Free Essay on Asthma

Free example essay on Asthma:

For some, the agony of asthma may be an affliction only during childhood; for others, the illness persists throughout adulthood.

In an asthmatic attack the diameter of the small bronchi is diminished as a result of spasm of the muscular coat, active congestion of the mucous membrane and excessive secretion of tough mucus. In inspiration the small bronchi are pulled open and the obstruction is thereby reduced. On the other hand, forced expiration tends to compress bronchi and increase the obstruction. Consequently inspiration is much easier than expiration; the difficult breathing of asthma differs in fact from all other forms of difficult breathing, in being mainly expiratory in character (Mezei, 1988). The asthma victim, however, usually hypersensitive, overreacts with severe symptoms (Renard, 1996).

Asthma deaths in the country are steadily rising at an ever-increasing rate. Statistics indicated that about 4,000 Americans died from the disease in 1985, more than double the number only a decade ago. Society became more involved into the process of ┬ádetermining why asthma death were increasing. A task force of immunology, chemistry, pulmonary medicine, and epidemiological researchers were charged with finding an answer, but their preliminary report only raised more questions. But while the severity of the disease appears to be increasing, many asthmatics are unwilling to lead the sedentary lives that some say their condition requires (“Asthmatics”, 19XX).

As seen in many studies and research done in the past exercise can be both beneficial and deleterious to an asthma patient. New research showed that a health and fitness program called, The Eagle’s Circle improved flexibility, strength, aerobic fitness and quality of life for children with asthma involved in the program. Although children with asthma often avoid physical activity for fear that it will trigger an asthma attack. Studies have shown that regular, moderate exercise can actually be helpful to children with asthma in addition to controlling weight problems. Lack of exercise can lead to physical de-conditioning as well as obesity, in turn, can cause asthma to worsen (“Amsterdam News”, 1998). For some asthma sufferers, a proper diet is more than a wishful goal, it’s a necessary step in leading a normal life. In addition to common triggers, food-triggers asthma affect in 6%-8% of asthmatic children but less than 2% of asthmatic adults. Often the triggers is sulfites, sulfite additives or a food allergen such as milk, eggs, peanuts, tree nuts, soy, wheat, fish or shellfish. Dr. Ron Simon of Scripps Clinic and Research Foundation in La Jolla, CA, stated, “sulfites in or added to food can cause potentially life-threatening reactions for asthmatics (“Medical Information”, 1998).” Further research by Harvard Medical School have found that instead of being a by-product of asthma, extra pounds could make people more vulnerable to developing the disease (“Tufts Diet,” 1998).

Even though physical activity has been found to be beneficial to asthmatics. Exercise-induced asthma have been prevalent in our society. As Arateus, in the second century, stated, “If from running, gymnastics exercises, or other work the breathing becomes difficult, it is called asthma.” The phenomenon of shortness of breath after vigorous exercise has been recognized for centuries and for decades; it has been recognized that bronchi-constriction occurs after exercise, it most likely occurs after running. Many athletes and non-athletes have dealt with E.I.A. About 70-90% of asthma suffers discover that exercise and sometimes only exercise can trigger an attack. Before research began, many E.I.A. prone people were unaware of why they were having trouble breathing during exercise, and not inform about treatments. The symptoms, which usually begin after three-eight minutes of a strenuous workout, may include, coughing, wheezing, limited endurance, etc. No one is certain why exercise triggers asthma. In the end, if there is no exercise there will be no exercise induced asthma, but there will be none of the benefits of exercise (Mezei, 1998). In healthy individuals exercise programs and lifestyle initiatives have major benefit in reducing the risk of cardiovascular diseases. There is no reason to believe that this should not occur in patients with respiratory diseases, such as asthma. Many people with asthma of different severity have sufficient ventilatory reserve to allow tolerance of ┬átraining routines. Improvements in fitness ranging from 10% to 92% have been reported (“A.C.E.,” 1996).

Most studies failed to identify any significant changes in the degree of bronchial responsiveness with various aerobic conditioning programs, the potential benefits are valuable and include: 1) improved fitness, 2) decreased frequency and severity of acute attacks, 3) decreased medication usage, 4) decreased school absenteeism, 5) improved self image. Recommendations for evaluation of level of physical activity: 1) Educate the patients about exercise induced asthma, the prophylactic use of drugs, the overall value of exercise, 2) Prescribe drugs to prevent E.I.A. and monitor their effectiveness, 3) Question the patient concerning his/her level of activity and capacity to keep up with peers, 4) If limitations in capacity to exercise are reported by the patient, consider testing, 5) Design rehabilitation program based on the results of the physical fitness (Mezei, 1998).

While physical activities are good for children with asthma, as they bring them into contact with other children and improve their physical fitness, there are contradicting evidence of the specific effects on asthma. Not to denigrate the value of exercise, but rather to ensure the persons involved are aware that it is something to be enjoyed rather than as part of medical treatment (Dennis, 1985). Many questions need to be answered when dealing with an asthmatic person in a fitness setting. They are, 1) Can persons with asthma exercise normally? 2) Are they fit as other people with similar exercise habits? 3) What sort of exercise is needed to make the patient fitter? 4) What effect might regular exercise have on their disease as opposed to their fitness (Mezei, 1998)?

When a disease is in remission and a person have been treated to prevent E.I.A., exercise can proceed normally. There is now enormous amounts of evidence than many asthmatic persons have reduced cardio-respiratory fitness, compared to a control with a similar pattern of physical activity. In other words, the study showed that asthma persons can exercise to a similar intensity as other people, but their overall fitness is reduced. The type of activity an asthmatic performs is not a critical factor but the exercise preferably should be conducted indoors in conditions of warmth and controlled humidity with appropriate warm up and cool down components to reduce likelihood of breakthrough exercise induced asthma. Supervision of exercise prescription is critical, such as in the aspects of progressive increments of intensity and the capacity (“A.C.E.”, 1996).

Some groups have used progressive incremental exercise around the “anaerobic threshold” but without routine a more empirical “trial and error” approach may be effective. This consists of evaluating the tolerability of submaximal exercise at the intensity that will be required during training which expressed in terms of the target heart rate. The persons either will achieve the target heart rate and tolerate steady state exercise during one of these stages or alternatively will show an inability to continue at the required work intensity owing to the breathlessness. If symptoms have remained stable with mild but tolerable breathlessness, the persons may be expected to participate in aerobic exercise program with the achievement of improved cardiovascular fitness (Mezei, 1998).

For persons who cannot sustain exercise of sufficient intensity to improve aerobic fitness because of breathlessness, they require techniques to condition peripheral muscles with the objective of improving mobility and stamina. Persons with moderate to severe chronic airflow limitation can undertake low intensity isotonic training of individual muscle groups to improve the strength and endurance of these muscles and increase overall exercise tolerance. Additional components of this second approach include calisthenics, breathing retraining exercises and walking at the maximum tolerable rate. One can also take a person pulse as a simple method of identifying the few patients who have arterial oxygen desaturation during exercise. Everyone should be supervised, and the exercise prescription should be reviewed periodically (Mezei, 1998).

Strong motivation is required because variations in the disease may interrupt an exercise program and so make the goal of increased fitness difficult to attain. It is important for exercise to be habitual, it should be easily accessible and without adverse sequel.
