Not all children who react to a certain food have an allergy. They may have food intolerance. Unlike food allergy, this condition doesn’t cause the immune system to react. With food intolerance, the body has trouble digesting a certain food.
Even though food allergy and food intolerance can cause some of the same symptoms, their treatments may differ. The way to prevent both conditions is to stay away from the foods that cause symptoms. Your child’s doctor can diagnose and treat the condition causing reactions to food.
There are many different causes of food intolerance. Some examples include:
The symptoms usually come on over time and may only happen when your child eats a lot of the food. They often involve the digestive system.
Staying away from the foods that cause symptoms is the best treatment. Your child’s doctor may suggest other steps to prevent a reaction.
