Asthma Risk Factors And Prevention
Asthma is a malady which has rendered many persons’ lives, whether men, women, children, or young persons a hell and deprived them from the enjoyments and benefits of life. It is a height of ignorance to say that asthma is incurable or else claim that it is fully curable. In fact, this malady is fully manageable and treatable. No doubt, asthma can be contained and confined if the patient knows the contributory and precipitatory causes which trigger an attack of asthma.
The symptoms of bronchial asthma are caused by an inflammatory reaction within the bronchial wall involving many cells, mediators and cytokenes. Eosinophils, mast cells, lymphocytes and other cells. The inflammatory process results in hyper-responsiveness of the bronchi. The respiratory tract narrow easily in response to such wide range of stimuli. This may result in coughing, wheezing, chest tightness, and shortness of breath, these symptoms often being worse at night. Narrowing of the airway is usually reversible, but in some patients with chronic asthma the bronchial wall inflammation may lead to irreversible obstruction of air-flow.
It is often asked whether there is any particular age, sex, condition, food, climate, emotional upset, habit, allergic factor which could cause onset of an asthmatic attack. The answer is that factors like age and sex do not seem to have any major role in asthma, though its onset is from the childhood itself and more men than women are the usual victims.
Heredity plays a prominent role here. If the parents suffered from asthma at the young age, it does not imply that their offspring will also develop the same symptoms at the identical age but risk factor is always there and children of asthmatic patients have to remain on the guard right from the days of childhood. If preemptive steps are taken through proper education, self-management, precautions and approach, the patient may be able to encounter an attack with far less disturbing symptoms or, if an attack occurs, its duration may be short-lived.
