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.
