Swelling with Breathlessness

Overview

Swelling that comes with breathlessness is a combination taken more seriously than swelling alone, because it often points to the heart or the kidneys. In heart failure, fluid builds up in the legs and the lungs, causing both leg swelling and breathlessness — worse on exertion or lying flat, and sometimes waking the person from sleep. In kidney disease, fluid retention can cause swelling and breathlessness together. The combination is assessed promptly. This page covers the combined presentation; the individual symptoms are explored on the linked pages.

Common possible causes

• Heart failure — leg swelling with breathlessness, worse on exertion or lying flat.
• Kidney disease with fluid retention — swelling with reduced urine output.
• A clot in the lung (pulmonary embolism) — sometimes with one-sided leg swelling and sudden breathlessness.
• Liver disease with fluid overload.
• Severe anaemia, which can cause both breathlessness and ankle swelling.
• A flare of a chronic heart, kidney or lung condition.

Symptoms and associated features

Breathlessness worse on lying flat (orthopnoea) or that wakes the person from sleep points to heart failure; swelling with foamy urine and reduced urine points to a kidney cause; sudden breathlessness with one-sided leg swelling or chest pain points to a clot in the lung; and breathlessness with pallor and tiredness points to anaemia.

Evaluation and investigations

Evaluation combines a history and examination with targeted tests — a heart marker (BNP/NT-proBNP), ECG and echocardiogram, kidney function, urine ACR, serum albumin, complete blood count for anaemia, blood sugar, and a chest X-ray. A leg Doppler and lung imaging are arranged when a clot is suspected. See Palpitations & Cardiovascular Symptoms, Respiratory & Breathing Problems and Abnormal Test Results.

Management overview

Management treats the cause. Heart failure is managed with heart medication and, when appropriate, supervised fluid measures; kidney disease is treated to protect function and remove retained fluid; a clot is treated with blood thinners; anaemia is corrected; and liver disease is managed specifically. Fluid tablets may be used under medical supervision when the cause is clear.

Follow-up and monitoring

Follow-up confirms the fluid is clearing, the breathlessness is easing, and the underlying cause is controlled, with periodic re-checking of heart, kidney and relevant markers. Persistent or worsening symptoms are reviewed and referred for specialist care when appropriate.

Warning signs — seek urgent care

• Swelling with breathlessness at rest or that wakes you from sleep — urgent.
• Swelling with sudden breathlessness and chest pain — possible clot in the lung; emergency.
• Swelling with a rapid irregular pulse or fainting — emergency.
• Swelling with bluish lips or very low oxygen — emergency.
