Acute urticaria, also known as hives, is a common skin condition that causes itchy, red welts to appear on the skin. These welts can range in size and may come and go quickly. In this article, we’ll provide simple explanations for various aspects of acute urticaria, including its types, causes, symptoms, diagnostic tests, treatments, and drugs.
Types of Acute Urticaria:
Acute urticaria can be categorized into two main types:
- Spontaneous Acute Urticaria: This type occurs suddenly without any identifiable cause. It can be triggered by various factors such as stress, infections, or medications.
- Inducible Acute Urticaria: This type is caused by specific triggers like temperature changes, pressure on the skin, or exposure to certain substances. It often appears in response to these triggers.
Causes of Acute Urticaria
- Allergies: Allergic reactions to foods, medications, insect stings, or pollen can lead to hives.
- Infections: Viral or bacterial infections, like the common cold or urinary tract infections, may trigger acute urticaria.
- Medications: Some drugs, such as antibiotics or painkillers, can cause hives as a side effect.
- Stress: Emotional stress can lead to hives in some individuals.
- Insect Bites: Bee stings, mosquito bites, or tick bites can result in hives.

- Hormonal Changes: Hormonal fluctuations during pregnancy or menstruation can trigger hives in some women.
- Food Additives: Certain food additives, such as preservatives or colorings, may cause hives in susceptible individuals.
- Allergic Reactions to Insect Venom: Severe allergic reactions to bee or wasp stings can result in hives.
- Environmental Factors: Pollutants or irritants in the environment can contribute to urticaria.
- Fungal Infections: Some fungal infections can lead to skin hives.
- Dental Problems: Oral infections or dental work may cause hives in rare cases.
- Genetic Factors: A family history of urticaria can increase the risk of developing the condition.
- Idiopathic: In many cases, the exact cause of acute urticaria remains unknown, and it is termed idiopathic.
Symptoms of Acute Urticaria
