An untreated acute allergic reaction can be a life-threatening situation due to airway constriction that may lead to low blood pressure and shock. When an allergic reaction occurs, the body releases chemicals that can cause the airways to narrow, making it difficult to breathe. If the airway becomes severely constricted, it can lead to a lack of oxygen reaching vital organs, resulting in low blood pressure and shock. This can be extremely dangerous and requires immediate medical attention to prevent further complications.
Vomiting and diarrhea causing dehydration are also potential complications of an allergic reaction, but the primary reason for the life-threatening nature of an untreated acute allergic reaction lies in the risk of airway constriction and its subsequent effects on blood pressure and overall shock response. It's crucial to recognize the symptoms of an allergic reaction and seek prompt medical help to prevent any serious consequences.
