What is Urticaria?

Urticaria, commonly known as hives, is a skin condition that affects millions of people worldwide. It can be uncomfortable and frustrating, but with the right information, you can manage it effectively. In this article, we will break down urticaria into simple terms, discussing its types, causes, symptoms, diagnostic tests, treatments, and drugs.

Urticaria, also called hives, is a skin condition characterized by raised, itchy, and often red welts on the skin. These welts, or wheals, can vary in size and shape and may appear suddenly and disappear within hours. Urticaria can affect any part of the body and can be either acute or chronic.

Types of Urticaria

1. Acute Urticaria: This type lasts for a short period, typically less than six weeks, and is often caused by allergies to certain foods, medications, or insect stings.
2. Chronic Urticaria: Chronic urticaria persists for more than six weeks and can be more challenging to pinpoint the exact cause. It may be linked to underlying health issues or autoimmune conditions.

Common Causes of Urticaria

1. Allergies: Exposure to allergens like pollen, pet dander, or certain foods can trigger urticaria in susceptible individuals.
2. Medications: Some drugs, such as antibiotics, painkillers, and blood pressure medications, can lead to hives as a side effect.
3. Insect Bites and Stings: Bee stings, mosquito bites, or ant bites can cause hives in some people.
4. Food Allergies: Foods like nuts, shellfish, and eggs can trigger urticaria in those with allergies.

9. Autoimmune Disorders: Conditions like lupus and thyroid disorders may be associated with chronic urticaria.
10. Hormonal Changes: Hormonal fluctuations, especially in women during menstruation, pregnancy, or menopause, can lead to hives.
11. Chemical Exposures: Contact with certain chemicals or additives can trigger urticaria in sensitive individuals.
12. Inflammation: Chronic inflammation in the body may contribute to chronic urticaria.
13. Genetics: A family history of urticaria may increase the risk of developing the condition.
14. Chronic Illness: Underlying chronic diseases like diabetes or hepatitis can be linked to chronic urticaria.
15. Underlying Allergic Conditions: Individuals with asthma, hay fever, or other allergies may be more prone to urticaria.

17. Pregnancy: Some pregnant women experience urticaria due to hormonal changes.
18. Certain Foods: Spicy foods and alcohol can exacerbate urticaria in some individuals.
19. Scratching: Persistent scratching of the skin can lead to urticaria, known as dermatographism.
20. Idiopathic: In many cases, the exact cause of urticaria remains unknown, termed idiopathic urticaria.

Common Symptoms of Urticaria

1. Raised Red Welts: The hallmark symptom of urticaria is the appearance of itchy red welts on the skin.
2. Itching: The welts are typically accompanied by intense itching.

9. Flares and Remissions: Urticaria symptoms can come and go, with flares and periods of remission.
10. Localized or Generalized: Hives can be limited to one area or spread across the body.
11. Resolving Quickly: Acute urticaria lesions usually resolve within 24 hours.
12. Lasting Longer: In chronic urticaria, lesions may persist for days or even weeks.
13. Fatigue: Chronic urticaria can cause fatigue due to sleep disturbances caused by itching.
14. Mood Disturbances: Living with chronic urticaria can lead to mood changes and anxiety.

16. Swollen Tongue or Throat: Swelling of the tongue or throat can be life-threatening and needs emergency care.
17. Digestive Symptoms: Some people with urticaria may experience digestive issues, such as nausea and diarrhea.
18. Joint Pain: Joint pain or arthritis-like symptoms can occur in some cases.
19. Fever: Rarely, urticaria can be associated with a fever in systemic reactions.
20. Scarring: Chronic scratching can lead to scarring and changes in skin texture.

Diagnostic Tests for Urticaria

1. Physical Examination: A doctor can often diagnose urticaria based on the appearance of the welts.
2. Medical History: Discussing your symptoms and possible triggers helps in diagnosis.
3. Allergy Testing: Skin tests or blood tests can identify specific allergens triggering urticaria.
4. Patch Testing: Patch tests can determine if contact with specific substances is causing hives.
5. Thyroid Function Tests: Thyroid disorders are sometimes associated with chronic urticaria.
6. Complete Blood Count (CBC): This test helps rule out infections as a cause.
7. Erythrocyte Sedimentation Rate (ESR): Elevated ESR may indicate inflammation.
8. C-Reactive Protein (CRP): Elevated CRP levels can suggest underlying inflammation.

18. Blood Pressure Monitoring: Important when angioedema affects the throat or airways.
19. Skin Prick Testing: To identify allergens triggering urticaria in some cases.
20. Drug Challenge Tests: In suspected medication-induced urticaria, controlled drug challenges can be performed under medical supervision.
