Key Takeaways
- PAD narrows the arteries to the legs; its hallmark symptom is calf, thigh or buttock cramping on walking that eases with rest
- Many people have no symptoms, so diabetes, smoking, high cholesterol, high blood pressure and age over 50 are reasons to be screened
- A sudden cold, pale or painful leg, or a spreading foot infection, is an emergency
- A simple ankle-brachial index test, with Doppler ultrasound, can diagnose PAD without needles or radiation
- At DCDC, a cardiology consultation starts from AED 250, Doppler from AED 500, and many tests can be completed in one visit
Peripheral artery disease symptoms such as leg cramping when walking, cold feet and sores that will not heal are easy to dismiss, yet they can signal narrowed arteries and a raised risk of heart attack and stroke. A cardiology consultation at Doctors Clinic Diagnostic Center (DCDC) in Dubai Healthcare City, from AED 250, can find out whether poor leg circulation is behind your symptoms.
Globally, more than 200 million people live with PAD, and the condition is widely underdiagnosed because the symptoms creep in slowly and are blamed on age, arthritis or a bad back. In the UAE, high rates of diabetes, obesity, inactivity and smoking make the risk factors common. This guide covers the PAD warning signs, a severity scale, the red flags that need urgent care, who should be screened, how the ankle-brachial index test and Doppler ultrasound work, and what to expect at DCDC. It is for general information and does not replace medical advice.
What Is Peripheral Artery Disease?
Peripheral artery disease is a circulatory condition in which the arteries that carry blood to your limbs, most often your legs, become narrowed or blocked. The usual cause is atherosclerosis: a gradual build-up of cholesterol, calcium, inflammatory cells and scar tissue (plaque) inside the artery wall. As the plaque grows, the channel inside the artery shrinks and less oxygen-rich blood reaches the muscles of the calves, thighs and buttocks.
At rest, a partly narrowed artery may still deliver enough blood, so you feel nothing. When you walk or climb stairs, your leg muscles demand far more oxygen than the narrowed vessel can supply. The result is the cramping, tiring pain that doctors call claudication. In more advanced disease, blood flow is too low even at rest, and the skin and tissue of the foot begin to suffer.
PAD matters beyond the legs. Atherosclerosis is a body-wide process, so someone with PAD very often has plaque in the coronary arteries of the heart and in the carotid arteries of the neck as well. Guidelines treat a PAD diagnosis as a marker of high cardiovascular risk. You can read more about the neck arteries in our guide to Carotid Doppler for stroke risk and about heart warning signs in heart disease symptoms in Dubai.
Not every leg circulation problem is PAD. Leg pain and swelling can also come from venous disease, nerve compression, arthritis or muscle strain. Working out which one you have is the main reason a proper examination and a simple blood-flow test are so valuable.
Warning Signs and Symptoms of PAD
Roughly half of people with PAD have no obvious leg symptoms, and many others dismiss their discomfort as normal ageing or a stiff back. The signs below are the ones that most often point to reduced leg circulation. Having one of them does not confirm PAD, but several together, especially alongside risk factors, justify a check.
Intermittent Claudication (Leg Pain When Walking)
Claudication is the classic PAD symptom. It is a cramping, aching, heavy or tiring sensation in the calf, thigh or buttock that appears after a predictable amount of walking and settles within a few minutes of rest. Pain in the calf suggests narrowing in the thigh arteries, while buttock and thigh pain suggests disease higher up, near the pelvis.
Typical claudication causes follow a pattern: the same distance brings on the same pain, walking uphill or faster makes it worse, and standing still for a minute or two relieves it. This is different from the pain of spinal stenosis, which often eases only when you sit or bend forward, and from pain that is there from the first step. Many people unconsciously shorten their walks or stop to look in shop windows, so the problem goes unnoticed for years.
Numbness or Weakness in Legs
Reduced blood flow can leave the legs feeling weak, heavy or tingling, particularly during activity. Some people describe the feeling that a leg will give way. Because diabetic nerve damage causes similar numbness, the two conditions are easily confused and often coexist. If you have diabetes, new numbness deserves a circulation check as well as a nerve assessment.
Cold Feet or Legs
One foot or lower leg that is noticeably colder than the other, or a foot that stays cold in a warm room, can signal poor arterial supply. This is different from generally cold hands and feet in an air-conditioned office, which usually affects both sides equally. Look for a one-sided temperature difference, together with pale or bluish skin.
Slow-Healing Wounds on Feet or Legs
Sores, blisters, cuts or ulcers on the toes, heels or shins that fail to heal within two to four weeks are a significant warning sign. Healing needs oxygen and nutrients, and an inadequate blood supply stalls the process. Wounds may be painless in people with diabetes because of nerve damage, which is why daily foot inspection matters. Our guides to diabetic foot care and diabetes complication warning signs explain what to look for.
Skin Color Changes
Skin on the affected leg may look pale, shiny and thin, or take on a bluish or dusky tone. A classic sign of severe disease is dependency rubor: the foot turns deep red when hanging down and goes pale when raised. Any dark, black or blue-grey patch on a toe or heel needs urgent attention because it can indicate tissue death.
