How Long Does It Take For Food Allergy Symptoms To Develop

For some people, an allergic reaction to a particular food may be uncomfortable but not severe. For other people, an allergic food reaction can be frightening and even life-threatening. Food allergy symptoms usually develop within a few minutes to two hours after eating the offending food. The most common food allergy signs and symptoms include:

Ige Mediated Food Allergies

Gluten is a rich source of protein which can be provided ...

The IgE mediated food allergies most common in infants and children are eggs, milk, peanuts, tree nuts, soy and wheat. The allergic reaction can involve the skin, mouth, eyes, lungs, heart, gut and brain. Some of the symptoms can include:

  • Skin rash, itching, hives
  • Swelling of the lips, tongue or throat
  • Shortness of breath, trouble breathing, wheezing
  • Stomach pain, vomiting, diarrhea
  • Feeling like something awful is about to happen

Sometimes allergy symptoms are mild. Other times they can be severe. Take all allergic symptoms seriously. Mild and severe symptoms can lead to a serious allergic reaction called anaphylaxis . This reaction usually involves more than one part of the body and can get worse fast. Anaphylaxis must be treated right away to provide the best chance for improvement and prevent serious, potentially life-threatening complications.

Treat anaphylaxis with epinephrine. This medicine is safe and comes in an easy-to-use device called an auto-injector. You cant rely on antihistamines to treat anaphylaxis. The symptoms of an anaphylactic reaction occur shortly after contact with an allergen. In some individuals, there may be a delay of two to three hours before symptoms first appear.

Cross-Reactivity and Oral Allergy Syndrome

Cross-reactivity also can occur between latex and certain foods. For example, a child who has an allergy to latex may also have an allergy to bananas, avocados, kiwis or chestnuts.

Food Sensitivities: Allergy Versus Intolerance

Manouchehr Saljoughian, PharmD, PhDAlta Bates Summit Medical CenterBerkeley, CaliforniaUS Pharm.

Food allergy is defined as an adverse reaction or abnormal response to a food protein or food additive and is triggered by the body’s immune system . Anaphylactic reactions to food can sometimes cause serious illness and even death. Tree nuts and peanuts are the leading causes of these deadly allergic reactions . In recent decades, the prevalence of food allergy appears to have increased, and even a tiny amount of the allergy-causing food can trigger signs and symptoms such as digestive problems, hives, or swollen face and airways . In people with celiac disease , the gluten in certain foods can initiate a complex immune response and cause severe symptoms.1

Food intolerance is also a reaction to food, but it is not mediated by the body’s immune system and, therefore, it is not an allergy. The symptoms of food intolerance are less bothersome. People often confuse the two, because food intolerance also shows some of the same signs and symptoms as food allergy, such as nausea, vomiting, cramping, and diarrhea.2

Treatment consists of either immunotherapy or avoidance, in which the allergic person avoids all forms of contact with the food to which he or she is allergic.3

Are Food Allergies The Same As Food Intolerances

Food allergies are not the same as food intolerances. Allergies cause a response in your immune system. Allergies can be life-threatening.

Food intolerances cause a response in your digestive system. You may be able to eat a small amount of a food you are intolerant to without experiencing symptoms. Intolerances can be uncomfortable but arent usually dangerous.

Food Allergies In Children

No parent wants to see their child suffer. Since fatal and near-fatal food allergy reactions can occur at school or other places outside the home, parents of a child with food allergies need to make sure that their childs school has a written emergency action plan. The plan should provide instructions on preventing, recognizing and managing food allergies and should be available in the school and during activities such as sporting events and field trips. If your child has been prescribed an auto-injector, be sure that you and those responsible for supervising your child understand how to use it.

In November 2013, President Barack Obama signed into law the School Access to Emergency Epinephrine Act , which encourages states to adopt laws requiring schools to have epinephrine auto-injectors on hand. As of late 2014, dozens of states had passed laws that either require schools to have a supply of epinephrine auto-injectors for general use or allow school districts the option of providing a supply of epinephrine. Many of these laws are new, and it is uncertain how well they are being implemented. As a result, ACAAI still recommends that providers caring for food-allergic children in states with such laws maintain at least two units of epinephrine per allergic child attending the school.
