Your feet may not be the first place you think of for “heart health,” but they can reveal much about your cardiovascular system. Pain, numbness, or swelling may indicate serious heart problems or clogged arteries. Peripheral artery disease (PAD) and coronary artery disease (CAD) are forms of atherosclerosis that can manifest in the feet due to restricted blood flow.

Understanding PAD
PAD occurs when plaque buildup clogs arteries, causing discomfort and reduced mobility, often in the legs and feet. According to the Cleveland Clinic, PAD can cause pain, cramping, and, in severe cases, limb loss. Symptoms like difficulty standing or frequent leg cramps should prompt medical screening.

Testing for Clogged Arteries
Early detection of PAD helps prevent complications. Doctors may check pulses in your feet or perform an ankle-brachial index (ABI) test. This compares blood pressure in the ankle and arm to detect blockages. Swelling in feet or ankles, especially with a family history of heart disease, warrants immediate attention.

Impact of Poor Circulation
Poor circulation limits oxygen and nutrient delivery to tissues, causing pain, numbness, tingling, and slow wound healing. Plaque buildup further restricts blood flow. Weak heart function can cause swelling (peripheral edema).

Diabetes and Foot Health
For diabetics, nerve damage from high blood sugar worsens foot pain and numbness, making circulation care even more crucial. Managing blood sugar can help prevent complications.

Prevention
To prevent PAD and CAD, adopt a healthy lifestyle. Exercise regularly, eat a balanced diet low in saturated and trans fats, avoid smoking, and manage blood pressure, cholesterol, and blood sugar.

Heart–Foot Connection
A healthy heart supports healthy feet. Staying active and eating well reduces strain on both.

Conclusion
Listen to your body. Foot pain, numbness, and swelling can signal serious cardiovascular issues. Early detection and treatment protect both heart and overall health.
