The frequency and degree of symptoms vary widely among asthmatics.  Some patients occasionally a moderate and brief crisis and have no obvious symptoms in the meantime. Others were almost always a slight cough and wheezing, with severe exacerbation of symptoms after exposure to known allergens, viral infections, exercise, or nonspecific irritants.

The asthma attack often begins acutely with paroxysms of wheezing, coughing hard and dry, and shortness of breath, or more gradually with symptoms of respiratory distress is slow. The patient experiences shortness of breath with rapid breathing, coughing, chest tightness, wheezing audibly. The crisis may fade rapidly or persist for several hours or days. Sputum expectorated mucus is viscous end crises. Read the rest of this entry »

The word asthma in Greek means to be breathless.
Responsible bronchial obstruction in asthma is the result of several changes that will reduce the size of the airways:
- Bronchial muscle contracts: the bronchoconstriction;
- The wall of the bronchus thickens: it is swelling;
- The inner wall of the bronchus (mucosa) secretes mucus important: it hypersecretion.
Edema and hypersecretion reflect a change in bronchial inflammation called bronchi.
This inflammation is often not felt by the patient but is nevertheless the depths of the disease that is evolving into asthma chronicity. Read the rest of this entry »

Bronchial asthma is a disease that causes a reversible paroxysmal bronchial obstruction. It is characterized by airway hyperresponsiveness to various stimuli.

Causes of disease Bronchial asthma

Bronchial asthma can be triggered by different stimuli.
- The extrinsic or allergic asthma is triggered by specific allergens (house dust, pollen and mold from the air, animal dander), symptoms are associated with immunoglobulin class IgE.
It occurs mainly in children and young subjects.
Occupational asthma is allergic asthma.
- Intrinsic asthma is not inflammatory or allergic. It is the inhalation of irritants (exhaust smells of fresh paint or other substances, cigarette smoke) and infections, sometimes even violent emotions, variations in atmospheric pressure or temperature, the Inhalation of cold air, triggering the crisis.
- Some medications can cause asthma (aspirin, anti-inflammatory drugs, beta blockers, etc..)
- Some angitis (vessel disease) may be proved by asthma.

In practice, these data are very theoretical factors for allergic and nonallergic are often linked.

About Asthma

Asthma is a respiratory illness that is manifested by periods during which the airways constrict. During a crisis, opening airways is reduced because of inflammation and contraction of the muscles of the bronchial wall. A crisis is often a dry cough, followed by difficulty breathing, which causes wheezing clearly audible.

Two periods of life seem more conducive to asthma: the childhood and early forties. People with asthma have an incentive to monitor their treatment and to adjust their lifestyles accordingly. Poorly controlled asthma symptoms can transform sporadic in permanent symptoms.

Symptoms

For some people, asthma is distinguished only by a persistent cough which often occurs at bedtime or after exercise.
