Asthma

Asthma, fully known as bronchial asthma, is a chronic airway disease characterized by chronic inflammation of the airways, leading to airway narrowing, impaired lung ventilation, and difficulty breathing. Asthma often causes recurrent episodes of wheezing, shortness of breath, chest tightness, or coughing, which frequently occur or worsen at night or in the early morning. Most patients experience spontaneous relief or relief after treatment.
