Hidden killer: urticaria

Urticaria, also known as "rubella block", medical terminology called "wheal", is often called "wind knot", it is a kind of edema reaction due to the expansion and penetration of small blood vessels in the skin and mucous membranes. It can present as a wheal, as angioedema, or both. Usually the symptoms are mainly itching unbearable.
Urticaria is a high spring incidence and is also a common and frequent disease in dermatology. Whether in the outpatient clinic, emergency department, or inpatient department, there will be urticaria patients. This is because about 1/4 of the people in our population will get urticaria at least once in their lifetime, and 1/4 of these 1/4 may become chronic urticaria patients.
Generally speaking, the boundary between acute and chronic urticaria is mainly divided by the duration of the disease, less than six weeks is acute urticaria, and more than six weeks is chronic urticaria. Acute urticaria can develop into severe allergic reactions, also known as allergic reaction syndrome.
Looking at this picture, is it all goosebumps. This is just the appearance, urticaria is not only a symptom on the skin, but when severe, it can affect the respiratory tract, digestive tract, cardiovascular system, and even the nervous system.
Urticaria can affect the respiratory system, causing small airways, bronchospasm in the human body, there will be symptoms such as holding breath, chest tightness, breathlessness, difficulty breathing, and sometimes suffocation, which can lead to death.
There is also the digestive system, which can show nausea, vomiting, diarrhea, abdominal pain and so on. When urticaria affects the nervous system, irritability, confusion, and even loss of consciousness, syncope, etc., the more serious result is that if the rescue is not timely, it can endanger life.
Perhaps, you think of hives as a "loner". Non also. There are many diseases that may have concomitant urticaria: autoimmune diseases such as thyroid, lupus erythematosus, etc.; acute or chronic infections, such as upper respiratory tract infections, urinary tract infections, Helicobacter pylori infections, gastrointestinal diseases, cholecystitis, gallstones, etc.; tumors, such as lymphoma, myeloma, etc.; neuropsychiatric diseases, such as depression. There is no sense of urticaria everywhere.
Someone has a pair of ear-catching ears, which is a figurative metaphor. And you who have been in a state of mental stress for a long time and have an imbalance in life and work, but you have a sick body, not to mention urticaria, other diseases can not be stopped.
Professor Liu Lingling, chief physician of the Department of Dermatology of Peking University First Hospital, reminds professionals to identify urticaria in their daily work, understand the characteristics of urticaria, and prevent contact allergens.
There are three main characteristics of urticaria: one is that the surface of the skin generally appears rash, wheal, angioedema; the second is that it subsides from time to time, fades without leaving a trace, comes and goes quickly; the third is itching, or there is some burning sensation.
For special urticaria, it is convenient to conduct a self-test at home through an ice test or a skin scratch test.
Professor Liu particularly emphasized the need for standardized treatment. The so-called standardized treatment, mainly from the doctor's point of view, should be based on the condition and individual differences, weigh the efficacy of the drug, choose the correct treatment plan and means; from the patient's point of view, to follow the doctor's instructions, on time and quantitative treatment, responsible for their own health.

This is mainly those who do not have an explicit cause, or external factors such as mental stress, or patients who cannot be completely eradicated due to other diseases, such as thyroid disease.
