Why are more and more people allergic to pollen

1024, 1186, 1720, 1466, 2386, 1362.

Since April, the pollen concentration in Beijing has remained high.

The high pollen concentration and the high incidence of willow catkins have caused many people to lose out in the fight against various allergic symptoms.

More and more people are allergic

Often eat high-calorie, low-fiber fast food, living environment is too clean, when allergens accumulate to a certain degree, people with allergies will gradually get sick

It seems that only a few people have been recruited for allergies, but in recent years, people generally feel that more and more people around them are suffering from allergies.

"Most people have inherent allergies, but why don't they get sick?" Guan Kai, deputy chief physician of the Allergy Department of Peking Union Medical College Hospital, explained that allergies mainly depend on several factors.

Guan Kai believes that in the past two to three decades, the living standards of ordinary people have improved significantly.

　　Of course, there are also environmental factors.

Who is the culprit of allergies

　　Cypress, birch, sycamore, ash, and Ailanthus altissima rely on wind to spread pollen, and they are important regional allergens.

　　According to Guan Kai, with the arrival of spring, many trees need to be pollinated by the wind to spread large amounts of pollen (male reproductive cells).

　　Therefore, in the spring, many patients will continue to experience symptoms of sneezing, runny nose, coughing or asthma, allergic rashes on the face, eyelid edema, and even plant-derived food allergies.

　　In addition, in the current season, the willow catkins that can be seen everywhere in the north are also considered to be allergens, which may not actually be the case.

How to cure allergies

　　According to different pollen dissemination time, carry out corresponding preventive treatment; during the period of rapid development of allergies, allergen-specific immunotherapy should be carried out

　　How to prevent or treat pollen allergy? Guan Kai suggested that patients with allergic symptoms in spring should go to hospitals with allergy departments, or allergy departments in respiratory and ENT departments, the main purpose is to identify allergens.

　　Sun Jinlu also suggested that, given that there are so many birch and cypress trees in the north, northern patients with pollen allergies can go to the south for business trips or live in another city in the corresponding season, and their symptoms may be significantly reduced or disappeared.

　　If the above methods are not effective, you should use corresponding anti-allergic drugs to control your symptoms under the guidance of your doctor.

　　“If the doctor evaluates that the patient’s allergies are in a period of rapid development, asthma may occur, or even be combined with certain plant-derived food allergies.
