Swollen feet may seem like a minor nuisance, but they’re often your body’s early alarm system. Fluid pooling in the lower legs can come from simple causes like heat, long hours sitting or standing, salty food, or pregnancy. But when swelling is persistent, painful, or affects just one leg, it may signal blood clots, heart failure, kidney problems, or liver disease that should never be ignored.
You can support your circulation at home by elevating your legs, staying hydrated, wearing compression socks, and cutting back on sodium while adding potassium-rich foods. Gentle movement, comfortable footwear, and avoiding long periods of inactivity can also ease fluid buildup. Still, swelling that doesn’t improve, appears suddenly, is accompanied by redness, shortness of breath, chest pain, or affects only one leg demands urgent medical attention. Listening to your feet now may protect your life later.
