According to Peter Barnes, "Asthma is one of the most common chronic diseases globally and currently affects approximately 300 million people worldwide." Asthma is a disease that affects the respiratory system. It disturbs breathing tubes attached to the lungs; its function is to transmit air to and out of the lungs. It is really common that it is now considered as a severe public health problem (S. Hasan Arshad, K. Sureesh Babu, 2008). An asthma attack can cause coughing and wheezing. The patient's chest possibly will feel tight, and will most likely feel short of breath. The airways tighten and become narrower when something triggers an asthma attack, and the lining of the airways swells. Sticky mucus can build up making the airways even narrower. This makes it really difficult to breathe (Ballard, 2011). Things like allergens, cold air, exercises, emotions or medications can trigger asthma.
Allergies play an important role in many patients as a trigger, especially for children. Breathing in an allergen such as dust mites, animal dander, plan pollen, and mold spores can set ...
An asthma attack has many effects on the body. Asthma affects the body by limiting the flow of air into the lungs. It causes airway inflammation, bronchial restriction and irregular airway obstruction. Airway inflammation is how the body reacts to something that is irritating the airways. When happening your lungs begin swelling, your breathing passageway becomes restricted and mucus is secreted. Bronchial restriction happens when the muscles in your airways tighten around the breathing tubes in your lungs. (Bronchial tubes). Mucus or fluid that is accumulated by the reaction can obstruct your airway and make it very difficult to breathe properly.
Asthma is a disorder that interferes with the lungs and the airways to the lungs. It causes attacks of wheezing and difficult breathing. An asthma attack occurs when the airways respond to some kind of trigger, Some examples of triggers for Asthma attacks are dust, mold, pets, exercise, cold weather, and some attacks start for no known reason. The triggers may irritate the airways to the lungs, allowing disease-fighting cells to build up and causing the lungs to swell up. In addition, the airways could get blocked when the muscles surrounding the lungs tighten. This keeps air from circulating freely in the lungs. Or, mucus may clog and narrow the airways in the lungs, making breathing even more difficult.
Asthma itself is an inflammatory disease characterized by increased airway responsiveness due to a variety of stimulus. The inflammation causes the hyper-responsiveness than in turn causes bronchiolar smooth muscle constriction, resulting in obstruction of airflow. Some “triggers” of asthma include:
Asthma is a condition of the bronchial tubes characterized by episodes of constriction and increased mucous production. A person with asthma has bronchial tubes that are super sensitive to various stimuli, or triggers, that can produce asthma symptom.In other words, asthmatics have special sensitivity that causes their lung tissue to react far more than is should to various stimulating factors or triggers. For this reason, people with asthma are said to have "twitchy airways."Some symptoms that people with asthma commonly experience are chest tightenings, difficulty inhaling and exhaling, wheezing, production of large amounts of mucous in their windpipes and coughing.Coughing can be frequent or intermittent, and can be loose-reflecting extra mucous secretion in the airways or dry and deep-reflecting tight bronchospasms. Not all these symptoms occur in every case of asthma.Sometimes people may have coughing without and symptoms for months or even years before it's realized that they are asthmatic. Interestingly enough, asthma symptoms are most severe at night, while we're lying down our airways narrow as a result of gravity changes. Also our lungs do not clear secretions as well at night, which leads to mucous retention, and that can increase the obstruction to air flow.
Secondly, severe asthma can be life-threatening. Suffering from asthma can be frightening to experience and people often feel scared and anxious. The fear and scare can also lead to breathlessness and so mak...
Asthma is chronic inflammatory disorder of the airways characterized by recurring episodes of wheeling and breathlessness. It often exists with allergies and can be worsened through exposure to allergens. In fact, asthma is complicated syndromes that have neither single definition nor complete explanation to the point. In light of its treatment, it is worthwhile to notice that asthma cannot be cured, instead can be only managed by avoiding exposure to allergens and/or by using medications regularly.
When people hear the word asthma, the first thing that comes to mind is a nerd wheezing and taking an inhaler almost every five minutes, but that is not the case for everyone who is diagnosed with this disease. A person with asthma will often wheeze, become breathless, experience tightness in the chest, and cough at night or early in the morning. Asthma is a chronic respiratory condition and a disease marked by spasms in the bronchi of the lungs, caused by chronic inflammation within the breathing passages. This may...
