Swollen Legs: What's Causing Your Edema?
Published: Sep 13, 2024
Edema, or swelling caused by fluid buildup, can affect various parts of the body. Understanding the causes and symptoms of leg edema can help you get proper treatment.
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.
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.
