We all have a cough, for example, when we have a cold or after a run. So do you pay attention to these inadvertent and prolonged coughs? If you have a history of allergies, then you need to be careful. This prolonged cough is likely to develop into a form of asthma – allergic cough – and if you then go to the hospital it will be a little too late. What are the symptoms of allergic cough First let’s look at the clinical manifestations of allergic cough: allergic cough, also known as cough variant asthma, is a special type of asthma, the main symptoms of which are persistent or recurrent coughing attacks for at least a month, often at night or early in the morning with a clear cough, little sputum, coughing aggravated after exercise, no clinical manifestations, or after a longer period of time when treatment with antibiotics is ineffective and can only be treated with bronchial Patients often have personal or family allergies, so these people need special attention. The treatment of allergic cough is similar to that of asthma in that the principles are to identify allergens, control cough attacks and prevent recurrences. The causes of asthma are multifaceted and therefore complex to investigate, so all we can do is avoid allergens as much as possible, and at the same time treat them in a timely manner, avoiding all possible infections, such as smoking and cold drinks. In case of an asthma attack, appropriate bronchial medication can be used to relieve bronchial spasm, reduce edema and inflammation, and reduce the secretion of mucus. Persistent or recurrent cough attacks usually last for more than 1 month, and in some cases the condition worsens at night, especially in the middle of the night. Generally speaking, the cough may worsen in the early morning or after exercise, with no clinical phenomena and no obvious positive signs on physical examination, which should not be detected. It is difficult to cure this particular type of asthma because it has many variations and doctors are often anxious. If you have a personal history of allergies or a family history of allergies then you must be careful, as long as there is a continuous cough for more than a month, then you must go to the hospital for a careful examination and never delay the disease, otherwise this allergic cough can be excruciating.
