Is Peripheral Neuropathy the Same as PAD?

When you talk with your doctor about diabetes(Diabetes mellitus) is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both., you may hear a variety of medical terms, including peripheral artery diseasePeripheral artery disease (PAD) is a disease in which plaque builds up in the arteries that carry blood to your head, organs, and limbs. Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. (PADPeripheral Artery Disease, a potentially life threatening disease where plaque, like calcium, builds up along blood vessel walls, narrowing the arteries and reducing blood flow to the legs and feet.) and peripheral neuropathyThe most common type of neuropathy is peripheral neuropathy.  It affects the nerves in the hands, feet, legs, and arms. It generally starts in the feet, and it tends to start in both feet at once..

It’s easy to confuse these “peripheral conditions” because both cause burning or painful discomfort in the feet or legs. As you advocate for your or a loved one’s health, you want to know the correct diagnosis and term. That way you can do additional research and know the right type of doctor for a second opinion.

So what is the difference between these two serious conditions?

What is peripheral neuropathy?

Your peripheral nervous system is the critical connection between your central nervous system and the rest of your body. Peripheral nerves tell you how you feel — cold, hot, tingly, prickly, numb or weak. But what happens if these nerves are damaged or destroyed?

Peripheral neuropathyPeripheral neuropathy is a condition that develops as a result of damage to the peripheral nervous system. is a disease that results from diminished or malfunctioning peripheral nerves. According to Johns Hopkins, “Some people inherit the disorder from their parents. Others develop it because of an injury or another disorder,” which can include chemotherapy, infections, traumatic injuries and more. However, diabetes is one of the most common causes.⁴⁵

Peripheral neuropathy can mask PAD symptoms and delay diagnosis, according to Harvard Health Pubhlishing. Women are particularly at risk as they are less likely to report pain.

Know the symptoms  

Estimates show that neuropathy will affect about 25% to 30% of Americans. The condition affects people of all ages; however, older people are at increased risk. About 8% of adults over 65 years of age report some degree of neuropathy, according to the Cleveland Clinic.

The most common peripheral neuropathy symptoms include:

• Gradual onset of numbness and weakness in legs
• Constant or shooting/stabbing pain
• Changes in sensation — from an inability to feel pain, pressure, temperature or touch to extreme sensitivity to touch and severe pain, especially at night
• Pain during casual activities
• Tripping, stumbling, lack of coordination and balance problems
• Muscle weakness and atrophy

What is PAD?

While peripheral neuropathy is a nervous system condition, PAD is a condition of the arteriesArteries are blood vessels that carry blood to your heart and other parts of your body.. It’s characterized by narrowed, hardened arteries in the legs, limiting blood flow to the legs and feet.

Common risk factors for PAD are increasing age, diabetes, kidney diseaseA disease that impairs the kidneys’ ability to filter waste products and extra water from the blood. and smoking. PAD has a range of general symptoms:

• Cold toes or feet
• Dry, discolored skin
• Pain while walking
• Nighttime leg pain
• Painful, heavy legs
• Numbness or burning sensations
• Wounds that won’t heal
• GangreneGangrene is dead tissue, caused by poor blood flow to part of your body. Gangrene can occur on the skin or in muscles or organs. Peripheral artery disease is a known cause of gangrene. or black tissue

Peripheral neuropathy can mask PAD symptoms and delay diagnosis, according to Harvard Health Publishing. Talk to your primary care physician (PCP) if you’re having recurring pain. Describe the pain in detail to help get a proper diagnosis.
