Living with diabetes means paying close attention to your health every day. For nearly 11% of Americans, it’s a journey that requires a lifelong commitment. While there’s no cure for diabetes, it can be successfully managed with the right combination of lifestyle habits, monitoring and medication.

Neuropathy refers to nerve damage that can cause pain, numbness or weakness, often interfering with everyday life. Diabetic neuropathy is one of the most common forms, affecting up to half of people with diabetes — often without noticeable symptoms at first. While neuropathy can have many causes, diabetes is the most common.

Understanding how diabetic neuropathy develops and catching it early can make a meaningful difference in protecting your mobility, comfort and overall well-being. Our expert foot and ankle surgeon, Matthew Villani, DPM, FACFAS, explains what you need to know about diabetic neuropathy so you don’t miss the warning signs.

Helping You Understand Diabetic Neuropathy

“Over time, consistently high blood sugar can quietly damage your nerves and lead to diabetic neuropathy,” explains Dr. Villani. “The condition most commonly affects the feet, legs and hands, but it can also impact internal systems such as digestion, heart rate and bladder function. That’s because nerves play a role in nearly every function your body performs.”

There are multiple forms of diabetic neuropathy, including:

  • Autonomic neuropathy, which impacts involuntary functions like digestion and blood pressure
  • Focal neuropathy, which involves damage to a single nerve and may appear suddenly
  • Peripheral neuropathy, which affects nerves outside the spinal cord, like the legs and feet, and is the most common type
  • Proximal neuropathy, often causing pain in the hips, thighs or buttocks
  • Sweat Regulation: Excessive (hyperhidrosis) or reduced sweating (anhidrosis) leading to body temperature regulation issues, which can cause patients with neuropathy increased susceptibility to ulceration

If you have diabetes, it’s important to understand these signs and symptoms, so you can seek care sooner and protect your long-term health.

Why Diabetic Neuropathy Often Goes Undetected

One of the biggest challenges with diabetic neuropathy is that symptoms may begin subtly or not cause noticeable pain at all. Loss of feeling, especially in the feet, can make it easy not to notice injuries and delay care.

“Because nerve damage tends to progress gradually, people may attribute symptoms to aging, circulation issues or unrelated conditions,” shares Dr. Villani. “Unfortunately, waiting can raise the risk of complications such as infections, ulcers and mobility loss.”

Routine screenings and awareness are essential tools for prevention.

Diabetic Neuropathy FAQs

What are the early symptoms of diabetic neuropathy?

Symptoms vary depending on the type and severity of nerve damage, but commonly include:

  • Burning, sharp or shooting pain
  • Muscle weakness or balance issues
  • Numbness or reduced ability to feel temperature or pain
  • Sensitivity to touch
  • Tingling or “pins and needles” sensations

Not everyone experiences all of these symptoms, which is why routine monitoring is so important.

What warning signs should I never ignore?

Some changes require prompt medical attention, especially for those living with diabetes:

  • Difficulty with urination or sexual function
  • Foot sores, blisters or ulcers
  • Infections that heal slowly
  • Lightheadedness or dizziness when standing
  • Sudden changes in digestion or bowel habits

Even if these symptoms seem unrelated, they may point to nerve involvement. Don’t delay seeking care so you can get answers and treatment.

Who is at higher risk for developing diabetic neuropathy?

The risk of diabetic neuropathy increases with:

  • Excess body weight
  • Having diabetes for many years
  • High blood pressure or cholesterol
  • Kidney disease
  • Older age
  • Peripheral vascular disease
  • Poorly controlled blood sugar levels
  • Smoking or heavy alcohol use

Making lifestyle changes can help improve some risk factors, while others require close monitoring and support from your care team.

The Role of Foot Care and Early Detection

Often, your feet are the first to show early signs of nerve damage. “Regular foot exams allow providers to assess circulation, sensation and skin integrity, helping detect neuropathy before it leads to serious complications,” says Dr. Villani.

Early diagnosis helps:

  • Improve long-term outcomes
  • Preserve mobility and independence
  • Reduce the risk of ulcers and infections
  • Slow or stop the progression of nerve damage

Including podiatric care in your diabetes management plan is an essential step toward prevention.

Managing and Preventing Diabetic Neuropathy

While there’s no cure for diabetic neuropathy, proactive care can greatly reduce symptoms and progression. Your daily habits play a powerful role in nerve health, including:

  • Following a diabetic-friendly diet
  • Keeping all routine medical appointments
  • Limiting alcohol intake
  • Maintaining healthy blood sugar, blood pressure and cholesterol levels
  • Staying physically active with safe, regular movement
  • Taking medications consistently as prescribed

Taking these actions can support both nerve function and your overall quality of life.
