An allergic reaction to oatmeal occurs when a person's immune system mistakenly concludes that the oatmeal or an ingredient in the oatmeal is dangerous. The immune system causes the allergic reaction as an act of protection. Although oatmeal is not one of the most common food allergens, people who suspect they have an oatmeal allergy should consult a doctor or allergist for confirmation or advice.
Symptoms
The symptoms of an oatmeal allergy are the same as the symptoms of any other food allergy, but occur within minutes or a couple hours of an exposure to oatmeal. Gastrointestinal upset may occur, including diarrhea, nausea, vomiting or stomach cramps. Hives or red, itching skin may also occur. Some people may experience swelling of their lips, tongue, throat, face or other areas of the body. Other symptoms include coughing; a runny nose; and watery, itchy eyes.
Considerations
Individuals who believe they may be allergic to oatmeal should see a doctor or allergist to confirm the specific allergy. A doctor may determine the specific ingredient or ingredients in the oatmeal responsible for the allergy. People who know the specific allergen they are allergic to can check food labels to prevent accidentally triggering an allergic reaction by eating a food other than oatmeal.
Treatments
While the best way to treat an oatmeal allergy is to avoid eating it, according to the American Academy of Allergy, Asthma and Immunology, other treatment options are also available. Antihistamine or injectable epinephrine medications can prevent or reduce the severity of an allergic reaction. Individuals should always explore the advantages and disadvantages of each of these medications with a doctor or allergist.
Misconceptions
People who do not have an oatmeal allergy but rather an intolerance to oatmeal may also experience some mild symptoms of a food allergy after eating oatmeal. These individuals may be able to eat small amounts of oatmeal with no symptoms at all and only experience symptoms after eating large quantities of the food, notes the MayoClinic.com. People with a true oatmeal allergy, not just an intolerance, are not able to eat even tiny amounts of oatmeal without experiencing symptoms.
Warning
Although an oatmeal allergy is not normally a cause for concern, people with a severe allergy to oatmeal may experience anaphylactic shock. This can be a potentially life-threatening condition. Symptoms of anaphylactic shock may include lightheadedness, dizziness, rapid heartbeat, wheezing, anxiety or confusion, difficulty breathing, extreme swelling, shock, or fainting, according to MedlinePlus. Individuals who experience these symptoms require medical attention immediately.
