According to statistics from the World Allergy Organization (WAO), the incidence of allergic diseases has increased at least three times in the past 30 years, and the current global prevalence has reached 22%. It is estimated that in 20 years, 50% of the population in industrialized countries will suffer from allergic diseases. Allergies have been listed by the World Health Organization (WHO) as one of the three key diseases for prevention and treatment in the 21st century.
On June 28, 2005, WAO jointly launched a global initiative to fight allergic diseases in conjunction with allergy agencies of various countries. July 8, 2005 was designated as the first “World Allergic Disease Day”.
What is allergy?
To some people, “allergic” is more like a “hypocritical” excuse or subterfuge. For everyone who has experienced allergies, the reactions that allergies bring to them range from ear, nose and throat to skin, from respiratory tract to digestive tract, from mild epidermal abnormalities to severe to cardiogenic shock.
For example, there is no cure for common food allergies in medicine. People with allergies can only choose fasting, that is, avoid foods that cause allergic reactions in the body. For such allergies, their diet is restricted, except that they cannot enjoy food. In addition to the fun, it may often be misunderstood.
The main classification of allergens
According to the survey, there are currently more than 300 allergens that can be detected, and there are even some strange allergens that have never been heard: cold air, ultraviolet rays, grass, watermelon water, grapefruit peel, buckwheat, nicotine, hair, Toilet water…
(1) Contact/inhalation allergens, this kind of allergens are widespread in nature, and it is difficult to avoid contact. Such as pollen particles, dust mite excrement, fungal hyphae and spores, insect venom, animal fur, etc.
(2) Ingested allergens, mainly some food proteins, such as milk, eggs, fish, shrimp, crab, etc. In addition, some food additives and flavoring agents are also important ingestion allergens.
(3) Some drugs, such as penicillin, sulfa, procaine and other drugs, although haptens are not immunogenic, they can bind to certain proteins to become complete antigens after entering the body.
(4) Animal immune serum, various antitoxin serums, such as diphtheria and tetanus antitoxin, are derived from animal serum and are immunogenic.
(5) Others such as subtilisin, certain plant toxins, metals, etc. can also be used as allergens.
Typical allergic disease
IgE sensitivity can lead to the following typical allergic diseases: asthma, rhinitis, allergic eczema, conjunctivitis, food allergy, drug allergy, and anaphylactic shock. The most common ones are allergic rhinitis and allergic asthma caused by allergenic factors such as pollen, dust mites, fungi and pets.
Pollen allergy: The main symptoms of pollen allergy are sneezing, runny nose, watery eyes, and itchy nose, eyes and external ear canal. In severe cases, it can also induce bronchitis, bronchial asthma, and pulmonary heart disease (mostly in summer and autumn). The reason why pollen can cause human allergies is that pollen is rich in protein, some of which are the main allergens causing allergies.
Those who are allergic to pollen should not grow flowers and plants indoors. In addition, during the peak period of external pollen, you should try to avoid going out and close the doors and windows to prevent the entry of allergic pollen to reduce the chance of contact with pollen.
Dust mite allergy: The main symptoms are itching on the face at night. The skin gradually becomes rough and peeling. The pores gradually become thicker and larger, and the pores around the nose have blackheads and continue to increase. Acne and pimples recurring. Small red bumps grow on the chest and back. Peeling, broken hair, split ends, increased dandruff, etc.
Mites are small parasites invisible to the naked eye. They are distributed in carpets, cotton wool pillows, cotton sheets, and house dust. The main preventive measure is to wash sheets and blankets with boiling water every week and dry them in the sun. Pillows and cushions are wrapped in a dense cover. Remove the carpet from the bedroom. Frequent cleaning and dust removal to reduce dust deposits.
Pet allergies: coughing, sneezing, severe breathing difficulties (asthma), small red rashes on the skin, itching where the body has been in contact with pets.
If the allergen is your pet’s fur, dander and its secretions, and excrement, you should remove the pet from your home, or at least keep them out of the bedroom area, bathe your pet frequently, and minimize contact with pets.
Alcohol allergy: Alcohol allergy generally manifests as itching all over the body after drinking, red bumps and red spots all over the body or part of the body, and the duration is mostly one to two days.
You should be careful not to drink alcohol on an empty stomach; do not drink with carbonated beverages such as cola, soda, etc. The ingredients in these beverages can speed up the body’s absorption of alcohol; when drinking, you should eat more green leafy vegetables, and you can eat some fruits after drinking; never take medicine drink.
What do we do in the face of allergies?
Changes in the natural environment and modern lifestyle are the “culprits” that have caused the increase in allergic diseases year by year. The most important treatment for allergic diseases is prevention. To prevent allergic diseases, the most important thing is to cultivate an anti-allergic lifestyle, so as to repair our damaged immune system and reshape our immune balance.
Enhance immunity: Adhere to regularity and proper physical exercise can enhance physical fitness and avoid allergies; in terms of diet, eat more fresh fruits and vegetables and fermented foods, such as fermented cheese and yogurt, especially the probiotics in the latter can help us strengthen Immunity, it is recommended to consume regularly.
Less contact with allergens: After the patient finds the allergen, he should be exposed to the allergen as little as possible. If it is food allergies, you need to avoid such foods and replace suspicious or known allergenic foods and drugs with drugs and foods that can play the same role; if the allergens are like dust mites, pollen, etc., the sooner The better the effect of treatment such as drugs, it can prevent the disease from further aggravating and prevent the risk of multiple allergic diseases. People with allergies should try their best to take anti-allergic measures when going out. Wearing a mask is the easiest measure.
Pay attention to home hygiene: Some people think that regular cleaning in their homes can be described as spotless and there is no allergen. “Someone has done an experiment. The concentration of dust mites that can cause allergies in the bedroom is 100 times that of other parts of the house. The ideal temperature for growth and reproduction is 25°C and the humidity is 75%.” Allergens are likely to be hidden. In the curtains, mats, cushions and plush toys in the house.
