    We continue our discussion with cough. We’ll do the same thing. Mean to say that with dyspnoea, we walked through why dyspnoea could be perhaps found with standing up, lying down, maybe with exertion. With cough, once again, the characteristics and description of how the patient's presenting with cough becomes incredibly important for you. So, along with dyspnoea, cough is another main way for you to diagnose your respiratory disease. Let's continue. Respiratory causes of cough: asthma, COPD, infection, interstitial lung disease. In the overview section, we talked about how these may then give you, while depending on the site of what kind of cough you might have? Asthma, we talked about 2 different types and we will go into these again, atopic or intrinsic. The most common, would be atopic. That’s the one in which, upon exposure to allergens in the society, we have difficulty with breathing. COPD, more chronic. Infections, we talked about atypical and typical. Other causes: allergy, post-nasal drip or even GERD. Don’t forget this. Think about where you are with GERD, in the GI system. Where are you? At the gastro-oesophageal junction. And now the lower oesophageal sphincter is quite weak and therefore acid is then going to do what? Reflux into the oesophagus. And so much so, that it might actually cause irritation to the respiratory tree. Common causes are bolded, but keep in mind that we will go through all the diseases in great detail. We’re just setting up the foundation of cough. We’ll ask the same question here. For cough, is it acute or chronic? Acute then suggests infection or say that your patient is intubated and if your patient is intubated, there is every possibility that those food particles might then aspirate into your trachea.
