What are the four stages of coughing to self-healing

Cough is a common respiratory symptom that may resolve on its own (i.e., "self-healing"). The term "self-healing" is generally used for illnesses, and there are many diseases that cause cough, some of which can heal on their own, such as the common cold. There is no clear "four stages" in the process of relieving cough symptoms.

Cough can expel secretions or foreign bodies from the respiratory tract, has the effect of clearing irritants in the respiratory tract and resisting infection, and it is a protective nerve reflex action of the human body.Cough can be caused by diseases of the upper respiratory tract, tracheobronchial tubes, lungs, pleura, cardiovascular and central nervous systems.

Common cough-causing diseases such as acute laryngitis, allergic rhinitis, acute bronchitis or bronchitis, tuberculosis (early stage), mycoplasma pneumonia, pleurisy, etc. usually do not heal spontaneously, and need to be treated for the cause after a clear diagnosis, and the cough can be relieved after the primary disease is controlled. Coughing can also be caused by foreign bodies in the airways and inhalation of irritating gases, which can often resolve spontaneously after the foreign body is expelled and the irritating environment is removed. The cough caused by the common cold can disappear in more than 1~2 weeks.

If the cause of the cough is unknown and cannot be relieved for a long time, it is necessary to go to the hospital for further diagnosis and treatment in time.
