Urticaria, commonly known as hives, is a skin condition characterized by the sudden appearance of raised, red, itchy welts or bumps on the skin. These welts can vary in size and shape and often appear and disappear within a few hours. They can occur anywhere on the body and may change shape, fade, and reappear in different areas.Best Skin Clinic in Varanasi
Urticaria can be categorized into two main types:
- Acute Urticaria: This type of urticaria typically lasts for less than six weeks and is often caused by an allergic reaction to certain foods, medications, insect stings, or other allergens. It can also be triggered by non-allergic factors such as infections, stress, or exposure to heat or cold.
- Chronic Urticaria: Chronic urticaria lasts for more than six weeks and can persist for months or even years. The exact cause of chronic urticaria is often unknown, but it may be related to autoimmune disorders, hormonal imbalances, or other underlying health conditions.Best Skin Clinic in Varanasi
The underlying mechanism of urticaria involves the release of histamine and other chemicals from mast cells in the skin, leading to inflammation, swelling, and itching. Factors that can trigger this release include allergens, physical pressure on the skin (such as scratching or rubbing), temperature changes, and stress.Best Skin Clinic in Varanasi
Treatment for urticaria typically involves identifying and avoiding triggers, using antihistamines or other medications to relieve symptoms, and managing underlying health conditions if present. In severe cases, corticosteroids or other immunosuppressive medications may be prescribed to control inflammation. Best Skin Clinic in Varanasi
Overall, while urticaria can be uncomfortable and distressing, it is usually not life-threatening and can often be managed effectively with proper treatment and lifestyle modifications. However, individuals with severe or persistent symptoms should consult a healthcare professional for diagnosis and management.Best Skin Clinic in Varanasi
