About 140,000 men and women in the U.S. have pulmonary fibrosis (PF) , a progressive disease that occurs when thick, stiff scar tissue forms in the lungs, making it difficult to breathe.  Scar tissue forms around the tiny air sacs called alveoli that enable gas exchanges to occur between blood and the lungs. People with PF often have low levels of oxygen in their blood, especially in advanced stages of the disease, which can cause additional organ damage.
The disease typically affects people between the ages of 50 and 75 years, and while the disease may progress slowly in some people, others don’t survive beyond five years from the initial diagnosis unless they have a lung transplant. While there is no cure, recent research in the advancement of adult stem cell therapy has shown that restoration of damaged and dying cells through is possible. PF does not have to be frightening and debilitating. Adult stem cell therapy is a treatment designed to help the body’s natural repair kit work more effectively.
What Are the Symptoms?
The most common symptoms of pulmonary fibrosis are shortness of breath and difficulty breathing, both of which grow much worse as the disease progresses. Other symptoms include 
- dry, persistent cough
- shallow breathing
- gradual weight loss
- aching muscles or joints
Symptoms and their severity can vary from patient to patient; some people develop severe symptoms very quickly, while in others, the disease may take months or even years to become severe.
Pulmonary fibrosis cannot be cured, and treatments are focused on slowing disease progression, reducing symptoms and maintaining quality of life. Medications may be prescribed to help reduce inflammation, and oxygen supplementation can help make breathing easier and more efficient when blood oxygen levels reach dangerously low levels. Oxygen can also help people be more active to help decrease anxiety and preserve lung function. Some patients with pulmonary fibrosis develop other problems, such as a collapsed lung, blood clots in the lungs (pulmonary emboli), lung infections, pulmonary hypertension and even lung cancer and heart failure.
Pulmonary rehabilitation is also typically prescribed, typically including breathing exercises, medical guidance and counseling to help patients cope with their disease and prognosis. In some patients younger than 65 years who have no other serious medical issues, lung transplant may be considered when medications are not effective.
