Yes, human lungs can be replaced. This is done through a procedure called a lung transplant.
Understanding Lung Transplants
A lung transplant is a major surgical operation where a diseased lung is removed and replaced with a healthy lung from a deceased donor. [What is a lung transplant? A lung transplant is surgery done to remove a diseased lung and replace it with a healthy lung from another person. The surgery may be done for one lung or for both. Lung transplants can be done on people of almost all ages from newborns to adults up to age 65 and sometimes even later.]
Who Needs a Lung Transplant?
People with severe lung diseases that are not responding to other treatments might be candidates for a lung transplant. These diseases can include:
- Chronic Obstructive Pulmonary Disease (COPD)
- Cystic Fibrosis
- Pulmonary Fibrosis
- Lung Cancer (in some cases)
The Lung Transplant Process
The process is complex and involves rigorous testing and evaluation to ensure the recipient is a suitable candidate. The surgery itself is a lengthy and delicate procedure requiring a highly skilled surgical team. Post-operative care is extensive, including medication to prevent rejection of the transplanted lung.
Limitations of Lung Transplants
While lung transplants offer a life-saving option for many, there are limitations:
- Donor organ shortage: Finding a suitable donor lung is a major challenge.
- Risk of rejection: The recipient's body may reject the transplanted lung. Immunosuppressant drugs are necessary to minimize this risk.
- Surgical risks: Lung transplants are major surgeries with inherent risks, such as infection and bleeding.
