What should you know about cure for shortness of breath?

Breathlessness may come from an airway problem, a chest infection, a heart-related problem, low red blood cells, an allergic reaction, or another condition. [Asthma](/conditions/asthma/) and [COPD](/conditions/copd/) can narrow or inflame the airways, while [Anaemia](/conditions/anaemia/) can reduce oxygen delivery to tissues. A clinician will consider when symptoms began, whether they occur at rest or with activity, chest pain, cough, wheeze, fever, palpitations, and medical history. The right treatment might include an inhaler, treatment for infection, correction of anaemia, or care for a heart or allergic condition.

Stop exertion, sit upright, loosen tight clothing, and try to remain calm while arranging advice. Use a prescribed reliever inhaler exactly as your action plan says; do not borrow someone else’s medicine. Record triggers, timing, associated symptoms, and any reading from a home monitor if one is available. A new or recurring problem deserves clinical review, even if it improves. Conditions such as [Acute Bronchitis](/conditions/acute-bronchitis/), [Bronchiectasis](/conditions/bronchiectasis/), or [Atrial Fibrillation](/conditions/atrial-fibrillation/) may need different assessments.

Call emergency services for severe or rapidly worsening breathlessness, blue or grey lips, fainting, confusion, inability to speak in full sentences, or sudden swelling of the face, tongue, or throat. Chest pressure or pain, especially with sweating or nausea, also needs urgent assessment because it may accompany [Angina](/conditions/angina/) or another emergency. Do not drive yourself if breathing is severely impaired.

Ask what cause is most likely, whether you need breathing tests or heart checks, how to use any inhaler, and which changes should trigger urgent help. Tell the clinician about smoking, allergies, recent infections, medicines, and breathlessness at night or when lying down.
