Today asthma is one of the most common diseases affecting people all over the world and within all age groups. There are over 300 million people who suffer from some type of asthma. In the U.S. there are approximately 20 million people who suffer from asthma. Asthma is more common among children with 1 in 20 children experiencing asthmatic symptoms. The word “asthma” is derived from the Greek word for “panting” (Izenberg 91). It describes what happens physiologically in the bronchi of the lungs during an asthmatic attack. During an attack the person suffers from inflammation of the bronchi lining, contraction of the muscles surrounding the airways (bronchoconstriction), and the increased production of mucus within the bronchi. The average asthma attack can last up to three minutes, but some symptoms persist longer. There is a wide range of symptoms that a person experiences during an asthma attack. Generally, there is difficulty breathing, wheezing during exhalation, coughing, and possibly mild anxiety. Bronchoconstriction of the airways causes the wheezing and coughing. Other symptoms can include tightness in the chest, difficulty speaking, exhaustion, and in some cases, hypoxia can develop. Asthma can also be associated with eczema and nasal polyps. Depending on the intensity and frequency of the symptoms, asthma is categorized based upon four levels of severity. The lowest severity type is mild intermittent asthma in which symptoms occur less than twice a week with attacks rarely happening. The second level is mild persistent asthma which means that the symptoms occur more than twice a week but not daily. Moderate persistent asthma involves daily symptoms with nighttime problems occurring more than once a week. This is the level in which the asthma affects the person’s daily life and requires the person to use medication every day to control the symptoms. The final level is severe persistent asthma which is characterized by frequent daily and nightly symptoms, persistent attacks, and a limited daily life. There are several different categories of asthma which are defined by what triggers the attack. These triggers can also be described as activators. Activators are not the cause of an attack; instead, they “ignite a chain reaction of events that lead to an attack” (Sander). Some people suffer from asthma triggered by allergens such as dust mites, pet dander, medications (aspirin), mold, and pollen. There is a probable genetic component with this type of asthma in families of asthma sufferers (www.asthma.com). Allergic asthma attacks can also be seasonal, especially during the spring and fall, and be activated by wind, rain, or even cold air. Non-allergic asthma sufferers react to air-borne substances such as smoke, perfumes, cleaning sprays, paint fumes, and room deodorizers. Emotions, such as laughing or crying, can also help trigger attacks in children. Other asthmatics experienced symptoms at night (nocturnal asthma). These people may shown signs of an attack sometime between 2am and 4am. This may be due to the fact that the body’s natural levels of adrenaline and corticosteroids are lowest during this time. Adrenaline and corticosteroids help in decreasing inflammation which in turn leads to a decreased likelihood of an attack. Another type of asthma involves the workplace. Occupational asthma occurs when a person is exposed to chemicals, fumes, gases, dust, or animal proteins. Symptoms can arise after a short exposure time, especially if the person already suffers from asthma, or over an extended time period. Some people have been known to experience attacks long after they are no longer exposed to the irritant. Finally, the last type of asthma is exercise-related asthma. Aerobic exercises (walking, running, using a treadmill) can lead to an attack with symptoms of chest tightness, coughing and wheezing, and an increased heartbeat five to ten minutes after the exercise. Asthma was first recognized as a disease…

Do you know somebody with asthma? Well, nine times out of ten you. Me, myself, I was born with asthma so I can relate in some many ways to this topic. Asthma affects many Americans each and every day and it’s becoming more common in humans as the years past. I’m hear to spread awareness about asthma and to give you a little more insight on the topic.
Asthma is caused by inflammation in the airways. When an asthma…
In the Unites States, asthma has become more prevalent in children than in adults according to statistics. In 2006, 6.8 million children under the age of eighteen had asthma, 4.1 million of which had an asthma attack, and many had hidden or undiagnosed asthma. Asthma is a common chronic inflammatory condition of the respiratory system in which the airways constrict due to episodes of airway obstruction. This inflammation causes the normal function of the airways to become excessive and over reactive…
Nine people die every day in America from asthma. Asthma is a respiratory condition, which is usually triggered by an allergic reaction, respiratory infection, strong emotions, stress, and many other environmental factors.
During an asthma attack the muscles around your airways tighten. This is called a bronchospasm. When the muscles tighten inflammation and mucus production are also heightened. This makes breathing difficult and in extreme conditions hypoxemia can occur.
Asthma is caused by a hyperactive airway disease, is a recurrent inflammatory disease of the airway. In individuals with asthma, the airway periodically spasm and narrow (a process called bronchoconstriction) in response to certain trigger. Then makes breathing difficult, and the individual may wheeze, cough, and gasp for air. The airways relax and widen either spontaneously or in response to drug treatment (Perspective on Diseases and Diseases and Disorders, Asthma, Pg17).
In asthma, normal breathing gets disrupted, which is ascribed as obstruction of the lungs. Owing to this, malady is also referred to as obstructive airway disease (OAD). The condition responsible for triggering asthma is hyper responsive reaction to a certain stimuli, known as allergens.
Asthmatics experience signs like tightness in chest, difficulty while breathing and wheezing. There is no definite cure for the malady, because of which reducing severity of attacks is considered the solution…
a) Asthma affects about 24.6 million people in the United States alone.
b) I think that people should be aware of asthma because it can actually be caused by smoking around younger kids and most people are diagnosed with asthma at a young age.
c) I think I am qualified to share this information because my brother, who is 5 years old, has had asthma since he was about 3 years old and I've gained the knowledge throughout the years to help him know what going on…

I was born with asthma. I have a severe case of asthma. Asthma has affected my life in so many ways. Three ways that asthma has effect my life is I can’t breathe normally around strong perfumes or scents. I get short of breath playing soccer, and I have a lot of asthma attacks.
During the day, it will get hard to breath and so I have to use my inhaler. But there are also so many things…
During the first week of 5th grade we learned about all the different clubs and teams my school offered. I was drawn to cross country. What kid wouldn’t love running around with his or her friends? I went home that night and had my parents sign all the papers for me to join the team. Everyone made the team so there was no need for tryouts. First day of practice was lame as usual; they just go over all the paperwork and the schedule…
Asthma is one of the most common chronic diseases through the world and is a serious global health problem that affects people of all ages. Asthma is a chronic inflammatory lung condition that is characterized by recurrent breathing difficulties due to the airways to constrict and produce excess mucus. This condition is reversible, either spontaneously or can be controlled with treatment such as medication. Based on gingivitis disease process, we know that in order to have tissue response, such as…
1. Discuss the pathophysiology of asthma.
The pathophysiology of Asthma includes inflammation of the airway. The way in which this works is from an irritant which can include dust, pollen, cedar, or cat hair. When a reaction occurs, the airways become inflamed and narrow. The narrowing occurs because once the inflammatory response is triggered by an irritant, histamines, immunoglobulin E antibodies, and leukotrienes are released. Because of this, mucous production occurs. Since the bronchioles are…
