Prolonged dry cough: causes
Coughing for a long time is a warning sign. What are the reasons for it?
What are the causes of a prolonged dry cough?
A long-term cough is one that does not stop for more than two months. It appears as a result of irritation of receptors that are located in the mucous membrane of the larynx, trachea and bronchi. Some people think that a prolonged dry cough will go away on its own. Far from it. If a dry cough does not go away for a long time, an urgent need to consult a doctor. A similar symptom is not only a consequence of respiratory diseases (tuberculosis, laryngitis, tracheitis, bronchitis, whooping cough). Allergies, stress, oncology, pleurisy, heart failure, sinusitis, sinusitis, and even diseases of the gastrointestinal tract can cause prolonged coughing. It can also occur if a person has been in a dusty room with dry air for a long time. And when foreign objects get into the lungs, a paroxysmal cough immediately appears.
Allergic cough usually appears in the morning, and disappears when the allergen is excluded. At the same time, constant contact with an irritant that causes an allergic reaction leads to bronchitis and asthma.
What diseases can cause dry cough?
Dry cough in people suffering from diseases of the cardiovascular system has distinctive features. This cough occurs after exercise, along with shortness of breath, rapid heart rate and pain in the heart. Sometimes a cough is accompanied by bloody discharge, which indicates problems in the left ventricle. Also, a prolonged dry cough in the absence of an increase in body temperature becomes the cause of pathological changes in the aorta (aneurysm).
A dry cough can be caused by a thyroid disorder that puts pressure on the trachea. People with gastrointestinal problems may cough after eating.
The worst thing is that a prolonged cough can lead to serious cancer (for example, cancer of the lung, bronchi or throat). In this case, the person is tormented not so much by a dry cough as by a painful and continuous cough. It is dangerous to start such a cough, so at the first symptoms you should immediately consult a doctor. He will prescribe X-rays and treatment based on the results of the examination.
