My tongue swells every time i eat salty food (i.e.-french fries). should i be concerned?

Avoid salt: There is no easy answer here, could this be an allergic reaction? Hard to say. The salt could cause a histimine release and cause the tongue to swell. I would stay away from processed foods and switch to a low salt more natural diet.

Probably not.: Salt, spices and acids such as citrus fruits can cause the tongue to swell. As long as it is mild swelling and not making breathing a problem, you probably have nothing to worry about. You may wish to avoid too much salt so the problem won't occur often.
