Your feet might not be the first thing that comes to mind when you think of heart health, but they can offer critical insights into your cardiovascular system. Symptoms like pain, numbness, or swelling may indicate serious heart issues or clogged arteries. Conditions such as peripheral artery disease (PAD) and coronary artery disease (CAD) can manifest in your feet, signaling restricted blood flow due to plaque buildup.

PAD occurs when plaque blocks arteries, causing discomfort and mobility issues, often in the legs and feet. As the Cleveland Clinic notes, symptoms include leg and foot pain, cramping, and in severe cases, limb loss. Early detection, through tests like the ankle-brachial index (ABI), can prevent serious complications.

Poor circulation from clogged arteries or heart failure can cause pain, numbness, and slow wound healing in your feet. For diabetics, foot pain and numbness can worsen due to nerve damage. Swollen legs and feet can also be a sign of peripheral edema, linked to heart problems.

Preventing PAD and CAD involves regular exercise, a balanced diet, and avoiding smoking. The U.S. Department of Health and Human Services recommends 150 minutes of moderate exercise weekly. Monitoring blood sugar, blood pressure, and cholesterol levels is essential.

In short, your feet can signal heart problems, so listen to your body. Early detection and lifestyle changes can protect your heart and improve overall health.
