Hello, If you are allergic to certain ingredients of the food you are eating you might develop severe allergic reaction to it and in some cases it might cause swelling in the throat and be life threatening. it seems similar to asthma attack but it is called anaphylaxis. It might also cause swelling on the lips or the eyes together with the shortness of breath and cough. You might need to see your doctor and probably have some allergy tests to try to identify the offending agent and try to avoid its use. Try to avoid using food that you are not sure of the ingredients as well. I hope I have answered to your query. Let me know if I can assist you further. Take care Regards, Antoneta Zotaj, General & Family Physician
