Gestational diabetes refers to abnormal glucose tolerance that occurs during pregnancy. It usually involves only mild, asymptomatic hyperglycemia without the typical symptoms of diabetes such as dry mouth, excessive thirst, frequent urination, and weight loss. However, significant increases in blood sugar can lead to symptoms such as dry mouth, excessive thirst, frequent urination, and weight loss. It is important to be vigilant for gestational diabetes in patients who exhibit symptoms such as excessive amniotic fluid, a large fetus, or recurrent urinary tract infections. Therefore, it is generally recommended for pregnant patients to complete an OGTT (Oral Glucose Tolerance Test) by the 24th week of pregnancy to confirm whether they have gestational diabetes. After childbirth, blood sugar levels in women with gestational diabetes generally return to normal, but the risk of developing Type 2 diabetes in the future significantly increases. Therefore, patients with gestational diabetes should undergo diabetes screening 6 to 12 weeks postpartum and be monitored over the long term.
