An upset stomach after eating eggs can be caused by having an allergy to eggs. Common symptoms of an egg allergy include cramps, nausea, vomiting, skin inflammation or hives, nasal congestion, coughing, wheezing and shortness of breath, according to Mayo Clinic. In severe cases, egg allergies can lead to anaphylaxis, which typically causes rapid pulse, constriction of the airways and severe drop in blood pressure.
