Allergic bronchitis in children is a condition where the airways in the lungs become inflamed due to an allergic reaction. It is usually triggered by allergens such as dust, pollen, pet dander, mold, or smoke. When a child breathes in these allergens, the immune system overreacts, causing swelling of the bronchial tubes and increased mucus production. This leads to symptoms like persistent cough, wheezing, chest tightness, and shortness of breath, especially at night or early in the morning.Avoi
