When thinking about heart health, your feet are probably not the first thing that comes to mind.
Yet, because they are the farthest part of your body from your heart, they can reveal early clues about circulation problems and even potential heart disease. Here are several important signs to watch for.
1. Changes in Hair Growth
The hair on your toes can say a lot about circulation. If you’ve always had hairier toes but suddenly notice thinning or complete loss, it could be a warning sign.
Healthy blood flow keeps hair growing, while reduced circulation in small vessels may point to vascular disease, atherosclerosis, or even a heart that isn’t pumping as well as before. In short, hairless toes may be more than a cosmetic issue—they could be a signal of cardiovascular trouble.
2. Swelling in the Feet and Ankles
Many people ignore swelling in their lower legs, chalking it up to age or long days on their feet. But persistent swelling (edema) is often tied to poor circulation, fluid buildup, or even serious heart conditions. If pressing on your foot leaves a dent that lingers, or if your socks leave deep marks, that’s not normal.
Possible causes include congestive heart failure, vein blockages, kidney disease, liver problems, or deep vein thrombosis. Chronic venous insufficiency can also cause severe swelling by day’s end. Simple steps like elevating your legs, wearing compression socks, or gentle chair exercises may help, but ongoing swelling should never be dismissed—it requires medical attention.
