Anaphylaxis Symptoms
Reviewed: Dr. Mera
5. Cardiovascular Problems
Anaphylaxis can lead to cardiac and vascular symptoms, including a severe decrease in blood pressure that may lead to lightheadedness. Allergic reactions produce certain chemicals, which flood the bloodstream causing blood vessels to expand. This leads to a severe decrease in blood pressure and dizziness.
Your heart starts beating faster in order to compensate for this drop in blood pressure. If you have a heart problem, the condition can be more severe, leading to a heart spasm where one of the coronary arteries becomes narrower. This can cause severe chest pain.
