Inheritance of asthma

Who suffers from asthma? Reasons.

Asthma is most common in children under 5 years, but adults can get it after 60 years.

Once diagnosed with the disease for life, although it has its remissions, periods of relapses and exacerbations. In childhood, boys are more likely to get sick, and among adults-women. This is due to some differences in the structure of the respiratory system and chest.

Is asthma hereditary?

Asthma affects people regardless of gender, race, social conditions, cultural traditions and breadth. However, there are certain factors that increase the risk of developing this disease. Among them the strongest conditions for families. If the mother or father has asthma in the family, the child’s risk of developing asthma increases. In addition, if the disease occurs in siblings, the risk in the other child increases. And so, in families where both parents have asthma, the risk of this disease in their children is about 60%, if only one of the parents has asthma, the risk is estimated at 20-40%, while higher when the mother is sick, and when both are healthy – lower by 5-10%. In the case of illness of one of the identical twins, the risk of disease of the second is 80%. Inheritance is a disease associated with genetic aspects, but in order to get asthma, in addition to genes, other factors must work.

Asthma-causes and risk factors

Asthma has been known for centuries. The first records of this disease come from papyri stored through the priests of the Egyptian pharaohs, but the social problem became only in the second half of the XX century. Since then, the world has seen a sharp increase in the incidence of asthma, mainly in highly developed countries, but more recently in third world countries. Asthma currently affects 300 million people at dawn, and that figure is expected to rise by another 100 million by 2025. Undoubtedly, this is due to the progress of civilization, which has changed the environment in which we live, affects our lifestyle and diet. On the basis of the national epidemiological study ECAP conducted since 2006, we know that in Poland, asthma is currently 4 million compatriots, that is, every 10 people. According to the Central Statistical Office, asthma is the most common chronic disease of children and young adults.

семейныйResidents of large urban agglomerations are more often ill. This is due to extreme environmental changes and the closure of sealed concrete buildings. Especially significant are the air pollution by car exhaust and wybetonowanie and asphalted land, leaving only small areas of green space in the city center. Air pollutants are toxic to the respiratory tract, but also alter the structure of pollen, making them stronger sensitizing properties. Soil insulation produces a greenhouse effect (the higher the average temperature in both winter and summer), disrupts the natural circulation of water and purifies the environment of harmful factors by their natural distribution in the soil and limits contact with the natural soil forums, which stimulates the immune system.

Asthma acquired among urban residents

On top of all this is a changed lifestyle of urban residents, with reduced physical activity, limited outdoor time and tightly closed buildings with air conditioning and a change in diet. Consume highly processed food with additives preservatives, dyes and enhancers, restriction in the diet of fresh vegetables, fruits, fish and products containing cultures of beneficial bacteria (cottage cheese, pickled cucumbers, sauerkraut) promotes immune system reactions such as allergies to potentially harmless environmental factors. In addition, there is a so-called Allergy hygiene theory. Civilizational progress, on the one hand, has changed our living conditions in terms of sanitation (current filtered and disinfected water, sewage), and medicine has made sure that we are less sick with infectious diseases due to the widespread use of antibiotics.

The immune system, which does not fight the natural enemies of man, ie. pathogenic viruses, bacteria, fungi and parasites can misinterpret signals from the environment, and as their enemies recognize the potential harmless plant pollen, house dust mites, animal allergens and against it direct its action, causing a response about the type of inflammation that has the task to destroy the enemy, but in the case of allergies causes not zdrowienie organism, but precisely the disease. It is proved that the more antibiotics are used in early childhood, the higher the risk of asthma and allergies. Remember, however, that antibiotics have saved several lives of children and adults, and mortality due to infectious diseases has decreased significantly in recent decades.

In conclusion, each of us can get allergic diseases and asthma, even if so far in our family no one was sick with these diseases, but if we live in the center of a large city, with the main transport arteries, lead a sedentary lifestyle, eat ready-made foods, have a diet poor in fresh vegetables and fruits, and willingly turn to antibiotics for each cold, our risk increases many times.
