider or podiatrist are essential for prevention.

Risk Factors and Prevention

Anyone with diabetes can develop neuropathy, but several factors increase the risk, including poor blood sugar control, a long history of diabetes, being overweight, smoking, and having high blood pressure or high cholesterol. The best prevention strategy is a healthy lifestyle and tight management of blood glucose levels.

Managing Neuropathic Pain

Pain from diabetic neuropathy can be debilitating. While over-the-counter pain relievers may not be effective, several prescription medications can help. These include certain antidepressants (like duloxetine), anti-seizure drugs (like pregabalin and gabapentin), and sometimes topical treatments or other therapies.

Frequently Asked Questions

Can diabetic neuropathy be reversed?

While significant nerve damage cannot be fully reversed, managing blood sugar levels can prevent further damage and, in some cases, may lead to a modest improvement in symptoms or nerve function, especially in the early stages.

What is the first sign of diabetic neuropathy?

For most people, the first symptom is often a gradual onset of numbness, tingling, or a “pins-and-needles” feeling in the toes or feet. This sensation can then spread up the legs.

How is autonomic neuropathy different from peripheral neuropathy?

Peripheral neuropathy affects the nerves that control sensation and movement, primarily in the limbs (hands and feet). Autonomic neuropathy affects the nerves that manage involuntary body functions like heart rate, blood pressure, digestion, and bladder function.

Why is foot care so critical for people with diabetic neuropathy?

Loss of sensation means a person might not feel a small cut, blister, or sore on their foot. In someone with diabetes, poor circulation can impair healing, allowing these minor injuries to become severe infections or non-healing ulcers, which are a leading cause of amputations.
