Asthma Essay

overview of asthma. Tobacco smoke and environmental factor like carbon monoxide, sulfur dioxide, lead, hydrogen cyanide, ammonia, cold, ozone, temperature variation, humidity and nitrogen oxides are the leading cause of respiratory disorders. Smoke produce irritation in pulmonary tract and other harmful pollutants implement bad effects to lungs. Prevalence of respiratory disorders is increasing tremendously (300 million people) and in future the ratio is expected to be high. Asthma is one of the

nearly 26 million Americans is asthma. This total includes more than 7 million children. Asthma causes millions of lost school and work days every year and is the third leading cause of hospitalization among children. There is no cure for asthma, but the good news is that it can be managed and treated, allowing you to live a normal, healthy life ("Learn About Asthma", 2016). One out of ten children and one out of twenty adults are diagnosed with asthma (Bryan, 2004). Asthma is noted as one of the most

environmental triggers contribute to the pathogenesis of asthma, one of the most prevalent respiratory diseases in the world (Burney et al, 2015). Studies have found environmental, physical and allergic triggers lead to exacerbation of disease in suffering populations. Similarly, in the last decade, advances in genetic research has lead to studies linking variation within specific genes and a vulnerability to developing asthma. Understanding asthma associated triggers has the potential to contribute

Asthma Asthma is one of the most prevalent respiratory diseases. It is a chronic condition with recurring, exacerbations characterized by bronchial hyper-responsiveness and inflammation leading to airflow obstruction (Cabana, et al., 2014). Over time, the chronic inflammation may cause permanent damage to the airway (Wenzel, 2012). Asthma affects people of all ages but typically begins in childhood (Wenzel, 2012). This paper will explore the pathophysiological mechanisms of chronic asthma and

Pathophysiology Asthma is a disease of the lungs that can be influenced by different genes or alleles. When the epithelial or mucosal barrier is exposed to pollens, allergens, microbes or pollutants, these can stimulate the underlying antigen presenting cells (APC) which causes an immune response to occur.17 This can cause a cell influx into the airway that is primarily eosinophilic or neutrophilic. When the allergens present themselves, they can initiate a breakdown in the physical barriers,

that working out could bring on an asthma attack, but the asthma patients should exercise in asthma. Asthma makes it hard to breathe, so it’s not surprising that many people think it’s wise to skip physical activities that lead to being out of breath in order to avoid the constricting airflow of an asthma attack. But that also means missing out on the major benefits of exercise, including getting better control of asthma. In addition to helping improve your asthma control, the short- and long-term

As I jogged in early February, my chest tightened and I felt like each breath I took was more and more painful. It was happening, an asthma attack. The cold had made my breathing almost impossible and each step I took felt worse and worse. My asthma had always affected me since I was a child but now as an adult I felt like everywhere I went I had to carry around my Ventolin, which didn’t make me feel socially accepted. When others were running in the cold, I felt left behind, needing to rely on a

Asthma is a chronic disorder of the airways that is characterized by reversible airway obstruction, cellular infiltration, and airway inflammation. The response involves the interplay of genetic and environmental factors, as well as the activation of cells in the innate and adaptive immune systems.1 (Hall, S.C et al. 2016) The role of vitamin D in the pathogenesis of asthma has been the focus of several researches over the last 2 decades. Results from these studies have identified a link between

Introduction: Asthma comes from the Greek meaning of short of breath which the world has come to known as asthma which is shortness of breath. Henry Hyde Salter was the first person to describe asthma in which he stated: “airways narrow due to contraction of their smooth muscle.” William Osler known as the father of medicine described asthma as a “spasm of the bronchial muscles, swelling of the bronchial mucous membrane, the special form of inflammation of the smaller bronchioles, similar to hay

Natural Remedies There are over 300 million people in the world who suffer from asthma. The inflammatory disease of the airways affects both young and old and there is currently no cure for the illness. However, this doesn’t mean symptoms cannot be alleviated and managed in many different ways. If you’re suffering from asthma, you have hope. Research has not yet been able to determine the exact causes for asthma. In an asthma attack the airways to long overacts to allergens or other irritants and become
