Soy Allergy is a type of food allergy that is triggered by the consumption of soy products. It is one of the more common food allergies, especially among babies and children.

Symptoms

The symptoms of a soy allergy can range from mild to severe and can include:

• Hives or skin rash
• Itching in the mouth
• Difficulty breathing
• Abdominal pain
• Diarrhea
• Nausea or vomiting
• Dizziness
• Anaphylaxis

Causes

A soy allergy occurs when the body's immune system mistakenly identifies soy as harmful and creates antibodies against it. When soy is consumed, the immune system releases chemicals such as histamine, which cause allergy symptoms.

Diagnosis

A soy allergy is typically diagnosed through a combination of a patient history, skin prick test, and blood test. In some cases, an oral food challenge may be conducted under medical supervision.

Treatment

The primary treatment for a soy allergy is avoidance of soy products. This can be challenging, as soy is found in many processed foods. In cases of accidental ingestion, antihistamines may be used to relieve symptoms. In severe cases, such as anaphylaxis, emergency treatment with epinephrine is required.
