Generally, there is no sputum in the early stage of cough, but when the symptoms are gradually serious, bronchitis will metabolize a lot of sputum due to safeguard measures and will cough up phlegm immediately. When the respiratory infection intensifies, the number of orange staphylococcus in the respiratory system increases, and the expectoration will contain some yellowish bacteria, so the sputum will turn yellow and will continue to be sticky and fishy. However, when coughing yellow phlegm turns white, what is it? Is yellow phlegm more serious or white phlegm more serious?

Yellow sputum is more serious than white sputum, which is generally not accompanied by bacterial infection, while yellow sputum is often accompanied by bacterial infection, which needs attention and antibiotic treatment if necessary. The difference between white phlegm and yellow phlegm mainly includes the following points: first, white phlegm is white, with foam sputum mostly, and it is not sticky, while yellow phlegm is yellow, which is mostly sticky and smelly; Second, the imaging examination of patients with cough with white phlegm will generally not find obvious abnormalities, and patients with cough with yellow phlegm may have increased lung texture and large inflammation. Patients with long-term expectoration need medical treatment to avoid delaying their illness.

In fact, there are many colors of sputum, such as rust color, emerald green, bright red and dark brown. The natural yellow sputum usually means that there is bacterial infection in the respiratory system. When there is bacterial infection in the respiratory system, our body will stimulate immune function, and this kind of cellular immunity is just like us.

It is often said that the white blood cell count, in the case of attacking bacteria, a lot of such white blood cells are killed, which is called pustules in medicine. This kind of pustules will show pale yellow, so the pale yellow comes from this.

White sputum usually means that the patient may have bacterial infection, may not have bacterial infection, may have other infections, or may have no major problems. Therefore, it is impossible to completely distinguish the light and heavy level of the patient's illness from white sputum and yellow sputum. For example, a patient with a serious virus infection does not have yellow sputum. For example, if the infection is killed, the patient does not have yellow sputum, but the condition is also very risky.

Naturally, many people cough up white sputum, even in the condition of physical and mental health. Yellow sputum usually means bacterial infection, but the condition of such bacterial infection can be light and repeated, which can cause respiratory failure. The light patient may be controlled quickly with antibiotics, so the condition cannot be completely distinguished from the color of sputum, depending on the overall lung function of the patient and the more serious level of infection. ?
