What Is Phlegm?
Also known as sputum, phlegm is a thick substance that is produced by respiratory system. A normal human being produces their fair share of phlegm; however this frothy substance goes largely unnoticed under normal conditions. It’s only during a respiratory infection that one becomes acutely aware of phlegm. During such instances this fluid is either green or yellow in color. There is also a visible change in its viscosity with the liquid becoming frothy. What distinguished phlegm from other issues that flow from the respiratory system is that, it largely flows from the lungs. The phlegm might have traces of blood in it, and depending on its degree of viscosity the presence of phlegm might obstruct ones ability to properly respire. If you witness the above mentioned symptoms then you are essentially witnessing abnormal phlegm symptoms. Phlegm will ordinarily have substances such as mucus, dead cells, and foreign particles including dust in its system. When you are witness to abnormal phlegm symptoms you need to seek immediate medical advice. This is on account of the fact that this could be a harbinger of a serious medical condition such as lung cancer. This is the worst case scenario though; it could also mean that you are battling with minor medical issues such as an allergy or an underlying medical condition that has exacerbated the condition. Either way seek medical advice when you notice abnormal phlegm conditions. It might just save your life.
