Food allergies occur when the immune system mistakenly identifies a harmless food protein as a threat to the body. Instead of ignoring it, the body reacts as if it is fighting a virus or bacteria. This immune response can trigger symptoms ranging from mild discomfort to life-threatening reactions.
Common symptoms include hives, itching, and swelling, especially around the face, lips, mouth, or throat. Many people also experience digestive problems such as stomach pain, nausea, or vomiting. In more serious cases, food allergies can affect breathing, causing airway swelling, shortness of breath, or difficulty swallowing. Some reactions may cause a sudden drop in blood pressure, making a person feel dizzy or faint.
The most severe reaction is called anaphylaxis. It can develop quickly and may block the airways or cause a drastic decline in blood pressure. Anaphylaxis is a medical emergency that requires immediate treatment.
Because food allergies can be unpredictable, people with known allergies should avoid trigger foods and seek medical care immediately if severe symptoms occur.
