For this, Alopah is here to answer your questions. Alopah is here to answer your questions: Allergy refers to the abnormal reaction of the human body to external harmless and partially harmful substances, also known as allergic reaction, which mainly manifests clinically as rash, sneezing, runny nose, cough, difficulty in breathing, nausea and vomiting.

 

1,Why are there more and more people with allergies?

 

Environmental changes are the main factor leading to the increasing number of allergic people. Studies have reported that the better the hygiene conditions and the less microbial exposure, the more allergic diseases there will be.

 

In recent years, rapid economic development and urbanization have accelerated, and the living environment and lifestyles of urban residents have changed dramatically. Formaldehyde and benzol from indoor decoration, special chemicals from daily chemicals, more dust mites from warm environment due to air conditioning and poor indoor air circulation in summer, lack of outdoor activities for only children, hair and excrement from pets, growth in the number of motor vehicles and outdoor air pollution, changes in dietary structure of residents such as reduced intake of vegetables and fruits, excessive intake of snacks and other convenience foods, childbirth Changes in the way babies and children are fed and so on are the reasons for the increasing number of allergic people.

 

2,Why do allergies affect people’s quality of life?

 

Mild allergies may only cause itching and rash; severe allergies may cause laryngeal edema and shock, which may cause death if not rescued in time. Allergy can involve the skin, respiratory system, digestive system, ear, nose and throat, conjunctiva and other parts of the eye, thus causing a series of diseases, including allergic rhinitis, allergic conjunctivitis, skin allergy, allergic cough, bronchial asthma and so on. Therefore, once allergy symptoms appear, patients should visit the appropriate specialist for symptomatic treatment to relieve allergy symptoms.

 

3, Who is prone to allergies?

 

Allergies can occur in people of all ages, but mainly occur in people with allergies. Allergy is clinically called “atopic”, which refers to a reaction to harmless or partially harmful substances in the environment. Allergic individuals are susceptible to allergic diseases, which are generally genetically related, not related to immune deficiency, and difficult to change. The survey results show that the percentage of infants and children with allergies is 37% when both parents have no history of allergies; the percentage of infants and children with allergies rises to 65% when both parents have a history of allergies. In addition to genetic factors, changes in lifestyle and environmental factors may induce allergic reactions, so allergies are subject to change over time.

4, How to find the hidden allergens?

 

In medicine, the substance that causes an allergic reaction is called an allergen. Once an allergy occurs, finding the allergen is the main part of preventing the occurrence of allergic reactions in the following ways

 

Consultation: Based on the patient’s medical history, symptoms and signs, the doctor can confirm the diagnosis of allergy in some patients, but some routine tests are needed to rule out other diseases. In addition, the doctor may need to perform a skin allergen test to determine which substance the patient is allergic to.

 

Laboratory tests.

 

① Skin prick test: Common screening for allergy to inhaled and ingested allergens. Medications such as anti-allergy medications and glucocorticoids need to be stopped 3 to 5 days prior to the test.

 

② Serum specific IgE test: It is mainly used to assist the doctor to determine the degree or level of allergy to a certain allergen. Generally speaking, the higher the IgE concentration, the higher the allergy level and the more severe the allergy symptoms. The serum specific IgE test is not affected by medication and does not require discontinuation of anti-allergy medication.

 

③ Patch test: Screening for contact allergen allergy. It mainly contains metals, drugs, aromatic substances in cosmetics, chemical materials, etc. For people suspected of contact skin allergy, patch test should be performed about 2 weeks after the acute allergic reaction period, and oral and topical glucocorticoids should be stopped 1 week before the examination, and anti-allergic drugs should be stopped 3 days before the examination.

 

The above allergen test results must be interpreted in the context of clinical practice, and the allergen test report does not mean that the patient is necessarily allergic to a substance.

 

5, What should I do if I have allergies?

 

The first step is to stay away from allergens to avoid further aggravation of clinical symptoms. However, allergens may exist everywhere in life, and it is very difficult to avoid them. If the patient does not know which substance he is allergic to and the allergic symptoms persist and affect the quality of life, he needs to go to the appropriate hospital specialist for symptomatic and causative treatment. If the patient’s allergy symptoms gradually worsen and symptoms such as nausea, vomiting, breathlessness and cold hands and feet appear, he or she must go to the hospital emergency room in time to prevent anaphylaxis. Do regular screening. Allergy patients need to have their allergens retested regularly to confirm that there are no new allergens. In addition, some people do not have allergies immediately after exposure to allergens, such as pollen and dust allergies, which may appear suddenly in a certain season; and a person’s allergy to a substance is not constant for life.

 

6,Can allergic diseases be cured?

 

At present, desensitization treatment can cure some allergic diseases. The main mechanism is to change the abnormal immune response in patients with allergic diseases. Therefore, patients who have been suffering from allergies for many years can go to the allergic reactions department of local hospitals to consult whether desensitization is possible.

 

7,How can people who are prone to allergies prevent allergies?

 

Learn more about the science of allergy and correctly understand allergic body and allergic diseases.

 

Find allergens and try to avoid contact with known allergens in your life.

 

Strictly follow the treatment plan of your specialist to avoid recurrent allergy attacks.

 

Keep a life diary and observe and record allergy-related factors from diet, environment, and other aspects.

 

Promote breastfeeding as it has a preventive effect on allergic diseases in infants.

 

Hypoallergenic hydrolyzed formula has a preventive effect on food allergy.

 

Desensitization therapy is available for those who have the condition.

 

8,What are the common allergens that allergic individuals should avoid contact with?

 

Inhalant allergens: including various dust mites (house dust mite and dust mite are the most common), various molds (Streptomyces, Aspergillus niger, Bacillus, etc.), insect excrement and body fragments (such as cockroaches), various grass pollens (ragweed, artemisia, humulus, large nettle, sunflower, etc.), tree pollens (cypress, ash, elm, mulberry, willow, sycamore, etc.), animal hair (cat hair, dog hair, wool, etc.).

 

Ingested allergens: various foods, such as egg whites, milk, shrimp, crab, lamb, beef, wheat flour, cashew nuts, peanuts, wheat fruit, etc.

 

Contact allergens: including a variety of cosmetics, chemical materials (formaldehyde, etc.).

 

Injected allergens: including drugs for injection (penicillin antibiotics, anesthetic drugs, certain immunoglobulins, vaccines, etc.), and toxin proteins injected into the body after bee bites.
