I am a smoker and have been coughing for longer period. Will it be chronic bronchitis?

Hello,

Welcome to icliniq.com. You said that you smoke since, from the age of 15, so the diagnosis goes more in favor of chronic bronchitis. The symptoms are also typical of chronic bronchitis. But you have not mentioned any associated allergic symptoms like running nose or frequent sneezing as it suggests bronchial asthma. The best test to differentiate between both is to do a spirometry test, also called PFT (pulmonary function test). It will give a definitive final diagnosis. Regarding treatment, if it is bronchitis, the first and most important thing is to quit smoking. If it is asthma, then you need to take a controller inhaler regularly. Also, you should get done with your chest x-ray. I hope after reading this, you will take the initiative for quitting smoking and quit it ultimately. I hope this helps. The probable cause is smoking. The investigations to be done are chest x-ray PA (posteroanterior) view. Spirometry PFT (pulmonary function test). The differential diagnosis may be COPD (chronic obstructive pulmonary disease). Treatment plan include stop smoking and start with inhalers.
