Gestational diabetes refers to individuals who were not diabetic before pregnancy but develop high blood sugar levels due to increased insulin resistance caused by elevated hormone secretion during pregnancy. These patients also need to monitor their blood sugar, typically checking fasting blood sugar, post-meal blood sugar, and bedtime blood sugar to maintain it within a target range, such as keeping fasting levels at 5.60 and post-meal levels below 7.8 to avoid hyperglycemia or hypoglycemia and minimize the risk of low blood sugar. If the blood sugar level exceeds 10 or even higher, such patients may require medication treatment. If the increase is mild, through diet and exercise interventions, blood sugar can generally be controlled within the normal range.

Can you eat melon seeds with gestational diabetes?

Patients with gestational diabetes can eat sunflower seeds, but the amount must be controlled and should not be excessive. Each serving should be a small handful, as sunflower seeds contain a high amount of fat. Consuming too much can lead to increased blood sugar and lipids, which is not conducive to controlling blood sugar. When eating sunflower seeds, try to choose plain raw or roasted sunflower seeds, and avoid those with sweet flavors or other heavy flavorings added. Patients with gestational diabetes can also eat nuts in moderation, but the amount should be controlled to about the equivalent of two large walnuts per day, and it is best to consume them between meals.

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.)

How long does it take to recover from gestational diabetes after childbirth?

For the vast majority of pregnant women with gestational diabetes, their fasting blood glucose or glucose tolerance test can return to normal within six weeks after delivery. However, the recurrence rate of gestational diabetes during subsequent pregnancies is 50%, and about 25% to 70% of those with gestational diabetes may develop diabetes again within 16 to 25 years after giving birth. For those whose blood sugar levels return to normal after childbirth, it is also advisable to check their blood sugar every three years. For patients with abnormal fasting blood glucose or reduced glucose tolerance after childbirth, an annual check should be conducted to screen for diabetes, and they should receive strict dietary treatment and individualized exercise therapy. Therefore, the recovery time for postpartum gestational diabetes depends on the circumstances.

What to eat with gestational diabetes

The dietary control for gestational diabetes adheres to the same overall principles as non-pregnant diabetes management, mainly focusing on controlling total caloric intake and eating smaller, more frequent meals. This approach helps manage blood sugar levels and reduces the occurrence of hypoglycemia. Additionally, it is important to consider the nutrients required for fetal growth and development. Generally, carbohydrate intake should make up 50%-60% of the diet, proteins 15%-20%, and fats should not exceed 30%. Foods that quickly increase blood sugar levels and are high in fat should be consumed minimally. Instead, it is beneficial to consume a lot of vegetables, at least 500 grams daily, to ensure adequate intake of vitamins and fiber.

Gestational diabetes hazards

The hazards of gestational diabetes: So, what is gestational diabetes? It refers to the onset of varying degrees of hyperglycemia during pregnancy, or its first detection, including previously undetected glucose tolerance abnormalities and diabetes before pregnancy. However, pregnancies in diabetic patients are not included in this category, and should be referred to as diabetes complicating pregnancy. The main dangers of gestational diabetes are that it can jeopardize the health of both the fetus and the mother. The effects and hazards to offspring mainly manifest as an increased risk of fetal intrauterine death, congenital anomalies, and complications. There is also an increased risk of macrosomia, and an increased incidence of neonatal hypoglycemia, jaundice, polycythemia, and hypocalcemia. Additionally, the risk of obesity, glucose tolerance abnormalities, and diabetes significantly increases in offspring during adolescence or young adulthood.
