<p>Allergies are becoming increasingly common all over the world, especially in developing countries like India. As much as 10-20% of the population is thought to be affected by an allergy-related problem. <br /><br /></p>.<p>While the exact reason for its increase is not known yet, there are many theories on the rise. One that has come up is based on hygiene — being too clean ‘confuses’ the immune system which then targets harmless aspects in the environment like pollen or dust mite. <br /><br />The increasing pollution levels is also responsible for the rising trend. As a result, children pay the price with respiratory infections and allergic asthma. Allergies are common if other family members have allergies, though it is not the case always. <br /><br />Many manifestations<br /><br />Allergies are usually caused by the immune system’s hypersensitivity to something in the environment — these usually cause little problem in most people. It can manifest in many different forms. <br /><br />Respiratory allergies are by far the most common. Among these, allergic rhinitis is the most common, but it is often poorly identified. Symptoms are runny nose, blocked nose, sneezing, snoring at night or breathing through the mouth. If untreated, it significantly affects quality of life. It can also lead to development of asthma in later life. Another form of allergy that is becoming increasingly common is that of food.
