Every puff of cigarette smoke delivers toxic chemicals deep into your lungs—triggering a cascade of damage that most people don’t realise until it’s too late. Dr. Ferghal Armstrong dives into the devastating effects of smoking on lung health, from early symptoms like chronic cough to advanced stages of chronic obstructive pulmonary disease (COPD) and emphysema.You'll learn how cigarette smoke impacts the respiratory system, destroying protective cilia, paralysing the mucociliary escalator, and overwhelming the lungs' ability to repair themselves. Discover the difference between chronic bronchitis and emphysema, how they contribute to irreversible lung damage, and why many patients don’t get diagnosed until their breathlessness is severe.This video also explains the clinical side: how spirometry detects obstructive patterns, how CT scans reveal emphysematous changes, and why smoking cessation is the only proven way to slow disease progression. We cover genetic risk factors like alpha-1 antitrypsin deficiency, the dangers of secondhand and thirdhand smoke, and how smoking during pregnancy affects fetal lung development.Whether you're a healthcare student, medical professional, or someone affected by smoking, this is your complete guide to understanding the long-term respiratory complications of smoking—and how to protect yourself and others.Chapters00:00 – How Cigarette Smoke First Damages the Lungs00:28 – Lungs: The Organ Most Exposed to Smoking00:51 – The Respiratory Defense System and Cilia Destruction01:10 – Chronic Bronchitis: A Structural Disease01:33 – COPD Explained: Chronic Bronchitis + Emphysema01:52 – Emphysema: Alveolar Breakdown from Smoke02:24 – Symptoms and Clinical Progression of COPD02:47 – Asthma and the Smoking Connection03:04 – Asthma-COPD Overlap Syndrome (ACOS)03:14 – Smoking and Respiratory Infections03:32 – Idiopathic Pulmonary Fibrosis and Smoking03:44 – Cellular and Inflammatory Pathways of Damage04:15 – Genetic Susceptibility and Alpha-1 Antitrypsin Deficiency04:38 – A Typical COPD Patient Case05:02 – Diagnostic Tools: Spirometry, Imaging, and Blood Gases05:15 – Why Smoking Cessation Matters Most05:26 – Secondhand and Thirdhand Smoke Effects05:58 – Impact of Smoking During Pregnancy06:15 – Clinical Advice for Early Detection and Prevention06:59 – Patient Awareness: Link Smoking with Breathlessness07:09 – Teaser for the Next Episode: Smoking and Reproduction

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
