Stem Cell Therapy for COPD in Thailand

Cigarette smoking is the primary cause of COPD, with tobacco smoke triggering chronic inflammation, destroying alveolar walls (emphysema), and stimulating excess mucus production (chronic bronchitis) over years of exposure.

Long-term exposure to occupational dust, chemicals, and industrial fumes contributes to COPD development in non-smokers and accelerates disease in those with smoking history.

Indoor and outdoor air pollution, including biomass fuel combustion used for cooking and heating in many parts of the world, causes chronic lung inflammation and progressive airway damage.

Alpha-1 antitrypsin deficiency, a genetic condition affecting approximately 1-2% of COPD patients, reduces the lungs' natural protection against inflammatory damage, leading to early-onset emphysema.

Chronic airway inflammation creates a self-perpetuating cycle where damaged lung tissue releases inflammatory mediators that recruit more immune cells, causing further tissue destruction even after the initial trigger is removed.

Progressive breathlessness that initially occurs only with exertion but gradually worsens until even basic activities like getting dressed, walking short distances, or climbing a few stairs become exhausting.

Chronic cough that persists for months or years, often productive with sputum that may be clear, white, or discoloured during exacerbations, frequently dismissed as a "smoker's cough" until lung function is significantly impaired.

Wheezing and chest tightness, particularly during physical activity or when exposed to cold air, dust, or other respiratory irritants.

Frequent respiratory infections and exacerbations that require antibiotics, oral steroids, or hospitalisation, each episode potentially causing a stepwise decline in lung function that may not fully recover.

Fatigue and reduced exercise tolerance that extend far beyond respiratory symptoms, affecting energy levels, appetite, and overall quality of life.

In advanced stages, weight loss, muscle wasting, ankle swelling, and cyanosis (bluish discoloration of the lips and fingertips) reflecting the systemic impact of chronic oxygen deprivation.
