6 – Lung Involvement
A wide range of factors may cause lung involvement in systemic scleroderma.
Some symptoms of lung involvement may include shortness of breath, a decreased tolerance for exercise, and a persistent cough.
Thickening of the lung tissue, fibrosis or scarring may happen due to the overproduction of collagen that usually occurs in scleroderma patients.
This makes it more difficult for the oxygen to travel into the bloodstream. Also, the weakening of respiratory muscles can decrease lung function.
