Final answer:
The statement that a person having an allergic reaction is in no danger and will not require medical attention is false. Allergic reactions, especially severe ones like anaphylaxis, can be life-threatening. Immediate medical attention and the use of epinephrine can be crucial for survival.
Step-by-step explanation:
False. A person who is having an allergic reaction may be in serious danger and could require immediate medical attention. Allergic reactions can range from mild to severe. In the case of a severe allergic reaction, known as anaphylaxis, the immune system releases a large amount of chemicals that can cause the body to go into shock. Symptoms can include rapid swelling of tissues which can lead to difficulty in breathing, a drop in blood pressure, and loss of consciousness. If not treated quickly, anaphylaxis can be life-threatening.
An allergy indeed results when the immune system overreacts to a harmless substance, such as pollen, dust, or certain foods. This reaction can cause unpleasant symptoms such as watery, itchy eyes, swollen tissues, and sneezing. In more severe cases, it could progress to anaphylaxis.
Therefore, it is crucial to take allergies seriously. People who are known to have severe allergic reactions often carry epinephrine auto-injectors (EpiPens) and should use them at the first sign of a serious allergic reaction. Medical attention should be sought immediately after using an epinephrine auto-injector or if any signs of anaphylaxis are observed.
