Acute and chronic urticaria are two forms of skin reactions characterized by raised welts or hives. Understanding their differences helps in effective management.
Q: What is acute urticaria?
A: Acute urticaria is a transient skin condition that lasts less than 6 weeks. It often results from allergic reactions to foods, medications, or insect stings.
Q: What is chronic urticaria?
A: Chronic urticaria lasts more than 6 weeks and can persist for months or even years. It may have various underlying causes, often idiopathic.
Differences Between Acute and Chronic Urticaria
| Feature | Acute Urticaria | Chronic Urticaria |

| Common Triggers | Foods, medications, insect stings | Often unknown; may include stress, infections |
| Frequency of Episodes | Generally one-time or infrequent | Recurring episodes over time |
| Treatment Duration | Short-term antihistamines | Long-term management strategies |
| Diagnosis | Often clinical history & physical exam | May require additional tests (e.g., blood tests) |

- Red or skin-colored swellings
- Possible angioedema (swelling beneath the skin)
Treatment Approaches
- Antihistamines (for both forms)
- Oral corticosteroids (in cases of severe symptoms)
- Avoidance of known triggers
- Immunotherapy (in chronic cases)
Statistics
| Type of Urticaria | Prevalence (%) |
|---|---|
| Acute Urticaria | 20-25% |
| Chronic Urticaria | 0.5-5% |
Mind Map of Urticaria Types
- Urticaria
- Acute Urticaria

Conclusion
Understanding the differences between acute and chronic urticaria is essential for diagnosing and managing this condition effectively. While acute urticaria typically resolves quickly with appropriate treatment, chronic urticaria requires ongoing management strategies to control symptoms and improve quality of life.
