These signs can occur at night or during exercise, often interrupted by long periods of lull.
THE SYMPTOMS OF THE ASTHMA CRISIS
The best-known symptom of asthma is the seizure, which causes difficulty in inhaling and especially exhaling air from the lungs. These “bronchospasm” can be triggered by various factors such as stress, humidity, dust, cigarette smoke, pollen, etc. We can easily distinguish a hissing sound during exhalation, attesting to the narrowing of the bronchi. The air is then trapped in the chest, the chest blocked. By coughing, the body tries to reject the phlegm that accumulates in the bronchi.
The crisis can be explained by three phenomena:
Bronchial muscle contracts (bronchoconstriction);
The wall of the bronchus thickens (edema);
The inner wall secretes significant mucus (hypersecretion).
What is the cause of asthma?
There is a part of heredity. In fact, the risk of having asthma is greater if people in your family already have asthma. Other factors, including environmental factors play a role in the onset of asthma.
What are the factors that can trigger a crisis?

Signs suggestive of allergy: fold of the lower eyelid, folliculosis, edematous conjunctivitis, pale nasal mucosa, redness of the pharynx, otitis mucosa, dry skin, accentuation of the palmar folds etc.
The diagnosis of asthma is based on the clinical examination of the physician and the respiratory functional explorations (EFR) that will confirm the presence of the disease. “These non-invasive tests last about 20 minutes to assess the importance of respiratory function deficit, to investigate any associated functional abnormalities, to evaluate the reversibility of the obstruction and to monitor the evolution of the disease “
