What Are Hives?
Hives, also known as urticaria, is a skin condition characterized by itchy, raised, red welts on the skin that can range in size from a few millimeters to several centimeters. Hives typically appear suddenly and can last anywhere from a few minutes to several days. They may come and go in different areas of the body over the course of several hours or days.
Common Causes of Hives
Hives can be caused by a variety of different triggers, including allergies, medications, insect stings, infections, and physical factors. Allergies are the most common cause of hives, but many other factors can also trigger hives. Some of the most common causes of hives include:
• Allergies to foods, medications, or other substances
• Insect stings
• Physical factors such as pressure, temperature, or water
• Infections such as viruses or bacteria
• Emotional stress
• Exposure to sunlight
• Autoimmune disorders
Treating Hives
The treatment for hives depends on the underlying cause. If the hives are caused by an allergy, the person should avoid the allergen that is triggering the hives. Some medications, such as antihistamines or corticosteroids, may be prescribed to reduce the itching and swelling associated with hives. In some cases, ultraviolet light treatments or immunotherapy may be recommended.
If the hives are persistent and do not go away on their own, it is important to see a doctor to determine the underlying cause. A doctor can help diagnose the cause of the hives and develop a treatment plan to help reduce the symptoms and prevent further outbreaks.
