What should you know about global initiative for asthma?

Asthma symptoms can come and go because sensitive airways narrow and become inflamed. Wheezing, cough, chest tightness, and breathlessness may be triggered by exercise, infections, smoke, allergens, weather changes, or workplace exposures. Allergic rhinitis and house dust mite allergy can coexist with asthma, while a chronic cough may have several other causes. A symptom such as wheezing indicates an airway sound, not a diagnosis by itself. Assessment considers the pattern, examination, breathing tests when appropriate, and response to treatment.

Use prescribed inhalers exactly as instructed and check your technique at reviews. Keep an agreed written action plan that explains your regular medicine, what to do when symptoms increase, and when to seek help. Reduce known triggers where practical, avoid smoke, and ask about vaccinations and exercise suited to your condition. If symptoms are not controlled, arrange a review rather than repeatedly relying on quick-relief medicine without advice. A nebuliser treatment may be used in selected acute situations under clinical guidance.

Seek emergency help if you cannot speak comfortably because of breathlessness, your lips look blue or grey, you feel confused or exhausted, symptoms rapidly worsen, or your reliever is not helping as directed. Sit upright, follow your action plan, and do not drive yourself if breathing is severely difficult. Prompt review is also appropriate when night symptoms, activity limitation, or frequent flare-ups are developing.

Ask how to tell asthma symptoms from an infection or allergy, whether your inhaler technique is correct, and which triggers to record. Ask when to change treatment during a flare, whether you need breathing tests, and exactly when emergency services should be called.