The respiratory system works in a way that organs in the body are responsible for taking in oxygen and expelling carbon dioxide. One major organ is the lungs; it carries out the exchange of gas as we breathe. During the process of breathing, the mechanism can be obstructed in different ways and that can result in inflammation of the lungs. Different diseases are being generated due to inflammation of the lungs but my case study is on Asthma. Based on the summary of Urata Yoshida, “Asthma is a disease that involves inflammation of the lungs which directly affects the airway and obstructs airflow in and out of the lungs”. (Respir Med. 2002). Majority of the time, asthma starts at a young age more like my case study about 17 years old girl called
From 2001 to 2010, asthma prevalence rose from 7.3% to 8.4%, reveling just a little over a 1% percent growth in nine years (Trends in Asthma Prevalence, Health Care Use, and Mortality in the United States, 2001-2010, 2012). This does not appear as an enormous increase until we look at that 1%, as the millions of people affected yearly. In 2009, there was a reported growth of 4.7 million new asthma diagnoses. In 2010 reports showed that there was 10.5 million physician office visits and 1.8 million emergency department visits, responsible for 439,000 hospitalizations and 3,630 deaths (Evidence Summary: Control Asthma,
Imagine you are out to lunch one day with your son and someone lights up a cigarette. All of a sudden you notice that your child is not breathing properly, he begins to wheeze, and tells you that he feels like he cannot breathe, and his chest feels tight. You and your son are rush to the nearest emergency, where the doctors discovers that your son has just had an asthma attack triggered by the cigarette smoke. Asthma is condition that affects the lungs. The airways of the lungs swell and the muscles in surrounding airways tighten, leading to a decrease of the flow of air that is able to get to the lungs. Signs and symptoms of asthma include but are not limited to: shortness of breath, tightening of the chest, wheezing, and coughing. Asthma is lifelong condition that can be treated a controlled through a variety of ways. One way to treat an asthma attack with an inhaled cortical steroid, this is a long term treatment. Other forms of long term treatment are long-acting bronchodilators, Leukortriene inhibitors, and Cromolyn sodium. In a national survey conducted in 2012 states that 14% or approximately 10 million U.S children have been diagnosed with asthma. According to an article published by the Center for Disease Control and Prevention, asthma is the leading chronic illness among
A person who experiences perpetual shortness of breath or hears a whistle-like sound in their chest when they breathe, is more than likely to have asthma. Asthma is a chronic disease/condition in which the airways in a person’s body are inflamed and produce extra mucus, which makes breathing troublesome. In addition, the bronchial tubes, passageways that allow air to enter the lungs and come back out, are narrowed, which makes it even more difficult to breathe. Breathing is essential for humans to survive and carries out important functions in our bodies. This disease is very common in the United States, about 1 in 12 people (about 25 million) have asthma, and the numbers are increasing every year.
Asthma is best described by its technical name: Reversible Obstructive Airway Disease (ROAD). In other words, asthma is a condition in which the airways of the lungs become either narrowed or blocked. The results are usually temporary but they cause shortness of breath, breathing trouble, wheezing, coughing, and tightness in the chest. To know what it really feels like to have asthma, I would like everyone to pick up the straw that’s on their desk and put it in their mouth as if they were using it to drink something. Then, pinch your nose. Try breathing for twenty seconds. A real attack can last up to more than 10 minutes and you are only doing it for 20 seconds. If we had more time, I would have the class go to a stairwell and have you run up and down and see what it is like to have asthma while doing other activities.
Breathing is a vital process for every human. Normal breathing is practically effortless for most people, but those with asthma face a great challenge. During an asthma attack, breathing is hampered, making it difficult or even impossible for air to flow through the lungs. Asthma is an increasingly common problem, and has become the most common chronic childhood disease. At least 17 million Americans suffer from it(1), and although it can be fatal, it is usually not that severe(4). There is no cure for asthma, but with proper care, it can usually be controlled.
Allergic asthma. Asthma is characterized by airway inflammation, goblet cell hyperplasia with mucus secretion, increased IgE, airway hyper-responsiveness and airway remodeling. Asthma is a multi-factorial disease with strong genetic and environmental components (33-35). In the 2004 report from the Global Initiative for Asthma Worldwide, it was estimated that ~300 million people suffer from asthma (36). From 2001 - 2003 an average of 20 million people suffered annually from asthma the United States (2). Asthma affects all demographic groups but can disproportionately impact people based on age, sex, ethnicity, obesity and socioeconomic status and is increasing in prevalence in the United States and World-Wide
The most triggers in the home are caused by mold from ongoing leaks in the apt. Air vents that have been emitting dust particles from roofs. Dust particles coming in from outside construction or traffic. Roach infestations, lead, and fecal matter or dead roach carcasses filling the air. Mice and rodents are other sources of problems when it comes to uninhabitable living conditions. Vermin tend to drop the fecal matter and urinate all over their environment this causes asthmatics more problems with breathing. Most people living in New York City housing live in apartments that are deteriorating infrastructures that are roach and rodent infested due to lack of
