What is the reason for long-term cough with white sputum

Long-term coughing with white sputum is generally caused by colds and flu. Because of the respiratory tract infection, it sometimes causes a mild lung infection, and white sputum will appear in the lungs. At this time, you should drink more water and eat more foods that help relieve coughs. Eating more light meals will help cough up phlegm and help the condition gradually improve.

What is the reason for long-term cough with white sputum

1. Coughing up white sputum may be caused by a cold or cough

The main cause of cough is respiratory tract infection, including the lungs. White phlegm in the mouth is mainly caused by phlegm in the lungs, which will be spit out when coughing. It usually happens when a cold is caused by wind and cold. Colds can cause respiratory tract infections and lung infections, and can cause white sputum to form in the lungs. This is the main reason. Coughing and spitting white phlegm is a manifestation of cold phlegm. Cold phlegm and lung qi deficiency will cause the phlegm to be all white. Wind-cold cough is a cough caused by the body's exposure to wind-cold and the failure of lung qi to flow.

2. Coughing up white sputum may be caused by pharyngitis

Coughing with phlegm may also be caused by pharyngitis. Pharyngitis is a disease caused by bacteria and can be divided into acute pharyngitis and chronic pharyngitis. Acute pharyngitis is often caused by viruses and secondarily by bacteria. Catching a cold, fatigue, long-term stimulation by chemical gases or dust, excessive smoking, etc., can reduce the body's resistance and easily promote the onset of the disease. It is recommended to avoid spicy and irritating foods while taking medication. Therefore, coughing with white foamy sputum does not necessarily mean that there is a problem with the lungs. It may be caused by pharyngitis.

3. Coughing up white sputum may be caused by cold and dampness and a preference for fatty, sweet and greasy food.

Cold and dampness may also cause white phlegm, but this phlegm is a bit sticky. If you are overweight or like to eat fatty and greasy food, you may also have a lot of phlegm, and "white phlegm" cannot be ruled out.

4. Coughing up white sputum may be caused by viral infection

Coughing with white foamy sputum does not necessarily mean there is a problem with the lungs. It may be caused by pharyngitis. In addition, many viruses and bacteria can cause coughs, and colds are just one of them. So don't blindly treat coughs as colds. Go to the hospital to check the cause and then take the right medicine to successfully kill the bacteria and viruses.
