The four stages of anaphylaxis are Mild anaphylaxis, Moderate anaphylaxis, Severe anaphylaxis and life threatening anaphylaxis.
Mild anaphylaxis is stage 1 anaphylaxis and includes the early warning signs of anaphylaxis which include:
Skin reactions, which include localized redness, itching, flushed skin, or early hives also known as (urticaria).
Mucosal signs, which include a mild tingling sensation in or around your mouth and throat.
And status, which may resemble a basic, non severe allergic reaction, which makes it easy to miss.
Moderate anaphylaxis, which is stage 2 anaphylaxis (Systemic Progression), involves spreading symptoms like hives and rashes that spread more widely across your body.
And swelling, which includes mild swelling that begins in your lips, tongue, eyes or soft palate.
And digestive involvement which includes the onset of abdominal cramps, nausea, vomiting, or diarrhea as multiple body systems react.
Severe anaphylaxis which is also (Anaphylactic Shock) causes respiratory distress, which includes significant difficulty breathing, wheezing, throat tightness or even coughing.
Cardiovascular impact, which includes a weak, rapid pulse, dizziness, or lightheadedness.
And status, in which the body enters a state of anaphylactic shock where your blood pressure drops dangerously low, depriving your vital organs of blood flow.
And stage 4 anaphylaxis which is life threatening anaphylaxis, which is also a critical emergency.
In stage 4 anaphylaxis, it leads to cardiorespiratory arrest, where breathing may stop completely, also known as respiratory arrest and blood circulation can also fail, which is also known as a circulatory arrest/heart attack0.
Unconsciousness, in which you lose consciousness and experience profound oxygen deprivation to the brain and vital organs.
In stage 4 anaphylaxis, it's a fatal medical emergency that requires immediate administration of epinephrine and emergency intervention.
If you or someone else experiences signs of stage 3 or stage 4 anaphylaxis, call 911 or your local emergency number immediately and if you have one use an auto-injector (epinephrine).
