Asthma
Overview Asthma is a chronic lung disease characterized by difficulty in breathing. Approximately 15 million Americans of all ages are affected by some degree of asthma. Although asthma is the most common chronic respiratory disease in children (diagnosed in 10 percent of all American children), over 2 million older Americans are also asthmatic. Almost one quarter of Americans over 65 report some form of wheezing with or without colds that product shortness of breath. People with asthma have extra sensitive airways. When they encounter certain external stimuli or “triggers,” their airways become irritated and react by narrowing or obstructing and producing mucus. The result is that the air moving in and out of their lungs is obstructed. Asthma SymptomsThis narrowing or obstruction of the asthmatic’s airways has two primary causes. Airway inflammation occurs when the narrowing airways in the lungs become red and swollen. Bronchoconstriction occurs when the muscles that encircle the airways tighten or spasm. The resulting symptoms include:
However, every individual case of asthma is unique. People react in various ways to the triggers such as air pollution, allergies, dust, pollen and smoke. Some people react to one trigger while others are affected by a combination of several triggers. Some react immediately while others have delayed asthma attacks. Some have mild episodes while others have severe reactions. Medications or sudden changes in the weather can also bring on an asthma attack. Individuals with asthma need to keep track of the triggers that provoke their asthma episodes. Asthma management programs help asthmatics track both their exposure to triggers and their degree of responses and the degree of intervention needed using respiratory medications. Common Asthma Triggers
Asthma Treatment and ProductsPeople with asthma need to understand that it is a serious condition. Developing a working relationship with a medical professional and receiving the appropriate medical treatment will enable an asthmatic to learn to live with this lung disease. Usually asthmatics know when an attack is imminent, and they can take the preventative steps to “breathe easier” by using treatments to relax the air tubes in their lungs. Part of following a prescribed treatment or management program is knowing what symptoms to be aware of, what medications to take, when to take these respective medications, how these medications are supposed to counter your symptoms, and when to call your doctor or go to an emergency room if these treatments are not working. Following are some of the predominant respiratory aids utilized in treating asthma:
