A member asked:

Could allergies make someone feel dizzy and almost faint?

A doctor has provided 1 answer
Dr. Mark Loury answered

Specializes in ENT and Head and Neck Surgery

Not likely: Regular pollen or food allergies wouldn't normally cause these symptoms. Severe allergic reactions such as anaphylaxis can drop blood pressure with lightheadedness, syncope, severe blood pressure drop, shortness of breath.
