Symptoms of Food Allergy
Symptoms
It is not always easy to tell when a person has a food allergy, because there are many different symptoms. These include:
- rash (a rash high, pink and itchy)
- itchy throat
- stomach ache
- nausea or vomiting
- diarrhea
- swelling, especially around the mouth and face
- irritated eyes
- nasal congestion / runny nose
- other rashes, including eczema
- wheezing or simply breathing problems
- difficulty swallowing
- rapid heart rate
- dizziness
- in infants and young children, slow growth or blood in the stool
In severe cases, it may be something called anaphylaxis. This allergic reaction throughout the body combines many of the above symptoms and can cause death if not treated immediately.
Duration
While most children outgrow food allergies with age, some experience them into adulthood. Teens need to know they had food allergies in children and not think that they have been overcome. In particular, allergies to peanuts (groundnuts), tree nuts, fish and shellfish are not exceeded, usually.
