Cough is such a problem that almost every person suffers from at some point in his life. Sometimes cough occurs due to a slight tickle in the throat, and sometimes chest pain occurs due to continuous coughing. Often people ignore cough considering it a minor disease, but sometimes this cough can also be a sign of some problem going on inside the body. Especially when mucus (phlegm) starts coming along with cough, then the question definitely arises in the mind whether the mucus accumulated in the lungs is dangerous and why cough occurs at all. So let us know why we cough and whether the mucus accumulated in the lungs is dangerous for us.
What is cough and why does it occur?
Cough is a natural defense process of our body. When any foreign object like dust, smoke, germs, allergy particles or excess mucus accumulates in our throat or lungs, the body tries to expel it through cough. Cough is the body’s way of cleansing. The main causes of cough are irritation in the throat or respiratory tract, cold or flu, dust, smoke or pollution, allergies, excessive mucus formation in the lungs, increased stomach acid (acid reflux / GERD) and asthma.
What is mucus (phlegm)?
There are two types of cough. In which the first is dry cough, in which mucus does not come out, itching or burning sensation is felt in the throat. Usually caused due to allergy, viral infection or acid reflux. On the other hand, cough with phlegm, in this thick mucus comes out. It is common in diseases like cold, bronchitis, pneumonia. The body tries to expel the dirt from the lungs. Mucus is a thick, sticky substance that forms in the lungs and throat. Its function is to keep the respiratory tract moist and trap and expel dust, germs and allergens. A little mucus formation is normal and necessary.
Is mucus in the lungs dangerous?
Generally, having light and clear mucus in the lungs is not dangerous, because it is part of the body’s natural defense system and helps in keeping the lungs clean. But in some situations, accumulated mucus can become a cause for concern. If the color of the mucus becomes yellow or green, it can be a sign of infection like cold, flu or bronchitis, whereas bleeding in the mucus is a serious condition and it is necessary to see a doctor immediately. Apart from this, if cough persists for more than three weeks, then it can be a symptom of asthma, COPD, TB or heart related disease. If there are symptoms like difficulty in breathing, chest pain, high fever or wheezing sound along with mucus, then it should not be ignored at all.
