The lung is like a big umbrella, located in the human chest, protecting other internal organs, providing the human body with the needed oxygen, and expelling carbon dioxide from the blood. In addition, the lung is also a filter for external bacteria and viruses. It filters harmful substances in the air and is the first line of defense for human organ health.
But it is very fragile. Long-term smoking, kitchen fume, and air pollution will constantly damage our lungs. At present, the incidence rate of lung cancer is rising in the world, and the most serious problem is that many lung cancers were found in the late stage.
If four phenomena occur frequently, it is necessary to do a lung CT examination as soon as possible!
1. Frequent cough:
In daily life, when we smell a pungent smell, it usually causes a severe cough, but this cough can be quickly relieved.
But if you always cough frequently for a period of time, especially when sleeping at night, and even affects your sleep, you should pay more attention. This may be caused by lung damage, please don't take it seriously.
2. Throat swelling and pain:
Cold and laryngitis can lead to sore throat, but it can be improved after taking medicine. If the sore throat is very obvious for a period of time, lung damage should be considered. Harmful substances, bacteria, and viruses in the lungs will retrogress to the throat through the trachea, causing inflammation of the throat mucosa, and resulting in swelling and pain in the throat.
3. Phlegm with blood:
Some metabolic wastes of the respiratory system can be metabolized out of the body through sputum, so expectoration is a very normal situation. However, if you find obvious red blood filaments in the sputum, it may be closely related to abnormal lung function. Please don't take it seriously.
As the saying goes, it is very important to protect the lung and strengthen their maintenance of the lung at this time because of the changeable weather and the high incidence of various lung diseases in the spring.
4. Phlegm in the throat and abnormal sputum
Everyone will have phlegm, which is the liquid secreted by the throat and is used to absorb dust and other impurities in the air. However, sputum caused by lung disease often has some abnormal conditions. For example, red and bloodshot sputum is often caused by pulmonary tuberculosis or bronchiectasis, while black and gray sputum may be caused by inhalation of dust or carbon powder. Beware of asbestos lung and other problems.
If there is always brick red sputum when coughing up sputum, and it is thick and jelly-like sputum, it is critical to be alert whether it is infected with pneumonia bacilli and induce pneumonia. It is important to see a doctor as soon as possible to receive anti-infection treatment.
