Lungs play a vital role in breathing and oxygenating one’s body. Any disorders of this vital organ caused by inflammation can rapidly affect the rest of the body. However, many people may not realize they have lung problems until they become severe. Knowing the early signs of poor lung health can help individuals seek medical attention and prevent further damage. This article discusses some early signs of poor lung health and what they indicate. Here are a few common signs of poor lung health: Shortness of breath:  Difficulty breathing, especially after mild physical activity, could indicate poor lung function. Shortness of breath is also known as dyspnea, and it is a common symptom of many lung conditions, such as chronic obstructive pulmonary disease (COPD), asthma, and pulmonary fibrosis. A cold or flu virus can clog and stress out one’s lungs, causing shortness of breath. This compromised lung capacity can make one more susceptible to developing bacterial infections, including bacterial pneumonia or bronchitis. If one is experiencing shortness of breath, it is crucial to consult a doctor as soon as possible. Inability to breathe deeply:   Poor lung health can make it challenging to fully expand the lungs, resulting in shallow breathing.
