Can hives be a sign of something serious?
Hives appear as a rapidly spreading, red, raised and itchy rash in splotches or all over the body. Caused by an allergic reaction to medications or food, hives can be a sign of a life-threatening problem when accompanied by difficulty breathing and a drop in blood pressure.
Can hives be a sign of autoimmune disease?
Chronic Autoimmune Illnesses Linked to Chronic Hives. Sometimes a hidden illness may be an underlying cause. Studies have found a strong association between chronic hives and autoimmune diseases such as thyroid disease, rheumatoid arthritis, celiac disease, type 1 diabetes, Sjögren syndrome, and lupus.
What autoimmune diseases cause rashes?
Rashes can be seen in many of the diseases we treat including scleroderma, vasculitis, lupus and dermatomyositis. Many physicians and patients are aware of the classic malar (over cheeks and nose) rash seen in systemic lupus erythematosus (SLE or lupus) that can be triggered by exposure to sunlight.
Why am I getting hives all of a sudden?
A sudden onset of hives (acute hives) usually has an identifiable cause or trigger — such as insect stings or bites, medications, certain foods, allergens, or infections. Acute hives go away within a few weeks and are usually effectively treated with antihistamines. Chronic hives can go on for months and even years.
