Causes, Symptoms, and How DoctorTora Can Help

Introduction

Urticaria, commonly known as hives, is a skin condition that causes itchy, raised welts on the skin. These red or skin-colored bumps can appear suddenly and disappear within hours or persist for longer periods. Urticaria can be triggered by allergens, stress, infections, or environmental factors. While most cases of urticaria are harmless, persistent or severe cases may require medical attention. If you are experiencing hives, DoctorTora’s telemedicine services can connect you with a doctor quickly and conveniently from the comfort of your home.

What is Urticaria?

Urticaria, also referred to as hives, is a skin reaction that leads to swollen, red, or pale welts that can vary in size and shape. The condition can be classified into:

• Acute urticaria – Lasts for less than six weeks and is often triggered by allergens, medications, or infections.
• Chronic urticaria – Lasts longer than six weeks and may not have an identifiable cause.
• Physical urticaria – Triggered by external stimuli such as heat, cold, pressure, or sunlight.

Other common names for urticaria include:

• Hives
• Wheals
• Angioedema (when deeper layers of the skin are affected)
• Allergic rash

Common Symptoms and Causes of Urticaria

Symptoms:

• Raised, red or skin-colored welts on the skin
• Intense itching or burning sensation
• Welts that change shape and size, merging or spreading
• Skin swelling (angioedema) in severe cases, affecting the lips, eyelids, and throat
• Symptoms that come and go within hours or last for weeks in chronic cases

Causes:

Urticaria occurs when the immune system releases histamine and other chemicals in response to a trigger. Common triggers include:

• Allergic reactions – Foods (nuts, seafood, dairy), medications, pollen, insect bites
• Infections – Viral or bacterial infections, including colds and flu
• Environmental factors – Heat, cold, sun exposure, pressure on the skin
• Stress and emotional triggers – Anxiety, physical exertion
• Certain medications – Pain relievers, antibiotics, and anti-inflammatory drugs
• Underlying medical conditions – Autoimmune disorders or thyroid disease

How is Urticaria Diagnosed?

A doctor can diagnose urticaria based on a physical examination and a discussion of symptoms and potential triggers. In some cases, allergy tests, blood tests, or skin biopsies may be conducted to determine the underlying cause.

How is Urticaria Treated?

Treatment for urticaria depends on the severity and duration of the condition. Mild cases often resolve on their own, while persistent or severe cases may require medication.

Common Medications:

• Antihistamines – Help reduce itching and swelling (e.g., loratadine, cetirizine, fexofenadine)
• Corticosteroids – Prescribed for severe cases to reduce inflammation
• Epinephrine (adrenaline) – Used in emergency cases of severe allergic reactions (anaphylaxis)
• Immunosuppressants – For chronic urticaria that does not respond to standard treatments

Self-Care Instructions for Urticaria

Self-care and lifestyle adjustments can help manage urticaria and prevent flare-ups. Here are some key tips:

• Avoid known triggers such as allergens, heat, or certain foods.
• Wear loose-fitting, breathable clothing to prevent irritation.
• Apply cool compresses to soothe itchy areas.
• Take lukewarm baths with oatmeal or baking soda to reduce discomfort.
• Use fragrance-free skincare products to avoid skin irritation.
• Practice stress management techniques such as meditation or yoga.
• Keep a symptom diary to identify patterns and potential triggers.
