Stages of Pulmonary Fibrosis
Pulmonary fibrosis is a medical condition in which the tissue in the lungs becomes thick and scarred. This results in decreased lung function and, in some cases, shortness of breath and coughing. The condition is progressive and can be fatal if left untreated. Understanding the four stages of pulmonary fibrosis can help you manage your condition and get the best care possible.
Stage 1: Mild Fibrosis
At this stage, the thickening and scarring of the lung tissue is still mild. Symptoms may be mild and may include a dry or productive cough, shortness of breath, and fatigue. The lungs are still able to function adequately and breathing tests may not show any abnormalities.
Stage 2: Moderate Fibrosis
At this stage, the tissue thickening and scarring has become more severe. Symptoms may be more severe, including a dry or productive cough, shortness of breath, and fatigue. The lungs are still able to function, but breathing tests may show some abnormalities.
Stage 3: Severe Fibrosis
At this stage, the tissue thickening and scarring is severe and the lungs are unable to function adequately. Symptoms are severe and may include a dry or productive cough, shortness of breath, and fatigue. Breathing tests may show significant abnormalities.
Stage 4: End-Stage Fibrosis
At this stage, the tissue thickening and scarring is so severe that the lungs are no longer able to function adequately. Symptoms may be severe and life-threatening and breathing tests may show significant abnormalities. This is the most advanced stage of pulmonary fibrosis and can be fatal if left untreated.
