An intolerance to eggs is different from an egg allergy. Though egg allergies are not nearly as common as egg intolerance it still does occur. Egg allergies are more likely to occur in children. An allergy is an immune response with symptoms such as mild hives and breathing issues to severe life-threatening anaphylactic shock. An intolerance can manifest in many different ways.
If other gastrointestinal issues have been ruled out and a person suffers symptoms such as nausea, vomiting, bloating, flatulence, diarrhea, constipation and cramping after eating certain foods or foods containing certain ingredients, then an intolerance should be highly suspected.
Each of us becomes acutely aware of patterns occurring in our health. If there ever is a thought that eggs are causing the symptoms of food intolerance, it should be considered and explored.
It is also important to mention that with egg intolerance, one could be intolerant to just the egg yolk, just the egg white or both the yolk and the whites.
