Asthma Asthma is a common long term inflammatory disease of the airways of the lungs. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. These episodes may occur a few times a day or a few times per week. Depending on the person they may become worse at night or with exercise. Asthma is thought to be caused by a combination of genetic and environmental factors.

Complications of Asthma For some people, asthma causes ongoing chronic inflammation of the airway. This can lead to permanent structural changes in the airways if not properly treated. This is known as airway remodeling. It includes all the alterations in structural cells and tissues in an asthmatic airway.

Asthma in Dogs Although some cases of asthma in dogs are preceded by infectious disease such as kennel cough, in most cases, asthma is an allergic reaction in the dog's airways triggered by some airborne pollutants and irritants, such as exhaust gas, cigarette smoke, house dust, pollens, and so on.ommon conventional treatment for asthma in dogs is the use of two classes of medications: Bronchodilators (theophylline, aminophylline, pentoxifylline, and terbutaline) and corticosteroids (prednisolone, prednisone, and methylprednisolone).

Medication SummaryQuick reliefLong-term control Asthma Medication - Medication SummaryQuick reliefLong-term control. 1  Asthma medications are generally divided into two categories... 2  Quick relief medications are used to relieve acute asthma exacerbations and to prevent exercise-induced bronchoconstriction (EIB) symptoms. These medications include short-acting beta agonists (SABAs), anticholinergics (used only for severe exacerbations), and systemic corticosteroids, which speed recovery from acute exacerbations.

How Does Asthma Affect the Body? Introduction to Asthma. Asthma is a disease of the lungs that affects more than 20 million Americans, according to the Asthma and Allergy Foundation of America.It is a chronic condition that repeatedly causes the airways in your lungs to become narrowed and inflamed. Infections--illnesses that cause respiratory problems, such as the common cold. • Exercise-induced--brought on by physical activity. • Cold temperatures--cold and dry air can irritate airway and cause asthma. • Airborne pollutants and irritants--includes cigarette smoke, wood smoke and chemical fumes.

Can Asthma Increase COPD Risk? And drugs that help asthma—bronchodilators, inflammation-fighting steroids—are much less effective for COPD. COPD misdiagnosed as asthma. Unfortunately, the significant resemblance between the symptoms of the two diseases often causes one to be mistaken for the other, which can lead to improper treatment. A study published in the Journal of Asthma in 2006 estimated that more than 50% of people with COPD are misdiagnosed with asthma.

Asthma Asthma ranges from mild to severe. Some people have only occasional, mild symptoms. Others have nearly constant symptoms with severe, life-threatening flare-ups. During an asthma attack, the airways become more inflamed than usual. They narrow as the muscles surrounding them constrict. Mucus produced by the inflammation fills the narrowed passageways. As a result, the flow of air is partially or completely blocked. Asthma affects the lung's larger and smaller airways.
