Physical Allergy Urticaria:
Definition and Description of Physical Allergy Urticaria:
Physical allergy urticaria, also known as physical urticaria or chronic inducible urticaria, is a type of skin reaction characterized by the appearance of hives (wheals) when specific physical triggers interact with the skin. These triggers can include mechanical pressure, temperature changes, sunlight, water, and other environmental factors. It is a form of chronic urticaria that can be both unpredictable and uncomfortable, often leading to a significant impact on the quality of life for those affected.
Causes of Physical Allergy Urticaria:
The exact cause of physical allergy urticaria varies among individuals. Common external triggers can include:
- Temperature changes (cold or heat)
- Sun exposure (solar urticaria)
- Pressure on the skin (dermatographism)
- Vibration or exercise (exercise-induced urticaria)
Additionally, some cases may be linked to underlying conditions such as autoimmune disorders, infections, or even certain medications. Genetic factors may also play a role, with some individuals having a hereditary tendency for developing urticaria.
Associated Symptoms of Physical Allergy Urticaria:
Individuals suffering from physical allergy urticaria typically experience:
- Red, itchy welts on the skin
- Swelling in various body parts
- Burning or stinging sensation in affected areas
- Symptoms may appear immediately after exposure to specific triggers and can last from a few minutes to several hours.
Diagnosis of Physical Allergy Urticaria:
Diagnosis usually involves a thorough review of the patient’s medical history along with a physical examination. Healthcare professionals may conduct:
– **Skin tests:** to identify specific triggers
– **Provocation tests:** where the individual is exposed to suspected triggers to observe reactions
