What is the cause of excessive white sputum

It is quite uncomfortable to have too much white phlegm and be unable to cough it out or swallow it. The causes of excessive white phlegm include colds, lung heat coughs, weak coughs, or people with some lung diseases, which will also show symptoms of excessive white phlegm.

1. Cold and cough: That is what Western medicine calls, filterable viruses invade the upper respiratory tract, causing a series of reactions in the body's immune system. The secretion of the tracheal and nasal mucosa increases, and the patient develops symptoms such as runny nose, nasal congestion, and sputum. Because of the phlegm, the throat makes reflex movements such as contraction and coughing in order to clear the phlegm. At the same time, the body attempts to kill the bacteria by raising its temperature (fever). This will continue until the virus is defeated.

2. Cough due to lung heat: This situation is very common. The difference between a cough caused by lung heat and a cough caused by a cold is that a cough caused by lung heat may not be accompanied by symptoms such as body aches, fever, alternating chills and fever, etc.; instead, it is accompanied by signs of "dryness and heat" such as dry mouth, bitter taste in the mouth, sore throat, and yellow and thick phlegm. The reason why lung heat causes coughing is that the body is too hot and the mucosal tissue is congested, which gives bacteria an opportunity to invade.

3. Weak cough: This situation is different from the above two types of coughs. People who cough due to qi deficiency and kidney deficiency will not cough loudly, heavily, or with great pain. They will only make two slight and continuous "coughs". The patient always feels itchy in the throat. If he talks too much or runs a few steps, his throat will feel uncomfortable and he can't help coughing lightly. When you cough up, you may have slightly grayish-black phlegm. This type of cough can last forever and stay with you for the rest of your life.

4. Lung disease: Cough caused by serious diseases such as pneumonia, tuberculosis, lung cancer, etc. At this time, coughing is just one of the symptoms.
