What Is the Relationship Between Diabetic Foot and Peripheral Artery Disease (PAD)? - Dr Uday Ravi
Recognize the Signs. Protect Every Step-Dr Uday Ravi
Diabetes can affect both nerve function and blood circulation in the feet. One condition that people with diabetes should know about is Peripheral Artery Disease (PAD), which occurs when narrowed arteries reduce blood flow, commonly to the legs and feet.
Understanding the connection between diabetic foot problems and PAD can help people recognise warning signs and seek medical care promptly.
What Is Peripheral Artery Disease (PAD)?
Peripheral Artery Disease is a circulation condition in which arteries that carry blood to the legs and feet become narrowed, often because of atherosclerosis, a buildup of plaque inside the arteries.
People with diabetes have an increased risk of developing PAD. Other risk factors include smoking, high blood pressure, high cholesterol, and increasing age.
How Are Diabetic Foot Problems and PAD Connected?
PAD reduces the amount of oxygen-rich blood reaching the feet. Diabetes can also damage the nerves, causing reduced sensation or numbness.
When these conditions occur together, a person may not notice a foot injury, and the reduced blood supply can make healing more difficult.
The connection can lead to:
✓ Slow-healing wounds: Cuts, blisters, and ulcers may take longer to heal when blood flow is reduced.
✓ Increased risk of infection: Open wounds can become infected and may require prompt treatment.
✓ Reduced sensation: Diabetic nerve damage can make injuries harder to notice.
✓ Greater risk of serious complications: Severe circulation problems and untreated wounds can lead to tissue damage.
What Are the Warning Signs of PAD in the Legs and Feet?
PAD does not cause noticeable symptoms in everyone. Possible signs include:
✓ Leg discomfort or cramping while walking that improves with rest
✓ One foot feeling colder than the other
✓ Changes in the colour of the feet or toes
✓ Slow-healing sores on the feet or toes
✓ Reduced hair growth on the legs or feet
✓ Weak foot pulses, identified during a clinical examination
Some people with diabetes may not experience typical leg pain because nerve damage can affect sensation.
Important: A new foot wound, particularly in someone with diabetes, should be assessed promptly by a healthcare professional. Sudden severe foot pain, a suddenly cold or pale foot, or blackened tissue requires urgent medical attention.
How Is PAD Diagnosed?
A healthcare professional may assess circulation by examining the feet and checking pulses. Depending on the findings, tests may include:
Ankle-Brachial Index (ABI): Compares blood pressure at the ankle and arm.
Toe pressure testing: Measures blood pressure in the toes and may be useful when diabetes makes ABI results difficult to interpret.
Doppler ultrasound: Evaluates blood flow through the arteries.
The appropriate tests depend on the person's symptoms and medical history.
How Can People With Diabetes Protect Their Feet?
1. Check Your Feet Daily
Look for cuts, blisters, swelling, redness, skin-colour changes, or wounds. Check the soles and between the toes using a mirror if needed.
2. Choose Suitable Footwear
Wear comfortable, well-fitting shoes that protect your feet from pressure and injury. Check inside your shoes before wearing them and avoid walking barefoot.
3. Manage Diabetes and Other Risk Factors
Follow your healthcare professional's advice for blood glucose, blood pressure, and cholesterol management. If you smoke, ask for help with quitting.
4. Attend Regular Foot Check-Ups
Routine examinations can help identify changes in sensation, circulation, and skin health. People with previous ulcers, PAD, or nerve damage may need more frequent assessments.
5. Never Ignore a Wound
Seek prompt medical advice for a foot wound that is not healing or shows signs of infection. Do not attempt to cut away corns or calluses yourself.
Can PAD Be Treated?
Yes. Treatment depends on the severity of the condition and may include managing risk factors, prescribed medication, a supervised exercise programme when appropriate, and procedures to improve blood flow in selected cases.
If a person has diabetes and a foot ulcer, clinicians may assess both the wound and the circulation to help determine the appropriate care.
Conclusion
Peripheral Artery Disease can reduce blood flow to the feet, while diabetes may also affect sensation and wound healing. Recognising possible symptoms, checking your feet every day, managing cardiovascular risk factors, and seeking timely medical assessment can help reduce the risk of serious complications.
