There are many challenges facing health in the twenty-first century, and I see that the most important of these challenges are non-communicable diseases as well as cancer, because they are diseases that last for a long time and are difficult to cure, and often end with human death and the most dangerous thing in them is that they are caused by genetic and behavioral factors, so it is very difficult Control of these diseases and not like infectious diseases that occur due to pathogens or vectors of infection that can be controlled by eradicating them or limiting their spread. The elderly sector is the most affected by these chronic diseases, but this does not prevent them from happening to the younger groups.
The reasons that lead to human infection with these diseases:
1- The first reason is human behaviors or harmful habits that a person does, such as
Smoking, which is one of the most dangerous and most prevalent of these factors, leads to the occurrence of many cancers that often lead to death, the most famous of which is lung cancer.
Drinking alcoholic beverages also leads to a large number of cancers
Lack of physical exertion, which leads to obesity and many diseases such as high cholesterol and high blood pressure.
These reasons are subject to change and these harmful behaviors can be stopped
2- The economic situation, as poverty increases the possibility of contracting these diseases due to the spread of harmful habits such as smoking and drinking kohl.
The most common non-communicable diseases
Cardiovascular diseases are ranked first. These diseases occur due to poor diet and excessive intake of fats that increase the level of cholesterol in the blood, as well as lack of physical activity, which leads to the accumulation of these fats and also leads to obesity, which leads to high blood pressure and an increase in the incidence of clots. in the blood vessels.
Secondly, cancers, which are tumors that occur anywhere in the body due to genetic mutations, so cancer may come at any age and in any social situation, and there are some types of cancers that cannot be avoided because of the presence of genes that lead to their occurrence. The risk of getting cancer decreases.
Third, respiratory diseases, which often occur due to smoking or environmental pollution.
Fourth, diabetes is also considered one of the most dangerous non-communicable diseases, and it occurs due to a defect in the secretion of the hormone insulin or the response of cells to this hormone, and of its types:
Type 1 diabetes is caused by the immune system destroying the cells of the pancreas that secrete the hormone insulin, which leads to me not secreting this hormone.
Type 2 diabetes is caused by poor diet, obesity and lack of physical activity.
In my opinion, these are the most serious challenges facing human health in the twenty-first century.
