Pathophysiology Of Bronchial Asthma

Asthma has usually been considered as something caused mainly by bronchospasm of the smooth airway musculature. However now people know that it happens more so because of the ongoing chronic swelling of the bronchial wall which plays a very prominent role in all this. You can usually eradicate it with the introduction of histamine. An intricate intervention of mediators as leukotrienes, prostaglandins and PAF can actually lead to a somewhat constant inflammation. These changes can be easily seen through the bronchial biopsies and broncho-alveolar lavage fluid even in the case of mild and asymptomatic asthmatic patients. A concept which is now extremely well accepted in the medical circles, anti-inflammatory drugs are being used in the treatment of even the mildest forms of asthma in order to avoid any problems afterwards. Let's learn a bit about the effects of pathophysiology of bronchial asthma from this article.

The basic three constituents to shape up the course of action in pathophysiology of bronchial asthma are: airway inflammation, bronchial hyper-responsiveness and intermittent airflow impediment. There are some specific reasons due to which usually airway inflammation is caused, which are basically a pretty good sign of whether the asthma is sub-acute, acute or chronic. There are many other symptoms as well like over secretion of mucus, bronchial reactivity and edema in the air passage: all of which unfortunately have the same result that is the obstruction of the air flow. Some more examination may disclose permeation of eosnophils in varying degrees, damage of epithelium and mucus hyper-secretion. Some research indicates that things like active T lymphocytes, mast cells, epithelial cells eosnophils and macrophages etc. could also be one of the reasons of the airway inflammation in pathophysiology of bronchial asthma. You will get to know about the severity of the asthma through close examination.

Well one of the other more noticeable symptoms is perhaps the bronchial hyper activity or hyper-responsiveness to external stimuli. You can effectively measure it by causing direct as well as indirect stimulation of the smooth muscle of the airway with substances from mast cells or other mediator-secreting cells. You can also use the airflow obstruction to evaluate the seriousness of asthma. Many various things cause this obstruction like the edema of the airway, remodeling of the airway, the shape of a stubborn mucous plug in the airway, heightened constriction of the bronchi, etc. According to the pathophysiology of bronchial asthma, the first asthma attack is the acute bronchi-constriction as a reaction to a mediator release which happens when you come in contact with some sort of allergens. Now the third component that is the mucus plug formation, could take a couple of weeks to finally grow and disappear.

It is now known that many other diseases can also show the same sort of symptoms as the ones shown in asthma due to which it is extremely important for you to get yourself thoroughly checked up before starting on with any sort of medication. Sometime the pathophysiology of bronchial asthma becomes a controversial and intricate procedure. To correctly diagnose and treat an asthmatic patient will require years of experience and knowledge.
