A severe allergic reaction can be life-threatening and requires immediate medical attention. It is important to know the signs and symptoms of a severe allergic reaction (anaphylaxis) so that you can get the appropriate treatment.
Signs and Symptoms of a Severe Allergic Reaction
The most common signs and symptoms of a severe allergic reaction can include:
Hives: Hives are raised, red welts on the skin that can range in size and usually itch.
Swelling: Swelling of the face, lips, tongue, throat, or other parts of the body can occur.
Wheezing: Wheezing is a whistling noise made when breathing, usually due to narrowing of the airways.
Difficulty Breathing: Difficulty breathing can occur due to swelling in the throat or wheezing.
Decreased Blood Pressure: A drop in blood pressure can occur, leading to dizziness, lightheadedness, or loss of consciousness.
Nausea and Vomiting: Nausea and vomiting can occur due to a reaction to certain foods or medications.
If you experience any of these symptoms, seek medical attention immediately. It is important to note that not all allergic reactions are severe, but it is important to be aware of the signs and symptoms of a severe allergic reaction.
