Chronic lung disease may include COPD (chronic obstructive pulmonary disease), which is chronic bronchitis and emphysema. It may also include pulmonary fibrosis, sarcoidosis, pulmonary hypertension, cystic fibrosis, and other long-term respiratory conditions. When you have chronic lung disease, it's normal to have good days and bad days. Take care of yourself emotionally and physically. You can take steps to feel more in control of your health and your situation. Remember that your health care team, family, and friends are there to help. Don't be afraid to share your feelings and ask for support.
