Standards for gestational diabetes, so what is gestational diabetes? It refers to diabetes that either develops during pregnancy or is first detected at this stage, presenting varying degrees of hyperglycemia, including previously unrecognized glucose intolerance or diabetes prior to pregnancy. Pregnancies in known diabetic patients are not included in this category, and may also be referred to as diabetes complicating pregnancy. So, how is gestational diabetes diagnosed? We can conduct a 75g anhydrous glucose tolerance test, where a fasting blood glucose greater than or equal to 5.1 mmol/L, and blood glucose greater than 10 mmol/L one hour after, meets the criteria to diagnose gestational diabetes.
