Childhood Asthma: A concern for a better future

Asthma, a well-known long-term inflammatory disease of the airways of the lungs. Each year, many people with asthma require treatment in the emergency department with a portion requiring hospitalizations. Children younger than 18 years of age account for a large portion of emergency department visits and hospitalizations due to asthma exacerbations. The extent of the consequences of asthma in children can be demonstrated by the fact that asthma accounts for more hospitalizations in infants than any other incurable illness. Moreover, asthma induces adolescents and children to miss school and causes parents to miss work days. As might be anticipated, asthma also values for added school absences than any other chronic disease.

The disorder caused by the inflammation of the bronchi leading to the lungs is called Asthma. This inflammation causes bronchi to contract and narrow, which restricts air from circulating easily into the lungs, making it difficult to breathe. Symptoms include breathlessness, wheezing, cough, and chest tightness especially at night or after workout/activity. The inflammation may be totally or somewhat reversed with or without medications.
The infection of the bronchi makes them very twitchy, followed by the spasm of the airways that tend to narrow, especially when the lungs are imperilled to an abuse such as viral infection, cold air, allergens, exercise and exposure to smoke. The reduced calibre of the airways results in a reduction in the amount of air going into lungs, making it hard to breathe. When an individual with asthma is revealed to a trigger, their delicate bronchi become inflamed, expand up, and fill with mucus. In addition, the muscles lining the swollen airways contract and constrict, making them even more narrowed and obstructed.
So, an asthma flare is caused by three major developments in the bronchi that make inhaling more complex:
1.       Swelling of the Bronchi.
2.       Excess mucus that happens in obstruction and mucus "plugs" that get intercepted in the narrowed bronchi.
3.       Narrowed bronchi or bronchoconstriction.

Anyone can have asthma, including children and youths. The trend to evolve asthma is often inherited; in other words, asthma can be more prevalent in several generations.

More will be discussed in the upcoming “21st Global Summit on Pediatrics, Neonatology & Primary Care” which is being held on 16th and 17th July 2018 at Dubai, UAE.
