Many of the symptoms of allergic and non-allergic asthma are the same but the triggers may be different.
ALLERGIC ASTHMA TRIGGERS
Allergic asthma, or allergy-induced asthma, is the most common form of asthma, according to the American Academy of Allergy Asthma & Immunology (AAAAI). The Academy explained that the symptoms of patients with allergic asthma are triggered by inhaling allergens – harmless substances such as dust mites, pet dander, pollen, or mould. “If you are allergic to a substance, this allergen triggers a response starting in the immune system.
“Exposure to allergens may trigger the symptoms, but the real culprit in allergic asthma is the immunoglobulin E (IgE) antibody. The IgE antibody is produced by the body in response to allergen exposure. The combination of the antibody with allergens results in the release of potent chemicals called mediators. The mediators cause inflammation and swelling of the airways, resulting in symptoms of asthma.”
ALLERGIC ASTHMA SYMPTOMS
Patients with allergic asthma experience the same symptoms as patients with non-allergic asthma: shortness of breath, wheezing, coughing, and chest tightness. However, as the Allergy & Asthma Network explained, patients with allergic asthma may also experience common allergy symptoms including:
- Runny nose, usually with clear or pale-coloured mucus
- Red, watery eyes
- Itching around the nose, mouth, or eyes
TREATING ALLERGIC ASTHMA
“Bronchodilators, which loosen up the muscles around the aviation routes, permit you to inhale simpler,” Dr Angela Haczku explained in Allergic Asthma and its Treatments published in the Journal of Allergy & Therapy (Vol.12 Iss.6, 2021). “These medications are frequently used to stop asthma manifestations after they've begun. At times, you use them day by day to help control your asthma. Mitigating drugs are utilised for long haul control of asthma. Different prescriptions can keep your aviation routes from fixing or square the arrival of synthetic substances that trigger the hypersensitive response. Hypersensitivity shots or tablets can prepare your safe framework to quit going overboard to explicit allergens.
A respiratory immunologist with a research focus on the pathogenesis of allergy, asthma, COPD, and pulmonary infections, Dr Haczku said that specialists don't know precisely why some patients have susceptible asthma, and others don't, even though it can run in families. “Individuals with hypersensitive asthma are additionally bound to have atopic dermatitis, skin inflammation, and susceptible rhinitis or hay-fever, as are other relatives,” she said. “Scientists keep on examining data on various quality varieties that may make an individual more inclined to susceptible asthma. They are likewise inspecting how individuals with various qualities react to medicines. For instance, individuals with explicit qualities may not react to specific medicines. Every person with susceptible asthma may have various triggers. For certain individuals, these allergens cause no side effects. In others, they can make breathing troublesome and trigger an asthma assault.
“At the point when an individual is delicate to a specific allergen and encounters openness to it, their invulnerable framework begins delivering the compound IgE. Overabundance in the body would then be able to trigger the arrival of different substances that may cause aviation route irritation,” explained Dr Haczku. “Abundance measures can prompt an interaction that makes the aviation routes more modest. Breathing through more modest aviation routes is more troublesome than through bigger ones. The outcome can be an asthma assault.”
CONFIRMING ALLERGIC ASTHMA
“Specialists will start diagnosing susceptible asthma by getting some information about their indications, including what aggravates these better,” Dr Haczku said. “Then, a specialist may perform respiratory capacity tests to decide the effect on the aviation routes. They may likewise embrace skin testing to decide whether an individual has a response to explicit allergens.
“Unfavourably susceptible asthma is not quite the same as different sorts of asthma since it's anything but a safe framework reaction. Other asthma types are a response to different aggravations that cause the aviation routes to get more modest or open and close more without any problem. Active work, openness to smoke, or having a respiratory contamination can prompt an asthma fuel in these asthma types.
“The most complete indication of hypersensitive asthma is the point at which an individual tests positive for an allergen, alongside having asthma side effects after openness to that allergen. Tracking this down can assist a specialist with deciding if hypersensitive asthma is the reason,” Dr Haczku concluded.
