The last decades have led to tangible progress in medicine and science, but the health of mankind as a whole has not changed. For the elderly there are more and more new diseases. It seems that scientists are struggling with the treatment of some invincible misfortune, and at this time nature is throwing up new tasks, as if offended by an inattention to it.
The leader in the number of new forms is rightly considered an allergy. The inexorable statistics testify, that such disease is present at 25% of inhabitants of a planet. The basis of most allergic reactions are immune processes, which are activated when an unwanted microorganism or substance enters the body. Thus, there are a lot of factors for the appearance of allergies. Traditional agents of the disease are viruses, medicines, bacteria, pollen, wool and food.
However, in the 20th century such elements as plastic, synthetic cosmetics, artificial building materials and even radio waves were added to them. Today, more and more new allergens are being detected, this has become so commonplace that nobody surprises. However, sometimes even doctors are surprised by the results and manifestations, because allergies are hypersensitivity to certain substances, which manifests itself in the form of unusual reactions to them.
Allergy is manifested in different ways. It can be prolonged and exhausting sneezing attacks, with discharge from the nose, there may be lacrimation and itching in the eyelids and nasopharynx, and also on the skin. A rapidly developing allergic reaction can even lead to anaphylactic shock. Considering the fact that the disease can occur with anyone and at any time, we will tell you about several of the most well-known allergic reactions to quite ordinary subjects.
Allergy to the Sun.
Spring comes, and summer comes after it. People, naturally, tend to keep warm and sunbathe. Just to do to those who have sun-light is not a beautiful tan, but redness, irritation, and even blisters? Allergy to the Sun is a very common phenomenon, it is found in an increasing number of people. The cause of this reaction (sun dermatitis or photodermatitis) is the effect of sunlight on the exposed human skin. By themselves, they are not allergens, and irritation can occur either because of external factors, or because of internal factors. External factors include allergenic substances, which gradually accumulate on the surface of the skin. It can be pollen of flowering plants, cosmetics or medical products, essential oils. They are under the influence of the sun and cause an allergic reaction in the open areas of the skin. Internal causes are usually diseases and disorders of the immune system, as well as the consequences of taking certain medicines. This all leads to an increase in the sensitivity of the skin to the Sun, which increases its vulnerability. The combination of ultraviolet and drugs can become extremely dangerous, causing a strong allergy. Symptoms of it are similar to the usual skin reaction – staying on the sun leads to redness of the skin, burning and itching. Those areas of skin that have been exposed acquire a rash similar to urticaria. Allergy to the sun can manifest itself in the form of swelling of the mucous membranes and skin in general. It is interesting that an allergy to the sun can also appear in the solarium. There in the cold season there are those who would like to give the skin a summer bronze tan. However, an artificial tan as an unpleasant companion can have an allergy to the solarium. Symptoms of the disease are similar to photodermatitis, so the question of the benefit or harm of the solarium remains open.
Allergy to water.
Everyone knows that water is life. It is all the more surprising to hear that there are those who have an allergy to water. Usually, the disease occurs with a sharp drop in water temperature and is usually seen in people in Africa, India and other countries with a hot climate.These people have limited access to liquids, as a result of which their skin is weaned from constant moisturizing. When it gets cold or hot water, then the body begins to appear red spots, rashes and even micro-burns. Water brings the weakened from her body peculiar problems. Similar, but weaker manifestations can occur with a long bath in warm water. The skin then forms small spots that begin to itch and look like irritations. Although this kind of allergy is quite rare, there were no fatal outcomes, although in India cases of instant burns from getting to the skin of water were recorded. Until now, scientists have unclear the true causes of such a strange effect of moisture on the human body. A case of young Australian Ashley Morris, who received such an allergy after a childhood illness with angina, is known. Doctors prescribed her medicine, which included a lot of penicillin. Soon the girl found out that after taking a bath on the body appears a bright red rash. Dermatologists determined that the drugs changed the amount of histamine in the blood, which led to a disruption in the regulation of functions. Now, any touch to the water causes the girl to have an itchy rash and peeling. She can not even walk down the street, because the sweat immediately leads to a skin reaction. But in this situation Ashley finds its advantages – she will never have to wash and wash dishes.
Allergy to alcohol.
The very word “allergy” conjures up pictures with dust, wool, citrus and other things. However, there are people in nature who have a reaction to alcohol. It manifests itself in the redness of the hands, face and torso. The skin gets rashes and itching, a runny nose is attacked, and even choking can occur in especially severe cases. In the case of possessing such reactions, it is better not to limit the reception of such alcohol, but to abandon it altogether. And it’s not so hard as it seems. The most common is intolerance to red wine, it occurs in 10-15% of people. However, the allergy is most often caused not by the alcohol itself, but by the polyphenolic compounds that are in it (most often in the same wine). So it turns out that there is almost no allergy to vodka. Moreover, alcohol, as it turned out, reduces the allergenic properties of other foods. French doctors even recommend to wash strawberries with wine to those people who are allergic to it. In this case, it is recommended to choose natural white or red varieties of the drink, which should be slightly put before use. It is argued that this will help to avoid undesirable consequences.
