Allergy is the sensitivity of the immune system to a specific allergen, which can manifest itself in various symptoms and cause serious diseases such as asthma, eczema and other skin diseases. In the modern world, due to the increase in the number of allergens in the environment, the number of people suffering from allergic diseases is also growing.
The main causes of allergies include environmental influences on the body, heredity and medical procedures. The most common allergens are pollen, microbes and fungal infections, food, animal allergens, medications and cosmetics.
Allergic diseases are a serious problem for human health and, depending on their severity and duration, can have serious consequences for the body.
The key factor contributing to the development of allergic diseases and influencing their course is heredity. In persons whose relatives have allergic pathology, the likelihood of developing the disease increases significantly. The presence of an allergy significantly increases the risk of its occurrence in the future in offspring.
Among the nonspecific risk factors for the development of allergic diseases, individual characteristics of nervous regulation associated with its constitutional characteristics should be highlighted. Research also suggests that the body's functional reserves may be greater in individuals with severe allergic predisposition than in other populations.
An important factor provoking allergization of the body is the presence in the environment of a large number of new allergenic chemicals. Complex immune deficiency, caused by polymorphism of genes of immunocompetent cells and the state of autoimmune inflammation in various tissues and systems of the body, plays a significant role. Today, allergic diseases are a global problem that requires specialized treatment and recommendations for prevention.
