Why cough?

We all sometimes come across coughs for colds, flu, or other diseases. But why cough?

In this article we will try to figure out why a cough can arise, what it is and what kind of disease it can be.

What is a cough

Cough is a reflex function of our mucous membrane and respiratory tract. At its core, it is a forced expiration. Nature cough is provided as a reaction to a foreign body stuck in the airways. It is thanks to coughing that a person can spit out a bone that has hit the wrong side. However, if an infection was the cause of respiratory tract irritation, the mucosa will react in the same way, although coughing may not help in this case.

Types of cough

Before we talk about a symptom of a disease may be a cough, you should determine its type. Today in medicine there are several types of cough:

  • Productive and unproductive. A productive cough is characterized by sputum formation. Such a cough is often called wet.From the point of view of the doctor, this type of cough is better than a dry cough. Dry or unproductive cough is characteristic in that it does not cause sputum production.
  • Due to sputum can detect the disease. Also, expectoration is evidence that a person gets rid of an infection that is inside the body (for colds and flu).
  • Paroxysmal and obsessive. Obsessive cough refers to this type of cough, which is characterized by the so-called sore throat. It is usually difficult for a person to restrain tickling and he begins to cough, which causes additional irritation of the respiratory mucosa. However, paroxysmal cough is more alarming. It usually occurs suddenly and may indicate that there is a foreign body in the airways. Also paroxysmal cough may indicate the development of whooping cough.
  • With dyspnea and without dyspnea. A cough that is characterized by shortness of breath can indicate problems of the cardiovascular system, as well as increased bronchial activity, which indicates bronchial asthma.

Diseases characterized by cough

There are many diseases for which cough of various types is characteristic. As a reaction to the irritation of the so-called cough receptors in the sinuses of the nose and larynx, a cough may indicate sinusitis, rhinitis, pharyngitis and other progressive diseases.

  • If the cough is dry and the attacks are accompanied by chest pain, this may be a signal of developing tracheitis. With bronchitis, the cough can also be dry, but the sound is deeper. By the way, the disease can also be determined by the sound of coughing. For example, a coarse barking cough is characteristic of laryngitis.
  • No less important is the nature of the flow of cough. If at first the cough was dry and then turned into a wet cough without the use of any expectorant or sputum thinners, then pneumonia could be a likely diagnosis. With her, a dry cough often develops into a wet cough with sputum. This causes pain in the lungs.
  • Finally, a cough can be a signal of aspiration of a foreign body, usually such a cough is characterized by a dull sound, when a person coughs because of aspiration, he tries to cough up from the baby, which got into the airways. Also such a cough can be characterized by redness on the face, gag reflex.

Thus, coughing as an independent symptom may indicate a multitude of illnesses, so if the cause of the cough is not clear, then it is recommended to consult a doctor.
