Skin reactions caused by nut allergies include rashes, inflammation in the extremities, redness, soreness and hives, says Healthline. Antihistamines and cold compresses are usually helpful in reducing these symptoms. Common upper respiratory problems are a stuffy or runny nose, constant sneezing, a sore throat, and itchy, watery eyes. Antihistamines are also used in the treatment of these symptoms, along with a decongestant to clear up a stuffy nose.
A few hours after consuming nuts, a nut allergy sufferer may experience nausea and stomach cramping, according to Healthline. In more severe allergy cases, vomiting or diarrhea may occur. Patients suffering from nut allergies may not experience all of the symptoms, and the severity of the allergy usually determines the severity of the symptoms.
Nut allergies are caused when a person's immune system recognizes the nuts as a damaging substance, reports Healthline. The first time a person eats nuts, the immune system identifies it as a risk, but no symptoms are likely to occur. However, the next time the nut is introduced into the body, the immune system rejects it and releases the histamine that causes allergy symptoms.Learn more about Allergies
