A smoker sees his doctor because he has a persistent cough and is short of breath after very little exertion. What diagnosis will the doctor make and what can the person expect if he does not quit smoking?
What will be an ideal response?
The person is suffering from chronic bronchitis, which causes the dyspnea and coughing. If he does not stop smoking, he can expect frequent pulmonary infections, more coughing, and progressively worse dyspnea (all symptoms of chronic obstructive pulmonary disease). Ultimately, he can expect to develop hypoxemia, CO2 retention, and respiratory acidosis. He may develop emphysema or lung cancer.
