The latest flow of the health sector disease survey shows that the incidence of gestational diabetes in pregnant women is up to 17%, has doubled over the past decade or so, eating more exercise is the main reason. In clinical practice, most pregnant women with gestational diabetes are due to eating too much, eating too well, excess nutrition, as well as many pregnant women eat fruits as meals, thinking that they do not grow meat. In fact, watermelon and grapes are extremely high in sugar, and a variety of foods provide excess sugar, which in turn induces the development of gestational diabetes. In addition, most pregnant women exercise too little to consume excess sugar and other substances in their bodies in a timely manner, which also accelerates the onset of gestational diabetes. Gestational diabetes can be very harmful to the pregnant woman and the fetus. First of all, for the pregnant woman herself, it may lead to hypertension syndrome, excessive amniotic fluid, urinary tract infection, and even abnormal fetal death and miscarriage; for the fetus, it is even more harmful: in the near future, it may induce huge babies, hypoglycemia, respiratory distress syndrome and neonatal jaundice. In the long term, it may lead to obesity and diabetes in children and directly affect the development of intelligence and poor mental behavior. How can pregnant women avoid gestational diabetes? The daily diet of pregnant women can adhere to the “12345 principle”, that is, one bottle of milk, two eggs, three taels of meat, 400 grams of staple food and 500 grams of vegetables and fruits per day. In addition, it is best to choose more fruits with low sugar content, such as apples and tomatoes, as well as to do more simple household chores, yoga exercises and other activities tailored for pregnant women, you can try to do. Finally, timely diabetes screening during pregnancy is also quite important, and if high blood sugar is found, it is important to control blood sugar under the guidance of a doctor.
