What is Asthma Pathophysiology?

Asthma, which is a chronic disease in the lungs, is characterized by:

• Hyper responsiveness of the airways to different stimuli like viruses, allergens or exercise

• Inflammation of the airways

• Reversible narrowing or obstruction of the airways

Asthma pathophysiology indicates that inflammation in the airways is an essential part of the pathology of asthma. This is the underlying process which drives and maintains the process of asthmatic inflammatory.

The stimuli trigger the release of inflammatory mediators from mast cells, eosinophils, macrophages and other cells in the airways. Increase in mucus is also triggered along with the contraction of the airways.

In many cases, both environmental and genetic factors are involved in asthma pathophysiology. Most patients who develop asthma early on are those who have familial histories of allergies, eczema or asthma.

An asthmatic person’s immune system is hypersensitive which means that even the mildest airborne pathogens can cause inflammation in the airways. Common triggers are: tobacco smoke, pet dander and pollen.

Heavy breathing from too much physical activity and cold air can irritate the throat and lead to asthmatic attacks in some people.

If you experience frequent or chronic breathing problems, you should visit your doctor to know further about asthma pathophysiology and the various methods of treatments for that condition. A doctor can better explain in detail the reasons why asthma occurs. He can also aid in identifying what particular stimuli triggers your attacks.

The most effective way of overcoming asthma is learning which triggers to avoid. There are inhaled medications a doctor can prescribe to help out in fighting the elements of this chronic disease. The medicines work to relax the muscle tissues in the airways making them expand for better breathing.
