Many people think this way. Peripheral arterial disease (PAD) is often linked with diabetes, so people without diabetes tend to ignore the warning signs.

Yes, you can absolutely have PAD without diabetes. Smoking, high blood pressure, high cholesterol, age and family history can all block the leg arteries — even if your sugar levels are perfectly normal. In fact, a large number of people with PAD do not have diabetes at all.

This guide explains what causes PAD without diabetes, the signs to watch for, how it is diagnosed, and how it can be treated — often without big surgery.

What Is PAD?

Peripheral arterial disease (PAD) is a condition in which the arteries carrying blood to the legs and feet become narrow or blocked.

The most common reason is atherosclerosis — a slow build-up of fat, cholesterol and calcium (plaque) inside the artery walls. As the arteries narrow, the leg muscles and feet do not get enough blood, especially during walking.

PAD is not just a leg problem. The same process that blocks leg arteries can also affect the heart and brain arteries. So PAD is a warning sign of higher risk of heart attack and stroke.

Why Is PAD Linked So Strongly With Diabetes?

Diabetes speeds up artery damage, and people with diabetes often have PAD in the smaller arteries below the knee. That is why PAD is commonly discussed alongside diabetes.

But diabetes is only one of several risk factors. The others are just as important — and some, like smoking, are even stronger.

What Causes PAD Without Diabetes?

1. Smoking and tobacco use Smoking is the single strongest risk factor for PAD. Cigarettes, bidis and chewing tobacco damage the inner lining of arteries and make blood more likely to clot. Smokers can develop PAD many years earlier than non-smokers.

2. High blood pressure Long-term high BP strains and damages artery walls, making it easier for plaque to build up.

3. High cholesterol High LDL (“bad”) cholesterol and triglycerides feed the plaque that narrows the arteries.

4. Age The risk of PAD rises sharply after the age of 50, and even more after 65.

5. Kidney disease Chronic kidney disease speeds up hardening and calcification of arteries.

6. Family history and existing heart disease If close family members had PAD, heart attack or stroke at a young age — or if you already have heart disease or have had a stroke — your risk is higher.

7. Obesity and an inactive lifestyle Extra weight and lack of exercise worsen BP, cholesterol and overall artery health.

Less Common Causes in People Without Diabetes

Not every leg artery blockage is due to plaque. Especially in younger people, doctors also look for:

• Buerger’s disease (thromboangiitis obliterans): Inflammation and clotting in small and medium arteries of the legs and arms, seen almost only in young tobacco users. It can cause toe ulcers and gangrene.
• Blood clots (embolism): A clot from the heart, for example due to an irregular heartbeat, can suddenly block a leg artery.
• Popliteal artery entrapment: A muscle or tendon behind the knee compresses the artery, usually in young, active people.
• Inflammation of blood vessels (vasculitis) and other rare artery conditions.

Key takeaway: If you smoke, have high BP or high cholesterol, or are over 50, you can develop PAD even with normal sugar levels.

Signs of PAD Without Diabetes

The symptoms of PAD are the same whether or not you have diabetes. Many people have no symptoms in the early stage. Watch for:

• Cramping, aching or tiredness in the calf, thigh or hip while walking that eases within a few minutes of rest (claudication)
• Being able to walk a shorter distance than before without stopping
• Cold feet, especially one foot colder than the other
• Numbness or weakness in the legs
• Shiny skin, hair loss on the legs, slow-growing toenails
• Weak or absent pulses in the feet
• Sores on toes or feet that heal slowly or not at all
• Pain in the toes or foot at night, eased by hanging the leg down from the bed — a sign of severe PAD

People often blame these symptoms on age, arthritis or “weakness”. If walking regularly brings on leg pain that settles with rest, get your circulation checked.

How Is PAD Diagnosed?

• Pulse check of the legs and feet
• Ankle-brachial index (ABI): A simple, painless test that compares BP at the ankle and the arm. It is especially reliable in people without diabetes, because their arteries are less likely to be falsely stiff from calcium.
• Arterial Doppler ultrasound: Shows exactly where the arteries are narrowed or blocked, and how severe it is.
• CT angiography: Gives a detailed map of the leg arteries to plan treatment.
• Blood tests: Cholesterol, sugar and kidney function to check overall risk.

