The symptoms of systemic allergy are diverse and may involve multiple systems. Common skin manifestations include erythema, papules, urticaria, pruritus, and even vesicles and erosion. Respiratory symptoms may include coughing, dyspnea, chest tightness, and, in severe cases, laryngeal edema. Gastrointestinal symptoms can present as abdominal pain, diarrhea, nausea, and vomiting. Additionally, systemic allergic reactions may cause systemic symptoms such as tachycardia and arrhythmia. Because systemic allergies can be triggered by various underlying conditions, symptom presentation may differ accordingly. Therefore, if symptoms suggestive of a systemic allergy occur, immediate medical attention should be sought, and treatment should be administered under the guidance of a physician.
