Food Allergy in Adults: Causes, Symptoms, Treatment

If you still think that food allergies occur only in children, we have bad news: in half the cases, an allergic reaction manifests itself in adults. We talked with an allergist Ekaterina Pushkova and figured out where the food allergy comes from and what are its signs.

According to the


published in The Journal of Allergy and Clinical Immunology, in 45% of cases, an allergy develops in a person in adulthood. Of course, allergies can occur if you try a product for the first time. However, the main feature of allergies in adults is that it can cause food that you have eaten more than once.

Allergy appears due to a malfunction of the immune system: the body confuses a harmless substance with something that can be harmful, and begins to produce antibodies to fight this substance.

Yes, you can’t exactly to say whether there will be an allergy or not, but it is in your power to prevent a severe allergic reaction. For example, if you have a genetic predisposition to allergies, then some types of food should be treated with caution. Research by the FDA (Food and Drug Administration, one of the agencies of the US Department of Health and Human Services) suggests that more than

Predict how the allergy will manifest itself , impossible: your skin may itch, rhinitis, digestive problems may occur. And these are just the most harmless reactions to an allergen.

In addition, the reaction to the same product may manifest itself differently each time.

If within a few hours after eating you have appeared One of the above symptoms is most likely you have a food allergy. Here are five signs that should alert you.

Red spots on the skin, itching, dermatitis and even eczema - all these are signs of an allergic reaction. If you notice redness around the mouth, on the arms or legs that appeared after eating, chances are you are allergic to something in your plate.

According to

Food Allergy Research. Education

(a nonprofit organization that educates and research on anaphylaxis and allergic reactions to food), weak heart rate, and low blood pressure can be a sign of allergies.Of course, if you do not measure pressure every time after eating, it will be difficult to track any changes. Nevertheless, if after eating you have a weak pulse and you feel weak and dizzy, do not brush it off.

Another sign of an allergic reaction is burning and tingling in the mouth and throat.

Because of this, a dry cough appears. Typically, the body reacts this way to vegetables and fruits, which contain components similar to those found in pollen. Typically, burning and tingling disappears a few minutes after you swallow food that contains allergens.

If you find it difficult to swallow food, you feel stiff in the sternum and burning in the esophagus, you may have eosinophilic esophagitis - inflammation of the esophagus, which occurs as an immune response to an allergen. This happens if the immune system takes a substance for something harmful and sends eosinophils (one of the types of white blood cells) into the esophagus in order to destroy this substance.

All this can cause discomfort during swallowing and lead to a jam in the throat.

Food intolerances, allergies, and poisoning may have some of the same symptoms. Therefore, if you have problems with the gastrointestinal tract, do not blame stale food or lactose intolerance for everything. Of course, distinguishing problems with digestion of food from an allergic reaction is not easy, but still it is worth remembering: the symptoms of allergies are likely to be more serious.

If you found one or a few of these symptoms, see your doctor and get ready to answer at least three questions:

  • What and how much did you eat?
  • How much time has passed after eating before the first symptoms appear?
  • How long have you been seeing symptoms?

In allergies, like in any other disease , little is pleasant: because of the risk of an allergic reaction, you will have to limit your diet and possibly abandon your favorite foods. But the sooner you see a doctor, the better. Indeed, almost always, as soon as we find out the cause of the ailment, it is in our power to do everything to improve the quality of life and focus on other, equally important things.
