Patient's question:
Health consultation description: Gestational age 28+4 weeks. Tested for the Nuchal Translucency (NT) test yesterday: fasting 4.6, one hour 13.4, two hours 10.0. Since getting pregnant, I have frequently tested at home, with fasting and two hours post-meal (around 4 to 5, never exceeding 6) all being normal. Yesterday evening, I tested two hours post-meal at home and got 4.6. Today at noon, I tested two hours post-meal at home and got 5.2. But why was my blood sugar so high after drinking the glucose solution for the NT test at the hospital yesterday?Help needed: My home glucose tests during pregnancy are all normal, but my glucose tolerance test at the hospital is very high. What should I do?
Doctor's answer:
Diabetes diagnosis includes one of the following criteria: fasting blood glucose greater than 6, or a two-hour post-meal blood glucose (oral glucose tolerance test) greater than or equal to 11.1, which can confirm diabetes. A level greater than 7.8 but less than 11.1 indicates impaired glucose tolerance. Your hospital's careful examination of the oral glucose tolerance test shows such a high result, so attention should be paid to dietary restrictions. Measuring blood glucose at home may be inaccurate due to improper food intake. It must be ensured that the first and second meals consist of 75 grams of glucose powder, and blood glucose should be measured two hours later for accuracy. It is likely that your self-measured blood glucose is inaccurate. Follow a restricted diet, avoid sweet and overly greasy foods, engage in appropriate physical activity to enhance glucose metabolism, and perform periodic re-examinations of glucose tolerance and blood glucose levels.
