To put it simply, white phlegm is the manifestation of our usual cold and fever, bronchitis and pneumonia in the early stage. This is basically a very common cold and fever, which can be recovered after simple treatment, and it is easy to treat without causing any impact on our health. Therefore, it is reasonable to say that white phlegm is light, which means that the critical degree of the body is very light.
Yellow phlegm basically represents our body, and there is a serious problem, which means that an organ of our body is inflamed, especially the lungs and bronchi. At the later stage of bronchitis and pneumonia, yellow phlegm will appear, which means that our body has been inflamed. Through simple cephalosporin or other drugs, it has no good effect, and we need to cooperate with professional means and drugs in the hospital. At this time, we can't treat it ourselves, so we should consult a professional doctor in the hospital as much as possible to get a quick result.
Black is not a good phenomenon. Most people will not see this phenomenon. It means that there is something wrong with their lungs. People who smoke for a long time may be ebony, and then this phenomenon means that their lungs have been seriously corroded. If a film is made, it is obvious that his lungs are not the same color as those of healthy people. Therefore, the probability of this kind of person getting lung cancer is dozens of times higher than that of normal people. So the color of phlegm can really represent the health of the body.