Hair Loss on Legs
Hair thinning or loss on the shins, feet and toes, slower toenail growth, and brittle or thickened nails all reflect long-standing poor blood supply to the skin. On its own, hair loss is a soft sign, since it also occurs with age. Combined with cold skin, pain on walking or weak foot pulses, it adds weight to the suspicion of PAD.
PAD Symptom Severity Scale
Doctors often grade PAD by how much it limits daily life and how threatened the limb is. The table below is a simplified guide based on the widely used Fontaine and Rutherford classifications. It is a self-orientation tool, not a diagnosis.
| Stage | What You Notice | Typical Walking Impact | Suggested Action |
|---|---|---|---|
| Mild | Occasional calf tightness or tiredness after longer walks; sometimes no symptoms at all | Can walk several blocks before discomfort | Book a vascular risk check and an ankle-brachial index test |
| Moderate | Predictable cramping in calf, thigh or buttock that forces you to stop and rest | Limited to a short distance, often 100 to 200 metres | Arrange assessment within a few weeks; begin risk-factor control and a walking plan |
| Severe | Pain at rest, especially at night in the foot or toes, relieved by hanging the leg down | Pain even when not walking; disturbed sleep | See a doctor promptly, ideally within days |
| Critical | Non-healing ulcers, black or dying skin, infection, persistent cold painful foot | Limb is at risk of amputation without treatment | Seek urgent medical care the same day |
Progression is not inevitable. With treatment, many people stay in the mild or moderate stages for years, but severity can change, so tracking your walking distance and checking your feet regularly is worthwhile.
When to See a Doctor Urgently
Most PAD develops slowly, but a sudden blockage in a leg artery (acute limb ischaemia) is a medical emergency. Go to the nearest emergency department, do not wait for an appointment, if you notice any of the following:
- A leg or foot that suddenly becomes cold, pale, blue or mottled
- Sudden severe leg pain that does not ease with rest
- Sudden numbness, tingling or inability to move the foot or toes
- A leg without a pulse that was previously normal
- A foot wound with spreading redness, swelling, pus, fever or a bad smell
- Black, dry or blue-grey patches of skin on toes or heels
- Severe foot pain at night that is only eased by dangling the leg over the bed
Also arrange a prompt (non-emergency) appointment if you have leg pain on walking that is getting worse, a sore that has not healed in two weeks, or any leg symptoms together with chest pain, breathlessness or sudden weakness on one side, since these suggest the wider circulation may be involved.
Who Is at Risk?
PAD is strongly linked to modifiable lifestyle and medical factors. Use this checklist to see how many apply to you. The more boxes you tick, the stronger the case for screening, even if you have no symptoms.
- Diabetes (type 1 or type 2): the single strongest driver of severe PAD and amputation risk
- Smoking, including shisha and vaping exposure: current and former smokers carry the highest risk
- High cholesterol, particularly raised LDL
- High blood pressure
- Age 50 or over, or age 65 and above regardless of risk factors
- Family history of PAD, heart attack or stroke
- Chronic kidney disease
- Known coronary artery disease or previous stroke
- Overweight or obesity
- Physical inactivity
Risk Factors Specific to Dubai and the UAE
Several local factors raise the burden. The UAE has one of the higher diabetes rates in the region, with estimates generally in the range of 16 to 18 percent of adults according to International Diabetes Federation data. Sedentary work patterns, car-dependent travel, hot summers that discourage outdoor walking, high rates of obesity and widespread shisha smoking all add to vascular risk. Gulf studies of patients with existing heart or brain-vessel disease have found that a notable share have silent PAD, and studies of UAE patients with type 2 diabetes have found abnormal ankle-brachial readings in a substantial minority. Our article on diabetes and heart disease risk looks at how these factors connect.
How PAD Is Diagnosed
Diagnosis starts with a conversation and examination: your walking history, risk factors, a check of leg pulses, skin temperature, colour and any wounds. Simple non-invasive tests then confirm and map the disease. Current AHA/ACC guidance recommends a resting ankle-brachial index as the first test for anyone with suspected PAD, with imaging used to plan treatment when needed.
Ankle-Brachial Index (ABI) Test
The ankle-brachial index test compares blood pressure at the ankle with blood pressure in the arm. A cuff is inflated on each arm and ankle while a small handheld Doppler probe detects the pulse. It takes about 15 to 20 minutes, is painless apart from the cuff squeeze, and needs no preparation.
- 1.00 to 1.40: normal
- 0.91 to 0.99: borderline
- 0.90 or below: PAD is present
- 0.40 to 0.69: moderate disease range
- Below 0.40: severe disease range
- Above 1.40: arteries may be stiff and calcified, so the reading is unreliable; a toe-brachial index or Doppler study is used instead
The above-1.40 category is especially relevant in Dubai, because long-standing diabetes and kidney disease stiffen arteries and can hide PAD behind a falsely normal number. An exercise ABI, measured after treadmill walking, can also uncover disease that looks normal at rest.
