In 1963, Robin Coombs and Philip Jell identified 4 main types of hypersensitivity. How long have doctors known about this disease?
According to Wikipedia:
Allergy (ancient Greek. other – other, different, alien + ἔργον – exposure) – a typical immunopathological process, expressed by the hypersensitivity of the body’s immune system with repeated exposure of the allergen to the organism previously sensitized by this allergen.
The existence of the problem has been known to doctors for a long time. As far back as 3000 years ago, Chinese doctors discovered a kind of strange “autumn fever” that affected certain people every autumn, a sign of which was a severe runny nose (in modern terms, an allergy to some allergen that appears in the fall).
In the 5th century BC, Hippocrates, in one of his works, noted the appearance in some of his patients of skin rashes and severe indigestion after eating a certain product.
Galen in the second century BC described allergic rhinitis (smelling a rose, a person began to choke and sneeze).
Avicenna discovered the “spring runny nose” that struck some of his patients in the spring during the flowering of certain plants (for treatment, he suggested dripping a mummy solution into the nose, this is what they do in our time – and it helps).
Doctors started talking about allergies again only in the 19th century. In 1819, the English physician John Bostock spoke at a congress of the Medical Scientific Society with a report on a disease that worsens in some patients in the spring and summer. The doctor suggested calling the new disease hay fever… Subsequently, doctors discovered that the disease was not associated with hay, its cause was the pollen of some plants.
- More than 20,000 different allergens are known today. These are animal hair, medicines, dyes, plant pollen, food products and much more.
It is believed that the cause of allergies is the human immune system. When a foreign substance enters the body, the immune system begins to produce an immune response – antibodies that fight the danger. However, sometimes the immune system reacts very sharply to harmless substances, for example, to pollen or cat hair. We call this immune overreaction allergies.
The manifestation of allergic reactions depends on the way the allergen enters the body.
- If he penetrated the respiratory system, then an allergic rhinitis or even suffocation occurs.
- When it penetrates the skin, a rash appears on it, itching begins, and edema occurs.
- The penetration of allergens through the digestive tract is accompanied by nausea and severe stool disorders.
Allergies can be more than just unpleasant, as with hay fever. In case of an acute reaction to certain allergens, anaphylactic shock can occur, which, if not taken urgently, can very well be fatal.
People who know they have an acute allergic reaction to, say, insect bites or certain foods (seafood, nuts) often carry a disposable adrenaline syringe with them to give themselves an injection in the event of a sudden and severe allergic reaction.
There are many different allergy medications called desensitizers (drugs that decrease the body’s sensitivity to allergens).
- In recent decades, the number of allergy sufferers has increased dramatically. In Australia, the number of allergy sufferers is 9% of the total population, in Britain 7% of children suffer from food allergies. In the United States, up to 20% of adults suffer from allergies.
Some researchers of this problem believe that doctors take into account no more than 15% of all allergy sufferers; according to their calculations, only 15% to 30% of the world’s population now suffer from various types of allergies. Moreover, the increase in the number of allergy sufferers has occurred literally in the last half century.
Why this is happening, scientists do not yet know. But there are several theories to explain this phenomenon.
- Among them are “hygienic“, According to which the growth of allergy sufferers is explained by the fact that quite recently people washed themselves much less often, the human body since childhood has often been attacked by various microorganisms, and recently the development of pharmaceuticals and hygiene obstruct such” trainings. ”
- Blamed for aggravating allergy problems and significantly more frequent use various chemicals… It is also believed that antibiotics are to blame, which have been widely used in medicine and veterinary medicine for many decades.
- Even the increase in the number of cases is blamed GMO and the fact that organic products have long disappeared from store shelves, almost everything is now done with a variety of colorants, stabilizers, emulsifiers
It seems that humanity is moving step by step from normal and natural food and everyday life towards the massive use of the achievements of chemistry and microbiology, shortsightedly believing that this does not harm health.
Will humanity understand its mistake? Will he agree to at least partially return to natural food, clothing, houses, even losing comfort? Or does he decide that a short life in comfort is preferable?
