Asthma is a chronic condition marked by airway inflammation and sensitivity, often causing breathlessness, wheeze, chest tightness and cough. Below is general information on common symptoms, triggers, how asthma is assessed, and which specialists may be involved in care.
Asthma involves increased reactivity of the airways to various stimuli. Symptoms can wax and wane between episodes; severity varies by age, trigger exposure and coexisting health issues. The course differs from person to person, and management focuses on control and preventing severe episodes.
Typical features include shortness of breath, wheezing, recurrent cough and chest tightness. During a severe attack, breathing difficulty can escalate quickly. Signs that require urgent evaluation include inability to speak in full sentences, bluish lips or nailbeds, sudden worsening of breathlessness, or altered consciousness. In such cases, seek emergency care.
Triggers often include dust mites, pollen, animal dander, tobacco smoke, cold air, air pollution, respiratory infections and some exercise types. Reducing exposure—improving indoor air quality, avoiding smoke, managing infections and identifying personal triggers—helps lower the risk of attacks.
Initial assessment is commonly provided by primary care providers or family physicians. If needed, patients are referred to Pulmonology (Chest/Respiratory Medicine) or Allergy and Immunology for further evaluation. Diagnosis typically relies on history, physical exam and, when indicated, lung function tests such as spirometry.
Identifying triggers, regular follow-up with clinicians and lifestyle adjustments can improve daily comfort and activity levels. Physical activity is usually encouraged with appropriate precautions; schools and workplaces may need reasonable adjustments. Keeping a symptom diary and having a follow-up plan support long-term management.
