Acute Hives: Causes and Symptoms
Acute hives, also known as acute urticaria, are sudden and short-lived episodes of hives that typically last up to six weeks. These hives can appear anywhere on the body and are often accompanied by itching and raised welts. Allergic reactions and viral infections are the two main causes of acute hives.
Allergic reactions occur when the body’s immune system reacts to certain substances known as allergens. Common allergens that can trigger acute hives include foods, medications, and insect venom. When an allergen comes into contact with the body, it stimulates the production of a specific antibody called immunoglobulin E (IgE). The release of IgE leads to an immune response, causing the blood vessels to leak fluid into the skin, resulting in the development of hives.
Viral infections can also trigger acute hives. The body’s immune response to these infections can cause the release of chemicals that lead to the development of hives. Common viral infections associated with acute hives include the common cold, flu, and hepatitis.
Diagnosing acute hives involves reviewing the individual’s medical history, conducting allergy tests, and identifying potential triggers. Allergy tests such as skin tests and blood tests may be performed to help identify specific allergens that may be causing the hives. Identifying the underlying cause of acute hives is important for effective management and prevention.

Chronic Hives: Types and Triggers
Chronic hives, also known as chronic urticaria, are hives that last for more than six weeks. They can be categorized into two types: chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU). Chronic spontaneous urticaria, also known as chronic idiopathic urticaria, occurs without a known trigger. On the other hand, chronic inducible urticaria is caused by physical stimuli or environmental factors.
Physical urticaria is a subset of chronic inducible urticaria and includes conditions such as dermatographism, delayed-pressure urticaria, exercise-induced urticaria, cold urticaria, heat urticaria, solar urticaria, and vibratory urticaria. These types of hives are triggered by physical sensations like pressure, cold, heat, sunlight, or vibration. On the other hand, non-physical urticaria encompasses conditions like cholinergic urticaria, contact urticaria, and aquagenic urticaria, which are triggered by factors other than physical stimuli.
Chronic Hives: Types and Triggers
Chronic hives can have various triggers, and identifying these triggers is crucial for effective management. Triggers for chronic hives can include factors such as allergens, infections, stress, and certain medications. It is important to keep a symptom diary to track potential triggers and avoid them if possible. Lifestyle changes, such as reducing stress levels, practicing good skincare, and wearing loose-fitting clothes, can also help minimize the occurrence of chronic hives.
| Type of Chronic Hives | Trigger |
|---|---|
| Chronic spontaneous urticaria (CSU) | Unknown trigger |
| Chronic inducible urticaria (CIndU) | Physical stimuli or environmental factors |
| Physical urticaria | Pressure, cold, heat, sunlight, vibration |
| Non-physical urticaria | Cholinergic factors, contact with certain substances, exposure to water |
Identifying and understanding the different types of chronic hives and their triggers can help individuals effectively manage and prevent future outbreaks. If you experience chronic hives lasting more than six weeks, it is recommended to seek medical advice for proper diagnosis and management.
