Question

Quizplus · Accepted Answer

The symptoms described in the question are characteristic of asthma, which is caused by narrowing of the bronchioles in response to various triggers, such as allergies or irritants. Mucus production is also increased, leading to the formation of mucus plugs that can further obstruct airflow. Asphyxia refers to a lack of oxygen supply to the body, while croup is a viral infection that affects the upper airway. Cystic fibrosis is a genetic disorder that primarily affects the lungs and digestive system, causing chronic respiratory infections and digestive problems. While it can also lead to bronchial obstruction, asthma is the most likely diagnosis based on the symptoms provided in the question.
