Dr. Costello treats diseases and conditions of the chest. This includes things such as pneumonia, asthma, tuberculosis, emphysema, and complicated chest infections. Pulmonology is a sub-specialty of internal medicine concerned with diseases of the lungs and bronchial tubes, which often involve the evaluation of the upper respiratory tract (nose, pharynx, and throat) and the heart.
Asthma is a chronic lung disease that inflames and narrows the airways. Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning. Asthma affects people of all ages, but it most often starts during childhood. In the United States, more than 25 million people are known to have asthma. About 7 million of these people are children.
