Causes of Allergies
Dr. Mario Zambrano, Pediatric Emergency Medicine Physician with Homestead Hospital, says the immune system is not exposed to a lot of things in the uterus and when people are born they are bombarded with allergens. Everything is an allergen: food, milk, dust, mold, pollen, head dander; all are handled by the body differently.
He also explains if there is family history of allergies, the allergy march can be significant with eczema, asthma attacks, sinus problems, among others. He points out as people grow older and their immune system modulates, most children outgrow it.
