Introduction
Common allergies triggered by exposure to pollen, dust mites, or certain foods typically cause symptoms localized to the skin, respiratory tract, or digestive system. These may include skin redness, itching, sneezing, and nausea. Symptoms are usually mild and confined, do not affect the central nervous system, and never lead to coma. Prompt removal from the allergen and appropriate symptomatic treatment generally result in rapid relief.
Generally, common allergies often manifest as symptoms such as skin itching and rashes, which typically do not lead to unconsciousness. However, in severe allergic reactions leading to anaphylactic shock, coma may occur rapidly. If there are any concerns, it is recommended to seek medical advice promptly. Detailed analysis is as follows:
Common allergies triggered by pollen, dust mites, or certain foods usually affect the skin, respiratory system, or digestive tract. Symptoms include skin redness, itching, sneezing, nausea, etc. These symptoms are generally mild and localized, do not affect the central nervous system, and will not cause coma. Symptoms can be quickly relieved by promptly removing exposure to the allergen and receiving appropriate symptomatic treatment.
When exposed to strong allergens such as penicillin or certain insect venoms, severe anaphylactic shock may develop rapidly. Sudden blood vessel dilation leads to a sharp drop in blood pressure, resulting in insufficient blood flow and oxygen supply to the brain. This may be accompanied by laryngeal edema and breathing difficulties, quickly progressing to dizziness, confusion, and ultimately coma. This condition is a medical emergency requiring immediate first aid measures.
In daily life, individuals should pay attention to their allergy history and avoid known allergens. Prompt medical attention should be sought when allergic symptoms appear to prevent delays in treatment.
