Urticaria (Hives)

Best Homeopathic Doctor, Consultant, Clinic Meerut

Urticaria, also known as hives, is a common skin condition that affects up to 20% of the population at some point in their lives. Urticaria is characterized by red, itchy welts on the skin that can range in size from a few millimeters to several centimeters. The welts are usually raised, with a flat or slightly elevated center and a red, swollen border.

Urticaria can be acute or chronic. Acute urticaria typically lasts for less than 6 weeks, while chronic urticaria lasts for more than 6 weeks. Acute urticaria is usually caused by an allergic reaction to a substance, such as food, medication, or insect bites, while chronic urticaria may have multiple causes, including autoimmune disorders and underlying medical conditions.

Symptoms of Urticaria:

The symptoms of urticaria can vary in severity and duration, but typically include:

  • Red, itchy welts on the skin
  • Swelling of the affected area
  • A burning or stinging sensation
  • Blistering of the skin in severe cases
  • Difficulty breathing or swallowing in rare cases

The welts can appear anywhere on the body and may move from one location to another over the course of a few hours. In some cases, the welts may merge to form larger, more extensive areas of swelling and redness.

  • Thyroid disorders
  • Infections, such as hepatitis or HIV
  • Stress or anxiety
  • Underlying medical conditions, such as cancer or chronic kidney disease

Treatment of Urticaria:

Treatment for urticaria usually involves managing the symptoms and identifying and avoiding the triggers. Medications, such as antihistamines, can be used to relieve itching and reduce swelling. In severe cases, corticosteroids or immune modulators may be prescribed.

In addition to medication, there are several lifestyle changes that can help manage the symptoms of urticaria, including:

  • Avoiding known triggers
  • Wearing loose-fitting clothing
  • Avoiding hot showers or baths
  • Keeping the skin moisturized
  • Practicing stress-reducing techniques, such as meditation or yog

In rare cases, urticaria can lead to anaphylaxis, a severe and potentially life-threatening allergic reaction. If you experience difficulty breathing or swallowing, seek immediate medical attention.

Urticaria is a common skin condition that can be caused by a variety of triggers, including allergies, autoimmune disorders, and underlying medical conditions. While the symptoms can be uncomfortable and disruptive, treatment is available to manage the symptoms and identify and avoid the triggers.
