Allergic cough belongs to the category of allergic diseases. Its obvious symptoms are a dry cough with little sputum and other allergic symptoms, which may include allergic rhinitis symptoms such as nasal congestion, nasal itching and runny nose, or allergic conjunctivitis symptoms. Allergic cough is theoretically curable. Since allergic cough is caused by the patient’s exposure to allergens, it can be completely cured if the patient is removed from the allergen environment. However, if the allergen cannot be avoided, then the cure is very difficult. However, in the vast majority of cases, due to the patient’s environment, the pollution problem is becoming more and more serious and new allergens are emerging, which are very insidious, making it difficult for the patient to completely get away from allergens. In addition, modern people work and live under great stress and their bodies are in a state of relative immune response disorder, and these factors make it very difficult to eradicate allergic cough. However, the condition can be controlled as long as the patient stays away from allergens as much as possible and actively pursues treatment. Treatment generally involves anti-sensitization, anti-inflammatory and cough suppression. Although allergic cough is not life-threatening, as the disease can develop into typical asthma in severe cases, it can seriously affect the patient’s work, life and studies, so once you have allergic cough, you must actively pursue treatment to avoid delays.
