Clinical work often encounters the problem of obese patients’ lack of awareness of obesity, which causes difficulties in the treatment of infertility. A few phrases I often hear from obese patients are: “Am I fat?” ; “I have been fat since I was a child, my family is like that”; “She is fatter than me, but she had a baby”, etc. “With the change of economic conditions, the incidence of obesity in our population has become a surge trend, thus leading to higher infertility and complications during pregnancy and childbirth, and the incidence of obesity and diseases such as abnormal glucose metabolism after the child is born is significantly higher, and more importantly, the mother’s obesity may increase the rate of deformities in the offspring. Therefore, it is important for mothers-to-be to control their weight through strengthening exercise and reasonable diet, and preferably to keep their weight as much as possible within the normal range, to ensure the safety of mother and child and the healthy growth of the baby after birth. But often most of the patients do not pay attention to the weight on the birth to get influence, blindly eat and drink, resulting in weight gain, and even obesity, both to mother and child health laid a serious hidden danger. Therefore, both voluntary workers and patients themselves should pay attention to the impact of weight on health and make long-term hard efforts to keep their weight in a relatively normal range, which will help to obtain normal fertility and prevent the occurrence of obesity-related diseases in their offspring as adults. During your visit, if you are overweight or up to obesity standards, be sure to cooperate with your doctor for obesity-related examinations so that you can take reasonable interventions to successfully get a healthy baby and, by the way, ensure your own health.
