Many people experience cold feet during chilly weather and assume it is harmless. However, persistent cold feet may indicate underlying health problems, most notably high cholesterol and peripheral artery disease, known as the “silent killer” due to its subtle symptoms.

Why Are Cold Feet a Concern?

Doctors warn that continuous cold feet, even with socks or in mild temperatures, may reflect poor circulation. Fat and cholesterol buildup in the arteries can narrow or block them, reducing blood flow to the legs and feet.

What Is Peripheral Artery Disease?

Peripheral artery disease occurs when arteries harden due to plaque buildup, limiting blood flow to extremities, especially legs and feet. Reduced oxygen and nutrient supply leads to tissue distress, and without early diagnosis, the condition can worsen. Over 200 million people worldwide are affected.

Key Symptoms to Watch

• Persistent cold feet

• Leg pain or cramps while walking or exercising

• Numbness or tingling in the feet

• Pain at rest or while lying down

• Slow-healing wounds or sores

• Skin color changes (pale, purple, or dark)

• Tingling or extreme cold sensation when touching the feet

In advanced cases, inadequate blood supply may damage tissues, particularly in the toes, with potential severe complications if untreated.

Causes and Risk Factors

The disease develops as arteries lose their elasticity due to fat and cholesterol accumulation, forming clots that increase the risk of complete blockage. Risk factors include:

• High cholesterol or triglycerides

• Smoking

• Diabetes

• High blood pressure

• Chronic kidney disease

• Aging

Prevention and Early Diagnosis Tips

• See a doctor immediately if cold feet persist with pain, numbness, or skin color changes

• Regularly check cholesterol, blood pressure, and blood sugar

• Exercise to improve circulation

• Maintain a healthy weight and balanced diet

• Stay hydrated and avoid smoking