Treatment for PAD Without Diabetes

1. Lifestyle changes

• Stop smoking and all tobacco — the most important step.
• Walk regularly. A structured walking programme can help the legs build new small blood vessels and improve walking distance.
• Eat a heart-healthy diet and keep a healthy weight.

2. Medicines Your doctor may prescribe medicines to thin the blood, lower cholesterol and control BP. These reduce the risk of heart attack and stroke as well as protecting the legs.

3. Opening the blocked artery If symptoms limit daily life, or there is rest pain, a non-healing wound or gangrene, the blocked artery may need to be opened.

How Interventional Radiology Treats PAD

An Interventional Radiologist can open blocked leg arteries from inside, without a large surgical cut:

1. A small puncture is made in the groin under local anaesthesia.
2. A thin wire and catheter are guided to the blockage using live X-ray.
3. A tiny balloon is inflated to open the narrowed artery (angioplasty).
4. A stent may be placed to keep the artery open.
5. Blood flow to the leg improves, often reducing pain and helping wounds heal.

Most patients go home within a day and return to routine activities quickly. Some long or complex blockages may need bypass surgery, which your care team will discuss.

How to Lower Your Risk of PAD Without Diabetes

• Quit smoking and all forms of tobacco — it is never too late.
• Check your BP regularly and keep it under control.
• Get your cholesterol tested, especially after 40.
• Walk at least 30 minutes on most days.
• Eat more vegetables, fruits, whole grains and less fried and salty food.
• Keep a healthy weight and limit alcohol.
• If you are over 50 and smoke or have high BP or cholesterol, ask your doctor about an ABI test.

Red Flags: See a Doctor Urgently

• Sudden cold, pale, painful or numb leg or foot — this is an emergency
• Black or dark blue toes
• A foot or toe wound not healing in 2 weeks
• Pain in the foot at rest or at night
• Walking distance shrinking quickly

What is Peripheral Artery Disease (PAD)?

Peripheral artery disease occurs when arteries that supply blood to the limbs become clogged with fatty deposits, leading to restricted blood flow. PAD is most commonly caused by atherosclerosis and often affects the legs, causing symptoms like leg pain during walking (claudication), numbness, and even ulcers in severe cases.

Signs and Symptoms of PAD

Early detection of PAD is crucial for effective treatment. Common signs include:

• Leg pain or cramping during exercise.
• Numbness or weakness in the legs.
• Slow-healing wounds on the feet or legs.
• Coldness in one leg or foot compared to the other.

If you experience these symptoms, consulting a healthcare professional is essential to prevent complications.

Top Treatments for Peripheral Artery Disease (PAD)

1. Lifestyle Changes: The First Step to Managing PAD

Adopting healthier habits can significantly improve your symptoms. Key lifestyle changes include:

• Quit Smoking: Smoking worsens artery blockages and must be stopped immediately.
• Exercise Regularly: Walking programs tailored to your ability can enhance circulation.
• Adopt a Heart-Healthy Diet: A diet rich in fruits, vegetables, whole grains, and lean protein can prevent further arterial damage.

2. Medications for PAD Management

Medical therapy plays a pivotal role in controlling symptoms and preventing disease progression. Commonly prescribed medications include:

• Antiplatelet Drugs: These reduce blood clotting and improve blood flow.
• Cholesterol-Lowering Drugs: Statins help prevent plaque buildup.
• Blood Pressure Medications: Controlling hypertension eases pressure on the arteries.

3. Minimally Invasive Procedures: Angioplasty and Stenting

For individuals with moderate to severe PAD, angioplasty may be recommended. This procedure involves inserting a balloon into the narrowed artery to widen it. Stents are sometimes placed to keep the artery open, ensuring improved blood flow.

4. Surgical Bypass for Severe Cases

In cases where blockages are extensive, bypass surgery may be necessary. This procedure involves creating a detour around the blocked artery using a graft, allowing blood to flow to the affected limb.

5. Thrombolytic Therapy

If blood clots are causing the blockage, thrombolytic therapy involves injecting clot-dissolving medications directly into the artery. This approach is effective in preventing further complications.

6. Advanced Treatments: Stem Cell Therapy and Gene Therapy

Emerging therapies like stem cell and gene therapy are showing promise in regenerating blood vessels and improving circulation in PAD patients. These treatments are currently under research but could revolutionize PAD management in the future.
