Carbon buildup worsens lungs of COPD patients

Scientists have found significantly higher levels of carbon buildup in the lung cells of COPD patients compared to smokers without the disease, potentially worsening lung function. The study revealed that alveolar macrophages in COPD patients contained over three times more carbon deposits than those of smokers. This carbon accumulation was linked to larger cells and increased inflammation, suggesting pollution may contribute to the disease. Researchers believe this carbon buildup may be due to impaired clearance or increased exposure to particulate matter. Further studies are needed to understand the long-term effects and potential causes of this phenomenon.
