What Are the Signs of an Allergic Reaction to Beer?

Allergy history is a history of allergies to certain allergens and can provide a reference for doctors' diagnosis. Thousands of substances can cause allergies. They exist in the air, food, beverages, drugs, and even daily necessities. These substances are called "allergens".

History of allergies to certain allergens

There are thousands of allergens that can cause allergies. They are in the air, food, beverages, drugs, and even daily necessities. These substances are called "allergens". In simple terms, allergens can be divided into the following categories based on how they enter the body:

Dietary allergens

Dietary allergens can be some common foods and beverages, such as seafood, nuts, strawberries, spices, milk, beer or alcoholic beverages can cause the most common skin allergies ----- -Hives. Many other allergens are hidden in other foods. If you are sensitive to a food, you may have an allergic reaction to that food. For example, hundreds of foods contain milk, wheat, eggs, spices or MSG.

Contact allergens

Allergies can be caused by contact with toxic ivy and toxic oak and metals (nickel) and dyes. There are also general daily necessities such as perfume, nail polish, cosmetics and rubber. The allergic area will show rash and itching similar to urticaria, but its scope is limited to allergens in contact with skin.

Airborne allergens

Airborne allergens cause a variety of allergies due to their ability to spread remotely. Among them, pollen, mold and algae can cause the most common type of nasal allergy, hay fever. The hay fever season starts from spring to autumn. Other allergens spread in the air

Overview

Generally speaking, people who are prone to allergic reactions and allergic diseases but cannot find the cause are called "allergic constitution". People with an "allergic constitution" can experience various allergic reactions and allergic diseases, such as eczema, urticaria, and allergic asthma, and some are particularly sensitive to certain drugs, which can cause medicinal properties. Dermatitis, even exfoliative dermatitis. However, occasionally high responsiveness to a known factor cannot be called "allergic constitution".

Causes of Allergies

The causes of "allergic constitution" are complex and diverse. It may be because children's skin is relatively delicate, which can be caused by wind or sun exposure. Therefore, pay attention to avoid the above factors. In addition, pay attention to whether children eat breast milk. Eat breast milk. Mothers do nt pay attention to their diet. Eating fish and shrimp can cause allergies in children through breast milk. This requires adults to pay attention to diet. Avoid foods that are allergic to foods such as fish, shrimp, mushrooms, strawberries, flowers, etc.

From an immunological point of view, people with "allergic constitution" often have the following characteristics:

Immunoglobulin E (IgE) is an antibody that mediates allergic reactions. The content of IgE in the serum of normal people is very small, and the serum IgE of some people with "allergic constitution" is 1.000 times to 10.000 times higher than normal people.

Normal human helper T cells 1 (Th1) and helper T cells 2 (Th2) have a certain proportion of the two types of cells, the two coordinate, so that the body's immune balance. Some people with "allergies" often have a predominance of Th2 cells. Th2 cells can secrete a substance called interleukin-4 (IL-4), which can induce IgE synthesis and increase serum IgE levels.

The normal human gastrointestinal tract has a variety of digestive enzymes, so that the proteinaceous food entering the gastrointestinal tract is completely decomposed and then absorbed into the blood, while some "allergic constitutions" lack digestive enzymes, and the protein is absorbed into the blood without sufficient decomposition To make heterologous proteins enter the body and cause gastrointestinal allergic reactions. Such patients often lack protective antibodies distributed on the surface of the intestinal mucosa, secretory immunoglobulin A (sIgA). The lack of such antibodies can cause intestinal bacteria to cause inflammation on the surface of the mucosa, which accelerates the intestinal mucosa against xenogeneic Protein absorption and induce gastrointestinal allergic reactions.

The normal human body contains a certain amount of histamine, which has a destructive effect on the histamine released by certain cells in the allergic reaction (which can cause smooth muscle contraction, capillary dilatation, increased permeability, etc.). Therefore, even if a normal person has an allergic reaction to certain substances, the symptoms are not obvious, but some people with "allergic constitutions" lack histamine enzymes, and can not destroy the histamine that causes the allergic reactions, and show obvious allergic symptoms.

The root cause of these immunological abnormalities is often closely related to heredity.

The causes of skin allergies include internal factors and external factors:

The intrinsic factor is that it has an allergic constitution, which plays a leading role in the onset of skin allergies. Early and thorough desensitization is the key to treating skin allergies and preventing recurrence.

