The most frequent warning signs of lung disease are listed below. If you are experiencing any of these symptoms, discuss them with your doctor as soon as possible.
- Chronic Cough - Any cough that has lasted a month is chronic. This is an important early symptom indicating something is wrong with your breathing system, regardless of your age.
- Shortness of Breath - Shortness of breath that continues after a brief rest following normal exercise, or comes after little or no exertion, is not normal. Labored or difficult breathing, the feeling that it is hard to draw air into your lungs or breathe it out, is also a warning sign.
- Chronic Phlegm Production - Phlegm, or sputum, is produced by the lungs as a defense response to infection or irritants. If your phlegm or mucus production has lasted a month, this could indicate an underlying problem.
- Wheezing - Noisy breathing or wheezing is a sign that something unusual is blocking the airways of your lungs or making the airways too narrow.
- Coughing Up Blood (Hemoptysis) - If you are coughing up blood, the blood may be coming from your lungs or upper respiratory tract. Whatever the source of the blood, it signals the onset of a health problem.
- Frequent Chest Colds - If you have more than two colds a year, or if one lasts more than two weeks, you may have an underlying disorder.
