I just took our 13 year old son to the allergy doctor 2 days ago. He was diagnosed with Oral Allergy Syndrome. He always told me that eating apples and certain other fruits made his lips swell or his throat/mouth feel itchy. At first, I thought maybe he just was eating carelessly and getting the apple juice on his face when he ate apples, and it was irritating his skin because of the acid. Then I wondered if maybe I'd bought a different variety than I usually buy and that was the cause. It wasn't until this summer that I finally realized the extent of the problem. I noticed that he was avoiding foods that he used to enjoy eating: apples, watermelon, bananas, etc. When my son told the allergy doctor about the problems with certain fruits, the doctor said that he expected him to be very allergic to trees, grasses, and weeds because the pollens from those can be very similar to the pollens in certain fruits. For example, someone allergic to birch trees may also be allergic to apples. When they skin tested my son, he reacted to ALL of the trees, grasses and weeds. The doctor was right!! We also found that he's allergic to apples, strawberries, bananas, and watermelon. He also reacted to all the tree nuts and some environmental allergens. He now has to undergo allergy shots because the Dr. said that due to his young age and the severity of his reactions, he needed to be desensitized since most allergies will only get stronger as a person gets older. My son also has to have an Epi-pen. The doctor said that although the fruits only cause swelling in his mouth and itching now, that at some point he will have a more severe reaction. If you are showing any symptoms of fruit allergies, PLEASE see an allergist and get tested. I could not believe how bad my son's back looked after he had the testing done. I felt bad because I thought he only had seasonal allergies and didn't realize how severe it really was. In fact, he was so allergic to all the trees, etc. that just from being skin tested and the small amounts they used, he needed to have cream rubbed onto his back to help with the itching. And, before we could leave the office he was coughing and clearing his throat because it was feeling "thick", and they had to give him some allergy medicine to help stop his reacting to the pollens. Please stop eating any fruit that bothers you and get it checked out!!
