Swollen legs or ankles are common and can happen for many different reasons. Sometimes it’s temporary and harmless, such as after standing or sitting for a long time. But persistent or unexplained swelling can sometimes be a sign of an underlying medical problem that deserves attention.
One condition that can cause swelling is advanced liver disease. When the liver is severely damaged, changes in blood proteins and fluid balance can contribute to fluid accumulating in the legs and ankles. However, swollen legs do not automatically mean you have a liver problem.
What Can Cause Swollen Legs?
Leg swelling, medically called edema, occurs when excess fluid collects in the tissues.
Some possible causes include:
- Sitting or standing for long periods
- Excessive salt intake
- Certain medications
- Vein problems, including chronic venous insufficiency
- Heart conditions
- Kidney disease
- Liver disease
- Pregnancy
- Lymphatic system problems
- A blood clot in a leg
Because there are so many possible causes, the swelling itself isn’t enough to determine what’s wrong.
