Diabetes, PVD, and Your Feet: A Dangerous but Preventable Connection

If you have diabetes, you already know how important it is to monitor your blood sugar levels. But did you know that diabetes also affects your blood vessels, especially in your legs and feet?

This condition is called Peripheral Vascular Disease (PVD)—and when combined with diabetes, it can have serious consequences for your foot health.

What Is Peripheral Vascular Disease (PVD)?

PVD is a circulation problem where narrowed or blocked blood vessels reduce blood flow to the limbs—most commonly the legs and feet. It’s caused by a buildup of plaque (fat and cholesterol) in the arteries, a process called atherosclerosis.

How Are Diabetes and PVD Connected?

People with diabetes are more likely to develop PVD—and they may develop it earlier and more severely than those without diabetes. Here’s why:

• High blood sugar damages blood vessels, making them more prone to plaque buildup.

• Diabetes often leads to high cholesterol and high blood pressure, which increase the risk of vascular disease.

• Nerve damage (neuropathy) from diabetes can mask the warning signs of poor circulation.

This means someone with diabetes and PVD might not feel pain or notice a problem until it becomes serious—like an ulcer or even a foot infection.

 Why It’s a Big Deal for Your Feet

Reduced blood flow from PVD means:

• Cuts and wounds heal more slowly

• There’s a higher risk of infection

• Minor foot injuries can turn into ulcers or gangrene

• In severe cases, amputation may be necessary

Foot complications from diabetes and PVD are one of the leading causes of non-traumatic lower limb amputations in the U.S.

 Warning Signs to Watch For

If you have diabetes, be alert for these signs of PVD in your feet or legs:

• Cold feet or toes

• Cramping or pain when walking (called claudication)

• Numbness or tingling

• Weak or absent pulse in your feet

• Sores, ulcers, or wounds that don’t heal

• Skin discoloration or shiny skin

 How Is It Diagnosed?

Your doctor may use tests like:

• Ankle-Brachial Index (ABI) – compares blood pressure in your ankle and arm

• Doppler ultrasound – shows blood flow in your legs

• Angiography – provides images of blood vessels

 How to Protect Your Feet (and Arteries)

Managing both diabetes and PVD requires a proactive approach:

1. Control Blood Sugar

• Keep blood glucose levels in your target range

• A1C tests help monitor long-term control

2. Quit Smoking

• Smoking severely worsens circulation and speeds up PVD

3. Check Your Feet Daily

• Look for cuts, blisters, redness, or swelling

• Use a mirror or ask for help if needed

4. Wear Proper Footwear

• Supportive, well-fitting shoes reduce pressure and risk of injury

5. Stay Active

• Walking and gentle exercise improve circulation

6. See a Podiatrist Regularly

• Professional foot exams are essential—even if you don’t feel symptoms

Final Thoughts

Diabetes and PVD create a silent but dangerous threat to your feet. The good news? With early detection and proper care, most complications are preventable. It all starts with awareness, daily foot care, and regular checkups. If you're noticing changes in your feet or just want a preventative checkup, schedule an appointment with Dr. Gireesh Reddy or Dr. Sirisha Pokala at Restore Foot & Ankle Specialists by calling (469) 573-3427 or by booking an appointment online.
