Autoimmune Hives: Causes, Symptoms, Treatments, and More - Healthline
Hives are itchy red welts which can erupt without warning. They're rarely dangerous but can be uncomfortable, especially if they recur often. Hives that last for 6 weeks or longer are considered chronic. Some people may have hives for years. It can be challenging to figure out what triggers these itchy occurrences, although allergens can sometimes be a cause. When the reason for hives remains unknown, they're said to be idiopathic. Around 30 to 40 percent of the time, idiopathic hives are triggered by the body's own immune system. These hives are autoimmune in nature and are known as autoimmune urticaria (hives). Autoimmune hives erupt when the body's immune system is overactive and attacks the body's normal cells and tissues. Autoimmune hives may be a stand-alone symptom with no obvious underlying cause. They may also occur in conjunction with diagnosable autoimmune conditions. It is possible to have more than one autoimmune condition at the same time
