For patients with gestational diabetes, it is permissible to eat dragon fruit. Since dragon fruit contains relatively low sugar levels, it can be consumed. However, it should not be eaten in excess, as excessive consumption can still lead to fluctuations in blood sugar levels. In the treatment of gestational diabetes, we should not cause the pregnant woman's weight to decrease, hence a low-calorie treatment is not advocated. Generally, the total calories are calculated based on standard weight, approximately 30 to 35 kcal per kilogram of body weight per day. Sugars should make up about 50%, proteins 20%-25%, and fats 25%-30%. It is best to divide these into three main meals and three snacks, adjusting the proportion and calorie content of the diet according to body type. Therefore, patients with gestational diabetes can eat dragon fruit, and it can be consumed as a snack between main meals.

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.

Can you eat sweet potatoes if you have gestational diabetes?

The overall principle of dietary control for gestational diabetes is to manage the total calorie intake by eating smaller, more frequent meals, dividing the day into five to six meals. This helps not only in controlling blood sugar levels but also reduces the occurrence of hypoglycemia. For patients with gestational diabetes, foods that quickly raise blood sugar, as well as those high in sugar content, starch, and fat, should be limited as these can easily convert into glucose, leading to an increased blood sugar level. Sweet potatoes, which are available in many varieties on the market, some with higher sugar content and some with lower, should be considered accordingly. Those with higher sugar content should ideally be avoided to prevent excessively high blood sugar levels, while those with lower sugar content can still be consumed. However, when eating sweet potatoes, they should be treated as a staple food, and the amount of other staple foods should be reduced accordingly to maintain good control of blood sugar levels.

Standards for Blood Sugar Control in Gestational Diabetes

The control of blood sugar in gestational diabetes mainly involves monitoring fasting blood glucose, postprandial blood glucose, and ketone bodies in urine. Patients can monitor their fasting and postprandial blood glucose 4-6 times daily. The target for blood sugar control is to maintain fasting blood glucose, pre-meal, or pre-sleep blood glucose levels between 3.3 to 5.3 mmol/L, postprandial blood glucose after one hour should be less than or equal to 7.8 mmol/L, and postprandial blood glucose after two hours should be less than or equal to 6.7 mmol/L. Ketone bodies should be negative, and glycated hemoglobin should be controlled below 6%. Only by meeting these standards can the control of blood sugar in gestational diabetes be considered adequate, which can reduce risk factors for both the mother and the fetus.

High-risk factors for gestational diabetes

High-risk factors for gestational diabetes include: women older than 35 years, those with a history of gestational diabetes, history of delivering large babies, obesity, patients with polycystic ovary syndrome, first-degree relatives with a family history of diabetes, early pregnancy checks showing fasting hyperglycemia or positive glucosuria, patients who have had multiple spontaneous miscarriages without obvious causes, fetal malformations, stillbirths, and patients with a history of delivering newborns with respiratory distress syndrome. Women with the above high-risk factors should undergo early testing for fasting blood glucose and a 75-gram glucose tolerance test to diagnose gestational diabetes and initiate early intervention.

How to control diet in gestational diabetes

Gestational diabetes is characterized by elevated blood glucose levels found during pregnancy in individuals who did not previously have diabetes. Overall, dietary control for gestational diabetes is similar to that for typical diabetes patients. It involves avoiding high-calorie, high-sugar, and fried foods. It is advisable to consume more fruits and vegetables, as well as foods with a lower glycemic index. Increasing the intake of whole grains and mixed grains is recommended, while nuts such as peanuts and sunflower seeds should be limited. Foods should be steamed rather than boiled, and fried foods must be strictly avoided.
