We know that once there is a wheal like rash on the skin, we can determine that we have urticaria. The diagnosis of urticaria is very simple, but it is often not easy to diagnose the cause. What causes urticaria? How should it be treated? Now let's have a look!
What reason is urticaria caused
1. Drug induced: most drugs are caused by allergy. Common drugs include penicillin, furazolidone, serum products, vaccines, etc. Its onset has a certain incubation period. Aspirin, morphine, atropine, vitamin B1, polymyxin and other drugs are histamine releasing agents, which can directly stimulate mast cells to release histamine and produce urticaria.
2. Cold, heat, sunlight, friction, compression, mechanical stimulation, etc.
3. Such as gastrointestinal diseases, tumors, connective tissue diseases, endocrine disorders and metabolic disorders can also become the cause of urticaria.
4. Food causes: common pathogenic foods include fish, crab, shrimp, eggs and other foods rich in animal protein, as well as some commonly used seasonings, edible pigments, preservatives and so on. There are also nuts, fruits and vegetables that can cause skin allergies.
5. Inhale animal dander, pollen, fungal spores, dust, feathers, etc.
6. Such as bacterial infection, fungal infection, virus infection, parasitic infection, etc.
7. Mosquitoes cause the bites of insects such as mosquitoes, ants, fleas and bees. Some people may also have allergic reactions to common butterflies, moths and even ladybugs.
8. Mental tension, mood swings and depression can also be the inducing factors of urticaria.
9. Familial heredity.
Harm of urticaria
1. Endanger the patient's life
If urticaria occurs in the throat and bronchus of the respiratory tract, it will lead to recurrent laryngeal edema, throat blockage, shortness of breath, chest tightness and dyspnea. In severe cases, it will lead to asphyxia and death. Severe cases will be accompanied by panic, irritability, nausea, vomiting, even decreased blood pressure and other anaphylactic shock symptoms, endangering life safety.
2. Induce the occurrence of other diseases
If urticaria is accompanied by gastrointestinal symptoms, it will cause nausea, vomiting, diarrhea, abdominal pain, gastrointestinal dysfunction and other symptoms, accompanied by ulcerative colitis. The main cause of urticaria is immune dysfunction, which can induce nephritis, autoimmune hyperthyroidism, SLE, and even low immune surveillance function, leading to malignant tumors. Reproductive women can also lead to immune infertility and abortion.
3. Affect the quality of life of patients
If urticaria is not cured in time, it can be extended for months or even years. The symptoms of itching in the morning or before going to bed will gradually aggravate, affecting people's normal life and psychological state. Therefore, urticaria must be treated thoroughly. If it is allowed to develop, it may lead to very serious consequences.
How is urticaria treated
1. Pay attention to allergic reactions caused by drug factors
In clinic, some drugs can cause urticaria. The most common antibiotics are penicillin and aspirin. When going to the hospital for medical treatment, doctors often prescribe these two drugs. Once there is no skin test, some people are easy to cause allergies.
2. If you have other diseases, you'd better cure them first
Urticaria is not only an independent disease, but also a skin manifestation of other diseases. There are also many other common diseases that cause hives, such as infectious diseases, tonsillitis, otitis media and so on. In addition, diabetes, menstrual disorders in the presence of tumors have the opportunity to cause urticaria.
3. Pay attention to diet
The incidence of urticaria is related to food, some of which may be the inducement. Such as fish, shrimp and other seafood, as well as foods and beverages containing artificial colors, preservatives and yeasts, may induce urticaria. In addition, spicy food is also best not to eat. Because it will reduce the digestive capacity of the intestines and stomach in the body, resulting in the food staying in the body for a long time, which is easy to produce polypeptide proteins, which greatly increases the probability of skin allergy.
4. Maintain good living habits
Especially those who have had allergies before, pay attention to keeping the room clean and hygienic, and try not to keep pets at home. In addition, avoid raising some stimulating flowers with strong smell. It is easy to be allergic to inhaled pollen. Life must be self-discipline. It's best not to form bad habits. Don't participate in activities such as drinking and stimulating intense mood, because these will aggravate the expansion of skin blood vessels and aggravate the condition of urticaria. In addition, wearing clothes such as chemical fiber and wool is also easy to stimulate the skin for people with sensitive skin.
5. Keep positive and healthy
Generally, the attack and aggravation of urticaria are related to people's mood and psychology. There was a similar article about "someone is angry, has a bad temper, and suffers from urticaria leading to shock". This situation is not joking. Therefore, maintaining a happy and peaceful state of mind is extremely beneficial to urticaria.
