Early diagnosis and proper treatment of allergies is important. According to the National Institutes of Health, allergies account for 2 million missed school days each year. And, on any given day, more than 10,000 children are absent from school because of allergies. The physical symptoms of allergies, such as sneezing, runny nose, and watery eyes, can make a child feel bad. But they can also cause a child to become fatigued and irritable and to have limited attention span and a decreased ability to concentrate, which may compromise performance in school.
Allergies can begin at a very young age.
Like adults, childhood allergies mean his or her body reacts to substances called allergens.
