Hives represent a skin response characterized by itchy welts, also known as wheals. When these welts persist for over six weeks and recur frequently over extended periods, they are referred to as chronic hives. The underlying cause of this condition often remains unclear.
Typically, the welts begin as itchy patches that transform into swollen welts of varying sizes. These welts emerge and vanish unpredictably as the reaction progresses.
Chronic hives can lead to significant discomfort, disrupting normal sleep and daily routines. For many individuals, relief is attainable through the use of anti–itch medications, such as antihistamines.

The reasons behind chronic hives’ occurrence and the transition from short–term to long–term hives often remain elusive.
The skin’s reactive response can be triggered by various factors, including:
Approximately 20% of individuals experiencing chronic hives are simultaneously affected by autoimmune disorders, which encompass conditions like celiac disease, dermatomyositis, diabetes, lupus, polymyositis, rheumatoid arthritis, thyroid disease, and vitiligo.
