Subtitle: Overview
Allergies are an overreaction of the immune system to a foreign substance, such as pollen, dust mites, animal dander, or certain foods. Allergic reactions can range from mild to severe, and they can involve a range of symptoms, such as sneezing, itchy eyes, a runny nose, and skin rashes. Allergies are divided into three stages: early, middle, and late.
Subtitle: Early Stage
In the early stage of an allergic reaction, the body’s immune system releases histamine, a chemical that causes the body to have an allergic response. During this stage, the body may experience symptoms such as sneezing, itchy eyes, runny nose, and congestion.
Subtitle: Middle Stage
The middle stage of an allergic reaction occurs when the body is exposed to a higher level of the allergen. During this stage, the body’s immune system releases more histamine, resulting in more severe symptoms, such as hives, coughing, and swelling.
Subtitle: Late Stage
The late stage of an allergic reaction is the most severe. In this stage, the body’s immune system releases a large amount of histamine, which can cause anaphylaxis, a life-threatening reaction that can cause difficulty breathing, a drop in blood pressure, and even death. If anaphylaxis occurs, it is important to seek medical attention immediately.
