Levels of Allergy
Allergies are an overreaction of the immune system to a foreign substance, typically resulting in a variety of physical reactions. Allergy reactions can range from mild to severe, and can even be life-threatening. The four levels of allergy reactions are mild, moderate, severe, and anaphylaxis.
Mild
Mild allergies are the most common and least serious. Symptoms can include itching, redness, swelling, and hives. These reactions can usually be treated with over-the-counter antihistamines.
Moderate
Moderate allergies are more serious and can cause a range of symptoms, including difficulty breathing, chest tightness, and swelling of the tongue, lips, or throat. These reactions may require medical attention or an injection of epinephrine.
Severe
Severe allergies can cause anaphylaxis, a potentially life-threatening reaction that can cause swelling of the airways and difficulty breathing. Anaphylaxis requires immediate medical attention and an injection of epinephrine.
Anaphylaxis
Anaphylaxis is a severe and potentially life-threatening reaction that can occur within minutes of exposure to an allergen. Symptoms can include difficulty breathing, swelling of the tongue or throat, and a drop in blood pressure. Anaphylaxis requires immediate medical attention and an injection of epinephrine.
