When you think about heart health or clogged arteries, your mind probably goes straight to chest pain, shortness of breath, or high blood pressure.
But your feet – the often-overlooked messengers of your circulatory system – can actually be the first to show signs of trouble. They can reveal early warnings of serious conditions like blocked arteries and heart disease long before other symptoms appear.
Your feet may be telling you much more about your health than you realize. Frequently ignored, they can signal major cardiovascular issues such as peripheral artery disease (PAD) and coronary artery disease (CAD). Both are forms of atherosclerosis, a condition where fatty plaque builds up in the arteries and restricts blood flow.
What is PAD?
Peripheral artery disease occurs when narrowed arteries limit blood flow to your limbs, especially the legs and feet. This happens when plaque, made up of fat, cholesterol, and other substances, collects inside the arteries, making them stiff and narrow.
How PAD shows up in your feet
According to WebMD, your feet often show the first symptoms of PAD, including:
- Cold feet: Reduced blood circulation prevents warm blood from reaching your extremities, leading to cold feet even in warm conditions.
- Slow-healing wounds: Small cuts or blisters may take much longer to heal due to poor blood supply.
- Pain while walking: Aching or cramping in the legs or feet during activity that eases when resting.
- Discoloration: The skin on the feet may look pale, bluish, or purplish because of limited circulation.
Ignoring PAD can cause serious problems like critical limb ischemia, infections, gangrene, and even amputation if untreated. It also often points to plaque buildup in other arteries, including those supplying blood to the heart and brain.
What is CAD?
Coronary artery disease affects the arteries that carry blood to the heart. When these arteries become clogged with plaque, the heart gets less oxygen, raising the risk of a heart attack.
Interestingly, CAD can also show signs in the feet:
- Swelling (edema): Poor heart function causes fluid buildup, leading to swelling in the feet and ankles.
- Tingling or numbness: Limited blood flow can cause tingling or a pins-and-needles feeling in the toes.
- Skin changes: The skin may appear shiny or tight due to fluid retention and circulation issues.
- Foot pain at rest: Unlike PAD, pain related to CAD can continue even while resting, especially at night.
- Brittle toenails: Inadequate blood flow can weaken nails, making them thick and brittle.
The American Heart Association (AHA) warns that CAD is becoming more common even in children and young adults. They emphasize that early prevention through healthy eating, maintaining a healthy weight, and staying active can slow or even improve the progression of the disease. They also note that if someone has PAD, there’s a strong likelihood they also have CAD.
How to protect yourself from PAD and CAD
The best approach to avoid complications from these conditions is prevention. You can lower your risk and protect both your heart and feet by following these steps:
- Stay active: Regular exercise boosts circulation and prevents plaque buildup. The CDC suggests at least 30 minutes of moderate physical activity, such as brisk walking or swimming, each day.
- Eat a heart-healthy diet: Focus on fruits, vegetables, whole grains, and lean proteins while limiting processed foods and unhealthy fats.
- Quit smoking: Tobacco constricts blood vessels and worsens circulation, significantly increasing your risk of both PAD and CAD.
- Manage stress: Chronic stress can raise blood pressure and contribute to heart disease. Relaxation practices like meditation or deep breathing can help.
- Control blood sugar: If you have diabetes, keeping blood glucose in check is crucial for preventing damage to your feet and circulatory system.
- Schedule regular check-ups: If you have high blood pressure, diabetes, or a family history of heart problems, seeing your doctor regularly can help catch issues early.
Your feet can offer important insights into your cardiovascular health. Paying attention to changes like persistent coldness, swelling, or cramping could help detect heart and circulation problems before they become serious.
