Yes, it is possible to have non-respiratory allergic reactions such as eczema, eye itching, and abdominal discomfort with certain foods like wheat. Food allergies occur when the immune system reacts to a protein in the food, and the reaction can manifest in various ways. Some common symptoms of food allergies include itching and irritation in the mouth, hives or skin redness, stomach pain, vomiting, or diarrhea. More severe allergic reactions may involve difficulty breathing, swallowing, or speaking, coughing, hoarse voice, and a drop in blood pressure along with weakness, loss of consciousness, or confusion. If you suspect a food allergy, it is important to consult with your family doctor or pediatrician who can refer you to an allergist for further evaluation and testing.
