Tens of millions of people in the United States are currently living with a chronic breathing disorder. Asthma is one of the most common and can increase your chance of chronic obstructive pulmonary disorder (COPD). Chronic bronchitis and pneumonia are two serious lung conditions that can lead to severe symptoms and possibly death. Symptoms of lung problems can include chest pain, long-lasting cough, wheezing, coughing, and fatigue. Environmental influences, lifestyle choices like smoking, and genetics are often the risk factors behind many breathing disorders.
