Not everyone with a peanut allergy develops extreme symptoms. Signs of a mild allergy to peanuts will develop within minutes of eating a food that contains peanuts. Peanuts may be found in unlikely foods, such as in chocolate, ice cream and some bread. The allergy is common amongst young children. Make an appointment with your doctor if you suspect that you have an allergy to peanuts.


Mild signs of an allergy to peanuts are caused by the production of histamine, antibodies and other chemicals in the body. Although peanuts are not harmful for human consumption, your body’s immune system can make the mistake of identifying the peanut proteins as dangerous. Immunoglobulin E, or IgE, antibodies are created with histamine to defend the body. These chemicals typically protect the body from infection, but during an allergic reaction they’re the cause of most symptoms.

Skin signs

A common sign of a minor peanut allergy is tingling or itching in the skin. This sensation may occur around the mouth, lips, tongue or throat and will only last for a few minutes. Skin irritation can cause the skin to become itchy and develop common allergic skin rashes, such as hives and eczema. Allergic rashes can appear anywhere on the body and typically last for a short time. You can treat minor skin rashes from a peanut allergy with hydrocortisone, according to the American Academy of Allergy, Asthma and Immunology.

Respiratory signs

The respiratory system can be affected by a peanut allergy, causing minor asthma symptoms, sinus complications and light-headedness. Common respiratory signs of a minor peanut allergy include difficulty breathing, shortness of breath, coughing, chest discomfort and wheezing. If your sinuses become inflamed, you may experience runny nose, sneezing, nasal congestion, postnasal drip, facial tenderness and sinus headaches.

Digestive signs

A minor peanut allergy can cause minor digestive problems, such as nausea, diarrhoea, cramping, bloating, gas and vomiting. Taking medication for an upset stomach is not effective for digestion complications from a peanut allergy. You need to allow your body to expel the peanut proteins. Most digestive symptoms will subside within a few hours.
