Glucose screening is short for gestational diabetes screening and is very necessary. Of course, if conditions allow, you can also just have a glucose tolerance test, but if not, it is recommended that all pregnant women need to have a glucose screening test between 24-28 weeks of pregnancy. The glucose screening test is done to assess the risk of gestational diabetes. Due to factors such as changes in body hormone levels and healthy diet, pregnant women are more likely to develop diabetes than usual, and the incidence of gestational diabetes is still increasing year by year, so pregnant women should have their blood sugar tested in a timely manner. The clinical manifestations of gestational diabetes are often not obvious, but it has a great impact on the pregnant woman and the fetus. Gestational diabetes may increase the risk of fetal miscarriage, malformation, and giant baby, which are harmful to the pregnant woman and the fetus in many ways and may seriously endanger the life of the mother and the baby. If the glucose screening result is abnormal or the pregnant woman has diabetes risk factors, such as family history of diabetes, high weight, etc., a glucose tolerance test, or OGTT, is also needed to further clarify whether the pregnant woman has gestational diabetes. In daily life, it is recommended that pregnant women pay attention to the intake of nutrition in their diet, pay attention to the supplementation of high-quality protein, such as lean meat, fish and shrimp, dairy products, soy products, etc., and avoid a high-sugar and high-fat diet to reduce the risk of hyperglycemia during pregnancy. If gestational diabetes is clearly diagnosed, early intervention, early treatment and early benefit are recommended under the guidance of a doctor.
