The condition that causes itching and tightening of the throat is a food allergy. In cases of food allergies, the immune system mistakenly identifies a harmless substance, often a protein in food, as a threat. This reaction can trigger the release of chemicals like histamine, leading to symptoms such as itching, swelling, and tightening of the throat. Such symptoms can be serious and may indicate an anaphylactic reaction, which requires immediate medical attention.

Food intolerance, on the other hand, typically results in digestive discomfort rather than immune responses and does not usually involve symptoms such as throat tightening. Gastrointestinal issues could lead to symptoms like abdominal pain, cramping, or changes in bowel movements, but do not typically cause throat symptoms. A respiratory infection is more associated with symptoms like coughing, sneezing, and congestion, rather than localized itching and tightening in the throat caused by an allergic reaction.
