Wheezing in the throat are additional breathing noises due to narrowing of the airways or the presence of any pathological contents in them. The occurrence of wheezing is observed in cases where, for some reason, the passage of air directly into the airways becomes almost impossible.
Quite often, people who have never suffered from a respiratory tract disease may experience what is called relapsing wheezing. Their causes may be different. For example, they can cause a general narrowing of the airways. This is most often observed in various viral diseases, as well as in lung diseases (usually chronic) and bronchial asthma.
In addition, wheezing can also be caused by local narrowing of the same airways. Often this happens with tumors or when directly into the respiratory tract of a foreign body. Therefore, the first step is to determine the cause of their occurrence.
Wheezing in the throat should in no way be ignored. And in case of their occurrence, it is necessary to consult an experienced doctor who will conduct an examination with a stethoscope. This is required in order to determine the degree of narrowing of the airways themselves. In addition, this allows you to correctly prescribe a course of treatment.
Sometimes, when such wheezing is detected, a study of lung function is required . As a rule, wheezing in the throat of a child cannot be caused by flu or another viral disease. Therefore, the examination must be carried out especially carefully to identify the true cause of their occurrence.
In medicine, it is customary to distinguish between dry and wet rales. The first is always evidence of a narrowing of the lumen of the bronchi, which can be caused by deformation of their walls in case of pneumosclerosis. And also dry rales can indicate that the walls of the bronchi are compressed by the tumor, but this is quite rare.
More often, wheezing in the throat can be caused by swelling of the mucous membrane as a result of an inflammatory process or an allergic reaction. Also, dry rales indicate that there are some lumps or threads of viscous sputum in the lumen of the bronchi. And with bronchitis or bronchial asthma, bronchospasm is often observed.
Typically, such wheezing is heard on exhalation, but very rarely can they be heard in the inspiratory phase. They differ in musical timbre, have a humming, buzzing (presence of sputum) and wheezing (bronchospasm, narrowing of the small bronchi) sound. According to doctors, the nature of such wheezing changes significantly after coughing.
Listening to wheezing is necessary in order to not only correctly diagnose a particular ailment, but also correctly evaluate the effect of the applied expectorant and bronchodilator drugs.
In turn, wet rales are the result of foaming with a stream of air when inhaling a liquid directly in the airways. It can be exudate, transudate, blood and others. These fluids can be not only in the airways themselves, but also in the pathological cavities of both lungs.
Hoarseness in the throat may indicate bronchiolitis, as well as pneumonia, congestion of the lung or its heart attack. To correctly identify the ailment, you should especially carefully listen to the characteristic sounds of wheezing. Best of all, as a rule, they are auditioned precisely on inspiration. And depending on how much fluid is contained, what caliber of the bronchi or the volume of the cavities, small, medium and large bubble rales are distinguished.
So, small bubbling rales are similar to the noise emitted from sparkling water in a glass of gas bubbles. Medium- and coarse-bubble ones resemble the sound of air bubbles that burst if blowing into the water through a thin straw. And they differ, respectively, in a very narrow or wider clearance. In the event of a sharp exacerbation of wheezing of one nature or another, urgent medical attention is required.
