What is the cause of foamy sputum

Cold and cough are very common phenomena in life. Most people will cough when they have a cold, and they may also cough up phlegm. Sometimes the phlegm is white and has bubbles. In fact, the white foamy phlegm coughed up is likely to be caused by lung infection caused by phlegm in the lungs. Therefore, everyone must pay attention, and parents must be careful when taking care of their babies.

Why do I have a cough with white phlegm?

1. Cold, cough, lung infection, and phlegm.

The main cause of cough is respiratory tract infection, of course 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 there is a cold caused by wind and cold. Colds can cause respiratory tract infections and lung infections, which can cause white sputum to form in the lungs. This is the main reason.

The symptom of coughing and spitting white phlegm is a manifestation of cold phlegm. The phlegm caused by cold phlegm and lung qi deficiency is 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. The main symptoms are frequent coughing, itchy throat, chills and headache, clear nasal discharge or cough with thick, white and thin sputum. White sticky sputum is often caused by mycoplasma and viruses; yellow thick sputum is caused by coccal infection, gray sputum is caused by bacilli, and green sputum is caused by Pseudomonas aeruginosa. Mixed colors indicate mixed infection.

Tips: White sputum should be spit out in time, or you can take some anti-inflammatory drugs or expectorant and cough-relieving oral liquids for treatment. At the same time, you must keep warm. Drink water when you want to cough to suppress the phlegm in the lungs and excrete it through urine. When you have a cold, you should drink more water than usual to expel the virus.

2. Caused by pharyngitis.

Coughing with phlegm may also be caused by pharyngitis. Pharyngitis is a disease caused by bacteria, which can be divided into acute pharyngitis and chronic pharyngitis. Acute pharyngitis is often caused by viruses, followed by bacteria. It is most common in winter and spring. Patients with chronic pharyngitis often clear their throats and spit out white sputum due to increased pharyngeal secretions. It is often secondary to acute rhinitis, acute sinusitis, acute tonsillitis, and is often a complication of infectious diseases such as measles, influenza, and scarlet fever. Its typical symptoms are cough with white sputum, hoarseness, sore throat, etc.

Catching 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.

Tips: It is recommended to go to the hospital for a chest X-ray first to check for any lower respiratory tract infection. If it is a simple chronic pharyngitis, it is recommended to use lozenges such as Yinhuang lozenges, Jinsuozi throat treasures, etc. You can also use Chinese herbal medicines such as Sterculia lychnophora and honeysuckle to make tea. However, you must pay attention to increasing exercise, maintaining adequate sleep and rest, and avoid smoking, drinking, and spicy and irritating foods. At the same time, pay attention to preventing colds and other inducing factors, and pay attention to maintaining indoor air circulation. However, if you experience severe coughing, sore throat, etc., you can take oral medications such as roxithromycin for treatment.

3. Spleen deficiency and body weakness.

Weak constitution and insufficient vital energy can cause moisture to accumulate due to spleen deficiency and stasis, and condense into phlegm, mostly white phlegm. It is recommended to massage the nose and throat more.

Nose massage: Use your bent thumb to massage along the nose bone, both sides, up and down 44 times. Then place your palms on the larynx and massage up and down 66 times. Once in the morning and evening.

4. Cold and dampness like 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.
