What are the Symptoms of a Peanut Allergy?

Peanut allergies are one of the most common food allergies that people experience, and one of the most serious as well, as explained by the expert staff at the Mayo Clinic (see Resources). Unlike other food allergies that children may develop when they are young and then grow out of, a peanut allergy is most likely permanent. Symptoms can range from mild to serious enough to send a person into anaphylactic shock if he even comes in close contact with peanuts. People who have life-threatening allergies to peanuts and other tree nuts must carry an epi-pen to avoid catastrophic complications.

Skin Reactions

• Symptoms of a peanut allergy can include several adverse reactions centered on the skin. Hives, a red rash, itchiness and localized swelling may occur.

Tingling

• A tingling or itchy sensation in your mouth and throat may occur as a peanut allergy symptom.

Respiratory Problems

• Respiratory symptoms include nasal congestion, wheezing, having difficulties catching your breath and feeling a tight sensation in your chest.

Digestive Issues

• Peanut allergy symptoms can extend to the gastrointestinal tract. Diarrhea, cramping and nausea are common.

Anaphylactic Shock

• Severe allergic reactions to peanuts can send a person into anaphylactic shock, meaning the blood pressure drops dangerously low. Lightheadedness and a very rapid pulse may also occur. Some people lose consciousness during anaplylaxis.
