updated: 12/04/2019

Phlegm is a common condition. Coughing is usually a natural reflex of the human body in order to push the dust or object out of the body. The cough may be simply due to the body being irritated, but it may also be a sign of serious illness, especially phlegm cough. Phlegm cough may be a symptom of a common cold, but it may also be bronchitis or some other respiratory diseases. If the phlegm cough persists, the health of the patient will be negatively affected.

Therefore, the early treatment of disease is essential. However, not everyone knows how to overcome this condition, so in this article, we will give you the simple but effective home remedies which have been proven by so many people to help you treat phlegm cough . Before that, you had better understand some basic information about this problem.

What Is Phlegm Cough?

Before learning about phlegm cough, let’s find out what phlegm is. Phlegm is the secretion of the respiratory tract, which consists of mucus, red blood cells, white blood cells, etc., which are expelled from the respiratory tract after coughing. The phlegm will pass through the esophagus and be excreted by the gastrointestinal tract. Phlegm may be the result of many respiratory causes such as lung abscess, pulmonary embolism, pneumonia, bronchial asthma, and bronchiectasis[1] [2].

Usually, the respiratory tract of anyone produces phlegm, but not much, so our respiration is not blocked, and we do not have a cough. However, when there are too many phlegm secretions, you will cough, even cough continuously. When the respiratory tract is sick or when at different times of the disease, the phlegm will change in its color, dilution, and taste. If you look closely at that change, you can identify the disease, and so you can identify the right treatments. Phlegm cough is more dangerous than dry cough. It quickly leads to obstruction and death if the phlegm builds up in the throat without being pushed out.

What Are Common Causes Of Phlegm Cough?

Causes of phlegm cough are due to increased secretion of mucus in the throat. Too much phlegm will cause the throat to be blocked and the respiratory process of the body is prevented. When phlegm in the throat becomes more than the normal level, the body generates a natural reflex: coughs. At this point, the larynx is enlarged powerfully to expel phlegm. However, phlegm in the throat is often mucus and usually sticks to the throat, so coughing is very difficult to expel phlegm outside. Therefore, we often have the urge to cough continuously until the phlegm is removed from the throat. Then we get the unpleasant feeling. At this point, we will cough less or stop coughing. However, after the phlegm is thrown out, the other phlegm continues to be created which irritates to the throat. This process lasts for a long time. It causes tiredness and discomfort for the patient, especially at night, the cough makes patients unable to sleep.
