Oral Immunotherapy (OIT) is a medical treatment designed to help individuals with food allergies, particularly to peanuts or tree nuts. The process involves gradually introducing small amounts of the allergenic food into the patient's diet. Over time, the dosage is increased, allowing the immune system to build tolerance to the allergen. This therapy aims to reduce the severity of allergic reactions and improve the quality of life for those affected. While OIT can be effective, it is typically conducted under medical supervision due to potential side effects, including allergic reactions during the treatment process.
