cold and cough is a very normal disease. If there is phlegm in the throat, you always want to cough it out. Different colors of phlegm can explain different problems. Let's see how to see the disease from the color of phlegm.
Classification of phlegm:
1. White phlegm
It indicates that there is slight inflammation in the suction duct, which is often a patient with a cold. Because there's a lot of virus in this sputum, as well as a corpse with giant phagocytes, an immune cell. Under the electron microscope, many white blood cells and various types of cold viruses will be found.
2. Thick yellow or green phlegm
It indicates that there is suppurative inflammation in the body, that is, severe aspiration tract infection, tracheitis or bronchitis. This is very different from the lobar pneumonia caused by pneumococcus. It is the suppurative bacteria (Staphylococcus, Streptococcus, Pseudomonas aeruginosa, etc.) that infects the human body and causes suppuration. The pus is dead white blood cells and necrotic tissue.
3. Gray or black sputum
It refers to the deposition of iron dust, carbon dust or dust, indicating the impact of environmental pollution on people. People who spit like this are often patients with occupational diseases. For example, we often hear of silicosis, or textile workers often get fiber lung and so on.
4. Red sputum - urgent treatment for bleeding
There is no doubt that the red sputum is bloody. Doctor's note: any hemorrhagic cough is a symptom that needs urgent treatment. Although a strong and intense cough will rupture the microvasculature at the back of the throat and cause bleeding, which is not a very serious thing, it is better to ask a professional doctor for diagnosis when encountering hemorrhagic cough.
5. Pink sputum with bleb indicates pulmonary edema
When coughing, it coughs up air bubbles and pink sputum, and at the same time, it has the phenomenon of short suction. It feels like drowning, which is likely to be the warning sign of pulmonary edema. When the lungs are full of liquid due to the failure of heart power, pulmonary edema will appear.
6. Bloody phlegm
If it is not caused by oral trauma, it is mostly tuberculosis. Because TB bacteria can invade human lungs, especially cause serious damage to alveoli.
As we all know, the human body inhales oxygen into the body through the breathing system, and then through the blood lung circulation, so that the red blood cells in the blood vessels carry the oxygen stored in the alveoli to complete the oxygen supply to the whole body. Therefore, blood vessels must be combined with alveoli to complete aspiration. Once the alveoli are destroyed, the blood vessels will naturally penetrate into the lungs, and then the patients will cough up the blood flowing into the lungs like choking water.
In the early stage, patients with tuberculosis coughed bloody sputum. In the middle stage, they coughed up blood directly. In the late stage, the whole baby's lungs had been destroyed by tuberculosis bacteria, and a large number of spitting blood, even spitting blood, could spit up half of the spittoons.
7. Rust jelly sputum - pneumonia
According to experts, if the expectorated sputum is reddish brown, rusty or brown, and jelly like, the cause should be pneumonia caused by pneumococcus. When suffering from this disease, chest pain and fever are often accompanied.
8. No phlegm - dry cough or aspiration of foreign matters
If a child suddenly has a dry cough, be wary of inhaling foreign bodies. If the cough lasts for more than three or four days and there is fever, it may be caused by acute respiratory tract infection. A chronic cough that lasts for more than two or three weeks and does not cough up any sputum may indicate tumorigenesis, heart disease, or neurotic habits. The doctor said that if you have not coughed before, and recently you have coughed because you have a cat and a dog at home or you have just moved to a new house or bought new furniture, it is likely that you are allergic to these new things.
