Also known as: Pedal Edema
Swollen feet occur when fluid accumulates in the foot tissues. While often caused by prolonged standing or sitting, persistent swelling may indicate heart, kidney, or liver problems.
Foot and ankle swelling is extremely common and increases with age. Gravity causes fluid to pool in the lower extremities, especially after prolonged standing or sitting.
Bilateral (both feet) swelling is often caused by systemic conditions like heart failure, kidney disease, liver disease, or venous insufficiency. Medications such as calcium channel blockers and NSAIDs can also cause fluid retention.
Unilateral (one foot) swelling is more concerning and may indicate deep vein thrombosis, infection, or local injury, warranting more urgent evaluation.
There are several possible reasons you may be experiencing Swollen Feet. Here are the most common ones.
Gravity causes fluid to pool in feet and ankles, especially during long periods without movement.
Weakened heart cannot pump blood effectively, causing fluid buildup in the legs and feet.
Impaired kidneys fail to filter excess fluid, leading to generalized swelling including the feet.
Damaged leg vein valves allow blood to pool, causing chronic ankle and foot swelling.
These approaches may help manage swollen feet at home. Always consult a healthcare provider if symptoms persist or worsen.
Raise feet above heart level for 20-30 minutes several times daily to promote drainage.
Graduated compression stockings prevent fluid accumulation in the feet and ankles.
Excess sodium promotes fluid retention. Aim for less than 2,300 mg daily.
Physical examination, blood tests for kidney and liver function, echocardiogram for heart function, and venous ultrasound for vascular causes.
Seek immediate care if swelling is sudden and severe, affects only one leg (possible DVT), is accompanied by chest pain or shortness of breath, or skin becomes red and warm.
Steps you can take to reduce the likelihood of experiencing swollen feet.
Move regularly during long sitting periods
Elevate feet when resting
Reduce sodium intake
Stay physically active
Wear compression stockings during travel
