Hives: A Comprehensive Guide


Hives, also known as urticaria, is a common skin condition characterized by raised, itchy welts that can appear anywhere on the body. These welts typically develop within minutes of exposure to a trigger and can last for hours or even days. Hives can range in size from small dots to large patches, and they can vary in color from pink to red.


The most common symptom of hives is the development of raised, itchy welts. These welts are typically round or oval and can range in size from a few millimeters to several centimeters. The welts can be pink, red, or white, and they may have a pale center.

Other symptoms of hives may include:

  • Swelling of the lips, tongue, or eyelids
  • Difficulty breathing
  • Dizziness
  • Nausea
  • Vomiting
  • Abdominal pain
  • Diarrhea


Hives can be caused by a variety of triggers, including:

  • Allergic reactions: Hives are often caused by allergic reactions to foods, medications, insect bites, or other allergens.
  • Non-allergic triggers: Hives can also be triggered by non-allergic factors, such as stress, heat, cold, or sunlight.
  • Medical conditions: Some medical conditions, such as autoimmune disorders and infections, can also cause hives.


Hives are typically diagnosed based on a physical examination and a medical history. Your doctor will ask you about your symptoms, when they started, and what you think may have triggered them. Your doctor may also perform a skin prick test to identify specific allergens that may be causing your hives.


The treatment for hives depends on the underlying cause. If the hives are caused by an allergic reaction, your doctor may recommend avoiding the allergen and taking antihistamines to relieve the symptoms. If the hives are caused by a non-allergic trigger, your doctor may recommend avoiding the trigger and taking over-the-counter medications, such as ibuprofen or acetaminophen, to relieve the symptoms.

In some cases, your doctor may prescribe stronger medications, such as corticosteroids or immunosuppressants, to treat hives.


The prognosis for hives is generally good. Most cases of hives resolve within a few days or weeks. However, some people may experience chronic hives, which can last for months or even years.


There is no surefire way to prevent hives, but there are some things you can do to reduce your risk of developing them. These include:

  • Avoiding known allergens
  • Managing stress
  • Avoiding extreme temperatures
  • Wearing loose-fitting, breathable clothing
  • Taking cool baths or showers
  • Using mild soaps and detergents


Hives are a common skin condition that can be caused by a variety of triggers. The symptoms of hives can range from mild to severe, and the condition can be acute or chronic. Treatment for hives depends on the underlying cause, and the prognosis is generally good.
