? Nowadays, with the serious air pollution and bad habits such as smoking, lung disease has become a chronic disease of modern people, and cough with excessive phlegm has become a more common problem. With the dry climate in spring, lung diseases such as dry mouth and nose, dry cough and no phlegm all come, which seriously affect health. Phlegm is the secretion of respiratory tract or lung infection. Too much sputum will be sticky and difficult to cough up, and it will easily breed more bacteria in the trachea. At this time, the human body will activate the self-protection mechanism to expel phlegm from the body, which will lead to too much phlegm. What are the reasons?

? 1. Lung problems

? If you feel that the sputum in your throat is constantly increasing in your daily life, but you can't cough it up, accompanied by white sputum and unclean cough, you need to consider whether the lungs are affected, because the lungs of the human body should be in a moist state. If it appears some abnormal phenomena of dryness and heat, it will lead to the external manifestations of poor breathing and difficult cough.

? 2. Spleen and stomach deficiency

? Some people have purulent sputum in their throats, which is caused by the weakness of the spleen and stomach. Because there is something wrong with the food they eat, there is a situation of purulent sputum in their throats. Because of spleen and stomach deficiency, there are too many purulent sputum in the throat, so we should eat as little as possible all kinds of cold foods to avoid damaging the function of the spleen and stomach, so as to make the symptoms of purulent sputum more obvious and prominent.

? 3. Improper diet

? Compared with the previous life, the quality of modern life has improved, and it is normal to have big fish and big meat, and even some people have a diet status of "no meat, no spicy food, no unhappiness". This eating habit is likely to cause people's daily nutrient intake to exceed the standard seriously, resulting in overnutrition, which is also an important reason why many people's weight keeps rising. In addition, eating habits such as overeating and heavy taste will not only burden the human digestive system, but also lead to endogenous dampness, which will cause phlegm to accumulate in the body. Therefore, the daily diet should be rationalized and scientific, especially for patients with phlegm-dampness constitution, so as not to aggravate the symptoms of phlegm-dampness.
