Why would you have diabetes

First, genetic factors
Universally acknowledged, diabetes mellitus is a genetic disease, genetics studies show that diabetes in blood relatives with the blood relatives have significant difference, the former is five times higher than the latter.In the importance of genetic factors in the etiology of diabetes Ⅰ type was 50%, and its importance in diabetes Ⅱ type of more than 90%, thus causing diabetes Ⅱ Ⅰ genetic factors are significantly higher than diabetes.
Second, the mental factors
Nearly ten years, scholars at home and abroad confirmed that the role of mental factors in the occurrence and development of diabetes, think with mental tension, feelings of excitement and all kinds of stress state, the cause of elevated blood sugar hormone secretion, such as growth hormone, norepinephrine, pancreatic litres of sugar and adrenal cortical hormone.
Three factors, obesity
Now believe that obesity is an important cause for diabetes, and about 60% - 80% of adult diabetics are obese, before the onset of the degree of obesity and the incidence of diabetes is a fundamental research materials indicate that as we age, physical activity gradually reduce, the proportion of the human body muscle and fat is also changing.From 25 to 75 years old, muscle tissue to reduce gradually, from 47% of body weight reduced to 36%, and the fat increased from 20% to 36%, this is the elderly, especially obesity fatty one of the leading causes of diabetes significantly increased in the elderly.
Four, long-term excessive ingestion
Eating too much without restraint, nutrition surplus, make original has potential function with low insulin beta cells burden overweight, and induced diabetes.Now at home and abroad also formed a "life richer, more plump body, diabetes is increasing" concept.
In recent years, with the deepening of the understanding of diabetes research and, from molecular biology, electron microscopy ultrastructure, immunology, physiology and biochemistry and other aspects to carry on the exploration, to the etiology and pathogenesis of diabetes and a new understanding.
Five, the infection

Juvenile diabetes have significant relationship with virus infection, the infection itself does not cause diabetes, can only make contact diabetes outside show.
