Pregnant women with abnormal results of glucose tolerance screening and failed test results are considered to have gestational diabetes, but having gestational diabetes does not always require hospitalization. If only one of the three indicators is slightly above normal, you can regulate your blood sugar by controlling your diet and exercising appropriately. Most pregnant women can generally keep their blood sugar within the normal range if they control their diet, eat fewer and more frequent meals, and do appropriate activities. Only pregnant women whose glucose tolerance is particularly high and cannot be controlled through exercise and diet need to consider hospitalization to adjust their blood glucose, and for this group of pregnant women, if they cannot be controlled through diet and exercise, they need to consider medication to lower their blood glucose.
