Asthma is a lung disease with the following characteristics:
- Airway obstruction fully or partially reversible, either spontaneously or with treatment.
- Bronchial inflammation and remodeling (fibrosis) of the architecture of the bronchus with mucosal infiltration by eosinophils and other cells, and a greater or lesser degree of permanent subepithelial fibrosis, even in the absence of symptoms.
- Bronchial hyperreactivity or increased response of the airway against different stimuli, nonspecific worst disease.
Given these characteristics, inflammation of the bronchial mucosa should always be to make a diagnosis of asthma, others may go through periods of varying activity and presence.
SYMPTOMS
Upon this inflammation of the bronchial mucosa are the following:
* Cough
* Wheezing
* Secretions (phlegm)
* Shortness of breath or fatigue
These symptoms usually follows in crisis, symptoms lasting a few days and giving, or present with symptoms steadily more intense with occasional flare ups. Atypically, there may be only a persistent cough, chest tightness with no other accompanying symptoms, or be hidden as recurrent bronchitis in children, being only a process of cough and phlegm, breathing without effort. In all forms is characteristic nocturnal predominance of symptoms.
