What should you know about heavy chest shortness of breath?

Breathlessness may come from narrowed airways such as Asthma or COPD, an infection such as Acute Bronchitis, or reduced oxygen-carrying capacity in Anaemia. Heart-related conditions such as Angina or Atrial Fibrillation can also cause chest discomfort or breathlessness. Anaphylaxis may cause breathing difficulty with swelling, hives, or dizziness. These symptoms do not establish a diagnosis by themselves.

Stop exertion, sit upright, loosen tight clothing, and seek help from someone nearby. Use only medication prescribed for this situation and follow its written instructions. Note when symptoms began, what you were doing, and whether pain spreads to the arm, jaw, back, or shoulder. Arrange medical assessment even if symptoms improve when the episode is new, recurrent, or unexplained.

Call emergency services now for severe or rapidly worsening breathlessness, crushing or persistent chest pressure, blue or grey lips, fainting, confusion, coughing blood, or inability to speak comfortably. Treat breathing difficulty with facial or throat swelling as an emergency. Do not wait for a routine appointment or drive yourself when symptoms are severe.

Ask which examinations or tests are needed, whether your heart and lungs require separate assessment, and what symptoms should trigger emergency help. Share your medical conditions, medicines, allergies, smoking or vaping exposure, and any pattern with exertion or meals.
