Food allergies, like all allergies, are the body’s immune system reacting to something that is normally harmless to most people–like the proteins in milk or in eggs. Coming in contact with one of these foods isn’t a problem for some, but if you have an allergy, eating these could potentially become a life or death situation.
Many people confuse a food allergy with food intolerance. They have many similar symptoms, but they’re not the same thing, and the differences between the two are important. Both conditions usually involve the digestive tract, with uncomfortable symptoms like bloating and cramping, and can leave you feeling miserable. But if you have a food allergy, your reaction can potentially be life-threatening. Because an allergic reaction to food can be so serious and severe, it is important to find out if your reaction was caused by intolerance or by an allergy, to decide on appropriate management.
Food allergies have a wide variety of symptoms, which include:
Food allergies are one of the most common causes of anaphylaxis, a rare but serious allergic reaction. Even small amounts of food can cause a reaction.1-5
Anaphylaxis is considered uncommon, but it is important to understand it and to be prepared for it. Talk to your healthcare professional about learning your triggers, and if you have an elevated risk for anaphylaxis.
Globally, as many as 250 million people may suffer from food allergies11 with most people allergic to 1-3 foods. More than 170 foods have been reported to cause allergic reactions.12 Managing food allergies requires dietary changes, of course, but they can affect your lifestyle too. These changes can be challenging and even overwhelming: The constant vigilance necessary to avoid accidental exposure to certain foods can be stressful and frustrating.
It can be difficult to deal with the loss of safety and spontaneity that comes with a food allergy diagnosis. Parties and other social situations should be a time to enjoy and relax; but they can become difficult to negotiate and can potentially be embarrassing. This is the daily reality of
living with a food allergy or caring for someone who has one.
While most people think of children when it comes to food allergies, you can develop an allergy at any age. And many people who say they have some form of a food allergy have diagnosed themselves and haven’t spoken with their healthcare professional about their symptoms. Don’t try to manage the problem on your own. A simple blood test—together with your medical history—can help identify underlying allergen triggers. And knowing if you’re allergic and what you are allergic to may also help you avoid more serious issues in the future. For example, a food allergy reaction sends someone to the ER every 3 minutes.13 Your daily quality of life can improve drastically just from knowing where your symptoms stem from, and managing them appropriately.
Knowing what causes your symptoms can help you get relief. Be sure to consult with your healthcare professional.
