A person suffering from severe asthma attack may not respond to inhaled bronchodilators that are usually used. Severe asthma is associated with symptoms of asthmaticus which is potential failure of the respiratory system. Immediate medical attention is needed in such a case.
‘Airway remodeling’ is one long term possible effect of severe asthma. Over time the airways get thicker, making it difficult to breathe through a narrower airway. This can increase risk of having asthma attacks too often. Studies indicate that exposure to pollutants over longer term inflammation and poor control on asthma play a vital role in causing airway remodeling. If medications are not taken as prescribed, there are too many symptoms over a longer period of time, then they simply worsen causing permanent, inflammation, scarring and narrowing of the airways.
What Is The Main Cause Of Asthma?
When a person is exposed to various substances and irritants, it could trigger symptoms and signs of asthma. It is caused by waste particles of cockroach, mold spores, dust mites, pet dander, pollen and other airborne substances.
Asthma is of two types, one is allergic asthma which is caused by exposure to an allergen and the other type is non-allergic asthma which is caused by illnesses like irritants in the air, stress, exposure to extreme weather, flu, cold or some medications. Inflammation of airways is also another cause of asthma.
What Is Atopic Asthma?
One of the most common forms of asthma is Atopic Asthma. Exposure to an allergen triggers, asthma disease. Airways become inflamed and constricted thus causing difficulty in breathing. Variable severity of symptoms is seen. Atopic asthma is more common in children as compared to adults. Development of symptoms can be prevented by avoiding or limiting exposure to the allergen completely, otherwise Atopic Asthma has no cure. Asthma inhalers, anti-inflammatories and bronchodilators are different medications used to manage symptoms of the disease. Corticosteriods are medications that work as long term controllers in Atopic Asthma treatment.
