When people find themselves short of breath after activities that they used to do with no problem, they want to write it off as a sign of aging – but that would be a mistake. In this episode of Inside Scope, host Dr. Daniel Haight talks with Pulmonary and Critical Care physician Dr. James Brown about COPD and interstitial lung disease, different conditions that both cause shortness of breath. An accurate diagnosis is important, Dr. Brown says, because finding the cause allows pulmonologists to ease their patients’ suffering and help them have a better quality of life.
