Why is phlegm yellow?

It is very uncomfortable to produce phlegm, especially when the throat is blocked, and sometimes it can cause difficulty breathing. Phlegm is not saliva. It is a respiratory secretion that is relatively sticky and is mainly caused by infection of the human respiratory tract. Generally speaking, yellow sputum is mainly caused by a Staphylococcus aureus infection. Next, let’s take a closer look at why human phlegm is yellow?

First of all, phlegm is a relatively viscous secretion from the respiratory tract. Yellow sputum indicates obvious infection, especially upper respiratory tract infection. Generally, yellow sputum is caused by Staphylococcus aureus infection. The thickening of lung markings on X-rays is also a manifestation of infection. I don't know what your usual living habits are like. I should say that generally yellow sputum will get better with the use of antibiotics and a period of self-healing. What about black sputum? What is it like? Does the black phlegm appear long after a meal or right after a meal? This is important information for judgment. It is best not to go to KTV for the time being, because singing loudly can easily cause laryngeal edema, which is not good for recovery from the disease.

So what should you do if you cough up phlegm, especially yellow phlegm?
