Many different diseases and conditions can cause hives (urticaria), a common skin reaction characterized by itchy, raised welts. It's not caused by a single disease, but rather a variety of underlying issues trigger the body's immune system to produce hives.
Causes of Hives
Several conditions can lead to the development of hives. These include:
-
Infections: Bacterial infections like H. pylori (which can cause stomach ulcers) and sinus infections (sinusitis) can trigger hives. Viral infections are also a common cause.
-
Liver Disease: Problems with the liver can sometimes manifest as hives.
-
Autoimmune Diseases: Conditions where the body's immune system attacks its own tissues, such as certain lymphomas (Hodgkin lymphoma and non-Hodgkin's lymphoma), can be associated with hive formation. Vasculitis, an inflammation of blood vessels, is another example.
-
Other Allergic Reactions: While not a disease itself, allergic reactions to foods, medications, insect bites/stings, or environmental factors frequently result in hives.
It's important to note that this is not an exhaustive list, and other factors can contribute to hive development. A doctor can properly diagnose the underlying cause of hives based on symptoms and medical history.
