Maybe everyone will feel so disgusting, but this is good for doctors to diagnose the disease.

Sputum color see disease

1. White sticky sputum

Indicates a slight inflammation of the respiratory tract, often a cold. Because there are a lot of viruses in this sputum and the bodies of macrophages (an immune cell). Under the electron microscope, many white blood cells and various types of cold viruses are found.

2. Yellow or green thick sputum


It indicates that there is suppurative inflammation in the body, which is heavy respiratory infection, bronchitis or bronchitis. This is very different from the pleuropneumonia caused by pneumococcal bacteria. It is a purulent bacterium (common staphylococcus, streptococcus, Pseudomonas aeruginosa, etc.) that infects the human body and becomes purulent. The pus is the dead white blood cell and necrotic tissue.

3. Gray or black sputum

For the deposition of iron, charcoal or dust, it indicates the impact of environmental pollution on people. People who spit such sputum are often patients with occupational diseases. For example, we often hear about silicosis, or the fiber lungs that textile workers often get.

4. Red sputum - for bleeding needs urgent treatment

The red sputum is undoubtedly a bloodstain in the sputum. The doctor reminds: any hemorrhagic cough is a symptom that needs urgent treatment. Although intense coughing will cause the microvessels behind the throat to rupture and cause bleeding, it is not a serious matter, but it is better to encounter hemorrhagic cough. Ask a professional doctor to diagnose.

5. Pink sputum - and with bubbles to predict pulmonary edema

When coughing, it will cough up bubbles and have a pink sputum, and at the same time there is a shortness of breath. It feels like drowning. It is probably the warning sign of pulmonary edema. When heart failure causes the lungs to be filled with fluid, the pulmonary edema is Appeared.

6. Bloodshot sputum

If it is not caused by oral trauma, it is mostly tuberculosis. Because tubercle bacilli can cause encroachment on the lungs of the human body, especially causing severe damage to the alveoli.

We all know that the human body inhales oxygen through the respiratory system, and then through the blood circulation of the blood, 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, the blood vessels must be combined with the alveoli to complete the breathing. Once the alveoli are destroyed, the blood vessels naturally penetrate into the lungs. After that, the patient will desperately cough up the blood flowing into the lungs like water.

Early tuberculosis patients are sputum with cough blood, and will cough up blood in the middle. In the late stage, the whole lungs have been destroyed by tubercle bacilli, and a large amount of vomiting blood, even hematemesis, can vomit small semi-sputum.

7. Rust-colored jelly-like sputum - should be pneumonia

According to experts, if the sputum coughed out is reddish brown or rusty, brown, and jelly, the cause should be pneumonia caused by pneumococcal disease. When suffering from this disease, it is often accompanied by chest pain and fever.

8. No sputum - light dry cough or aspiration of foreign bodies

If a child suddenly develops a dry cough, be alert to whether it is inhaling foreign matter. If you continue to cough for more than three or four days and have a fever, it may be caused by an acute respiratory infection. If you continue to cough for more than two or three weeks and do not cough up any sputum, a chronic cough may indicate a tumor, heart attack or neurological habit. The doctor said that if you have not coughed before, and recently coughing because of raising cats and dogs at home or just moving new houses and installing new furniture, it is probably because of allergies to these new things.
