Chronic obstructive asthma

Asthma narrows the airways through muscle tightening, swelling of the airway lining, and mucus production. Symptoms may vary from day to day and can flare with allergens, viral infections, exercise, cold air, smoke, or strong smells. Allergic rhinitis and house dust mite allergy may coexist and make airway symptoms harder to control. Persistent obstruction means airflow remains limited between flares or does not return as expected; this needs careful assessment because other lung conditions can produce similar symptoms. A clinician may use breathing tests and the symptom pattern to guide the diagnosis.

Use controller and reliever medicines exactly as prescribed, and ask a clinician to check your inhaler technique. Keep a written action plan that explains your usual treatment, early warning signs, and escalation steps. Note exposure to dust, smoke, pets, infections, or exercise, along with night waking and reliever use. Reduce indoor smoke and irritants, and manage nasal allergy if it contributes to symptoms. Do not stop a controller suddenly or rely on a reliever more often without medical advice. A nebuliser may be used in selected situations, but it is not a substitute for an agreed asthma plan.

Use your emergency plan and seek urgent help for severe breathlessness, difficulty speaking, blue or grey lips, confusion, collapse, or symptoms that are rapidly worsening. Arrange prompt review when reliever treatment is needed more often, night symptoms increase, wheezing persists, or normal activity becomes difficult. Chest tightness with sweating, faintness, or severe pain also needs urgent assessment because it may not be asthma.

Ask: Is my airflow obstruction reversible, and which tests will clarify this? What is my daily controller plan? How can I recognise a flare early? Could allergic rhinitis or dust-mite exposure be contributing? When should I use a nebuliser or attend urgent care?
