CAUSES AND CONSEQUENCES OF PULMONARY DISEASES

Abstract

Pulmonary diseases represent one of the most pressing and complex challenges in global healthcare, with their etiology rooted in the intricate interplay of genetic, environmental, and infectious factors. This article provides an in-depth scientific analysis of the causes, pathogenetic mechanisms, and consequences of pulmonary diseases such as chronic obstructive pulmonary disease (COPD), asthma, lung cancer, pneumonia, and tuberculosis. Key causes include genetic predispositions (alpha-1 antitrypsin deficiency, CFTR gene mutations), environmental factors (tobacco smoking, air pollution, occupational hazards), and infectious agents (bacteria, viruses, Mycobacterium tuberculosis). The consequences encompass respiratory insufficiency, cardiovascular diseases, and psychological issues at the individual level, as well as economic losses and burdens on healthcare systems at the societal level. The article highlights the importance of preventive measures, including smoking cessation, vaccination, and air quality improvement, while also discussing future research directions such as gene therapy and artificial intelligence-based diagnostic methods. This work emphasizes the need to enhance global healthcare strategies and strengthen environmental protection measures.
