Bronchial asthma

Bronchial asthma

Bronchial asthma is a chronic lung disease in which the patency of the bronchi is affected. This in turn causes symptoms such as coughing, shortness of breath, tightness in the chest, and choking. Sometimes it helps to get rid of them:

So what happens to the bronchi during an asthma attack?

In healthy bronchi, the

lumen is clear and allows inhaled and exhaled air to pass through the airways unimpeded. Due to the development of inflammation, the bronchial walls swell, it thickens, at the same time bronchial muscle fibers shrink with the development of bronchospasm. In the spasmed bronchi the

re is an accumulation of mucus which disturbs the free passage of air flows, there is a feeling of lack of air, shortness of breath, wheezing.

Unfortunately, to date, it is impossible to give a definite answer to the question of what triggers the development of the disease. However, we can note some points that play an important role in the development of the disease. The main ones are genetic factor, environmental factors (polluted air, tobacco smoke, house dust, pollen, viruses and other agents which getting into lungs with air flow affect the active zones – receptors located in different parts of bronchi). It is important to know this, because different agents act on different parts of the bronchi and on what part of the bronchi an aggressive factor acts, depends on what medicine should be used to avoid an attack of bronchial asthma or to stop it quickly if it develops.

It is important to understand that this disease is chronic and you will have to be treated for the rest of your life.

Asthma and allergies.

Choking attacks can occur when you are hypersensitive to 1) components of house dust. The components of house dust include: – various fibers (clothes, bedding, furniture); – dust particles of books, magazines (library dust); – sloughed particles of the surface layers of skin (epidermis) of humans and animals (cats, dogs, rodents), animal dander, bird feathers; – spores of microscopic mold and yeast fungi; – particles of chitinous shell and products of vital activity of house dust mites and cockroaches. 2) pollen allergens of wind-dusted plants. To be able to cause an allergic reaction, plant pollen must have certain properties:

it must be pollen of wind-dusted plants;

The particles must be volatile;


The pollen must be in the air in considerable quantity;

pollen particle size should not exceed 35 μm.
There are three main periods of allergenic plant blooms for the average strip of Russia:

spring (April-May)-associated with the flowering of trees (birch, alder, hazel, oak, etc.);

early summer (June-mid July) – associated with flowering of cereals and meadow grasses (timothy, fescue, hedgehog, ryegrass, brome, rye, bluegrass, etc.);

late summer-autumn (mid-July-September) – associated with flowering of complex flowers (sunflower, wormwood, ragweed) and marsh grasses (lambsquarter).

In the presence of allergy to pollen of allergic plants or spores of mold fungi, cross-reactions to foodstuffs are often noted. This is due to the similar structure of the plant pollen allergen and the specific product.
