Bronchial asthma is a chronic inflammatory disease of the respiratory tract, characterized by partial and reversible obstruction of the respiratory tract (bronchi), attacks of coughing and choking, increased reactivity of the bronchi.
Asthma is one of the most common childhood illnesses. The causes of asthma can be very different. Asthma refers to diseases with a real lethal potential. This means that the patient's death can occur during one of the attacks of the disease (asthma attack) buy ventolin online. In this article we will consider the most common causes of asthma, as well as the general mechanisms of the development of this disease. Knowing the causes of the disease and the mechanisms of its development is a key factor in the organization of measures for the treatment and prevention of asthma in children and adults.
Bronchial asthma is a chronic inflammatory disease of the respiratory tract. In this case, asthma is characterized mainly by the defeat of the bronchi. Asthma significantly differs from diseases such as bronchitis or bronchiolitis, in the development of which the main role is played by the bacterial factor, that is, the infection that affects the respiratory tract. In bronchial asthma, the infectious factor plays a secondary role, and in the first place there is an increase in the reactivity of the bronchi, which is based on allergic mechanisms. In this case, the main manifestation of asthma is the narrowing of the respiratory tract (bronchi) during attacks of the disease. The mechanisms of the development of asthma and the causes of this disease are discussed in more detail below.
Asthma is one of the most common diseases of the respiratory system in children. In the US, the incidence of asthma in children is 5 to 12%, according to various sources, while boys are more likely to develop asthma in early childhood. In adolescents, asthma occurs with equal frequency in both boys and girls. Asthma is more often affected by urban residents (more than 7%), in rural areas the incidence of asthma is approximately equal to 5%.
Allergic or atopic dermatitis, or allergic diathesis - words that have firmly entered our life and are often perceived by us as everyday phenomena that simply need to be experienced. But who is to blame?
Sometimes it is not possible to "just survive" an allergy. Constantly red cheeks or other areas of the skin (wet or covered with crust, accompanied by severe itching) cause panic and horror of parents and grandmothers of "beloved children" in front of a problem that has already become a "disease of our time". Unfortunately, very often diathesis in a child is a huge number of all kinds of medications, a wide range of counselors and compulsory malnutrition (for some reason called hypoallergenic diet under the motto "nothing is impossible").
Why the overwhelming majority of patients in pediatricians are children with allergies? Why are the most common drugs in pharmacies - are they different antiallergic drugs? Why is the news that some child "poured out" we already perceive as something normal? After all, it was not so common 10-20 years ago? Eternal questions: "Who is to blame?" And "what to do?" So, who is to blame?
Bad ecology. Yes, indeed, in children living in areas where industrial and chemical enterprises are located, in areas with an unfavorable ecological background, in large cities, in houses with poor sanitary and environmental characteristics, allergy manifestations are more common. But is it really that the environmental situation has changed dramatically in the area of your residence in recent years? But not all the same 100% of the small inhabitants of your district are diagnosed with diathesis? But why should your child have allergic manifestations on the skin?
Bronchial asthma is a chronic disease of the respiratory tract. Attacks of suffocation, chronic coughing, wheezing with whistling breathing make up the main signs of asthma in adults.
Earlier definition of asthma is extremely important for timely treatment and prevention of exacerbation of the disease. Often recognize the signs of asthma in adults can be already at an early stage of the disease. The most pronounced symptoms of asthma in adults are during an asthma attack (asthmatic attack).
The term bronchial asthma originated from the word asthma. That from Greek means suffocation, not free breathing. From this it can be concluded that the name of the disease (asthma) originated from the name of the main symptoms of the disease.
The development of an asthmatic attack occurs in different ways and is determined by the individual characteristics of the patient's body. The circumstances under which an attack is formed are also very different. Atopic form of the disease attack can be caused by contact with the allergen. Attacks of infectious-allergic asthma can occur against a background of strong emotional stress, during a respiratory disease or spontaneously.
Often, the onset of an attack predicts the sudden appearance of a cold, itchy skin, sensations of constriction in the thoracic region. The attack usually begins suddenly: the patient feels a strong tightness in the chest, anxiety, difficulty breathing. In such conditions, patients with an asthmatic attack prefer to sit down, leaning their hands against the wall - this helps to connect the external muscles in the act of breathing.
Asthma can occur at any age and for medical reasons, signs of asthma in adult women are more common than in men.
Bronchial asthma is a respiratory disease that has a chronic form. Chronic coughing, attacks of suffocation, and a whistling of breath are the main signs of asthma in adults.
To prevent asthma exacerbation, it is extremely important to determine the disease in the early stages, this will allow us to start treatment in a timely manner. Recognize the disease at an early stage, as soon as the first pronounced symptoms of asthma, which eventually become an asthmatic attack.
The asthmatic attack develops in different ways, it all depends on the characteristics of the patient's body. Atopic form of the disease is characterized by seizures in contact with the allergen. With regards to infectious-allergic asthma, seizures occur against emotional overstrain, or with respiratory diseases, spontaneous seizures occur extremely rarely.
Most often, the onset of an attack predicts signs of asthma in adults with a manifestation of a cold, itching, a feeling of tightness in the chest. The attack itself can start suddenly: there is an alarm, breathing becomes difficult, there is a feeling of tightness in the chest. With such symptoms, the patient should sit comfortably and lean against the wall with his hands, this position helps the external muscles to connect the act of breathing.
If the suffocation increases, then dry wheezing occurs in the chest, which are audible to nearby people. The asthmatic begins to breathe hard and it is harder for him to breathe out than inhale. During an attack, the thorax dilates, and the cervical veins swell. This condition can last a long time, but after a while the patient's breathing begins to recover.
