Asthma 2024 Guidelines

Asthma is a chronic inflammatory airway disease that causes variable airflow obstruction, bronchial hyperresponsiveness, and reversible bronchoconstriction. It commonly presents with episodes of wheeze, cough, chest tightness, and breathlessness, often triggered by allergens, viral infections, exercise, cold air, smoke, NSAIDs, beta-blockers, or occupational exposures. In this video, we simplify asthma from the basics, including the key pathophysiology, why symptoms vary over time, how to confirm the diagnosis objectively, and how chronic asthma is managed using modern anti-inflammatory inhaler strategies such as AIR and MART therapy. We will cover: What asthma is Type 2 airway inflammation Role of IL-4, IL-5, IL-13, IgE, eosinophils, and mast cells Airway oedema, mucus plugging, and bronchoconstriction Airway remodelling in chronic asthma Clinical features and common triggers Why symptoms are worse at night or early morning Objective diagnosis using spirometry, FeNO, eosinophils, bronchodilator reversibility, PEF variability, and bronchial challenge How to differentiate asthma from similar respiratory conditions Chronic asthma treatment using AIR and MART therapy When to consider LTRA, LAMA, and specialist referral This video is designed for medical students, MRCP candidates, junior doctors, and anyone trying to understand asthma in a simple, clinically relevant way.
