What is Urticaria?
What is Urticaria? Urticaria are skin reactions characterized by red or white wax that itch. These bilur can appear in one part of the body or spread to other body parts. The size and shape of the wound can vary, from a few millimeters to the size of a hand. One common cause of heresy is allergy
In addition to itching, rash in urticaria cases can also feel sore or stinging. This rash can appear in all parts of the body, including face, lips, tongue, throat, and ears. Symptoms of heresy may last for several hours or days.
There are various types of urticaria. Urticaria that occurs for less than six weeks is referred to as acute urticaria. In addition, there are also cases of urticaria that last more than six weeks, or are recurrent for several months or even years. This rare condition is referred to as chronic urticaria. Chronic urticaria may be a symptom of another disease, such as thyroid disease or lupus.
In addition to acute and chronic urticaria, there is also the so-called physical urticaria and dermatography. Physical urticaria is caused by direct physical stimulation of the skin, such as hot or cold temperature stimulation, sunlight, pressure, vibration, or sweat. While dermatographism is a skin condition that is formed after scratching the skin hard.
Urticaria itself is a common condition experienced by all people at all ages. However, heresy is more common in children and women at the age of 30-60 years. In addition, people who have a history of allergy are also more at risk to experience it.
Causes of Urticaria
The appearance of wounds on the skin is triggered by high levels of histamine and other chemical compounds released by the layer beneath the skin, causing tissue swelling. Histamine can sometimes cause leaking of plasma fluid from the blood vessels, resulting in fluid accumulation or angioedema. Excess fluid is also what causes skin swelling and itching. The release of histamine which causes the heresy can be triggered by various things, including:
The following are some of the things that could lead to heresy:
- Exposure to hot or cold air.
- Contact with triggers or allergens (eg insect bites).
- Certain drugs (eg antibiotics and nonsteroidal anti-inflammatory drugs)
