The most common symptoms of ILD are cough and shortness of breath, symptoms that are similar to more common respiratory diseases such as asthma, COPD or emphysema. ILD can mimic recurrent pneumonia leading to a delay in diagnosis. If you have an interstitial lung disease, you might experience:
- Dry cough
- Shortness of breath
Lung function tests, blood tests, imaging, and other diagnostics can aid in determining whether you have an interstitial lung disease. Chest X-rays and CT scans typically show abnormalities that involve more than one region of the lungs. Lung function testing, while normal in mild cases, may show reduced lung volumes and low oxygen levels.
