Do Compression Socks Help with Edema?
Jul 3, 2025

If you’ve ever experienced swollen legs, ankles, or feet, especially after a long day, travel, or standing for hours, you might be dealing with edema, a condition that causes fluid buildup in the body’s tissues.

What Is Edema?

Edema occurs when excess fluid collects in the tissues, often in the lower legs, ankles, and feet. It can be mild and occasional, or persistent and linked to health issues such as:

  • Poor circulation
  • Chronic venous insufficiency
  • Prolonged sitting or standing
  • Pregnancy
  • Post-surgical recovery
  • Heart, kidney, or liver conditions

If left unmanaged, edema can cause discomfort, heaviness, and long-term tissue strain.

How Compression Socks Can Help

Compression socks apply graduated pressure to the legs, meaning they’re tightest at the ankle and gradually loosen toward the calf or thigh. This pressure helps:

  • Reduce fluid buildup by encouraging blood and lymph flow back toward the heart
  • Prevent pooling in the lower extremities
  • Relieve swelling, heaviness, and fatigue in the legs
  • Support vein health, reducing risk of varicose veins and related complications

By gently squeezing the legs, compression socks help your body move fluids more efficiently, providing noticeable relief from swelling and discomfort.

Choosing the Right Compression Level

Compression socks come in different pressure levels, typically measured in mmHg (millimeters of mercury). The right level for managing edema depends on your symptoms and whether it’s a medical or lifestyle concern:

  • Mild (8–15 mmHg)
  • Moderate (15–20 mmHg)
  • Firm (20–30 mmHg)
  • Extra Firm (30–40 mmHg

Some levels of pressure require a prescription from a licensed medical professional. Please reach out to your local healthcare provider or certified fitter for more information.
