Can adults develop a food allergy?

Can adults develop a food allergy?

Most food allergies start in childhood, but they can develop at any time of life: It isn't clear why, but some adults develop an allergy to a food they used to eat with no problem. Sometimes a child outgrows a food allergy only to have it reappear in adulthood. If you have a food allergy, you'll need to avoid the offending food. An allergic reaction can quickly put your immune system into a state of emergency, affecting numerous organs in your body. For certain people, even a tiny amount of the food may cause symptoms such as digestive problems, hives, facial swelling or trouble breathing. Some people with a food allergy are at risk for a life-threatening reaction (anaphylaxis) that requires emergency treatment. Don't ignore a reaction that occurs shortly after eating a particular food. See your doctor to determine what's causing it. Even if you've had a relatively mild reaction in the past, subsequent allergic reactions may be more serious. Get emergency treatment for any severe food reaction. ...Read more
