Although there is no definitive cure for oral allergy syndrome (OAS), it may go away in some people. Over time, you may become accustomed to foods that once caused a reaction. There are many ways to manage the condition and reduce or eliminate the symptoms. The best way to avoid an episode of OAS is to avoid the fruits or vegetables that trigger it.
Antihistamines can also help relieve symptoms. Additionally, there are more natural cures and treatments for OAS. Because the allergen is often found on the skin of fruits and vegetables, peeling the skin can help reduce symptoms or prevent a reaction. However, this doesn't always work. Heat can help destroy the protein allergens that cause OAS.
You can usually eat cooked and canned fruits and vegetables because the allergens are turned off. Oral allergy syndrome doesn't usually occur in young children, but symptoms may first appear in older children, teens, and young adults who have been eating the fruits or vegetables in question for years without any problem. Up to one in three people with seasonal allergies may have oral allergy syndrome; however, the exact number isn't clear because the condition often goes undiagnosed. Also known as pollen fruit syndrome or fruit pollen allergy syndrome (PFAS), oral allergy syndrome is a cross-reactivity that occurs in patients with existing allergic rhinitis when they consume certain fruits and vegetables. When taking a medical history, the doctor will ask about the family history of allergies and if the patient has any diagnosed allergies. It is estimated that up to 75 percent of people with pollen allergies have an associated oral allergy syndrome.
The main risk factor for oral allergy syndrome is the presence of a pre-existing pollen or latex allergy. While most oral allergy symptoms will go away when you stop eating the food, it's a good idea to see an allergist for an individual consultation every time you experience food-related allergy symptoms. Reena Mehta is a board-certified allergist who can help you determine your oral allergic reactions and determine if you have oral allergy syndrome in New Orleans, LA. Creating a diet plan for OAS that includes avoiding certain raw fruits and vegetables is a great way to prevent symptoms of oral allergy syndrome. This plan should be tailored to each individual's needs and should be discussed with an allergist.
