Symptoms of food allergies may range from mild to severe and they may come on suddenly or develop over several hours.
Because a person’s immune system may react to a very small amount of the allergen, food allergies are particularly dangerous and potentially life threatening, especially if breathing is affected.
Because of this, people with asthma are at an increased risk for a fatal allergic reaction to food.
Mild symptoms related to a food allergy may
stuffy or runny nose
itchy, watery eyes
Severe symptoms of an allergic reaction to food
difficulty breathing, including wheezing
swelling of the lips, tongue or throat
hives (an itchy, blotchy and raised rash)
dizziness or faintness
nausea or vomiting
If you discover these symptoms it is advisable that such food(s) be avoided.
