Gestational diabetes examination

The examination of gestational diabetes mainly includes oral glucose tolerance test, fasting blood glucose test and random blood glucose test. The screening of gestational diabetes is usually carried out in 24-28 weeks of pregnancy, which helps to detect abnormal blood glucose in time and take intervention measures.

Oral glucose tolerance test is the gold standard for the diagnosis of gestational diabetes, which should be performed 8-12 hours after fasting. First, measure fasting blood glucose, then drink a solution containing 75 grams of glucose, and measure blood glucose levels after 1 hour and 2 hours, respectively. If the fasting blood sugar exceeds 5.1 mmol/L, the blood sugar in one hour exceeds 10.0 mmol/L, and the blood sugar in two hours exceeds 8.5 mmol/L, it can be diagnosed as gestational diabetes if it meets any one of these criteria. The fasting blood glucose test requires not eating for at least 8 hours. If the test result exceeds 5.1 mmol/L, it indicates that pregnancy diabetes may exist. Random blood glucose testing can be performed at any time, and further diagnosis is required if it exceeds 11.1 millimoles per liter and is accompanied by typical symptoms.

Before screening for gestational diabetes, it is necessary to maintain normal diet and activities, and avoid deliberately changing living habits to affect the accuracy of results. The daily carbohydrate intake should not be less than 150 grams three days before the examination, and fasting for 8-12 hours after dinner one day before the examination. During the inspection process, avoid vigorous exercise, smoking, and drinking sugary drinks, and maintain a sedentary state until all tests are completed. If the initial screening results are abnormal, repeated testing or more detailed evaluation should be conducted under the guidance of a doctor. After the diagnosis of gestational diabetes, blood sugar should be monitored regularly and a personalized diet plan should be formulated with the help of a nutritionist. If necessary, insulin should be used under the guidance of a doctor to control blood sugar. Pregnancy blood glucose management is crucial for maternal and infant health. It is recommended that pregnant women participate in prenatal check ups on time and cooperate with doctors to complete relevant tests. Pay attention to a balanced diet in daily life, engage in low-intensity exercise such as walking appropriately, maintain a regular schedule and a good mentality. If abnormal blood sugar is found, seek medical attention in a timely manner, avoid adjusting diet or medication on your own, and ensure a safe and smooth pregnancy process.
