What to eat the day before glucose tolerance

You should eat normally the day before the glucose tolerance test. You should not eat midnight snacks on the night of the test. It is best to ensure that you are on an empty stomach when you do the test in the morning. This will ensure that the test results are more accurate and will not affect the appearance of high blood sugar during the test. You should not eat too much sugary food the day before the glucose tolerance test, and you should not overeat. For specific dietary issues, please refer to the following.

What should you eat the day before a glucose tolerance test?

WHO recommends 75g of glucose for adults, 100g for pregnant women, and 1.75g ​​per kilogram of body weight for children. The total amount should be ≤75g dissolved in 250ml of water and taken orally within 5 minutes. Fasting blood was drawn before taking sugar, and blood was drawn every 30 minutes after taking sugar, for a total of four times. While drawing blood, collect urine every hour to measure urine sugar. A glucose tolerance curve was drawn based on the blood glucose levels at each time.

Three days before the test, the sugar content in daily food should not be less than 150g, and normal activities should be maintained. Drugs that may affect the test should be discontinued three days in advance. Three days before the glucose tolerance test, try to eat less or no sugary foods. Do not eat after dinner the day before the test and start the test the next morning. No smoking, coffee, tea or food were allowed during the entire trial.

The significance of glucose tolerance test

1. Decreased glucose tolerance: manifested as a higher increase in blood sugar than normal people, and a longer time to return to fasting levels. Such as: diabetes, hyperthyroidism, hyperpituitarism, hyperadrenalism, pancreatitis, pancreatic cancer, severe liver disease and glycogen storage disease.

2. Improved glucose tolerance: fasting blood glucose value is normal or low, blood glucose concentration does not rise significantly after oral sugar intake, and the tolerance curve is flat. It is more common in endocrine dysfunction, such as hypothyroidism, adrenal insufficiency and hypopituitarism.

3. Hysteresis tolerance curve: After oral glucose intake, the blood sugar level can return to the fasting level within a normal time, but there is a significantly increased blood sugar peak, often exceeding 10mmol/L. This situation may develop into diabetes in the future.

After passing the glucose tolerance test and confirming that you have diabetes, patients should not put too much psychological pressure on themselves. This is a common disease in life in the modern stable social environment. After suffering from diabetes, you must maintain a good attitude and actively cooperate with the doctor's treatment. The symptoms can still be controlled within a reasonable range.
