Prolonged cough may be a sign of asthma

Dr. Tran Thi Hong Thanh – Internal Medicine Specialist – Dang Van Ngữ School of Medicine, said:

Bronchial asthma is a chronic inflammation of the airways, involving a variety of inflammatory cell types and cell components, mainly Mast cells, eosinophilic white blood cells (E), T lymphocytes, macrophages, neutrophils (N) and bronchial epithelial cells. The disease is common at any age and in sensitive locations.

This inflammatory process is accompanied by increased bronchial reaction with many irritants that cause bronchial smooth muscle spasms, airway obstruction leading to shortness of breath, cough, chest tightness in episodes of recurrence, often nocturnal and early morning, can recover on their own or due to treatment.

Bronchial asthma belongs to an allergic disease, accompanied by bronchitis. During an asthma attack, it is often difficult to breathe out. When having shortness of breath is accompanied by hissing (due to bronchospasm) and respiratory discharge causing coughing, there is phlegm. The disease occurs all year round but every time the weather changes or encounters favorable factors (allergies), asthma attacks appear. This disease is most commonly detected at night at midnight in the morning.

The reason is that the midnight time in the morning of the reaction of the respiratory tract is the highest. The air at night is dry, the euphoria of the nervous system that governs the trachea is also higher. Patients with asthma when developing often have difficulty breathing, have a hissing sound, chest aches, can not lie still but have to sit up to breathe.

Bronchial asthma is also easily confused with the exacerbation of chronic obstructive pneumonia, because this disease when having an acute attack also causes difficulty breathing, wheezing, coughing. The cough has solid phlegm, yellow, blue, cough usually more than 3 months / year.

If frequent coughing lasts more than a few days or any signs or symptoms of asthma, see your doctor. Treating asthma early, can prevent long-term lung damage and help keep the health condition from worsening over time.
