Tips for World Allergic Disease Day 2022 Four parts of the body are the most susceptible to allergies.
Allergy, a seemingly insignificant problem, has long been listed as the sixth chronic disease in the world. According to the statistics of the World Allergy Organization, 30% to 40% of ordinary people in the world suffer from allergic problems. Global scope:
About 250 million people have food allergies, 300 million people have asthma, 400 million people have rhinitis, and one tenth of the total population has drug allergic reactions.
Many people mistakenly think that allergies are skin reactions. In fact, it is an immune system disease, including eczema, urticaria, allergic rhinitis, asthma, allergic conjunctivitis, food allergy, drug allergy and so on.
In medicine, this allergic condition caused by the attack of the immune system on harmless substances is called "allergic reaction"
Allergic disease is a common systemic disease, which can occur at all ages. The following parts of the body are most susceptible to allergies:
skin
Skin is the largest "defensive" organ of human body, which plays the role of protection, absorption, excretion, sensation and temperature regulation, and is also an important immune organ of human body.
Manifestations: urticaria, atopic dermatitis (atopic eczema), drug dermatitis (drug eruption), solar dermatitis, contact dermatitis, vascular edema, etc.
Their common feature is unbearable pruritic rash, which may even lead to anaphylactic shock and life-threatening.
In addition, other serious skin diseases, such as cutaneous vasculitis (including cutaneous tuberculosis) such as allergic purpura, immune bullous disease (including pemphigoid and pemphigus), connective tissue disease (such as lupus erythematosus), etc. also belong to skin allergic diseases.
respiratory tract
The respiratory tract is divided into upper respiratory tract and lower respiratory tract, which communicate and influence each other. Among the representatives of respiratory allergic diseases, allergic rhinitis and asthma are the most common.
Manifestations: nasal congestion, sneezing, clear water and runny nose, and asthma is characterized by cough and asthma.
Half a century ago, some scholars pointed out that allergic rhinitis was closely related to asthma. Epidemiological investigation shows that if allergic rhinitis is not treated properly, 25%~38% patients will have asthma symptoms and eventually develop into emphysema or even pulmonary heart disease.
In addition, lung diseases related to sinusitis, allergic pharyngolaryngitis and fungal allergy also belong to respiratory allergic diseases.
eye
Allergic conjunctivitis is the most common ocular allergic disease.
Manifestation: itchy eyes. Other symptoms include tears, burning sensation, photophobia and increased secretion. Some severe allergic conjunctivitis sometimes leads to decreased vision and seriously affects the quality of life.
gastrointestinal tract
Allergic gastroenteritis, also known as digestive system allergy or food allergy, is an immune response caused by a certain food or food additive, which leads to allergic reactions in the digestive system or the whole body.
The prevalence of food allergic reaction in children is about 6%~8%, and milk is the most common allergic food, accounting for about 3%~7.5%. Patients with food allergy are often accompanied by bronchial asthma, and the incidence rate is about 6.8% ~17%. The incidence of asthma in children allergic to milk is as high as 26%.
Severe allergies can cause anaphylactic shock. After exposure to allergens, patients can rapidly develop from mild skin symptoms to angioedema, blood pressure drop, arrhythmia, loss of consciousness, shock and even death within a few minutes.
Among them, drugs and food are the chief culprits of fatal anaphylactic shock.
Allergen detection
At present, skin test and serum specific IgE detection are mainly used for allergen screening in clinic.
Skin test: including intradermal test and prick test. Identify allergens by whether there are allergic reactions such as redness and wheal in the skin test site.
The former makes possible allergens into preparations and injects them into patients' skin; The latter is to drop the allergen preparation on the skin of the patient's forearm and puncture it with a special needle.
Serum-specific IgE detection: it is necessary to draw blood, and the diagnosis can be made by allergen-specific IgE antibody in blood.
If the allergen test report shows that an allergen is positive and an allergic reaction will occur after contact with this substance in life, you can determine that you are allergic to it.
How to save an allergic person?
Compared with ordinary people, allergic people should not only learn to avoid allergens, but also do the following life details.
1, greasy diet is the most taboo.
The daily diet is best to be light and balanced, and the thickness of meat and vegetables is appropriate. People with allergies should try to eat less greasy, spicy and irritating foods, less fishy, strong tea and coffee, and less sweets.
It is suggested that eating more foods rich in vitamins can enhance the body's immunity. Cabbage and citrus foods help to improve allergies.
Step 2 adjust your living habits
Regular daily life, don't stay up late. Wash your face and brush your teeth with warm water and change clothes frequently. Pillows, sheets, bedding, etc. It should be cleaned and dried frequently. Don't stay in places with high pollen concentration or where paint is being painted.
3. Exercise regularly
Proper exercise can strengthen the body's resistance. Increasing outdoor exercise helps to relax. At the same time, patients can cooperate with medicated diet to enhance immunity, which has a significant effect on improving allergic constitution.
Step 4 stay away from allergens
In spring, patients should reduce outdoor activities, avoid contact with pollen and prevent allergies. If necessary, carry out allergen examination as a reference.
Allergy to pollen, mold, pets and mites: desensitization treatment can be carried out. Generally speaking, it can take effect in 3~6 months, and the drug should continue to be used after the symptoms disappear.
It is recommended to treat for 2 years, which can ensure the curative effect lasting for many years or even for life.
Food allergy: Although there is no cure at present, finding out the allergic food in time can avoid the disaster from the mouth.
Skin allergy: Allergic people usually have sensitive skin. Choose skin care products carefully, and don't use products containing spices, alcohol and fruit acid. This product is very irritating to the skin and easily causes allergies.
