Hi, your face swells when you eat food which clearly indicates you are having allergy with certain food you
eat. Facial swelling is quite common when experiencing an allergic reaction. When you go to the allergist and
find out what you're allergic to, avoiding it and taking proper medications will minimize the swelling.
Allergy may attack severely if allergen taken in large amount. You may have to take steroids and anti
histaminic against prescription. I suggest you to consult physician and find the allergen as early as
possible. Take care and regards.
