Asthma is one of the most chronic diseases in children. According to the National Center of Health Statistics, the 1 of 7 children with asthma. Although it is unclear why the incidence of asthma is increasing. Some say it may result from climate change, increased influence allergies, or even inadequate exposure to childhood diseases that in the past would prepare the immune system to fight off the offenders better.
According to the National Institute of Health, boys are more likely than girls to get asthma than girls are more likely than boys to have asthma and adults. Up to 75% of children with asthma will outgrow it in adolescence. In many other children have symptoms as severe as they grow older.
How lungs work?
baby breathes air through the nose or mouth. The air moves from the trachea into the trachea, which is the wind pipe leading to the lungs, where it divides into branches called bronchi. Bronchi divide further into bronchioles that end in the alveoli (sacs surrounded by blood vessels). In the alveoli, oxygen exchange takes place. Oxygen that is breathed in enters the bloodstream and gets spread through the blood to all organs. On the other hand, carbon dioxide passes from the blood stream in the lung and gets inhaled.
What happens in the lungs of asthma?
Asthma is a chronic inflammatory disease of the condition of the lungs. Inflammation within the bronchioles causes inflammation of the airways that limits the air flow to the lungs. In addition, mucus is produced inside the respiratory tract, creating mucous plug that partially blocks the muscles that line the airways may constrict, thereby restricting the air flow further. These reversible inflammatory changes in the lungs lead cough at night, as well as coughing, running out of breath, or wheezing with crying, laughing, and movement.
The inflammation of the airways makes them vulnerable, resulting in seizures, which can be brought on by a variety of triggers. The most common triggers are allergens, smoke, pollution, exercise, cold weather, humidity and respiratory illness.
What is asthma?
Many children with asthma have no daily symptoms. They have symptoms only when they have to turn. These asthma flare-ups can occur suddenly and be severe. Other children have daily symptoms that require daily medication that keeps inflammation of the airways under control.
If a child constantly starts coughing, running out of breath, complains of chest tightness, or wheezes after coming in contact with pets, after or during exercise, or when he / she goes out when it is cold, these symptoms suggest asthma. A child with asthma might cough at night when it is sick, he or she may cough, run out of breath, or wheezing with crying, laughing, or exercise.
How is asthma treated?
Identifying asthma triggers makes eliminate or reduce exposure to known triggers, thereby reducing the frequency and severity of symptoms. All children with asthma should have bronchodialotor available to them at all times, to rescue in an inhaler or nebulizer that turns bronchospasm, airway obstruction due to muscle spasms brought on by turn. Since bronchospasm may occur suddenly and unexpectedly, a bronchodialator could be life saving.
Children receiving daily asthma symptoms to see an allergist to identify the allergic triggers their symptoms. They may need daily anti-inflammatory drugs to keep the lungs healthy.
