Common Causes of Leg Swelling

There are several reasons why your legs might swell. Heart failure is a frequent culprit, causing fluid to build up when the heart can't pump effectively. Chronic venous disease, where blood doesn't flow properly through leg veins, is another common cause. Less often, kidney or liver problems can lead to edema. Sometimes, medications like certain blood pressure pills can also cause swelling.

When to Worry About Leg Edema

While some leg swelling is harmless, certain symptoms warrant immediate medical attention. Sudden swelling in one leg, especially with pain or redness, could indicate a blood clot. This requires prompt evaluation. Bilateral leg swelling with shortness of breath might signal heart failure. If you experience these symptoms, seek medical care right away.
Edema refers to swelling caused by fluid buildup, commonly affecting the legs. It can be caused by heart failure, chronic venous disease, kidney or liver problems, and certain medications.

Diagnosing the Cause of Edema

To determine why your legs are swollen, your doctor will likely start with a physical exam and medical history. They may order blood tests to check your kidney and liver function. An ultrasound can look for blood clots or vein problems. In some cases, your doctor might recommend an echocardiogram to evaluate your heart function.
