A few days ago I received a good news, a female fat friend who underwent weight loss surgery two years ago finally succeeded in becoming a mother, and sent a weibo overflowing with that happiness between the lines. You know, in the traditional Chinese culture, if a woman can’t get pregnant after 5 years of marriage, how much psychological pressure she has to bear! Before deciding to undergo weight loss surgery, she tried Chinese herbal medicine, hormone therapy, IVF, and even various secret recipes, spending money and suffering, all to no avail, until one day an internist recommended weight loss surgery to her, because obesity was the root cause of her infertility, and any treatment without weight loss was useless. The incidence of infertility has been increasing in recent years, and there are many causes of this disease, including genetics, the environment, psychology and the effects of other diseases, but obesity has become an increasingly important cause. Studies have found that obese women are often accompanied by various endocrine disorders, followed by irregular menstruation, increased androgens, hirsutism, non-ovulation, polycystic ovary syndrome, which can lead to infertility or habitual abortion. In the case of obese men, there is an increase in estrogen levels, a decrease in sperm quantity and quality, a decrease in libido and erectile dysfunction, which leads to infertility. In addition, the risk of “three highs” during pregnancy will also increase, with a high rate of miscarriage and a higher probability that the future baby will be a little fat. Therefore, losing weight before pregnancy not only makes it easier for women to get pregnant, but also makes it safer for mother and child. Therefore, when other causative factors are ruled out and it is clear that infertility is caused by obesity, weight loss becomes the most effective treatment. And when other weight loss methods are ineffective, and weight loss surgery becomes the only option. Of course, there are many fat people who are worried about the future effects of weight loss surgery on their children, and to be honest, this used to be my concern, but more than ten years of clinical experience has confirmed that after surgery, as long as the vitamins are strictly supplemented and the diet is reasonable, it is safe for both the mother and the child. At least 20 of the women I have treated have become mothers with healthy babies, and these mothers have given me the nickname “The Goddess of Delivering Children”. Of course, not all infertile women are suitable for weight loss surgery, and it is recommended in China that surgeon intervention be considered only when the body mass index is >28 or more, and it is also recommended that women who undergo weight loss surgery should consider pregnancy at least one year after surgery, which is safer. Therefore, there is a kind of infertility called obesity in this world, and there is a group of “child delivery” called bariatric surgeons.
