The body works in a delicate balance, and swollen feet can be an important signal when something is off. This swelling, called edema, happens when fluid leaks from blood vessels and collects in tissues, often in the feet due to gravity—especially after long sitting, standing, or heat exposure.
Lifestyle factors like high salt intake, inactivity, and hot weather can worsen it, while injuries may cause temporary, localized swelling. However, persistent or unexplained swelling can point to deeper issues involving the heart, kidneys, or liver.
Warning signs include swelling in one foot, pain, redness, warmth, or symptoms like chest pain or shortness of breath—these need urgent medical attention.
For most people, simple steps help: elevate your feet, move regularly, wear compression socks, reduce salt, and stay hydrated.
Swollen feet aren’t just discomfort—they’re the body’s way of asking for attention.
