context_page_description: Allergies in children are those causes, pathophsiology, treatments, management, practices and control of allergies that develop in children. Up to 40 percent of children suffer from allergic rhinitis. And children are more likely to develop allergies if one or both parents have allergies. Allergies differ between adults and children. Part of the reason for this that the respiratory system in children is smaller. The bronchi and bronchioles are narrower so even a slight decrease in diameter of these airways can have serious consequences. Many children outgrow their allergies.
  The incidence of childhood allergies has increased in the past 50 years.
context_section_description: Each home contains possible allergens that can develop into allergies after exposure to:
  Dust mites
  Dogs and cats
  Other furry pets
  Cockroaches
  Mice and rats
  Plants
  Mold
  Vitamin D deficiency at the time of birth and exposure to egg white, milk, peanut, walnut, soy, shrimp, cod fish, and wheat makes a child more susceptible to allergies. Soy-based infant formula is associated with allergies in infants. Though, in recent years they have been becoming more common in children ages 4 and older.
