The screening steps for gestational diabetes involve, for most women, the recommendation to undergo a 75-gram glucose tolerance test at the hospital between 24 to 28 weeks of pregnancy. The method includes fasting blood draw, consuming 75 grams of glucose, and monitoring blood sugar levels one hour and two hours after glucose intake, to determine the presence of gestational diabetes. However, for pregnant women at high risk for diabetes, it is recommended to complete the 75-gram glucose tolerance test early in pregnancy to detect gestational diabetes early and initiate treatment promptly to reduce the risks to both the fetus and the mother.

Gestational diabetes screening time

The screening time for gestational diabetes refers to all pregnant women undergoing a 75-gram glucose tolerance test between 24 to 28 weeks of pregnancy to measure blood sugar levels and determine the presence of gestational diabetes. However, for pregnant women at high risk, including those with a history of gestational diabetes, delivery of a large fetus, obesity, polycystic ovary syndrome, a family history of diabetes, positive urinary glucose in early pregnancy, or unexplained recurrent miscarriages, fetal malformations, stillbirths, or even a history of childbirth with neonatal respiratory distress syndrome, blood sugar should be monitored as early as possible to understand the situation.

Can you drink yogurt if you have gestational diabetes?

Regarding yogurt, there are two scenarios. Currently, you can make yogurt at home with a yogurt maker. If it's homemade yogurt and you haven't added sugar, it is okay to eat because it contains probiotics and nutritious ingredients, which are actually beneficial for pregnant women. However, the yogurt sold in stores contains very high sugar levels because anyone who has made yogurt would know that unsweetened yogurt is very sour. The kind sold in stores tastes that way because a large amount of sugar is added, not to mention various additives. This is very unfavorable for blood sugar control in patients with gestational diabetes. Therefore, we recommend that pregnant women should drink less or even avoid commercial yogurt. In fact, we can obtain these nutrients by drinking regular milk, like pure milk.

Can pregnant women with gestational diabetes eat pumpkin?

The general principle for dietary control in patients with gestational diabetes is to manage total calorie intake and to eat smaller, more frequent meals. Eating five to six meals a day can not only help control blood sugar levels but also reduce the occurrence of hypoglycemia. Additionally, it is important for patients with gestational diabetes to eat less of foods that can rapidly increase blood sugar levels, as well as those high in sugar, starch, and fat content since these can easily convert into glucose, causing a rise in blood sugar. Pumpkin, for example, is a food high in carbohydrates and should be consumed in limited quantities. However, this does not mean it cannot be eaten at all. For patients with gestational diabetes, if pumpkin is consumed, it is necessary to reduce the intake of staple foods and rice, treating the pumpkin as a staple food substitute to maintain a balance of total calories and to prevent significant fluctuations in blood sugar, thus keeping it stable.

How to control gestational diabetes

Gestational diabetes refers to the onset of diabetes during pregnancy, or the first detection of varying degrees of hyperglycemia, including glucose intolerance and diabetes that were not identified before pregnancy. The risks of gestational diabetes are more severe in patients with serious conditions or poor blood sugar control, as it can easily lead to miscarriage and preterm birth, infections, and in severe cases, ketoacidosis. So, how can gestational diabetes be controlled? It can be managed through dietary control and insulin treatment. Dietary control is crucial; the ideal dietary management aims to ensure and meet the caloric and nutritional needs during pregnancy while preventing hyperglycemia or ketosis due to starvation, ensuring normal fetal growth and development. For cases where dietary management is insufficient to control diabetes, insulin is the primary medication. (Please seek professional medical guidance before using any medication, and do not self-medicate.)

Dietary Guidance for Gestational Diabetes

The dietary principles for gestational diabetes are consistent with those for non-pregnant diabetes. Firstly, the total daily caloric intake should be balanced, with carbohydrates accounting for 50%-60%, proteins for 15%-20%, and fats for 20%-30%. The overall principle is to eat smaller, more frequent meals, ideally adding two to three snacks to the three main meals per day. Common foods primarily include milk, proteins, egg whites, and fruits. Then, generally maintain the level of diet before pregnancy without overly restricting it. It is advisable to consume a significant amount of vegetables, no less than 500 grams daily, to supplement vitamins and fiber.
