When people get hives or swelling, they often think it’s caused by an allergy. But in the case of chronic spontaneous urticaria (CSU), the culprit is often your own immune system. CSU isn’t your typical allergic reaction, instead, it’s frequently an autoimmune condition, where the immune system misfires and activates mast cells without any external trigger.

In this episode, Dr. Payel Gupta and Kortney unpack what it means for CSU to be autoimmune and autoallergic. They explain how IgE and IgG antibodies can trigger histamine release, leading to hives and swelling. You’ll also learn why allergy testing isn’t useful for diagnosing CSU, and how tests like IgG food sensitivity panels can do more harm than good by leading to unnecessary food avoidance and confusion.
