Senile emphysema, also known as senile pulmonary emphysema or senile obstructive pulmonary disease (COPD), refers to a chronic and progressive lung condition predominantly affecting older individuals. This ailment is characterized by the irreversible enlargement of the air sacs in the lungs, leading to shortness of breath, coughing, and wheezing. Synonymous terms for senile emphysema encompass chronic obstructive pulmonary disease, pulmonary emphysema, and chronic bronchitis. All of these terms describe the same underlying disease process. While synonyms may exist, it is important to consult with healthcare professionals to accurately diagnose, manage, and treat this respiratory disorder that can significantly impact one's quality of life.
