6 Signs of Food Allergies You Should Know

1) Hives

Itching hives that appear after eating certain foods may be a sign of food allergy. Generally, if the raised pink bumps that look similar to insect bites appear within a few minutes to a few hours after eating a specific food, it indicates that you should see a doctor.

2) Sore throat and difficulty swallowing

If your throat starts to swell and swallowing becomes difficult, it is likely to indicate an allergy to the food you ate. Exposure to allergenic foods can cause inflammation in the esophagus, making swallowing difficult.

3) Wheezing

When proteins are marked as 'foreign substances' by the body and an allergic reaction occurs, histamine is released. This compound causes constriction of the airways, leading to a wheezing sound in the throat.

4) Vomiting

Vomiting can be a sign of food allergy, but it can also indicate food intolerance or food poisoning. If vomiting occurs, it may be difficult to determine whether the cause is an allergy or intolerance, so it is best to consult with medical professionals to identify the true cause.

5) Swollen tongue

Swelling of the tongue can affect the ability to swallow. Generally, the tongue returns to its normal size. However, if you experience this reaction, it is advisable to visit a hospital to check for food allergies.

6) Anaphylaxis

Anaphylaxis is a severe and potentially life-threatening reaction that occurs when exposed to an allergen. People experiencing this may have difficulty swallowing or breathing, their heart rate may increase rapidly, and in extreme cases, they may lose consciousness.
