In the same family, it is not uncommon for the father and children to belong to the obese group at the same time. Obviously, this is first because the parents are obese and lead to children also obese genetic phenomenon. Early scientists obesity genetic problem research, some people statistics 1556 pairs (7 groups), obese couples, their next generation obesity incidence, some groups up to 87%, the lowest also reached 63%, and in the parents normal weight group, the incidence of obesity only 36%, the results confirmed that there is indeed a correlation. Familial obesity in addition to the role of congenital genes, there is another reason, is the parents’ habits affect the next generation. Obesity in general is the result of inappropriate habits of life and diet, when the habits of life once formed is difficult to change. If a couple who have developed bad habits in the process of raising children, it is inevitable that children will also live this unhealthy life, from childhood to follow the parents’ diet or work habits, the chances of obesity are relatively higher. For familial obesity, in addition to paying attention to diet and strengthening exercise in ordinary life, weight reduction surgery is also a suitable weight loss method. Our hospital once saw several pairs of patients with familial obesity, some of whom were obese and had type 2 diabetes. This type of patients basically first had their elders undergo weight loss surgery, and then after long-term physical adjustment, they found that the surgery was effective, and then recommended their children to undergo surgery to lose weight or treat related obesity-related complications.
