Cough is a defense mechanism that arises from irritation in the airways, larynx, trachea, pleura, and partly due to the same innervation cough can also cause irritation of the external auditory canal – for example, when cleaning the ear canal cotton swab. It serves to protect the airway in the event that they are stranded foreign body or irritated airway wall in some other stimulus. Its basis is a sharp exhale while simultaneously sealed the voice slot. This increases the pressure in the lungs, and any foreign body or mucus expectoration may be outside the airways. Cough is a normal part of infection, when the wall of the respiratory tract is due to their susceptibility and relatively easy mounting options infections often attacked. Therefore, his presence in such a situation is the rule rather than the exception. When, though, is cause for concern? If the cough is astringent, very very irritatingand long term. If a strong cough is also associated with high fever, schvácenosti states, it is most likely a bronchopneumonia (popularly pneumonia). This diagnosis but must be determined by a physician based on X-rays. Sometimes the cough occurs but alone, without concomitant infection, fever or other symptoms (symptoms) associated with infection, and lasts a long time and often irritable – what then? This kind of cough is often found in heavy smokers, exhibits maxima morning and during the day waning. But if there is more than one month, it is still just as strong, just as irritating and still no signs of improvement, it is necessary to think about the possibility of cancer or metastasis in the airways. And cancer metastasis need not be just a matter of smokers, there are many kinds of cancers that metastasize to the lungs – to name cancer, kidney or liver disease.
Smokers are most often found small cell, which has a miniature size, it is wrong to find, but shows considerable aggression and ability to metastasize (mostly in the brain). This type of cancer is very dangerous, because due to the nominated properties is very fast killer.
If we leave the plane carcinomas, metastasis and infection, is another cause of coughs chemical irritation of the respiratory tract – each organism is sensitive to other compounds, generally cough cause gases in the air, whether the “normally” present – such as fumes automotive, and gases, that get into the air for chemical accidents.
Irritation induces airway great attacks in people with asthma.
If you suffer from cough at a time when our immunity is naturally lowered (spring, fall, winter, season flu epidemic), we need not be unduly alarmed, it’s just part of the overall disease. If you suspect bronchopneumonia, should consult a doctor as soon as possible, which would confirm the diagnosis and began treatment as soon as appropriate. If you are worried that you may have cancer or metastasis in the airways (and if you are a smoker, you have been diagnosed with any other type of cancer someone in your family has suffered from a given cancer), urgently (!!!) to locate doctor. The word is urgently with three exclamation marks, because if indeed the tumor process confirmed timely therapy in some cases the only thing that can save lives.
Prolonged cough is a very important symptom, certainly no excuse from a doctor’s visit, saying: “It’s just a cough with it does not go to the doctor!”
