Introduction
The primary distinction between acute and chronic urticaria lies in the duration of the disease. Acute urticaria is typically sudden in onset and usually transient, often resolving within 3–5 days of treatment. In contrast, chronic urticaria—and associated erythema multiforme—recurs repeatedly and persists for more than six weeks. Acute urticaria presents more abruptly, with sudden onset of skin rash, possibly accompanied by fever; in severe cases, patients may experience chest tightness, shortness of breath, dizziness, and other symptoms.
Urticaria (hives) is relatively common in daily life; however, few people truly understand its symptoms in depth. Many are unaware that urticaria can be classified as either acute or chronic—leading some to miss the optimal window for treatment and potentially causing greater harm to their health. So, what are the key differences between acute and chronic urticaria?
Differences Between Acute and Chronic Urticaria
The primary distinction between acute and chronic urticaria lies in disease duration. Acute urticaria typically has a sudden onset and is usually transient, often resolving within 3–5 days of appropriate medication. In contrast, chronic urticaria—and associated erythematous rashes—recur repeatedly and persist for more than six weeks. Acute urticaria tends to be more severe: skin eruptions appear abruptly and may be accompanied by fever; in severe cases, patients may experience chest tightness, shortness of breath, or dizziness. Chronic urticaria, however, generally manifests only as skin erythema, wheals (raised, itchy welts), and pruritus (itching).
Patients with urticaria are advised to avoid alcohol and limit consumption of seafood to help alleviate symptoms. They should also avoid spicy, irritating foods such as chili peppers and garlic, which may exacerbate the condition. Foods like lamb, beef, and dairy products (e.g., milk) may worsen urticarial symptoms in some individuals; however, if no significant deterioration occurs after consuming these foods, they may be continued in the diet. If symptoms persist despite eliminating these potential triggers, pharmacologic treatment for urticaria becomes necessary.
Individuals experiencing symptoms of urticaria should seek timely medical evaluation and treatment to prevent disease progression. We hope this information proves helpful.
