What is Gestational Diabetes? How to prevent gestational diabetes? Gestational diabetes not only poses a double threat to mothers and babies, it is not only one of the triggers for obstructed labor and cesarean section, but also increases the chances of infections during pregnancy and so on, and to the fetus, it can cause postnatal hypoglycemia, jaundice and other problems. Diabetes is a common chronic disease, for ordinary people, the occurrence of diabetes, is caused by very complex factors. As for pregnant women, they are prone to diabetes as their weight increases and some hormones and cytokines produced by the placenta interfere with the normal work of insulin in the body after pregnancy. To prevent gestational diabetes, expectant mothers need to control their weight. It is understood that there are two kinds of gestational diabetes, one is diabetes before pregnancy, called diabetes combined pregnancy. The other type is when a pregnant woman develops diabetes only during pregnancy, called gestational diabetes, and most patients fall into this category. Although most cases of gestational diabetes return to normal after delivery, the chances of developing type 2 diabetes in the future are greatly increased. Most importantly, gestational diabetes also has many harmful effects on the baby, such as fetal gigantism and malformations, which must be prevented early in life. The occurrence of gestational diabetes is complex, and current scientists have not yet found the exact cause, however, they have found some clues about the mechanism of diabetes and what people belong to the high-risk group. Age and obesity: Obesity increases insulin resistance thus making a person susceptible to diabetes. Hormonal problems: Normally, three times the usual amount of insulin is produced during pregnancy. However, in exceptional cases, the body fails to produce enough insulin. Scientists believe that this is one of the main causes of gestational diabetes. Genes and family history: Family history is a major causative factor for gestational diabetes. Gestational diabetes can be very harmful not only to the pregnant woman herself, but also to the fetus itself. For obese pregnant women, we should pay special attention to postpartum obesity, do not believe in acupuncture and other weight loss methods, improper weight loss is easy to rebound, the need for scientific development of weight loss methods.
