Before we present the typical symptoms of asthma, we should dispel some common myths about this condition. This is best achieved by conducting a short true or false quiz.1. T or F - Asthma is “all in the mind.”2. T or F - You will “grow out of it.”3. T or F - Asthma can be cured, so it is not serious and nobody dies from it.Types and Causes of Asthma Asthma is a disease of the lung that affects the bronchial tubes or airways. The term “asthma” comes from the Greek meaning, “to breathe hard.” Medical terminology defines the condition as reversible obstructive airway disease (ROAD). Unlike other conditions that obstruct the airways, such as cystic fibrosis, chronic bronchitis and emphysema, asthma does not affect sufferers all of the time.SymptomsAsthma Symptoms Do you have to wheeze in order to have asthma? Not at all! Discover the specific signs and symptoms of asthma. Find out how early treatment can help you manage asthma symptoms and live an active life.Asthma Attack Symptoms Do you know the early warning signs of an asthma attack? Read more about asthma attack symptoms so you can prevent an emergency.Types of AsthmaChild-onset asthma: When asthma does begin in childhood, it often does so in a child who is likely, for genetic reasons, to become sensitized to common “allergens” in the environment (atopic person). When these children are exposed to house-dust mites, animal proteins, fungi, or other potential allergens, they produce a type of antibody that is intended to engulf and destroy the foreign materials. This has the effect of making the airway cells sensitive to particular materials. Further exposure can lead rapidly to an asthmatic response. This condition of atopy is present in at least one-third and as many as half of the general population. When an infant or young child wheezes during viral infections, the presence of allergy (in the child itself or a close relative) is a clue that asthma may well continue throughout childhood.Extrinsic AsthmaIt causes due to the external triggers such as pollen, cigarette smoke, dust mites and perfumes.It develops during childhood since children are more susceptible to allergens. [Childhood Asthma]An allergen is a foreign particle which enters the body and your immune system over reacts to these harmless items forming antibodies which are normally used to attack viruses or bacteria. Mast cells release these antibodies as well as other chemicals to defend your body.Exercise-induced asthma, or E.I.A., is a medical condition characterized by shortness of breath induced by sustained aerobic exercise. It shares many features with other types of asthma, and responds to some typical asthma medications, but does not appear to be caused by the same inflammatory reaction as the other types.Asthma is a chronic (long-term, ongoing) inflammation (irritation) of the breathing passages (bronchi) of the lungs. Asthma is characterized by sudden attacks or periods of bothersome or severe symptoms separated by periods of mild symptoms or no symptoms at all. Asthma is an inflammatory reaction that is triggered by external factors or specific situations. When a person with asthma is exposed to one of his or her triggers, the inflammation worsens and symptoms ensue.
