What Are the Different Causes of Phlegm?

Sputum is an acute and chronic trachea-bronchitis. Cough, sputum, asthma, and inflammation are common symptoms of lower respiratory tract infections. Lower respiratory tract infections are classified as acute and chronic. Acute infection is mainly acute tracheobronchiolitis, which is the most common disease of the respiratory system. It is mostly caused by infection, physical and chemical irritation, or allergies. It is an acute inflammation of the trachea-bronchial mucosa, which is common in the cold season.

Sputum volume

Right!

The amount of sputum is the amount of sputum. In the human's respiratory tract, many small ciliated wheat waves are heading in the direction of the mouth, slowly pushing the dirty things out, and when they are pushed to the throat, the person will cough and spit. Everyone has a different sputum density, and any kind of bacteria in it may carry it. If you vomit casually, and the sputum dries, thousands of bacteria will float into the air. The length of time that these viruses and germs survive in the natural environment varies, and some can survive in dry sputum for 6 to 8 months; while the Mycobacterium tuberculosis in sputum floats with the dust and can be maintained for 8 to 10 days vitality. To a certain extent, the prevalence of SARS is caused by people's bad health habits.

First, weak constitution and insufficient gas, because the spleen is not transported, the water can stay wet and condense into sputum.

Experts say that sputum is a secretion of the respiratory tract, and healthy people generally have sputum. However, if you have a respiratory disease, you can produce a lot of sputum after being infected by a pathogenic microorganism. There are thousands of germs in the sputum. Sputum can spread atypical pneumonia, tuberculosis, influenza, cholera, measles, etc. Some people spit everywhere, others have the opportunity to inhale pathogenic bacteria to infect them, because pathogenic microorganisms in sputum will evaporate into the air, healthy people breathe some air with pathogens, it is easy to "stroke", sputum is our respiratory tract The excreted waste is a small mouthful of sputum and tens of millions of bacteria. It is not allowed to spit in order to maintain environmental hygiene, but it must not be forced to swallow because the sputum contains a large number of bacteria. It will be killed by gastric juice, but most of the bacteria are still alive, they will enter the intestine and cause intestinal diseases, and if the sputum contains Mycobacterium tuberculosis, it may cause intestinal tuberculosis. These bacteria may also spread to the liver, kidney, meninges and other parts through the blood and cause diseases in these parts. Experts point out that sputum can also be harmful if you do not vomit. If the sputum is not expelled in time, it may cause poor breath and difficulty breathing, which may develop emphysema; cough and repeated cough may cause changes in the alveoli and lead to poor function; some patients' sputum is also antigenic and may cause allergies asthma. Therefore, experts point out that sputum should be "spit as quickly", but be careful not to vomit anywhere. Spit, it's best to wrap it in a paper towel and throw it into the trash.
