Swollen Feet

Overview

Swollen feet are the commonest form of swelling people notice. Typically both feet and ankles puff up as the day goes on, feel tight in shoes, and ease overnight or with elevation. Often the cause is benign — prolonged standing, heat, venous pooling, or a medicine — but new, persistent, one-sided or worsening foot swelling needs assessment because it can be the first sign of a heart, kidney, liver or thyroid problem. This is the canonical page for foot and ankle swelling; Swollen Ankles and Foot Swelling redirect here, and the broader lower-limb pattern is covered on Leg Swelling.

Common possible causes

• Prolonged standing or sitting, and heat.
• Venous insufficiency and varicose veins.
• Heart failure — both-foot swelling with breathlessness.
• Kidney disease — swelling with foamy urine or abnormal tests.
• Liver disease and low blood protein.
• An under-active thyroid.
• Medicines — calcium-channel blockers, steroids, certain painkillers, hormone therapy.
• Pregnancy.
• Local causes — infection (cellulitis), injury, or a clot (more often one-sided).

Symptoms and associated features

Both-foot swelling that worsens through the day and eases overnight is usually dependent. Features that raise concern include swelling that no longer eases overnight, one-sided foot swelling, breathlessness, reduced urine output, foamy urine, weight change, and swelling with pain, redness or warmth. A single puffy foot after a long flight or immobilisation needs prompt assessment for a clot.

Evaluation and investigations

Evaluation combines a history and examination with targeted tests — kidney function, urine ACR, serum albumin and liver function, complete blood count, thyroid function, blood sugar, and — where indicated — a heart marker, ECG, echocardiogram, or leg Doppler for one-sided swelling. See Abnormal Test Results.

Management overview

Management treats the cause. Dependent and venous swelling respond to elevation, movement, compression socks and reduced salt; systemic causes are treated specifically; medication-related swelling is addressed by medical review and adjustment; and a clot or infection is treated promptly. Fluid tablets are used only when appropriate and under medical supervision.

Follow-up and monitoring

Follow-up confirms the swelling is settling and the cause is controlled. Persistent or worsening foot swelling is reviewed and referred for specialist care when appropriate.

Warning signs — seek urgent care

• One-sided foot or calf swelling that comes on suddenly with pain, warmth or tenderness — possible clot; urgent.
• Foot swelling with breathlessness, especially on lying flat — urgent.
• A swollen foot with redness, heat and fever — possible infection; urgent.
• Swelling with chest pain or fainting — emergency.
