Signs of Anaphylactic Shock
In rare cases allergic reactions may be so severe, they lead to anaphylactic shock (anaphylaxis). This is a severe and sometimes fatal reaction to a foreign substance the body is allergic to. Anaphylactic shock usually develops within minutes of exposure to the allergen and can progress rapidly, affecting the whole body.
People experiencing anaphylaxis [6] may experience difficulty breathing, lightheadedness, confusion or loss of consciousness. They may develop blueish skin or lips and inflammation of the throat and mouth. Anaphylaxis is a medical emergency and should be treated immediately.
If you carry emergency epinephrine, you should give yourself a shot to counter serious reactions while you wait for help.
Conclusion
Allergies are common and aren’t life-threatening most of the time. Most allergies can be helped through medication while some may fade with time. The most effective way to avoid allergies is to learn what your triggers are and stay away from them. If you’re at risk of anaphylactic shock, you should see a doctor who can help you plan how to manage your allergies and prevent complications.
