Q.129
Read the passage carefully and answer the questions that follow:- (Q. 129 to 133)
Asthma is a respiratory disorder that we have known about for hundreds of years. However, there is still no cure although drugs, such as steroids, and inhalers can alleviate the symptoms of an asthmatic attack, and there is still no known cause. Worryingly, the number of people who suffer from asthma is increasing rapidly. In some countries in the world the disease is becoming more like an epidemic.
Because of the huge increase in the number of cases in the last 30 years, there is a widespread feeling that some kind of lifestyle change is to blame. Since asthma is a disease which impairs breathing, many researchers have thought that a reduction in air quality might have caused the increase in it. However, it is now thought that although the pollution in the atmosphere might exacerbate the condition, it is unlikely to be the cause of it.
For a considerable time, household dust mites were thought to be a possible cause of the condition, but attempts to keep these to a minimum have not reduced the numbers of asthmatic sufferers. Far from it.
Now researchers are looking at diet to find the culprit. The period over which asthma has increased dramatically in some countries coincides with a period when there have been major changes in diet in countries which have seen the highest rates of increase. It was first thought that some kind of dietary allergy might be a major factor.
At the moment, researchers looking for a dietary trigger for asthma are considering whether a lack of antioxidants could be responsible. Their possible protective powers have been much discussed in connection with other diseases. Now, doctors are wondering if a diet rich in things known to contain high levels of antioxidants, such as fruit and vegetables, would prevent asthma, especially if such a diet was followed by pregnant women.
Meanwhile, the schoolbags of more and more children contain an inhaler as well as books and notebooks. Something at school could trigger an attack and they must be prepared.
The use of steroids and inhalers for asthma is to:
heal it
relieve it
cure it
intensify it
