The study was done on 8,306 patients, and 776 of them were already having some reactions to peanuts. The research concluded that it is usually higher in males than females and 20 percent of the food allergies developed by children are peanut allergies.
The symptoms of peanut allergies are itching or prickling in or around the mouth and throat, skin reactions, such as hives, redness or swelling, digestive problems, such as stomach cramps, diarrhea, nausea or vomiting, shortness of breath or wheezing, tightening of the throat and runny nose.
Anaphylaxis is the most common life threatening cause of peanut allergy. It is a medical allergy and requires medication like epinephrine injection. The symptoms of Anaphylaxis are swelling of the throat, constriction of airways, rapid pulse, a severe drop in blood pressure, lightheadedness, dizziness and loss of consciousness.
The factors that trigger the peanut allergy are past allergy to peanuts, age, family history of allergies and Atopic dermatitis. Some people think that food allergies are related with childhood hyperactivity, but there is no link between these two.
There is no specific treatment for peanut allergy, but desensitization is an option of treatment. The only way by which you can avoid the allergy is avoiding peanuts and products related to it. For minor allergic reactions you can use antihistamines, reported Mayoclinic.
