 Good morning friends, on occasion of World COPD day, today I want to highlight some of the important aspects of this disease. COPD is the third most common cause of mortality worldwide and in coming few years it will become a second most common cause of mortality. Still many of the people in the world and most majority of the population is unaware of this disease and many of the times this disease was diagnosed when patient visited or admitted for some other cause or some other illness in a hospital or visited in an OPDI. Even many of the healthcare workers don't know how to diagnose a case of COPD. COPD is a preventable and for sure a treatable disease. The risk factors for COPD are majorly a cigarette smoking, also the hookah smoking, then the environmental air pollution, then the occupational dust exposures, metallic fume exposures and other type of noxious chemical exposures are the major cause. Pulmonary function test is the gold standard for diagnosing COPD, early diagnosis and treatment is a life changing experience for a patient. It will improve the quality of life and also it will add years to life. Major symptoms of this disease are breathlessness, breathlessness is progressive in nature, it initially starts with breathlessness on exertion but as the disease advances, patient is not able to get out of her bed also and it's very difficult to go to washroom also in these type of patients associated with cough and expectorations in some patients and this disease has chronic acute exacerbation sometimes which can lead to hospitalizations in between. Also these patients have multiple comorbidities associated with this like cardiac problems are also there with this disease and also these patients have high chances of getting depression in the long term as these patients are socially isolated because they don't want to walk and they don't want to meet people. So they remain isolated in their home and in their houses and in their room. So they become a patient of depression in the long term. So now dear friends I want to share the key to suspect COPD patients. Any patient or person who is more than 45 years of age with new onset breathlessness with exposure to risk factors for as described earlier can be a case of COPD. We must visit our doctor to confirm the presence of this disease as early in your life as possible. Thank you.
