To better understand the impact of asthma, a brief overview of the causes (aetiology) and disease progression (pathophysiology) must be shown. As common as asthma is, not much is known about its aetiology, according to findings presented by Subbaroa, Mandhane and Sears (2009, pg. 181-187) in a review from the Canadian
Asthma is a long-term lung disease. Those with asthma have sensitive airways in their lungs which triggers a flare up. When this flare up happens the muscle around the airways squeeze tight and the airways swell, become narrows and produce more mucus. (Anon., 2016) All these things make it harder for a person to breathe. Asthma effects the human body’s respiratory system. Asthma causes a spasm and constriction of the bronchial passages and the swelling and the inflammation of the mucous lining. The body responds by defence cells from the immune system, which causes the airways to swell and the muscles surrounding the airways to contract. Which is what cuts off the airflow. While a person is in asthma attack, the asthmatic cannot breathe which
Inflammation of the airways is an important component of asthma. Inflammation can make your airways more sensitive and more narrow than usual, making it harder to breathe. The airways in the lungs may react to various triggers and become more inflamed. The muscles around the airways can also tighten. All these can reduce airflow in your airways and can cause asthma symptoms.
Asthma Attack – An asthma attack is a sudden worsening of asthma symptoms caused by the tightening of muscles around the airways. During an asthma attack, the lining of the airways also become swollen or inflamed and thicker mucus, more than normal, is produced. All of these factors, cause symptoms of an asthma attack such as difficulty breathing,
Asthma Misty Kroenke November 29, 2010 HCS245 Timothy Coleman Asthma is a widespread disease that affects many cultures and has no boundaries. It does not care about country, race, religion or sex. Asthma can affect anyone and can develop at an early age or later in life. People who have asthma the airways in the lungs narrow and swell. They produce extra mucus and breathing becomes difficult. Some common signs and symptoms of asthma are coughing, wheezing and shortness of breath. Asthma is a common long term disease of children, but some adults have asthma too.
Asthma is a respiratory disease that many people deal with every single day. “According to World Health Organization, approximately 180,000 people die from asthma each year.” (Jardins and Burton 187) Most people never think of asthma as a life threatening disease, but it can be crucial. As the number of
Based on Ignatavicius and Workman, asthma is usually a chronic condition that causes obstruction. The pathophysiology behind asthma, is the hypersensitivity of the tissue in the lungs. When a trigger comes in to the lungs, the airway overreacts to it, and causes excessive swelling and mucous productions, which constrict the airway and makes it difficult for the individual to breath (2016). There are different types of trigger that can initiate an asthma attacks, and it also varies per individuals. Some of the triggers are allergens, dust mites, outdoor air
The effect of asthma can range from mild, irregular symptoms causing minor problems for an individual to severe and sudden asthma attacks. The extent of what causes asthma is not well known or fully understood but some common triggers include, cold temperatures, dust mites, cockroaches, pollen, sickness, mould and animal hair. When triggered, the airways in the lungs become inflamed and constricted causing shortness of breath, chest pain and wheezing [R]. Currently, there is no cure for asthma however symptoms can be managed with medication and improved living standards [R]. Asthma symptoms are commonly controlled with the use of inhalers, either preventers (taken to desensitizes airways to triggers) or relievers (provides instant relief by relaxing the muscles) .
Asthma is a disease that affects your lungs. It causes repeated episodes of wheezing, breathlessness, chest tightness, and nighttime or early morning coughing. Asthma can be controlled by taking medicine and avoiding the triggers that can cause an attack. You must also remove the triggers in your environment that can make your asthma worse.
Asthma itself can be described as having 3 major features: airway obstruction, Hay fever is the single most common chronic allergic disease. This is the most common trigger for someone with asthma and allergies to get symptoms. Exercise-induced asthma-This is caused by exercise or physical exertion. With exercise-induced asthma, airway narrowing peaks 5-20 minutes after exercise begins. An asthma inhaler will help to prevent these uncomfortable asthma symptoms. Cough-variant asthma-With this type of asthma, severe coughing is the predominant symptom. Cough-variant asthma is vastly underdiagnosed and undertreated. The main triggers for this type are usually respiratory infections and exercise. Occupational asthma-This results from only workplace triggers. Many people will suffer with a runny nose, congestion, eye irritation, or have a cough instead of wheezing. Some jobs associated with this type of asthma are animal breeders, farmers, hairdressers, nurses, and painters. Nighttime asthma-If you have asthma, the chances of you having symptoms are much higher during sleep because asthma is powerfully influenced by the sleep-wake cycle. So your asthma symptoms are particularly dangerous at nighttime (WEBMD).
Asthma is a serious condition that involves the chronic inflammation of your airway, and can partially or completely inhibit your ability to breathe properly. It was most recently reported that around 8% of the American population has asthma, and this condition is only becoming more common.
Soaring Rates of Childhood Asthma Asthma affects people of all ages, but it most often starts during childhood. Asthma is a chronic lung disease that inflames and narrows the airways, which are tubes that carry air into and out of your lungs allowing one to take in oxygen and breathe out carbon dioxide. The swelling also can worsen, making the airways even narrower and the ability to breathe more difficult. Sometimes asthma symptoms are mild and go away on their own or after minimal treatment with asthma medicine, but other times symptoms continue to get worse. When symptoms get more intense and more symptoms occur, you 're having what is commonly known as an asthma attack. During an asthma attack you are in complete panic and the swelling in your airways reaches a point where it is no possible to take air into the lungs. If action is not taken to reduce the swelling of the airways in order to restore breathing, someone could die of asphyxiation, or the lack of oxygen. The number of people being diagnosed with asthma is on the rise, especially in the rates of children developing symptoms of asthma at a young age.
As the world population grows, so does the amount of people in this world with Asthma. “In the last decade, the proportion of people with Asthma in the USA grew nearly 15%, with 479,300 hospitalizations and 1.9 million emergency department visits in 2009 alone”(Kaur, Bani Preet). Asthma affects the bronchi,
Asthma is a lung disease characterized by variable and reversible airway obstruction, airway inflammation, and bronchial hyper-responsiveness. Causes recurring periods of wheezing, shortness of breath, chest tightness, and coughing; coughing normally occurs at night or early morning. Asthma affects people of all ages and mostly starts in childhood. In the United States, more than twenty-five million people are diagnosed with asthma and about seven million of these people are children.
Review of Related Literature and Critical Appraisal Asthma is a chronic airway disease that can be difficult to manage, resulting in poor outcomes and high costs (Kuhn et al., 2015). It is characterized by episodes of expiratory airflow obstruction, which occurs in response to multiple stimuli or triggers. Asthma is a
