want to know the differences between asthma and COPD ?

Answer 1

How Does COPD Differ from Asthma?

Although COPD and asthma have similar characteristics such as the signs of coughing and wheezing, they are two distinct conditions in terms of disease onset, frequency of symptoms and reversibility of airway obstruction.

1. The onset of asthma typically occurs during childhood or adolescence. COPD most often develops in smokers and former smokers who are in their mid-40s.

2. Exacerbations of asthma -- characterized by recurrent wheezing, shortness of breath, chest tightness and cough -- often have identifiable triggers such as allergens, cold air or exercise. However, exacerbations in COPD patients are commonly caused by respiratory tract infections.

3. With treatment, asthma patients have near-normal lung function and are symptom-free between exacerbations. COPD patients rarely experience a day without symptoms. Airflow obstruction in COPD sufferers is only partially reversible with smoking cessation and bronchodilator use.

Despite these distinctions, COPD is often misdiagnosed, and persons with COPD are treated instead for asthma. In fact, a survey of 75 primary care physicians revealed that they prescribe similar medications for COPD and asthma even though the appropriate treatments differ. The first-line maintenance therapy for most patients with asthma is an inhaled corticosteroid, with the addition of a bronchodilator if needed to control symptoms. However, the reverse is true for the treatment of COPD. Bronchodilators are the first-line maintenance treatment for COPD. Treatment with inhaled corticosteroids is reserved only for selected patients whose COPD is not adequately managed with bronchodilators. Survey findings also showed that primary care physicians had a low basis of suspicion for COPD.

Answer 2

Difference Between Copd And Asthma

Answer 3

Both asthma and copd are a disease of the lungs. asthma however is usually a reversible condition. Both are obstructive diseases where it is hard to get the air out of the lungs. Copd is permanent damage to the lungs (not reversible) where the elasticity of the lungs is damaged. Like a rubber band that has been stretched and does not go back into shape. Asthma has swelling and irritation in the lungs which clog up the bronchial tubes but when the swelling and inflammation is cleared the lungs breath normal. Hope that helps

Answer 4

Asthma is an acute inflammation of the airways, which can be brought on by stress or inhalation of an irritant such as cigarette smoke or a chemical irritant. COPD or (Chronic Obstructive Pulmonary Disease) Is a blanket term for Emphysema and Chronic Bronchitis which is an air flow obstruction usually associated with cigarette smoking, which over time makes the lungs less compliant (stiffening) and which makes breathing (exhaling) very difficult ! I could go into more detail, But this should give you an idea.

Answer 5

From my husband who's a respiratory therapist: COPD is a combination of athsma and bronchitis. Asthma is inflammation and narrowing of the airways. Bronchitis is exudate (mucous) being formed from a reaction to an irritant. Airflow is obsturucted by the mucous formation. Mucous isn't involved with athsma. If you have more bronchitis, you cough up more. The amount of mucous you cough up determines the percentage of bronchitis in the COPD.

Answer 6

Asthma is a restrictive lung disease...meaning it is difficult to get the breath into the lungs.

COPD is an obstructive lung disease...meaning it is difficult to exhale the breath out of the lungs.

Answer 7

Chronic obstructive pulmonary disease is a destruction of alveolar walls and a ballooning of the lungs most commonly due to chronic bronchitis.
Asthma is a possible cause of it.
