Breathlessness on Exertion

Overview

Breathlessness on exertion is a sense of not getting enough air or having to work harder to breathe when active — walking uphill, climbing stairs, or doing tasks that used to be easy. It can come from the heart or the lungs, and sometimes from anaemia or poor fitness. New or worsening exertional breathlessness always needs assessment, because it can be an early sign of a heart or lung problem even when it feels mild. This page focuses on the cardiovascular angle; the general symptom of shortness of breath is covered under Respiratory & Breathing Problems.

Common causes

• Cardiac causes — heart failure, coronary disease and heart-valve problems.
• Respiratory causes — asthma, COPD and chronic bronchitis.
• Anaemia and low haemoglobin.
• Poor physical fitness and deconditioning.
• Obesity, which increases the work of breathing on activity.
• An over-active or under-active thyroid.
• Deconditioning after a long illness.

Symptoms and associated features

The pattern matters. Cardiac breathlessness tends to come on with exertion, may worsen progressively, and can be accompanied by ankle swelling, palpitations, or breathlessness that wakes you from sleep and forces you to sit upright. Breathlessness with wheezing points to the lungs; breathlessness with pallor and tiredness points to anaemia; and breathlessness with weight gain and cold intolerance points to a thyroid cause.

Evaluation and investigations

Evaluation combines a history and examination with an ECG, a chest examination, blood tests (complete blood count, thyroid function, kidney function) and a chest X-ray where indicated. An echocardiogram is arranged when a cardiac cause is suspected, and spirometry when a lung cause is suspected. See ECG Evaluation for Symptoms, Respiratory & Breathing Problems and Abnormal Test Results.

Management overview

Management treats the cause. Cardiac causes are managed with medication and specialist cardiac care; asthma and COPD are managed with inhalers; anaemia is corrected; a thyroid disorder is treated; and deconditioning and obesity are addressed with a graded activity and weight plan.

Follow-up and monitoring

Follow-up tracks the response to treatment and confirms the breathlessness is improving. Persistent or worsening exertional breathlessness is reviewed and referred for specialist assessment when appropriate.

Warning signs — seek urgent care

• Breathlessness that comes on suddenly or at rest — urgent.
• Breathlessness with chest pain, sweating or a rapid irregular pulse — urgent.
• Breathlessness that wakes you from sleep and forces you to sit upright — urgent.
• Breathlessness with fainting, bluish lips or very low oxygen — emergency.
