Mild allergies are an inconvenience, but severe allergies can be life-threatening. Mild allergy symptoms may not be extreme, but they can affect the entire body. Mild symptoms include skin rash, hives, runny nose, itchy eyes, nausea, or stomach cramping. Severe allergy symptoms are more extreme. Swelling caused by the allergic reaction can spread to the throat and lungs, causing allergenic asthma or a serious condition known as anaphylaxis.
Different people react differently to the same allergens. Some people may just have an uncomfortable rash, while others may go into anaphylactic shock. In any case, signs and symptoms of a food allergy usually develop within a few minutes to an hour after having ingested the food. The most common signs and symptoms of a true food allergy include: 1  tingling in the mouth; 2  itching or eczema; 3  swelling, especially on the lips, face, throat, and neck; 4  wheezing, nasal congestion, and a general difficulty in breathing; 5  abdominal pain, nausea, and vomiting. 6  dizziness, light-headedness, and fainting.
