Leg swelling
Leg swelling is a buildup of fluid in the tissues of the feet, ankles and lower legs. It is a common symptom with many possible causes.
The most common causes are prolonged standing or sitting, venous insufficiency, pregnancy, hormonal changes, or certain medications. More serious causes include heart failure, kidney disease or a blood clot in a vein (DVT).
Sudden one-sided leg swelling, especially if it is accompanied by pain or redness, may indicate a blood clot and requires immediate assessment.

Frequently asked questions
When is leg swelling an emergency?
Seek immediate care if the swelling is sudden and one-sided, the leg is red and hot, or shortness of breath appears at the same time. These may indicate a blood clot or a pulmonary embolism, which are life-threatening.
How does venous insufficiency cause swelling?
Veins carry blood back to the heart using one-way valves. If the valves do not work properly, blood accumulates in the legs and causes fluid buildup in the tissues. Symptoms include swelling, heaviness, fatigue and varicose veins. Compression stockings, elevating the legs and exercise help.
Do compression stockings help with leg swelling?
Yes. Medical compression stockings are an effective treatment for venous swelling. They improve venous circulation and reduce fluid buildup. The stockings should be put on in the morning before getting up, and they should ideally be selected with the help of an expert to get the correct compression level.
