Is chronic obstructive pulmonary disease (COPD) hereditary?

A Answers (2)

  • Chronic obstructive pulmonary disease is the chronic blockage of airways in the lungs, causing difficulty breathing and shortness of breath. Smoking is the leading cause of COPD. While rare, a genetic disorder known as alpha-1 antitrypsin deficiency can also cause COPD. Most people have two normal copies of the gene. If you inherit one mutated gene, you are a carrier and can generally prevent COPD by maintaining a healthy lifestyle. However, if two alpha-1 deficient genes are inherited, you will likely develop COPD, despite any lifestyle precautions.
  • Chronic obstructive pulmonary disease (COPD) is not hereditary. COPD results from long-term inhalation of toxins, primarily cigarette smoke. This disease may also be caused by long-term exposure to fumes or dust if inhaled regularly over a period of many years.