Allergy to cow’s milk.
Milk contains about 20 different proteins, including 4 main allergens. The most significant of these are alpha-lactalbumin, beta-lactoglobulin, and casein. The latter consists of 80% milk proteins, there are 5 sub-fractions, of which alpha-casein and alpha-es-casein are noteworthy. Since casein is not a part of species-specific proteins, an allergy to it can be accompanied by an increase in sensitivity to cheeses and other dairy products of animals. The fact is that these substances also contain casein. 10% of all milk proteins are beta-lactoglobulins, which are part of the milk of all animals, and alpha-lactalbumin accounts for 5% of milk proteins. This allergen is also species-specific, an allergy to it can be accompanied by a cross-reaction to the proteins of cow meat. Another significant protein of milk is lipoprotein, it is much less active than previously listed, but it is responsible for the occurrence of reactions to butter. That is why it is important to remember that in condensed and dried milk contains all the same milk antigens, they are also present in the products that are prepared with its use. In other words, an allergy to dairy products can manifest itself with consumption of white bread, ice cream, buns, mayonnaise, chocolate and so on.It happens that patients have an isolated allergy to cheeses, but there are no reactions to milk. Then we can talk about increased sensitivity not to milk proteins, but to molds used in the production of cheese. In general, the allergy to milk is most common in children, usually it manifests itself and begins with the introduction of complementary foods. This is especially clear when there is an allergy to beta-lactoglobulins. Usually, significant allergic manifestations are manifested in diarrhea and vomiting, but excluding cow’s milk from the diet can quickly lead to a significant improvement in the child’s condition. By the second year of life, moreover, the baby may experience a spontaneous recovery, associated with the maturation of the digestive organs and their defense mechanisms. In adults, however, true allergic reactions to milk are extremely rare, and poor milk tolerance is associated with a lack of enzymes that break down proteins. Activity of such substances decreases after puberty of the person. It is interesting that half of people with this type of allergy develop an immediate reaction, which is caused by immunoglobulin E and manifests itself in violation of various functions of the body. This is manifested in digestive disorders (diarrhea, vomiting, nausea), allergic skin reactions, allergic rhinitis and bronchial asthma. In the other half of the patients, a delayed-type reaction, its symptoms are associated exclusively with the gastrointestinal tract.
Allergy to fish.
This kind of disease occurs quite often, especially in those countries and areas where food is traditional food. About a third of patients have selective allergies to one of the fish species, while others experience undesirable reactions to many species at once. At the same time, sea fish is more allergic than fresh fish, and thermal treatment can not destroy allergens at all. In those areas where fish are brewed, its antigens are abundantly contained in the air, which leads to the formation of fish distillate. This, in turn, contributes to ingestion of human allergens by inhalation. Also, a strong allergen is caviar, but the fish oil of reactions usually does not cause, it affects only people with high sensitivity to this kind of allergens. It is worth mentioning that the most strongly the human body can react to crabs, crabs, lobsters and shrimps. If there is an allergy to crustaceans, then it is worthwhile to fear and inhalation allergens from daphnia, which are used as food for the inhabitants of the aquarium.
Allergy to fruits and vegetables.
Reactions of this type can be caused by many vegetables and fruits – representatives of plant families. The emergence of pseudoallergic and allergic reactions most often result in tomatoes, all citrus fruits, bananas, carrots, peaches, garlic and onions. It is curious that the prevalence of allergies to such products may be due to climatic and geographical features. For example, for people over 10 years in the US, an allergy to peaches is more pronounced than anywhere else. Recently, there has been a reaction to the representatives of the laurel family. The most famous of the fruits of this group is avocado, do not forget and numerous spices and spices: leaves laurel, cassia, cinnamon. Interestingly, there is a structural similarity between avocado, banana and latex antigens. The juice of rubber plants, usually Brazilian hevea, is used to make a group of products, from rubber products to chewing gum. Although latex allergy has its own characteristics, it should be noted that antigenic crosshairs can lead to a reaction to the rubber when using products of the laurel family, especially avocados. That is, having tried this fruit, you can get a rash from wearing unremarkable hitherto rubber gloves. Of the fruits in the end, the most allergenic are pears, apples, stone fruits (peach, cherry, apricot, etc.), as well as walnuts, almonds, peanuts and chestnut.From vegetables it is necessary to allocate tomatoes, spinach, a celery and a parsley. Sometimes even simple storage or slicing of kiwi fruit can cause a generalized reaction in persons with increased sensitivity. Almost always the allergy to vegetables and fruits is inextricably linked with the allergy to pollen of plants. It is noted that half of those who suffer from allergies to apple pollen suffer from allergies to the apples themselves. However, the allergens of vegetables and fruits do not tolerate the temperature, so they are destroyed by cooking.
