6. Signs People Affected by Asthma
The number of asthma triggers that could potentially explain most of the different ways in which asthma can present. In most cases, the disease begins in childhood age 2 to 6 years. In this age group, the cause of asthma is often linked to exposure to allergens, such as mites (dust mites), cigarette smoke, and respiratory viral infections. In young children, less than 2 years, asthma can be difficult to diagnose with certainty.
Wheezing (wheezing) at this age often follows a viral infection and may disappear later, without ever leading to asthma. Asthma, however, can thrive again in adulthood. Asthma arising in adulthood is more common in women, most part-age, and often follows a respiratory infection. Triggers in this group generally nonalergi nature.
Types: Asthma Allergic (extrinsic) asthma and nonalergi (intrinsic)
Your doctor may refer to asthma as "extrinsic" or "intrinsic". A better understanding of the nature of asthma may help explain the differences between them. Extrinsic, or allergic asthma (allergic asthma), are much more common (90% of all cases) and typically develops in childhood. Approximately 80% of children with asthma have allergies documented. Typically, there is a family history of allergies. Moreover, other allergic conditions, such as nasal allergies or eczema (eczema), often also present. Allergic asthma often disappear (go into remission) in early adulthood. However, in 75% of cases, asthma and then comes back.
Intrinsic asthma represents approximately 10% of all cases. He usually develops after the age of 30 years and are typically not associated with allergies. Women are often more involved and many of the cases seem to follow a respiratory infection. The condition can be difficult to treat and symptoms are often chronic and throughout the year.
