Egg yolk intolerance may be characterized by nausea, vomiting, and abdominal pain. Intolerance to egg yolks is usually caused by an allergy to one of the ingredients in egg yolks. Patients who are allergic to egg yolks may then react with nausea and vomiting after consumption. Some patients with food allergies may also experience throat discomfort, rashes, and itchy skin. In severe cases, it may also cause allergic enteritis. Patients with allergic enteritis may experience diarrhea, abdominal pain, blood in the stools, generalized edema and other symptoms. Patients with severe allergies may also experience anaphylaxis, acute asthma, laryngeal edema and other emergencies. If egg yolk intolerance occurs, patients are advised to visit the gastroenterology department of the hospital to identify the cause and treat it.
