What Causes Leg Swelling?

Swelling in the legs, also known as edema, can occur for various reasons. Common causes include:

  • Chronic Venous Insufficiency: Impaired blood return to the heart
  • Varicose Veins: Enlarged veins blocking blood flow
  • Lymphedema: Improper lymphatic fluid drainage
  • Deep Vein Thrombosis: Blood clots causing sudden swelling
  • Heart/Kidney Conditions: Fluid retention in lower extremities

How Is Leg Swelling Treated?

Treatment for swelling targets the specific cause while focusing on three key goals: improving blood flow, easing discomfort, and resolving the underlying problem.

Some recommended treatments may include:

  • Lifestyle modifications to improve circulation and reduce fluid retention
  • Compression therapy to support vein function and alleviate swelling
  • Treatment of underlying vein conditions, such as CVI or varicose veins
