Hives: Causes, Symptoms, and Treatment Options
Hives, also known as urticaria, are a common skin condition characterized by itchy, raised welts. These welts can grow larger, change shape, and spread, disappearing and reappearing over time. They are typically caused by allergic reactions or underlying health issues, and can affect people of all skin tones.
Hives are usually red, pink, or flesh colored, but can also be the same color as your skin. They can be triggered by a wide range of factors, including allergens like foods, pet dander, pollen, and medications, as well as stress, tight clothes, exercise, illnesses, infections, or temperature changes. In some cases, the cause may not be identifiable.
Allergic reactions are the most common cause of hives. These reactions can range from mild to severe, with anaphylaxis being a life-threatening emergency that can cause hives along with breathing difficulties, nausea, severe swelling, and dizziness. Individual hives welts can last from a few minutes to several days.
Chronic hives, or chronic urticaria, are ongoing cases that can last from weeks to several months or years. These can be a symptom of an autoimmune disorder or other health conditions. While there are no general statistics on the frequency of hives in people with autoimmune diseases, the occurrence seems to depend on the type of autoimmune disease and individual predisposition.
Hives are a common and treatable skin condition, but they can be uncomfortable and distressing. If you suspect an allergic reaction, it's important to seek medical attention. If you have chronic hives, it's crucial to work with a healthcare provider to manage the condition and identify any underlying causes.
