Asthma is a disease of the lung that affects the bronchial tubes or airways. Asthma affects almost 20 million Americans and more than 70% of them also suffer from allergies. There are various different types of asthma. Today, asthma is divided into a number of different types: allergic, non-allergic/intrinsic, exercise-induced, nocturnal, occupational and steroid-resistant asthma.
Allergies and asthma often go hand-in-hand. Allergic rhinitis (also called hay fever) is inflammation of the inside lining of the nose and is the single most common chronic allergic disease experienced by people. Ninety percent of all asthma sufferers have allergic asthma. Allergic asthma is triggered by allergens — substances capable of causing an allergic reaction.
Other type is intrinsic asthma is not allergy-related, in fact it is caused by anything exclude an allergy. This is more common in people who develop asthma as adults. Intrinsic asthma is not possibly to develop in children; its conventional onset occurs after age 40.
Another type of asthma exercise-induced asthma can affect anyone at any age and may be attributed to the loss of heat and moisture in the lungs that occurs with strenuous exercise. Rapid coughing during exercise can be the only symptom of exercise-induced asthma. Exercise-induced asthma includes evidences which occur about 5-20 minutes after beginning an exercise that involves breathing through the mouth.
Occupational asthma occurs straight as a consequence of breathing chemical fumes, wood dust, or other irritants over long periods of time.
An estimated 15 percent of asthmatics have occupational asthma. Many of these substances and conditions are very common and are not normally regarded hazardous. Many people with this type of asthma suffer with runny nose and congestion or eye irritation or have a cough instead of the typical asthma wheezing.
Nocturnal Asthma is often used to describe people who have asthma symptoms at midnight and 8 am. It is triggered by allergens in the home such as dust and pet tetchiness or is caused by sinus conditions. Disturbed sleep from asthma symptoms is very common. Nighttime symptoms can also be a general problem in people who have daytime asthma as well, but then its true nature is more readily identified.
Bronchial asthma is usually an allergic reaction with breathing difficulties and wheezing. Most attacks are occured by hyper-sensitivity to air-borne particles or allergies to foods. Many cause of asthma , strong emotions and stress, cold air, certain medications, including beta blockers, aspirin and other nonsteroidal anti-inflammatory drugs and Gastroesophageal reflux disease (GERD), a situation in which stomach acids back up into your esophagus.
GERD can trigger an asthma attack or make an attack ill. Other reason is respiratory infections, including the common cold and physical exertion, including exercise. The presence of wheezing or coughing in and of itself is not a trustworthy standard for judging the severity of an asthma attack.
