Breathlessness and tight chest: what it can mean

Asthma can narrow the airways and cause tightness, wheeze and difficult breathing. Acute bronchitis may produce cough and a heavy chest during an infection. COPD and bronchiectasis can cause persistent breathlessness, especially with mucus or repeated chest infections. Anaemia can reduce oxygen delivery and leave a person short of breath or tired. Angina may cause pressure or tightness with exertion, while atrial fibrillation can cause an irregular heartbeat and breathlessness. Anaphylaxis can develop quickly with swelling, hives, wheezing or throat tightness. These symptoms overlap, so the pattern and examination matter.

Stop exertion, sit upright and loosen restrictive clothing. Use a prescribed reliever inhaler according to your action plan. Note when the tightness began, what you were doing, whether it spreads, and whether cough, fever, palpitations, swelling or rash is present. Avoid driving yourself if symptoms are severe. Do not assume acidity or anxiety is the cause until urgent problems have been considered.

Get emergency help for severe or rapidly worsening breathlessness, chest pressure that does not settle, pain spreading to the arm, jaw or back, fainting, confusion, blue lips, or a fast irregular heartbeat with weakness. Sudden throat or tongue swelling, wheeze or widespread hives may signal anaphylaxis and needs immediate treatment. Seek same-day medical advice for a new tight chest, symptoms at rest, or breathlessness that is limiting normal activity.

Ask whether your symptoms suggest airway narrowing, a heart problem or anaemia, and whether you need an ECG, blood test or breathing assessment. Clarify your inhaler plan and the exact symptoms that should prompt emergency help.