Allergy to people.
You can often hear one person say to the other that he has an allergy, thus expressing his irritation. However, it turned out that such a statement has a scientific basis, the symptoms of such irritation require intervention not of psychologists, but of doctors. In particular, it has been established that the smell of a person, to be exact, its sweat, causes an allergy. And this statement applies most often to male smells. For the first time such reactions were recorded in the middle of the twentieth century. But then it was considered something unusual, because the ecological situation was quite stable and there was nothing to say that there were any prerequisites for the formation of adverse reactions of the body to the smell of sweat. But recently, cases of women’s reactions to male sweat have increased. Scientists believe that this is due to a general increase in the number of allergic diseases and increased qualification of allergic doctors. Such allergies are accompanied by asthma attacks, fever, diarrhea, vomiting, swelling, skin rashes and itching and even loss of consciousness and circulatory disorders in the brain. Like any other form of allergy, this one can grow with time and move into more severe forms, the treatment of which will be already complicated.
Allergy to medicines.
A person can also react to medications and medications, which is a specific response of the immune system to these drugs. This kind of allergy arises as a complication in the treatment of a disease, and also as an occupational disease peculiar to people who have been working with medicines and medicines for a long time. This applies to pharmacists and health professionals in general. Statistics argue that in an urban environment, allergy to medicines is most common in women aged 30 to 40 years. This disease can occur for several reasons. It can be both hereditary factors, and the presence of other types of allergies, it is possible to blame for long-term use of drugs, and possibly simultaneous intake of several drugs. Often the reaction to medication is associated with an overdose from them, such a reaction is called pseudoallergic. Now it is known that allergic reactions can be caused by almost any medications. The most common cause of allergies are antibiotics, local anesthetics and nonsteroidal drugs to combat inflammatory processes. Once manifested, the drug allergy will occur again and again with each subsequent reception of the remedy. This type of reaction is characterized by the following symptoms: the skin begins to turn red and itch, there are rashes. The reaction time for medications varies from a few seconds to 12 hours, with the possible manifestation of such severe reactions as urticaria, an attack of bronchial asthma and angioedema. It is possible and the appearance of an allergic rhinitis and conjunctivitis. The most severe manifestation of such an allergy is anaphylactic shock, which is caused by a sharp drop in blood pressure. In the course of this shock, a person can lose consciousness and die. To understand the true causes of the emergence of a drug allergy, research can not be dispensed with. With the help of an allergist, a series of diagnostic tests is performed to determine the patient’s tolerance to certain drugs. Then the expert and gives the necessary recommendations on which of the assigned funds can actually be used.To protect yourself from a drug allergy, remember the following: 1. The name of the drug that caused the allergy should be remembered or written down. 2. It is necessary to inform doctors about their reaction to certain medications. 3. The use of an unfamiliar product must be agreed with the doctor in advance.
Allergy to objects of progress.
Today, there are a lot of things around us, which are the achievements of progress. We carry a mobile phone and a laptop, we have a TV at home, and a microwave in the kitchen. All these devices greatly facilitate our life. Only here, in some people, the creations of progress cause allergies. There were cases when a couple of hours of work at the computer was enough to cause an allergic attack. And this phenomenon has its own scientific explanation. The fact is that about 15% of people have an increased susceptibility to magnetic fields. Most likely, there are people with super sensitivity. All the technics working around – a satellite dish, a TV, a computer, is the source of the electromagnetic field. A wireless device – bluetooth, Wi-Fi and the same mobile phone does not just radiate waves, but create their own field. A complex broadband signal is unlikely to cause an allergy to an average person, but for an allergic person it can be a reason for an attack. In developed countries, radio signals are literally pervaded by everything, wireless Internet is available everywhere. But allergic people live from this unbearably. It is not surprising that in America there are cases of protest of allergy sufferers against wireless Internet. In Sweden, citizens with increased sensitivity to electromagnetic fields are even resettled in sanatoria at the expense of the state. Despite the low spread of such an allergy, the main thing that doctors call for in this case is not to panic. This allergy, like others, is treated, while quite successfully.
Allergy to meat.
Meal allergens are species-specific, their effect is markedly reduced by heat treatment. Always the most allergenic was considered chicken meat (including chicken) and pork. But for beef and mutton, the number of reactions is much less, the most neutral in this aspect of rabbit. Recently, scientists have discovered that the meat allergy is not as rare as it seemed before. The reaction is caused by the alpha-galactose substance contained in this product. It is contained in the body of mammals, causing the production of antibodies in humans. The reaction can follow 5-6 hours after ingestion, even anaphylactic shock is possible.
