Asthma. Symptoms and Causes

Definition of asthma
Asthma is defined as a disease characterized by attacks of varying duration expiratory dyspnea, cough, wheezing and a feeling of constriction due to spasm of the bronchi. It is produced by various causes in many cases the mechanism is immunoallergic.

As repeated attacks, the disease causes severe and persistent disorders of the respiratory system first and then cardio-circulatory.

Pathogenetic mechanism of bronchial asthma
Although there are cases of asthma that can not be associated with allergies, has observed that in most cases you can prove the origin of bronchial asthma are allergic to the discovery of the substance causing the sensitization (allergen).

The attack of bronchial asthma
As discussed in our article on types and symptoms of allergies, bronchial asthma attack is caused due to a more or less abundant discharge of histamine from the tissues in a state of hypersensitivity and allergic shock due to the "antigen - antibody.

Moreover, it has been shown that histamine has the ability to contract spasmodically all the smooth muscles of internal organs and, therefore, of the bronchial walls. Because of this, during an asthma attack, bronchial smooth muscles arranged in rings along the bronchial walls tighten sharply, reducing the internal size of bronchi by circulating the air in respiration. This causes bronchospasm more or less pronounced difficulty in breathing so characteristic of the asthmatic attack.

Outline of bronchial asthma attack
* Meeting antigen-antibody in tissue and blood
* Release of histamine.
* Spasm of bronchial rings by the action of histamine.
* Contraction of bronchial rings.
* Reducing the size of the bronchial rings
* Reduction of the air inlet to the bronchi.

On the other hand, has shown that respiratory distress of asthma attack is not only due to bronchial muscle contraction but blood congestion of the bronchial mucosa further reducing the caliber of the bronchial rings.

Causes of bronchial asthma attack
One can distinguish between the causes of asthma attacks following causes:
* Causes determinants
* Predisposing causes
* Causes triggers

Determinants. If we understand that behind the attacks is a component of allergic asthma, allergens that sensitize the body are the determinants. Among these are:

* The pollen of flowers, grass species (hay fever).
* Various powder rooms, cities, barns, factories, etc..
* Herbal substances: seeds and cereal flours, leaves, roots, bark, etc..
* Medicines: aspirin, antibiotics, barbiturates.
* Animal Hairs
* Different kinds of molds.
* Food: eggs, milk, seafood, fruits, vegetables, etc..
* Other causes.

Predisposing causes. We speak of predisposing causes because it is clear that not all suffering from bronchial asthma due to allergens. This means they are only a few individuals who are constitutionally predisposed to become sensitized to substances that previously quoted.

However, it should be borne in mind that the disease is not inherited, but the constitutional predisposition to get sick. That is, not born asthmatic, but the person gets asthma when he inherited predisposition to the disease constitutional. Needless to become asthmatic contact with the substance triggering the attack.

The profession may be another predisposing cause due to continued exposure to allergens trigger asthma attacks. For example, flower growers, weavers, millers, farmers, etc.., Etc.

The season of the year as in the case of hay fever is another predisposing factor for many people due to pollen from flowers that appear in the spring months.

Even age can be included among the predisposing causes as age between 30 and 40 years is presented in a large number of cases of bronchial asthma.

Precipitating causes. Are those that influence the state to trigger an allergic asthma attack. For example, emotions, psychological factors, digestive disorders, fog, sudden variations in temperature, humidity, pressure, wind etc. etc.

Symptoms of bronchial asthma
Most asthma patients have suffered for months or years respiratory light when contacted with the substance that causes allergic sensitization slowly.

Symptoms before the onset of asthma
In this case the patient may feel certain their experience warning symptoms such as:

* Loss of smell, nasal congestion.
* Irritating dry cough.
* Difficulty breathing deeply,
* Flatulence,
* Humor restless.
* Urticaria.

Symptoms during an asthma attack
* Feeling of suffocation or air hunger "
* Feeling of dying from asphyxiation.
* Open the window for air to think that lack air in the room.
* Cold sweat.
* Boca ajar.
* Of the expiration respiratory phases is prolonged, stops and makes painful.
* Fast pulse.
* Usually no fever.

Childhood Asthma Symptoms
The form of childhood asthma produces severe symptoms:
* Fever
* Dyspnea almost suffocating
* Bluish skin.

When a high fever with pulmonary symptoms wealth can lead to the diagnosis of bronchopneumonia.

Usually childhood asthma disappears spontaneously at puberty.
