Corn allergy

Corn allergy is a type of food allergy where an individual's immune system reacts abnormally to corn and corn products. This reaction can range from mild to severe, and can include symptoms such as skin rashes, stomach cramps, vomiting, and in severe cases, anaphylaxis.

Symptoms

The symptoms of corn allergy can vary from person to person, and can occur immediately after consumption or can be delayed for several hours. Common symptoms include:

• Skin rash or hives
• Stomach cramps
• Vomiting
• Diarrhea
• Wheezing
• Anaphylaxis (in severe cases)

Causes

Corn allergy is caused by an abnormal immune response to the proteins found in corn. The immune system mistakenly identifies these proteins as harmful and releases chemicals to protect the body, causing allergic symptoms.

Diagnosis

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

Treatment

There is currently no cure for corn allergy, and the best way to manage the condition is to avoid consuming corn and corn products. In cases where an allergic reaction occurs, medications such as antihistamines or corticosteroids may be used to alleviate symptoms. In severe cases, emergency treatment with epinephrine may be required.
