Diabetes first type – a disease of big cities, say researchers from the University of Cambridge. Factors of environment and genetic mutations can cause metabolic disorders and autoimmune reactions that trigger the process of cell death that synthesize insulin, one of the main hormones of the human body.
According to available data, in ecologically unfavorable areas most frequently identified cases of diabetes of the first type. The second important factor: genetic predisposition to the disease. If both parents have diabetes of any type, the risk of developing the disease their child will be raised in several times in comparison with the average.
External factors that scientists believe play a key role in the formation of autoimmune diseases, the nature of which is still poorly understood. Apparently, outside influence affects the work of genes and stimulates the human immune system to work against itself.
