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.
- Contact Dermatitis: Skin contact with allergenic substances, like latex or certain plants, can cause hives.
- Exercise: In rare cases, intense physical activity can lead to exercise-induced urticaria.
- Heat or Cold: Exposure to extreme temperatures may trigger hives in sensitive individuals.
- Pressure: Wearing tight clothing or leaning on a hard surface can cause pressure-induced hives.
- Sunlight: Some people develop hives after exposure to sunlight, a condition known as solar urticaria.
- Alcohol or Spicy Food: Consumption of alcohol or spicy foods can lead to hives in some individuals.
- Autoimmune Disorders: Conditions like lupus or thyroid disease can be associated with urticaria.
- 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
- Itchy Skin: The hallmark symptom of urticaria is intense itching.
- Red or Pink Welts: Raised, red or pink bumps or welts on the skin.
- Variable Sizes: Hives can range in size from small dots to large patches.
- Rapid Onset: Hives often appear suddenly and can spread quickly.
- Swelling: Affected areas may become swollen.
- Burning Sensation: Some individuals experience a burning sensation in the hives.
- Pain or Tenderness: In some cases, hives can be painful or tender to the touch.
- Blanching: Pressing on a hive causes it to turn white, then red again when released.
- Changing Shape: Hives may change shape and move to different areas of the body.
- Migratory Hives: Hives can come and go within hours or days.
- Flaring with Triggers: Inducible urticaria can flare when exposed to specific triggers.
- Facial Swelling: Swelling of the face, lips, or tongue may occur.
- Difficulty Breathing: Severe cases can lead to difficulty breathing, known as angioedema.
- pain in the head or upper neck. সহজ বাংলা: মাথাব্যথা।" data-rx-term="headache" data-rx-definition="Headache means pain in the head or upper neck. সহজ বাংলা: মাথাব্যথা।">Headache: Some people with urticaria experience headaches.