Doppler Ultrasound
Duplex Doppler ultrasound uses sound waves to produce live images of the arteries and to measure the speed and pattern of blood flow. It shows where an artery is narrowed or blocked, how severe the narrowing is and whether the vessel wall is calcified. There is no radiation and no needle, and the scan usually takes 30 to 45 minutes. At DCDC the on-site Doppler ultrasound starts from AED 500. For a breakdown of fees, see Doppler ultrasound cost in Dubai.
CT Angiography
CT angiography uses a quick scan and contrast dye to create detailed three-dimensional pictures of the arteries from the abdomen to the feet. It is not needed for everyone. Doctors reserve it for advanced cases, for people with severe symptoms, or when an endovascular procedure or bypass is being planned. CT angiogram is available at DCDC from AED 2,500. Kidney function is checked beforehand because the dye can affect the kidneys.
PAD vs Varicose Veins: Key Differences
Leg heaviness and discomfort are common to both PAD and vein problems, but the underlying plumbing is different. PAD is a problem of arteries delivering blood to the leg. Varicose veins and chronic venous insufficiency are problems of veins returning blood to the heart. Mixing them up can lead to wrong treatment, and compression stockings, helpful for vein disease, can be harmful in severe PAD.
| Feature | Peripheral Artery Disease | Varicose Veins / Venous Disease |
|---|---|---|
| Blood vessels involved | Arteries (blood going to the leg) | Veins (blood returning from the leg) |
| Typical pain | Cramping in calf, thigh or buttock on walking; relieved by rest | Aching, heaviness or throbbing that worsens with standing and eases when legs are raised |
| Appearance | Pale, shiny, cool skin; hair loss; sometimes dusky red foot | Visible twisted bulging veins; brownish skin staining near the ankle; swelling |
| Temperature | Cool or cold foot | Normal or warm leg |
| Swelling | Uncommon | Common, especially by evening |
| Pulses | Weak or absent foot pulses | Pulses normally present |
| Wounds | Painful ulcers on toes, heels or foot edges | Ulcers near the inner ankle, often shallow and wet |
| Elevating the leg | Often makes pain worse | Usually brings relief |
| Main test | ABI and arterial Doppler | Venous duplex Doppler |
It is possible to have both conditions together. If you are considering vein treatment, read our guide to varicose veins treatment in Dubai, and make sure your arteries have been assessed first.
Book a Cardiovascular Screening
Worried about leg circulation or have risk factors such as diabetes, smoking or high cholesterol? A cardiology consultation at Doctors Clinic Diagnostic Center in Dubai Healthcare City starts from AED 250 and includes a cardiovascular risk assessment. Doppler ultrasound can often be arranged during the same visit.
Treatment Options for PAD
The goals of treatment are to relieve symptoms, improve how far you can walk, protect your limbs and lower the chance of heart attack and stroke. Most people are managed without surgery. Treatment is tailored by your cardiologist or vascular team.
Lifestyle Changes
- Stop all tobacco, including shisha: this is the most effective single step to slow PAD
- Follow a Mediterranean-style diet rich in vegetables, legumes, fish, nuts and olive oil, and lower in processed food and sugary drinks
- Aim for a healthy weight
- Control blood sugar to the targets agreed with your doctor
- Inspect your feet daily, wear well-fitting shoes and never walk barefoot on hot ground
- Limit alcohol and manage stress and sleep
Medication
Guidelines recommend several medicines for symptomatic PAD. Antiplatelet therapy (aspirin or clopidogrel) lowers the risk of heart attack, stroke and limb events. Statins reduce LDL cholesterol and improve outcomes in PAD. Blood pressure medicines protect the arteries, and diabetes treatment is optimised to protect circulation. Some patients benefit from cilostazol to lengthen walking distance, and in selected people a low dose of rivaroxaban together with aspirin may be considered. Never start or stop these medicines without medical advice.
Exercise Therapy
Supervised exercise is among the most effective treatments for claudication and in trials improves walking distance by a clinically meaningful amount. A typical programme involves walking until moderate leg discomfort, resting until it settles, then repeating, for about 30 to 60 minutes, three times per week for at least 12 weeks. If a supervised class is unavailable, a structured home walking programme is a recognised alternative. In Dubai summer, malls and air-conditioned indoor tracks make a practical choice.
Endovascular Procedures
When symptoms severely limit life despite medicines and exercise, or when the limb is threatened, revascularisation may be advised. Options include balloon angioplasty, stenting, atherectomy and, for longer or more complex blockages, bypass surgery. Imaging such as Doppler and CT angiography guides which procedure is suitable. Decisions are individual and are made together with a vascular specialist.

Final Thoughts
Peripheral artery disease is common, serious and treatable, but only when it is found. Leg pain on walking, cold feet, slow-healing sores or skin changes are not just signs of getting older. If you have diabetes, smoke, or have high cholesterol or blood pressure, a simple ankle-brachial index test and Doppler ultrasound can give you answers in a single visit.
