Your doctor may mention asthma as being “extrinsic” or “intrinsic“. An improved understanding of the asthma nature can aid in explaining the variances among them. Extrinsic, or allergic asthma, is more common (90% of all cases) and characteristically progresses in childhood.About 80% of children with asthma also have recognized allergies. Naturally, there is a family history of allergies. Moreover, other allergic conditions, such as nasal allergies or eczema, are often also present. Allergic asthma often goes into lessening in early adulthood. Still, in 75% of cases, the asthma returns later.Intrinsic asthma characterizes about 10% of all cases. It generally develops after the age of 30 and is not naturally related to allergies. Women are more often involved and many cases seem to follow a respiratory tract infection. The condition can be hard to treat and symptoms are often enduring and constant.The most common form of asthma is Allergic asthma or extrinsic asthma.This type of asthma results from an allergic reaction. The immune system usually exists to ward off infection. In allergic asthma, nevertheless, body senses allergens, which would normally be mild, as foreign and mounts an attack against them. This attack can lead to asthma symptoms.
Symptoms of Allergic or Extrinsic Asthma
The symptoms of allergic asthma and non-allergic asthma are the similar and consist of:
- Chest tightness.
- Shortness of breath.
- Chronic cough.
Allergic asthma symptoms can be triggered by:
- Tobacco smoke.
- Animal dander.
- Dust mites.
Allergic asthma,in general, is triggered when you inhale one of the before mentioned triggers. Once these triggers are inhaled, a complex reaction, referred to as the pathophysiology of asthma, begins, resulting in asthma symptom development. Much of this results from the IgE development.You are most likely a topic if you have allergic asthma, and inherit a tendency towards allergy. The immune system develops an exaggerated response to the earlier mentioned allergens or triggers as a result. Body senses these allergens, recognizes them as foreign, and prepares to fight them off as a foreign invader.
This process, often referred to as the allergic cascade, occurs in 3 steps:
- Sensitization : Exposure to an allergen causing development of IgE is first.
- Early phase response : Upon allergen re-exposure, IgE attacks or binds to the allergen, which now causes the other chemical release, called mediators that cause acute inflammation and bronchoconstriction.
- Late Phase response : Eosinophil releaseafter allergen binding and IgE causes more inflammation and symptoms several hours after the exposure.
Treating Allergic Asthma
Allergic asthma treatment primarily involves three main components:
- Peak expiratory flow and asthma symptoms monitoring.
- Allergic asthma triggers evasion.
- Medication treatment.
Non-allergic asthma is asthma in someone who doesn’t have allergies. And we can know this is in numerous ways. Allergies are things like allergic rhinitis or hay fever, and there are people who clearly do not have any of the diverse ways that allergies exist.
There’s also testing, and one method is to use what’s called a skin print test where many diverse allergens or substances that cause allergic reactions are given to the patient and reactions to these tests are looked up to. There are also blood tests which can measure exact mixes in the blood that show that the person has been bare to this and developed a reaction to it, and can help in relating whether or not the person has the possible for allergies.