There are many external factors. Including diet, inhalation, climate, exposure to allergens, etc. Among them, seafood, protein, spicy food, wine, inhaled pollen, dust mites, cold weather, exposure to chemicals, soap, detergent, etc. are the most common causes of skin allergies. Due to such complex reasons, skin allergies repeatedly occur due to the intertwining of numerous onset causes and inducing factors.

Skin allergy is the culprit of acne: According to outpatient experience in European and American countries, skin allergy is an important cause of acne among patients seeking treatment for acne. In particular, some acne are too many and itchy, even after treatment, it is sometimes good and bad. Generally speaking about the cause of acne, it is usually caused by diet, hormonal inconsistency, stress or heredity. However, it is found from clinical cases that some unexplained and difficult to cure acne are due to not treating the skin at the same time. Recurrence due to allergies. After taking the skin allergy treatment kit, my skin problems will soon improve.

Skin cell physiology research points out that sensitive skin is because skin cells are damaged, which weakens the skin's immunity. If these damaged cells are not repaired in time, they will continue to split out of poor immunity and incomplete secretion of sebum membranes. As a result, various sensitive skin problems and many sequelae can occur, such as long-term skin allergies, pigmentation, swelling, enlarged pores, acne, pigmentation, and aging wrinkles caused by skin injuries due to allergies.

Allergies are a big problem that plagues the beauty and medical industries, especially cosmetics allergies are the problems encountered by many women and special professionals, including: lipstick caused by lips swelling, pain, scalp erythema caused by hair dye, blisters, sunscreen , Itching, pain and pigmentation caused by freckle remover. People with allergies have sensitive skin, and even seemingly simple cosmetics can cause adverse reactions. Common are lipsticks and hair dyes. After use, allergic problems such as skin redness, swelling, heat, itching, pain, and blisters appear. Not only can't find beauty, but embarrassment often happens.

Nomenclature of the disease:

Asthma (according to GINA guidelines): Asthma is a chronic inflammatory disease of the respiratory tract in which a variety of cells, especially mast cells, eosinophils and T lymphocytes, all play a role in the inflammation process. In susceptible individuals, this inflammation The reaction results in recurrent episodes of wheezing, dyspnea, chest tightness, and cough, which usually occur at night and early in the morning. This inflammatory response can also cause the respiratory mucosa to become more responsive to various irritants.

Allergic asthma: Allergic asthma refers to asthma mediated by the immune mechanism. "IgE-mediated asthma" is recommended when there is evidence of an IgE-mediated allergy mechanism. IgE antibodies can stimulate rapid onset and Delayed asthma reactions. However, in other allergic reactions, T cell-related reactions may be important factors in late and delayed reactions. Asthma can be divided into intermittent and persistent two categories based on the duration of symptoms (just As in "

Allergens are also called allergens or allergens. Among them, allergen is a popular term, and allergen or allergen is a medical term, which refers to an antigen that can cause human allergy. Their common feature is: after a certain period of exposure to allergens, the body is sensitized. The sensitization period can be long or short. There are no clinical symptoms during this period. An allergic reaction can only occur after re-exposure to the allergen. Therefore, often the first contact with the substance will not be allergic, after repeated exposure, allergic symptoms may occur. Symptoms generally worsen after repeated exposure.

In the process of allergies, allergic media play a direct role. Allergens are a necessary condition for allergic conditions, and the presence of a large number of free radicals is the source of allergies. Free radical oxidation damages the cell membranes of mast cells and basophils, causing them to be damaged, degenerate, and the body's immune capacity is low, creating conditions for the occurrence of allergic immune reactions of antigens and antibodies, leading to cell rupture and release of allergic media, making allergies Illness occurs.

There are four main types of commonly used anti-allergic drugs:

(1) Antihistamine

This is the most commonly used anti-allergic drug and is most suitable for type 1 allergic reactions. Commonly used are diphenhydramine, isopropyl, chlorpheniramine, cyproheptadine, zismin, tefalatin, etc. These drugs are H1 receptor blockers. Because they have a similar chemical structure to histamine, they can compete with histamine receptors and have a better effect on skin and mucous membrane allergic reactions. Itchy skin and edema have good effects; it is also effective for measles-seeking sera, but it is not effective for people with joint pain and high fever;

The World Health Organization WHO clearly states in its guidance document on immune desensitization that "desensitization is the only fundamental treatment that can completely treat allergic diseases."

The international authoritative organization for allergy research has also proposed that "the use of high-quality standardized desensitization agents should also use the best allergy treatment plan, including elimination of allergens, immune repair of patients, appropriate symptomatic medication for allergic inflammation, standardized desensitization Preparation of immunotherapy, referred to as "six in one six combination therapy" program.
