What Causes Swollen Legs?

Legs can swell for many reasons (called edema) and this symptom can sometimes indicate a health problem. Swollen legs can be a sign that the blood flow in your lower legs has become dysfunctional. If you have swollen legs, we recommend an assessment by a vein specialist like Dr. Dohner to determine the cause and appropriate treatment. 

What Causes Swollen Legs?

Leg swelling generally indicates that fluid has accumulated. Causes of this swelling can include:

  • Spending long periods of time on your feet or sitting in one position
  • Heart failure and lung diease
  • Liver disease
  • Kidney disease
  • Lymphedema (accumulation of fluid from the lymphatic system)
  • Injury or infection
  • Venous insufficiency

Venous insufficiency is a very common cause of swollen legs. This condition occurs when one-way valves in your deep leg veins stop working properly. As a result, blood starts to pool in the veins, causing them to bulge and weaken. 

What are Varicose Veins?

Varicose veins are a common condition, and are usually much more than just a cosmetic problem. They appear as bulging, twisted ropes under the skin, and they can look blue, red, or purple. This appearance indicates veins that have become stretched and damaged by pooling blood. 

Varicose veins can be a sign that you have more significant issues with the veins under the skin in your legs. This venous insufficiency can cause symptoms like swelling, aching, heaviness, cramps, restlessness, and pain. 

How are Swollen Legs and Varicose Veins Treated?

If you have swollen legs caused by varicose veins, Dr. Dohner will develop a customized treatment plan to improve them. This treatment plan will often include a combination of these methods:

Endovenous Laser Treatment (EVLT)

This treatment seals and stops the blood flow through damaged veins that feed your visible varicose veins. A thin fiber inserted into the vein delivers laser energy that damages the vein walls, causing them to collapse. 

Varithena® and Ultrasound-Guided Sclerotherapy

This method works especially well for hard-to-reach problem veins. Dr. Dohner uses ultrasound to precisely inject Varithena®, a sclerosing foam. This foam causes the vein walls to harden and collapse. 

Ambulatory Phlebectomy

This treatment removes visible varicose veins by using tiny openings to “hook” the vein with special tools and remove it. Unlike other methods, this one removes the appearance of the vein immediately.

What Results Will I See With Treatment for Swollen Legs? 

If your swollen legs are the result of venous problems, treatment can provide significant improvements. You may start to notice improvements in swelling, aching, and heaviness within a few weeks. Blood flow will redirect away from the treated veins and into healthier veins, improving circulation. 

Is There Any Downtime With Treatment for Swollen Legs?

You can return to most normal activities after treatment, although Dr. Dohner will give you specific instructions based on your treatment. Compression stockings and daily walking will encourage healthy blood flow. You might have minor irritation or bruising over the treated vein.
