    Shortness of breath (Dyspnoea)

    At Mayo Clinic Healthcare in London, our cardiology and respiratory specialists work together to evaluate and treat shortness of breath, also known as dyspnoea. Using advanced diagnostic testing and a collaborative approach, our team aims to identify the underlying cause of breathlessness and develop a personalised plan for care.

    • Shortness of breath is the sensation of not being able to breathe comfortably or get enough air. While it may occur occasionally during physical exertion, persistent or unexplained breathlessness can sometimes indicate an underlying medical condition, particularly involving the heart or lungs.

      You may benefit from an assessment for shortness of breath (dyspnoea) if you:

      • Become breathless with minimal exertion
      • Feel short of breath while lying flat
      • Experience sudden or severe breathlessness
      • Feel tightness in your chest
      • Have a history of heart or lung disease

      Dyspnoea is most often related to heart or lung diseases, so a comprehensive evaluation is important to determine the underlying cause.

    • Symptoms of dyspnoea may include:

      • Difficult breathing or feeling unable to get enough air
      • Rapid, shallow, or laboured breathing
      • Chest tightness or discomfort
      • Breathlessness at rest or during light activity
      • Worsening symptoms when lying down

      Unexplained breathlessness may occur during activity, at rest, or suddenly without warning. While it can sometimes be linked to exertion or anxiety, persistent or unexplained breathlessness may signal an underlying cardiac or respiratory condition. Early assessment can help to identify the cause and provide the right answers. 

      Associated symptoms may include:

      • Palpitations
      • Dizziness
      • Cough
      • Wheezing
      • Swelling in the legs

      You should seek urgent medical attention if shortness of breath is sudden, severe, or accompanied by chest pain, fainting, or confusion. 

    • Dyspnoea and unexplained breathlessness can arise from a wide range of conditions. Most often, they are linked to problems with the heart or lungs.

      What cardiac conditions can cause shortness of breath?

      • Heart failure
      • Coronary artery disease
      • Heart rhythm disorders (arrhythmias)
      • Cardiomyopathy
      • Heart valve disease

      What respiratory conditions can cause shortness of breath?

      • Asthma
      • Chronic obstructive pulmonary disease (COPD)
      • Pneumonia
      • Pulmonary embolism (blood clot in the lungs)
      • Pneumothorax (collapsed lung)
      • Interstitial lung disease

      What other conditions can cause dyspnoea?

      • Severe allergic reactions
      • Anxiety or panic disorders
      • Obesity
      • Muscle weakness from inactivity

      Symptoms can sometimes overlap. It is important to speak to our clinicians to determine whether the cause is cardiac, respiratory, or both.

    • Your doctor at Mayo Clinic will take a full medical history and a thorough physical examination to diagnose your dyspnoea. If needed, our clinicians will recommend specific tests based on your symptoms.

      These tests may include:

      • Cardiopulmonary exercise test (CPET) to see how well your heart and lungs work during activity
      • Spirometry (lung function test) to determine your lung function and whether there is an obstruction in your lungs
      • An ECG to assess your heart rhythm and electrical activity
      • An echocardiogram to check the structure and function of your heart
      • Blood tests to check for anaemia, infection, or markers of heart strain

      With support from cardiology and respiratory professionals, we will determine if your unexplained breathlessness is due to cardiac, respiratory, or a combination of causes.

    • Treatment will depend on the underlying cause of your shortness of breath. Because causes can vary, your consultant may recommend several tests to confirm your diagnosis.

      Treatment options may include:

      • Medication to improve lung or heart function
      • Inhaled medications for airway conditions
      • Treatment of abnormal heart rhythms
      • Anticoagulation therapy if deemed appropriate
      • Lifestyle modifications and risk factor management

      Your Mayo Clinic specialist will create a personalised treatment plan tailored to optimise your symptoms, minimise your risk, and support your long-term health and well-being. 

    • To help prevent the start or continuation of unexpected breathlessness, you can:

      • Stop smoking
      • Stay away from pollutants
      • Avoid extreme temperatures
      • Exercise regularly
      • Take any prescribed medications correctly and consistently
      • Regularly check in on your breathing
