  • Lung Disease/Respiratory Problems

    Lung Disease/Respiratory Problems Definition and Description of Lung Disease/Respiratory Problems Lung disease refers to an array of conditions that affect the lungs and respiratory system, inhibiting their ability to function optimally. Medical definitions describe lung disease as any disorder that interferes with normal breathing or oxygen exchange. Common respiratory problems include chronic bronchitis, asthma, emphysema,…

  • Emphysema

    Emphysema Definition and Description of Emphysema Emphysema is a chronic lung condition that is part of the group of diseases known as Chronic Obstructive Pulmonary Disease (COPD). It is characterized by the gradual destruction of the alveoli, or air sacs, in the lungs, leading to a decrease in the surface area available for gas exchange.…

  • A1AT Deficiency

    A1AT Deficiency Definition and Description of A1AT Deficiency Alpha-1 Antitrypsin Deficiency (A1AT deficiency) is a genetic disorder that results in insufficient levels of alpha-1 antitrypsin (A1AT), a protein produced in the liver. A1AT serves as a critical inhibitor of enzymes that can damage tissues, particularly in the lungs and liver. Without adequate A1AT, individuals may…

  • COPD

    COPD Definition and Description of COPD Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease that obstructs airflow and hinders normal breathing. It is primarily characterized by long-term respiratory symptoms and limitations in airflow due to the inflammation and damage to the lungs and airways. The term encompasses conditions such as emphysema and chronic…

  • Alpha-1-Antitrypsin Deficiency

    Alpha-1-Antitrypsin Deficiency Definition and Description of Alpha-1-Antitrypsin Deficiency Alpha-1-Antitrypsin Deficiency (AAT deficiency) is a genetic disorder that results in low levels of alpha-1-antitrypsin (AAT), a protein produced by the liver. This protein plays a crucial role in protecting the lungs from damage caused by infections and inflammation. Individuals with AAT deficiency are at a higher…

  • AAT

    AAT Definition and Description of AAT Alpha-1 Antitrypsin (AAT) is a protein produced in the liver that serves as a crucial part of the body’s defense against proteolytic enzymes, particularly elastase, which can damage lung tissue. AAT deficiency is a genetic disorder that results in insufficient levels of this protein, making individuals more susceptible to…
