Asthma (AZ-ma) is a chronic (long-term) lung disease that swells and narrows the airways. Asthma causes recurring periods of wheezing (wheezing), tightness in the chest, shortness of breath, and coughing. Coughing often occurs during the night or at dawn.
Asthma affects people of all ages, but it most often begins in childhood. In the US, more than 25 million people suffer from asthma. About 7 million of them are children.

To understand asthma, it is helpful to know how the airways. The airways are tubes that carry air in and out of the lungs. People with asthma have inflamed airways. Inflammation makes the airways swollen and very sensitive. The airways tend to react strongly to certain inhalants.
When the airways react, the muscles tighten around them. This narrows the airway, causing less air to flow into the lungs. The swelling can also worsen, making even the narrow airways. The airway cells could produce more mucus than normal. The mucus is a sticky liquid, thick, which can further reduce the airway.
This chain reaction can lead to asthma symptoms. Symptoms may occur when the airways become inflamed.
What causes asthma?

The inner walls of the airways of asthmatics become swollen or inflamed. This swelling or inflammation makes the airways very sensitive to irritations and increases their susceptibility to allergic reactions.
As the inflammation causes the airways to narrow, less air can pass through them, both to and from the lungs. Symptoms of stenos include wheezing (a wheezing when breathing), tightness in the chest, trouble breathing, and coughing. Asthmatics often experience these symptoms more often at night and in the morning.
Asthma is incurable
Asthma is an incurable disease. However, with proper management and treatment, there is no reason why a person with asthma can not live a normal and active life.
What is an Asthma Episode / Attack?
An episode of asthma or an asthma attack is when the symptoms are worse than usual. They may appear suddenly and may be mild, moderate or severe.
What is happening during an asthma attack?
The muscles surrounding the airways contract, the narrowing of the airways.
Less air is able to flow through the airway.
Increases inflammation of the pathways, further reducing the airway.
More mucus is produced in the respiratory tract, which undermines much more air flow.
treatment
Prevention of symptoms is the best strategy. An asthmatic person should know what situations trigger an attack and avoid as much as possible. If asthma attacks are severe, unpredictable, or grow more than twice a week, consulting with an allergy specialist can help determine your cause and provide long-term treatment that controls or eliminates symptoms.
Asthma Facts
Studies show that people with asthma who see a specialist, such as an allergy specialist, reduce them:
symptom
Visit the emergency rooms
Stays in the hospital
Visits to the doctor because they are sick
Days lost from work or school
Cost of medical care
If asthma is left unworked or misdiagnosed, it can be deadly:
Asthma is one of the most common chronic diseases in childhood, accounting for 10 million school days lost per year. It also includes the 14 million lost workdays for adults.
Every year about 14 million Americans see a doctor for asthma. About 1.4 million patients visit an outpatient department of the asthma hospital; Nearly 1.75 million go to an emergency room of a hospital.
The number of people in the US With diagnosis of asthma is increasing. The highest increase in asthma rates among black children, with an increase of almost 50 percent from 2001.
Researchers estimate that costs associated with asthma, including direct costs of health care and indirect costs, such as reduced worker productivity, are around $ 60 billion per year.
Many asthmatics are managing the disease and can live a healthy and productive life by avoiding the triggers and following their allergists’ instructions. If left unmanaged or misdiagnosed, asthma can be fatal; about 3,300 people die from it annually.
