Varicose Veins and Edema: The Connection Between Vein Problems and Leg Swelling

Medically reviewed by Thomas Alosco, MD, DABS, RPVI, RVT, DABVLM, on February 20, 2025

If you’ve noticed swelling in your legs and bulging veins just under your skin, you might wonder if these two issues are connected. Varicose veins and edema (leg swelling) often go hand in hand, and both can be signs of vein disease—a condition that affects millions of people worldwide. According to the National Library of Health (NIH), 56 percent of men and 60 percent of women in the Western world experience the discomfort of varicose veins.

Did you know:

• According to the AHA Journal Circulation, approximately 23 percent of adults in the United States have varicose veins.
• Per the American Family Physician Journal (AFP) Peripheral Edema: Evaluation and Management in Primary Care, about 20 percent of adults over age 50 experience leg swelling, known as edema.
• A significant number of these cases are linked to venous insufficiency, also known as vein disease, where veins struggle to send blood back to the heart, leading to fluid buildup in the legs. Per AFP: “For patients with chronic bilateral lower-extremity edema, duplex ultrasonography with reflux can help diagnose chronic venous insufficiency.”

Understanding the connection between chronic venous insufficiency, varicose veins, and edema is crucial for maintaining vascular health. Recognizing the signs and seeking appropriate treatment can prevent potential complications and improve your quality of life.

For this article, we spoke to Center for Vein Restoration (CVR) vein doctor Thomas Alosco, MD, DABS, RPVI, RVT, DABVLM. Dr. Alosco is a board-certified physician specializing in general surgery and venous and lymphatic medicine and the lead physician at CVR’s vein clinic in Waterbury, Connecticut.

What Are Varicose Veins?

Varicose veins are enlarged, twisted veins that commonly appear on the legs. They develop when the tiny valves inside the veins stop working properly, causing blood to pool rather than flow efficiently back to the heart. This condition is known as venous insufficiency, the underlying cause of most vein problems.

What Causes Varicose Veins?

Several factors can increase your risk of developing varicose veins, including:

• Genetics – If your parents had varicose veins, you are more likely to develop them.
• Age – Veins lose elasticity as you age, making them more prone to damage.
• Prolonged sitting or standing – Jobs that require long hours on your feet or sitting at a desk can contribute to vein problems.
• Pregnancy – Increased blood volume and hormonal changes can weaken vein walls.
• Obesity – Excess weight puts added pressure on your veins.
• Lack of exercise – Physical activity promotes healthy circulation and reduces vein-related risks.

What Is Edema?

Edema refers to swelling caused by fluid buildup in the body’s tissues. It commonly affects the legs, ankles, and feet and can be linked to vein disease, heart conditions, kidney problems, and other underlying health issues.

What Causes Edema?

The most common causes of leg swelling include:

• Venous insufficiency – When blood pools in the veins instead of flowing properly, fluid leaks into surrounding tissues, leading to swelling.
• Lymphedema – A condition where the lymphatic system cannot drain fluid effectively, causing chronic swelling.
• Heart disease – Congestive heart failure can cause fluid retention in the legs.
• Kidney disease – The kidneys help regulate fluid balance; swelling can occur when they don’t function properly.
• Injury or infection – Trauma to the legs, inflammation, or infections can lead to swelling.

The Connection Between Varicose Veins and Edema

Varicose veins and edema often appear together because both result from poor circulation in the legs. When blood doesn't flow efficiently due to vein damage, it increases pressure within the veins, leading to fluid leakage and inflammation. Over time, chronic swelling can worsen vein problems, making it harder for your body to heal and leading to further complications.

Complications of Untreated Varicose Veins and Edema

Ignoring varicose veins and edema can lead to serious health issues, including:

• Skin changes – Persistent swelling and poor circulation can cause skin discoloration, itching, and thickening.
• Venous ulcers – Open sores may develop on the legs due to prolonged poor circulation.
• Blood clots – A condition called deep vein thrombosis (DVT) can occur if blood pools and forms a clot in a deep vein, potentially leading to life-threatening complications.
• Infections – Swollen legs can be more prone to cellulitis, a painful skin infection.

The good news is that modern vein treatment options are minimally invasive, highly effective, and require little downtime. These include:

• Lifestyle changes – Regular exercise, weight management, and avoiding prolonged sitting or standing can improve circulation.
• Compression therapy – Wearing compression stockings can help reduce swelling and support proper blood flow.
• Sclerotherapy: A minimally invasive procedure in which a medicine is injected into varicose veins to close them off.
• Endovenous laser ablation (EVLA) or radiofrequency ablation (RFA) – Heat-based treatments that seal off damaged veins, rerouting blood flow to healthier veins.
• Venaseal™ – A medical adhesive that closes off diseased veins permanently.
